Julie Andrews & St. John

Paul the Deacon

Paulus Diaconus (c.720-c.799) wrote the hymn of St. John, and it goes like this:

Ut queant laxis resonāre fibris
Mi ra gestorum famuli tuorum,
Sol ve polluti labii reatum,
Sancte Iohannes.
So that your servants may,
with loosened voices,
resound the wonders of your deeds,
clean the guilt from our stained lips, O Saint John!

What does this have to do with Julie Andrews? Nothing, until the 11th century, when Guido of Arezzo (c.992-1050) proposed an ascending diatonic scale for music.* He realized that the hymn was a perfect mnemonic for the scale, and so he described the scale using the syllables on which the ascending tones fell: ut, re, mi, fa, sol, la. Around 1600, in Italy, a musicologist named Giovanni Battista Doni refined the scale by changing "ut" to "do" because he preferred the open vowel sound it created, and added a seventh note which he called "si" because of the SI initials from "Sancte Iohannes." So we had do re mi fa sol la si.

It was a long time later that a Norwich, England music teacher named Sarah Glover (1785-1867) developed a method she called Sol-fa for teaching a capella singing, and changed si to ti so that each syllable would start with a different consonant sound.

Glover published her ideas, and they were further refined (and sometimes independently developed) by people like John Curwen, Pierre Galin, Aimé Paris, Emile Chevé. I cannot draw a direct line from any of these to Rodgers and Hammerstein, but by the time R&H came along, "singing the scales" was a commonplace way of teaching the rudiments of music to children. When R&H needed a number for a scene in the 1959 musical "The Sound of Music" when Maria teaches the children to sing—after discovering they knew nothing of singing because their father had forbidden it—what was more natural than using the sung scales that had been developed over the past thousand years? Hammerstein turned each note to a homonym to flesh out the lyrics, and the rest is theatrical/cinematic history.

Hammerstein should be grateful that he didn't have to write a lyric for "ut."

*"Ascending" is important here: previously, the scale was described as a series of descending notes.

Alcuin, Puzzle-master

Is there anyone who hasn't heard the puzzle of the fox, the goose, and the bag of corn? A man has to transport these three things across a river in a boat which can hold him and one other item. His constraints are that he cannot leave the fox and goose together, or the goose and corn together. This is one of several river-crossing puzzles that exist in different cultures. The earliest version we know of in print is in a late 9th century Latin manuscript of the work Propositiones ad Acuendos Juvenes (Problems to Sharpen the Young), attributed to Alcuin of York (c.735-804).*

"Alcuinus abba"=Father Alcuin

Educated in the cathedral school of York, Alcuin became a monk and teacher. On his way back to England from a trip to Rome in 781 he met Charlemagne, King of the Franks, who recognized Alcuin's erudition and invited him to stay and help promote learning to a level unknown since Rome.

Alcuin became head of the palace school at Aachen, where he established a great library, revised the liturgy, wrote treatises and poetry and works on grammar. It is his influence on learning that is said to have vaulted Latin into the position of being the academic language.

Propositiones ad Acuendos Juvenes is attributed to Alcuin, because of its date and because it is the kind of work he would have created for the pupils at Aachen. The 50+ puzzles in it are very mathematical, with three river-crossing problems—although in his early example the items are a wolf, a goat, and a cabbage. Solutions are provided for all the problems.

Or almost all. There is one that has no solution offered, and it goes like this:

A certain man has 300 pigs. He ordered all of them slaughtered in 3 days, but with an uneven number killed each day. What number were to be killed each day? (Problem 43)

There can be no solution to this puzzle, for obvious reasons. (Feel free to post the reason why in the comments to explain it to your fellow readers.) The assumption is that it was given to difficult students to frustrate them.

*Alcuin also recorded the destruction of Lindisfarne.

The Birth of Tick-Tock

A city without bells is like a blind man without a stick. —Rabelais

Rabelais (c.1494-1553) was a little late for this blog, but his statement in Chapter XIX of Gargantua indicates a reliance on time-keeping that the modern world can understand. It was not always thus, however, for the Middle Ages.

I discussed yesterday how early concepts of time by their nature might have made it difficult to think of time as something measurable. I mentioned a mid-1200s definition of time that came from Franco of Cologne, the mathematically-minded music theorist who created what is the basis for modern musical notation. Franco's most diligent biographer places him as chapelmaster at Notre Dame in Paris.

Johannes de Sacrobosco (c.1195-c.1256) taught at the University of Paris, probably contemporaneously with Franco. Johannes was an astronomer who, among other things, declared that there was a flaw in the Julian calendar: it was 10 days off. (That error wouldn't be corrected until long after.) He also wrote of an attempt he knew to construct a wheel that would make a complete rotation in one day. Robertus Anglicus wrote a commentary in 1270 on Sacrobosco's treatise, mentioning the device and further spreading the idea. In that same decade, a clock is described by someone writing in Spain that runs by the flow of mercury from chamber to chamber in a wheel.

It only took a generation for this idea to catch on. By 1300, clocks were becoming widely known (if not widely owned), but the early ones only measured hours—they rang bells, but had no faces with markings around a dial, no minutes or seconds were counted, that we know of.

The device described by Sacrobosco and Anglicus used a weight hanging from a line around a wheel or cylinder. The Middle Ages understood wheels, gears, levers and pulleys, but how could these be used to guarantee a steady revolution of the weighted wheel? Sometime around 1300, or not long after, some early mechanical "Eureka" moment took place. Someone designed what we call the "escapement," which rocked back and forth on a toothed gear, allowing the wheel to turn at a steady, measurable, predictable speed. It also had a side-effect: a steady sound that we have been listening to ever since.

The escapement.

Within a generation after 1300, Dante Alighieri (c.1265-1321) considers his audience familiar enough with clocks and their mechanism to use gears as a metaphor:

As the wheels within a clockwork synchronize
       So that the innermost, when looked at closely
       Seems to be standing, while the outermost flies. (Canto xxiv, Paradiso)

Humans could now mark time in sequences of ticks and tocks. Minutes and seconds could be distinguished. Hours could be regulated. Six hours before noon became the same, whether it were dark in winter or already light in summer. (That's right: the 12 hours from sunrise until sunset used to be extended or shortened depending upon the season.) This was a change from the canonical hours described by the Rule of St. Benedict, for whom prayers at Matins were supposed to end as the sun rose, and therefore had to be started at different times depending on the season. In 1370, Charles V of France installed a clock in his palace, and decreed that all clocks in Paris be set according to his. Punctuality, crucial feature of our modern world, was born.

What is Time?

What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not: yet I say boldly that I know, that if nothing passed away, time past were not; and if nothing were coming, a time to come were not; and if nothing were, time present were not. Those two times then, past and to come, how are they, seeing the past now is not, and that to come is not yet? But the present, should it always be present, and never pass into time past, verily it should not be time, but eternity.

With this passage, found halfway through Book XI of his Confessions, St. Augustine of Hippo (13 November 354-28 August 430) discussed the difference between Time and Eternity. He knows that he is not aware of time that is yet to come, or time that is past; only time that is present; but he still doesn't know how to define what time is.

A medieval 24-hour clock.

Measurement of time was imprecise. There were "hours" of the day: the Vigil took place between 2:30 and 3:00 a.m., Matins came at Dawn, et cetera. These hours designated times of worship and work for monks and were extended to general use, but they were not exactly a way to quantify time. The hour of Sext was at noon, for instance, which was recognized when the sun was highest, but Matins/Dawn came more or fewer hours before Sext, depending on the time of year. They were segments of the day that altered with the seasons; they did not measure a span of time.

St. Benedict of Nursia (c.480-543), in his Rule for monks, intends them to worship at specific times, and finds a way to measure a span of time. Monks were not to slack at getting up for Matins, and so:

If anyone shall come to matins after the Gloria of the 94th Psalm, which on this account we wish to be said slowly and leisurely, he shall not take his place in the choir, but go last of all, or to some place apart which the abbot may appoint for those who so fail in his sight.

Time could be measured, therefore, by comparison to a known duration.* But even durations could be tricky. Augustine had pondered thinking of a long syllable as equivalent to two short ones, "But when two syllables sound one after the other—the first short, the second long—how shall I keep hold of the short one?" Augustine seemed to be caught up in the idea that time was a continuum, and that he was living in a constant present and could not treat the past and future in the same conceptual way, since he could not live in them. The Middle Ages couldn't grab time and measure it, like water or distance or even acceleration. It was insubstantial, and belonged to God.

The concept of time had to change ... and eventually it did. There was no clear turning point; there had to be some conceptual change, planned or otherwise, to see time not as a line but as a series of points, as separate moments that could be thought of without being linked to a past or future moment.

Sometime in the mid-13th century, we find Franco of Cologne. He was a music theorist who gave us the idea that a mark on a page should distinguish how long a note should be. This was the logical extension of Franco's definition of time: "Time is the measure of actual sound as well as of the opposite, its omission."

Was this the moment? Was it music, with its attention to and reverence for mathematics that accidentally inspired the thinking of time as separate units that could be measured and counted? We might be able to believe that, if there were some evidence that the world began to measure and quantify time; for instance, if the development of mechanical clocks were to start around this time.

Well, guess what happened next?

*This method of measuring spans of time without a clock is used even today.

Jan Hus, Part 2 (of 2)

[The first part to this is here.]

Jan Hus (c.1369-6 July 1415) was enamored of the ideas of John Wycliffe, creating controversy for Bohemia when the church hierarchy decided that Wycliffe's ideas were heretical. King Wenceslaus IV—perhaps alarmed that Prague was becoming the center of church controversy—tried to reconcile the opposition with a synod in 1412. The synod was a failure: arguments persisted, and Hus and his followers refused to accept the absolute authority of the pope.

Hus, never one to lie low, wrote De Ecclesia (On the Church, much of which was lifted from Wycliffe's writings) in 1413, in which (among other things) he challenged the authority of the pope. (Somewhere, Wenceslaus IV was sighing; but he had worse ahead for him.)

Ultimately, the Council of Constance (1 November 1414) was assembled to deal with the ongoing papal schism and other issues. It was called by Wenceslaus' brother, Sigismund of Hungary. The debates began. After several weeks the rumor was spread that Hus intended to flee; in December he was imprisoned by the church. Sigismund was angry because he had promised Hus he would be safe, but the church officials convinced Sigismund that a promise to a heretic wasn't binding.

Hus was passed around, finally spending two and a half months in chains. His trials for heresy took place in June 1415, during which (as was customary) he was not allowed to have any defense. He offered to recant if he could be proven to be in error. Of the several points on which they demanded he recant, he asked that they not expect him to recant things he had never espoused; also, as a matter of conscience, he refused to recant points they said—but could not convince him—were errors.

On 6 July, 1415, Hus was led into the cathedral where, after a High Mass and a sermon on the need to eradicate heresy, he was condemned publicly and led outside, where he was clothed in his priestly vestments so that they could strip them from him. Still refusing to recant, he was burned at the stake and his ashes were thrown into the river.

Jan Hus, Part 1 (of 2)

Jan Hus (1369-6 July, 1415) was a pious child whose manners and performance while singing and serving in church in Prague distinguished him. He earned his baccalaureate at 24 and his master's at 27 from the University of Prague. He was ordained in 1400, and became rector of the university in 1402.

Hus was greatly influenced by the writings of Wycliffe. While Hus was rector, dozens of Wycliffe's ideas were branded heretical by the church authorities. That didn't frighten Hus away from Wycliffe's works, and he translated Wycliffe's Trialogus into Czech. The Trialogus was a conversation between three individuals: Alithia (Truth) and Pseudis (Falsehood), with Phronesis (Wisdom, the voice used by Wycliffe to present his answers to sticky doctrinal questions). Among the many points discussed in the work, Wycliffe challenged the church's teaching on transubstantiation (previously mentioned here), the idea that the consecrated bread and wine at Mass are converted to the body and blood of Christ. Wycliffe's disagreement with the church on this was based on his logic that bread and body must still both exist, and that they cannot simultaneously occupy the same place.*

It signifies, [...] one and the same - as though, for instance, he should make the person of Peter to be one with Paul... For if A is identical with B, then both of them remain; since a thing which is destroyed is not made identical, but is annihilated, or ceases to be. And if both of them remain, then they differ as much as at first, and differ consequently in number, and so are not, in the sense given, the same...

Hus shared these observations, and like Wycliffe began to preach against what he saw as the corruption and moral failings of the church hierarchy. In 1406, when some Bohemian students brought to Prague a eulogy for Wycliffe bearing the seal of Oxford University, Hus read it proudly from the pulpit. By this time, it was known that King Wenceslaus IV was tolerant of non-conformists. Pope Gregory XII, getting wind of all this, sent a stern warning about Wycliffe's heretical works and the king's attitude. The king and the University of Prague both stepped backed from the preaching of Wycliffe and Hus.

In December 1409, Pope Alexander V issued a papal bull against Wycliffism. Hus appealed to Alexander in 1410, but in vain. All available works of Wycliffe were rounded up and burned, Hus and his followers were excommunicated. Bohemia sided with Hus against the Pope. (This was easier to do since Alexander was the third man currently considering himself a pope; but that's another story.) Like Wycliffe being supported by his friends and powerful political allies, Hus survived a few attacks by the church. Eventually, however, his luck and support would run out.

What Ales You

Beer/ale has been brewed since the days of the Roman Empire. I suppose we should say that ale has been brewed that long, and beer came later. Originally made with barley, and then later with different grains, it was only around 1500 that the practice of adding hops to the mixture became popular. Although the word beer is almost as old as ale, the Middle Ages used the different words to distinguish between the much more common ale without hops and beer, made with hops.*

Mashing up grain, letting it sit in water with yeast, then letting it ferment was easy to do and produced a drink that provided calories, hydration, and not a debilitating amount of alcohol. Spices were sometimes added for variety. At a time when water was not always potable or easy to come by, turning it into a tastier drink was a desirable goal, easily accomplished by many households. And brewing would have been an ongoing process: hops provide preservative qualities that ale would lack. Given, however, that ale was drunk on a daily basis by almost everyone, frequent brewing would have been planned, and the more the better, because selling excess was a great way to make some extra cash.

Because ale (and later beer) was such an essential commodity, regulations for controlling prices, amount, and quality abound. Records of fees levied reveal the large number of women involved in the process. In fact, it is fair to say that brewing was a woman-dominated career in the Middle Ages at least until the Black Death, and for most of the rest of that century. Every village and hamlet probably had women who provided most of the ale to those who did not brew their own.

The introduction of hops changed the industry as well as the drink. Hopped beer could last longer, and it was therefore efficient to brew it in mass quantities. The equipment needed for this required a larger outlay of capital, which the cottage-industry alewife could not afford. Also, brewing in large quantities was more labor intensive and could not easily be squeezed into the day by the woman who had other domestic chores to attend to. The brewing of hopped beer became a town-centered industry dominated by men; where women were involved in the new model, it was as distributors.

If this post has whetted your appetite for historical ale and beer knowledge, consider this or this.

*Search the Internet for when hops started being used and you will find a wide variety of answers. Trivia: The Middle Ages Brewing Company (in Syracuse, NY) website says "Come and see ... British style 'real ale' brewery." Do you suppose they really leave out the hops?

Robert Cotton's Hobby

Sir Robert Bruce Cotton was born 22 January, 1570 (or 1571). Too late to be part of the Middle Ages, but still a subject for this blog; you'll see why presently. He attended the Westminster School on the grounds of Westminster Abbey in London, considered one of the finest schools in England. From there he went to Jesus College, Cambridge, graduating with a BA in 1585.

In 1601 he was made a Member of Parliament and started a successful political career. He helped King James I develop a new fund-raising scheme with the invention of the title/position "baronet." A baronet (like a knighthood) did not confer on the bearer a right to attend Parliament (and therefore be a potential nuisance), but it was a lovely and impressive title that could be inherited; many wealthy men would willingly pay large sums to be made a baronet, which gave them a hereditary title for their childfren but no real power.

Despite Cotton's friendship and value to the king, he began to become a concern when his views about the importance of parliament over the monarch were expressed in his published essay The Dangers wherein the Kingdom now standeth, and the Remedye. The monarchy considered this a threat, and they decided to take action to prevent Cotton from becoming the center of discontent. The monarchy had a simple solution to pull the rug out from under Cotton: confiscate his library.

The assumption was that his library held documents that might provide historical precedents for his political views. Why was his library such a concern? Robert Cotton had a hobby: for decades he had been collecting documents, manuscripts, books, records. He had an insatiable desire to collect and preserve the history of the written word in England, and he created a library with more documents (it was said at the time) than the Records Office in London. It was confiscated by the king in 1630. Cotton died in 1631. The library was eventually returned to his family; his grandson gave it to the British Library.

The Cotton Library was, of course, pre-Dewey Decimal and pre-Library of Congress. He had his own scheme for organizing documents. His library was lined with bookcases, each of which was topped by the bust of a classical figure. Each bookcase had up to 6 shelves, designated by letters. Each shelf was filled with documents, counted from left to right. Items in the library were designated by bust/shelf/#document. For instance, the Anglo-Saxon Chronicle (one of nine surviving manuscripts) is designated Cotton Domitian A.viii. Many works of literature from the Middle Ages, such as Beowulf (Cotton Vitellius A.xv) or Sir Gawaine and the Green Knight (Cotton Nero A.x) exist today only because they were collected and preserved thanks to Robert Cotton's hobby.

Lindisfarne

In 635 CE, St. Aidan (c.?-651) was sent from the monastery on the island of Iona by King Oswald to re-Christianize England. He chose to found a monastery on an island off the northeast coast of England. Although it is mentioned in the 9th century Historia Brittonum (History of Britons) by the Welsh name of Medcaut (Healing), perhaps because of a reputation for medicinal herbs, it is more commonly known as Lindisfarne. Lindisfarne is a tidal island, meaning it is accessible by a causeway only when the tide is out. St. Aidan thought that this would provide security for the peaceful community of monks.

Aidan was given a horse by Oswald, so that he could ride to the nearby communities to preach. Legend says he gave the horse to a beggar and walked from village to village, speaking quietly and simply to the inhabitants, spreading the message of Christianity that had once been brought to England by Romans, but had been replaced after the fall of Rome by Anglo-Saxon paganism.

The night St. Aidan died, a teenager had a vision that inspired him to become a monk. He was made prior of Lindisfarne in 665 and bishop in 684. When he died in 687, St. Cuthbert (c.634-687) was made the patron saint of northern England.

A Viking raid on northeast England in June of 793 was bad news for Lindisfarne. The Vikings had no respect for the peaceful monks, and did great damage to the Priory. Alcuin of York, a highly respected scholar in the court of Charlemagne at the time, wrote:

Never before has such terror appeared in Britain as we have now suffered from a pagan race. . . .The heathens poured out the blood of saints around the altar, and trampled on the bodies of saints in the temple of God, like dung in the streets.

More raids in 875 led to the abandonment of the island by the monks, who carried away as much as they could, including the remnants of St. Cuthbert.

Now it has a population of fewer than 200. It is largely a nature reserve and a destination for tourists who visit the ruins of the priory and a small Tudor fort turned into a castle.

Leechbooks

A leechbook was a collection of remedies, called so because a physician or surgeon was called a "leech." Bald's Leechbook is a very early (9th century) example.

It contains the only known plastic surgery procedure in an Anglo-Saxon text:

For hare lip, pound mastic very small, add the white of an egg, and mingle as thou dost vermilion, cut with a knife the false edges of the lip, sew fast with silk, then smear without and within with the salve, ere the silk rot. If it draw together, arrange it with the hand; anoint again soon.

We don't know if this is just theory, or if it were actually put into practice with the desired results.

Bald was not the author, and not likely a medical man. A Latin colophon at the end states:

Bald habet hunc librum Cild quem conscribere iussit
"Bald owns this book which he ordered Cild to compile."

Cild may have been someone with medical experience as well as being the organizer of the book, or he may have simply been a copyist who brought together various sources for Bald. Two doctors are mentioned in the book, Dun and Oxa, but we don't know much else about them.

The leechbook is organized into two volumes, dealing respectively with external (such as skin, teeth, or ear) and internal (such as upset stomach, jaundice, or vomiting blood) problems. The surgery is in part one. This organization is different from many other leechbooks and collections of knowledge, which often gather together every bit of lore known to the author without much regard for categorization. Another collection is a late 10th/early 11th century manuscript named Lacnunga (Anglo-Saxon for "Remedies") by its 19th century editor. It uses Anglo-Saxon and Latin to list medical knowledge, remedies (some the same as in Bald's), prayers, charms and incantations, and some Old Irish poetical prayers for health.

Both are found in the British Library. A 19th century searchable edition of Bald's can be found here.

The English Bible

John Wycliffe (c.1320-1384) was politically active and a reformer whose brilliance as a theologian was originally admired widely. Eventually, as some of his ideas began to be put into practice, he became labeled a heretic. One of his greatest (and, in the church's opinion, most heretical) acts was to produce a complete translation of The Bible into English, because "it helpeth Christian men to study the Gospel in that tongue in which they know best Christ’s sentence."*

"In ye bigynyng iwas ye word", Wycliffe Bible.

We are pretty sure that Wycliffe didn't do the whole book himself. Nor was he the first: the Bible had been translated into Old English centuries before Wycliffe, but manuscripts were rare and piecemeal. The Venerable Bede (c.673-735) and Aldhelm (c.639-709) had each translated parts of the Bible into Old English. The oldest existing manuscript we have is the Lindisfarne Gospels, a 10th century Latin text of Matthew, Mark, Luke and John with Old English translation inserted between the Latin.

Many so-called Middle English Bibles were in fact paraphrases or commentary rather than strict translations.

For Wycliffe, the Bible held more truth than the church hierarchy, and he wanted people to be able to directly study the word of God. When the church objected—the traditional approach was that the clergy were best suited to explain the Bible to the people—Wycliffe replied “Christ and his apostles taught the people in that tongue that was best known to them. Why should men not do so now?”

So he set about making a careful translation with his friend, Nicholas of Hereford. Although using familiar English words, they stuck to Latin syntax, and so a sentence that we know as "And God said, Let there be light, and there was light." which is a fairly sensible translation of the Latin, came out (following Latin word order) as "And God said, Be made light, and made is light." In the years after Wycliffe's death in 1384, a follower of his (probably John Purvey) revised it, changing the word order to "And God said, Light be made, and light was made."

The Bible was popular—over 250 copies exist—but the church objected to it and to Wycliffe's increasing influence on the common people, especially after the Peasants' Revolt and the increasingly vocal and active Lollard movement. The early 1400s saw some extremely strict censorship laws put into place to prevent any more unauthorized translations. The problem was that, since the Wycliffe Bible had been translated from the Latin (whether carefully or not) without editorializing, it was not easily distinguishable from "authorized" translations. This may be why so many copies survived. Of course, 1453 and Gutenberg were just a couple generations away, which meant that the production of "unauthorized" texts was about to become frighteningly easy.

*N.B.: "sentence" in the Middle Ages did not mean just a collection of words expressing a complete thought. From the Latin sententia, it signified concepts such as "meaning" or "thought" or "opinion."

Fireworks

In honor of Independence Day in the USA...

Everyone knows that to discuss the history of fireworks means talking about China and Marco Polo (1254-1324), but the real history of fireworks in the European Middle Ages may start with Roger Bacon (1214-1294).

Bacon was a Franciscan Friar who spent time at Oxford and may have studied under Robert Grossteste. He has been called the first user of the scientific method, but more careful study of his works suggests that his conclusions and theories were the result of "thought experiments" like many other scholars, instead of actual scientific experimentation. Although Oxford's fairly careful and complete records of degrees given do not show that Bacon ever earned a doctorate, he was nicknamed Doctor Mirabilis (wonderful doctor) for his ideas.

Many volumes have been filled about Bacon, his ideas and discoveries, but today we are interested in gunpowder. At the request of Pope Clement IV, Bacon wrote his seven-part Opus Maius (Greater Work) which discussed (among other things) his thoughts on philosophy, theology, and certain scientific experiments. We know that a contemporary and fellow Franciscan, William Rubruck (c.1220-c.1293), visited the Mongols and witnessed the use of gunpowder in the form of firecrackers. Perhaps Rubruck brought some back. The relevant passage in the Opus Maius is:

We have an example of these things (that act on the senses) in that children's toy which is made in many [diverse] parts of the world; i.e. a device no bigger than one's thumb. From the violence of that salt called saltpetre [together with sulphur and willow charcoal, combined into a powder] so horrible a sound is made by the bursting of a thing so small, no more than a bit of parchment [containing it], that we find [the ear assaulted by a noise] exceeding the roar of strong thunder, and a flash brighter than the most brilliant lightning.

The "no more than a bit of parchment containing it" reminds me of these. He speaks of this again in his Opus Tertium (the Third Work; and yes, there had been an intermediate Opus Minus, the Lesser Work):

Then wonders can be done by explosive substances. There is one used for amusement in various parts of the world made of powder of saltpeter and sulphur and charcoal of hazelwood. For when a roll of parchment about the size of a finger is filled with this powder, it produces a startling noise and flash. If a large instrument were used, the noise and flash would be unbearable; if the instrument were made from solid material, the violence would be much greater.

These are the earliest references in the English-speaking world to gunpowder and fireworks. Whether Bacon ever made his own gunpowder is unknown, however. Some articles will tell you that he could, and encrypted the knowledge in order to prevent its misuse. Claims that Bacon hid the formula for gunpowder in his works cannot be substantiated, however. He seems to know what goes into the formula, but not necessarily in what proportion.  The secret numbers that some modern manuscript detectives claim to have found in his writings produce the wrong ratio for gunpowder to do more than smoke.

Enjoy your day.

Wycliffe the Reformer

John Wycliffe (c.1324-1384), first discussed yesterday, started his career as a respectable Oxford scholar and theologian. His religion and study taught him that wealth was not needed for a Christian life, and not appropriate for the clergy. This was not a radical idea, or new—Francis of Assissi had been preaching and embodying the ascetic life almost 200 years earlier*—however, his arguments and his public presence and patronage made him notorious.

It was after the conference at Bruges (mentioned briefly in the above link) that he seems to have decided he needed to make a more overt defense of his views. Wycliffe might have been fine keeping his views in the rather private academic arena, but when he was denounced and challenged in public by William Bynham of Wallingford Priory in Oxford, Wycliffe decided to go public with his Summa Theologiae in which he explained why the church should not have temporal authority, and that the king was above the pope in earthly matters. He followed this with De civili dominio (On civil lordship), in which he stated that if the church should abuse any of its temporal holdings, the king should take those holdings away; not to do so would be remiss. It was the strongest argument (and the most welcome, to members of the nobility) for the king's authority over the church.

The monastic orders, who benefited from the feudal system of rents and tenants, were understandably threatened by this, especially considering the patronage Wycliffe enjoyed from men like John of Gaunt, who was effectively the ruler of England during Edward III's decline. When Wycliffe was summoned before Bishop William Courtenay of London, he was accompanied by John of Gaunt, the Earl Marshal Henry Percy, other nobles, and even some friars of the orders that rejected personal possessions. Gaunt's presence cowed the bishop, and the gathering broke up without immediate consequence for Wycliffe. This pattern, of attempts to chastise or reign in Wycliffe being overwhelmed by his supporters, would be repeated more than once in the years to come.

In fact, Wycliffe's views were so popular in England that they sparked the anti-establishment movement called "Lollardy" about which it was supposedly said at the time "Every second man that you meet is a Lollard." It is certain that the citizens involved in the Peasants' Revolt were familiar with his views on equality, although he disapproved of their violence. It is ironic that Wycliffe's most powerful patron, Gaunt, was also one of the chief targets of the mob because of his aristocratic standing. It was not long after the Revolt that Wycliffe was officially being denounced as a heretic, which complicated his life but didn't stop him from writing. As well as other tracts and letters, he had one more major work he wished to produce that would shake the church to its foundations. He decided to do what had never been done before: translate the entire Bible into English.

*Umberto Eco's The Name of the Rose is remembered as a murder mystery set in 1327 by many readers who have forgotten that one of the central themes is the philosophical debate on the topic of the church and material wealth.

Wycliffe in Politics

A church reformer gets his start.

We don't know a lot about the early years of John Wycliffe (c.1324-1384). There were likely a few "John Wycliffe"s around this time, and there are doubts that the one who went to Merton College in Oxford in 1346 was the same one who was master of Balliol (a far more liberal-minded college) in 1360, who was given a position in the parish of Fillingham. His time at Oxford might have overlapped that of William of Ockham; it is certain that the Wycliffe in whom we are interested was familiar with and influenced by Ockham's writings.

His running of Fillingham (and a succession of parishes) did not prevent him from living at Oxford and participating in the college as an instructor and a scholar. He became known and respected as a theologian, and received his doctorate in theology in 1372.

Wycliffe's entrance to politics is presumed to be in 1365, when he advised John of Gaunt (the king's son, but a powerful political figure in the wake of King Edward III's increasing senility) to deny Pope Urban V the 33 years of feudal tribute for which England was in arrears. The tribute had been established by King John, but Wycliffe told Gaunt that the papacy was wealthy enough and did not need or deserve the money. Gaunt and Parliament were all to willing to agree: Edward III had the habit of outspending his income, money was always needed in case a war with France should arise again, and this was the time that the papacy itself was in Avignon, France. Giving money to the pope in France felt like giving money to the enemy against whom you might need to fight a war some day!

By this time, Wycliffe had developed strong opinions opposing the wealth of the church. He was not branded a heretic (yet!). Had he been openly thought of this way, he would hardly have been included in the delegation that attended the peace congress in Bruges in 1374. Bruges had two purposes: establishing reduced hostilities between England and France, and dealing with the papacy's problems in the English church. He seems to have attended purely as a respected theologian whose opinions were academic, not militant. At the time he was still friends with men like the monk John Owtred, who held that St. Peter proved the union of spiritual and temporal power—an idea totally opposite to Wycliffe's thoughts on the subject.

That would change in the next decade. By the time of Wycliffe's death ten years later, he would lose his friends, his positions, and the respect of the papacy and many of his colleagues. He would also start a reform movement, produce a controversial Bible, and influence a reform movement in Bohemia. More tomorrow.

Eclipse in 828

A lunar eclipse was recorded for July 1 in 828 very early in the morning. A second one occurred on Christmas Day, and was recorded thusly in the Anglo-Saxon Chronicle:

In this year the Moon was eclipsed on mid-winter's Mass-night, and the same year King Ecgbert subdued the kingdom of the Mercians and all that was South of the Humber.

Note the lack of panic, such as we expect from Hollywood's portrayal of technologically primitive people experiencing an eclipse. Even if your theory of the heavens were no more sophisticated than perceiving heavenly bodies as balls of light affixed to concentric crystal spheres, you would realize that they could simply overlap at times. The Babylonians and Greeks had figured out the patterns of eclipses centuries earlier than the Anglo-Saxon Chronicle, and Isidore of Seville (c.560-636) in his Etymologies (which was used throughout the Middle Ages the way we would use an encyclopedia) explained

"The moon suffers an eclipse if the shadow of the earth comes between it and the sun" while an eclipse of the sun takes place "when the new moon is in line with the sun and obstructs and obscures it."

While Medieval Europe had Isidore to explain what was happening, however, they did not necessarily have the knowledge of the Babylonians and Greeks to understand why it was happening. The event could still be unnerving. Bishop Eligius of Noyon in the 7th century warned: "When the moon is darkened, no one should dare to utter shouts, because it becomes dark at specific times at God's command." Hrabanus Maurus (c.780-c.856), another encylopedist, tells of a lunar eclipse when some threw spears toward the moon, trying to defend it from its attacker.

Even if the mechanism of eclipses was understood, people might still accept them as a sign of great portent, or as the result of human actions. Bishop Thietmar of Merseburg, referring to an eclipse of 990, wrote "I urge all Christians that they should truly believe that this does not happen on account of some incantations by wicked women, nor by eating, and it cannot be helped by any action in the world."

Oh, and when Astronomy Today tells you that the eclipse of May 5, 840 so frightened King Louis that he "died just afterwards"? Ask to see their sources. Louis died on June 20th at the age of 62, after years of quelling civil wars. I think there are likelier reasons or his death than being afraid of an eclipse.

Changing Time

Since today will have one extra second added to it, I thought it would be a good time to talk about calendar corrections in history. We'll avoid the modern arguments about what actually constitutes a "year" and go back to a simpler time.

Readers of this blog are probably familiar with the pope's work to "fix" the calendar when he realized that the Julian calendar was "off" by several days. Sure, the Julian took into account that a "year" is actually 365 and a quarter days, but it wasn't exactly a quarter-day off, and so adding a day every four years wasn't sufficient to even things out. Every 131 years, the solstices and equinoxes would be off by a day. This was a real problem for the Church, because over the centuries Easter started shifting to summer, rather than spring.

Pope Paul III (1468-1549) saw the problem and gathered several astronomers to develop reforms.* Then Paul III died, five popes came and went, and in 1572 Pope Gregory XIII was elected and found himself faced with a growing problem and several possible solutions. He mulled it over for a few years, and then declared to the world:

• The Leap Day would move to after February 28 (it had been tucked in before February 25).
• The date of Easter would be calculated differently.
• A Leap Year that is divisible by 400 will not have a Leap Day.
• Ten days needed to be omitted from the calendar, to bring it back into alignment with the solstices. Accordingly, in 1582, the day after Thursday, October the 4th, was Friday the 15th.

...and then everything was fine. Except when it isn't, like when we have to add an extra second here or there. (And can you imagine trying to explain to someone 1000 years ago that the year gained about 45 seconds every 10 millenia because the Earth's rotation was slowing?)

The 1582 change gave rise to a slight oddity for historians, because technically, every date prior to October 4th, 1582 is a Julian date, but also has a corresponding Gregorian date that is several days different. How you count it depends on whether you consider the date to be just a label given by those who were there at the time, or a certain number of days prior to the present day. Or its important if you want to declare the anniversary of an event.

Anyway, enjoy your extra second; it will be added just before midnight, so feel free to stay up so you can say you remember the time when a minute was 61 seconds long!

*Copernicus had dedicated his work De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) to Pope Paul III, hoping it would save him from potential hostility for his radical thoughts. Had Paul called, Copernicus probably would have come running to join the team of calendar reformers; alas, he had died in 1542.

Rosemary in England

The fragrant and tasty rosemary (from ros marinus, "dew of the sea") grows natively in the Mediterranean. Perform an Internet search for "rosemary + England + herb" and you'll likely be told that it was brought to England by Queen Philippa of Hainault in 1327, when she married Edward III of England. (Examples are here, here, and here; but don't bother.)

The origin of this story seems to be with the translator of a manuscript found in the library of Trinity College, Cambridge. The manuscript is a poetic treatise sent by Queen Philippa's mother, the Countess of Hainault, about rosemary's many uses. Presumably it was sent with a rosemary plant, and thus the legend of the introduction of rosemary to England was born. The treatise has such useful advice as:

mighteth the boones and causeth goode and gladeth and lighteth all men that use it. The leves layde under the heade whanne a man slepes, it doth away evell spirites and suffereth not to dreeme fowle dremes ne to be afeade. But he must be out of deedely synne for it is an holy tree.

Strengthens the bones and causes good, and gladdens and lightens all men that use it. The leaves, laid under the head when a man sleeps, do away with evil spirits, and will not allow one to dream foul dreams or be afraid. But he must not be in a state of sin, for it is a holy tree.

So was it known in England before the 14th century?

The British Library has a manuscript (Royal 12, D xvii) known colloquially as "Bald's Leechbook,"* a ninth-century medical text written in Old English. Rosemary is mentioned in a number of remedies, for fever, horses leprosy, and toothache (always mixed with multiple other substances). It is highly likely that the Saxons found rosemary growing all over England because of its introduction by the Romans centuries earlier.

*Bald's Leechbook deserves its own entry or three. [Update: here it is.]

Nicholas of Cusa: Ecumenist

After the Fall of Constantinople in 1453 to the Turks, Nicholas of Cusa (c.1400-1464) wrote De pace fidei (On the Peace of Faith), in which he envisioned a conference in Heaven of representatives of all religions, including Islam and Hussites (the followers of Jan Hus were one of the first Christian Protestant movements, over a century before Luther).

The imaginary conference concluded that it was possible to have a single unified religion, even if it manifests in many different versions with separate practices. After all, the Roman Catholic Church had co-existed with the Eastern Church for centuries; the Eastern Church may not have recognized the authority of the Pope over the East, but the East and West did consider themselves two parts of the same faith.

Nicholas clearly prefers and exalts Christianity, but is willing to find accord with others. He had written Cribratio Alchorani (Sifting the Koran), which acknowledges that Islam and Judaism still possess seeds of the truth. Let me be clear: Nicholas doesn't treat Islam or Judaism as equals with Christianity—in 1451 he had used his authority as a bishop to require Jews in Arnhem to wear badges, and he had imposed other restrictions on Jews that were later lifted by Pope Nicholas V. The fact, however, that a well-known Catholic prelate and respected theologian could write on and publish such tolerant ideas was remarkable for the time.

Reasoning Wrong

Nicholas of Cusa (c.1400-1464) believed in using reason to determine how the universe worked. He did not exactly take a "scientific" approach: he argued from his understanding of metaphysics and, in some cases, numerology. His guesses, however, were better than some early scholars' observations.

Because he could not accept that God was finite, and since God is not separate from the entirety of the universe, he argued that the universe must by necessity be infinite. Also, because God must provide the center for His own totality, the Earth cannot be at the center of the universe—that would mean Earth was the center of God. Not being at the center of the universe, the Earth cannot be immovable, and it, along with the Sun, must be in motion just like every other observable heavenly body. This idea influenced Giordano Bruno.

Again, denying perfection for anything but God, he would not accept planetary orbits as perfectly circular, paving the way for Kepler (who referred to Nicholas as "divinely inspired") to design elliptical orbits in his planetary theory.

Cusa's thoughts on what we now call infinitesimals in his De Circuli Quadratura (On Squaring the Circle) helped Kepler out when trying to calculate the area of a circle, by picturing it as an infinite series of triangles. Cusa's reasoning for this was that the circle encompassed all other forms. Cusa's and Kepler's work was later important to  Leibniz' Law of Continuity.

Tomorrow: his views on bringing religions together.

Nicholas of Cusa

American History has a charming anecdote that the head of the US Patent Office once declared there was nothing left to invent. The background for this fable is explained here. Someone in 2010 said that we create as much data in 2 days as in all of 2003. Our ability to find and learn new things looks like it will never match the things there are to learn.

With the amount of knowledge being gained rapidly accelerating, why don't we know everything yet? Will we know everything?

Nicholas of Cusa (c.1400-1464) had an opinion on this. He outlined the problem in the opening remarks of his De Docta Ignorantia (On Learned Ignorance):

It so far surpasses human reason, however, to know the precision of the combinations in material things and how exactly the known has to be adapted to the unknown that Socrates thought he knew nothing save his own ignorance, whilst Solomon, the Wise, affirmed that in all things there are difficulties which beggar explanation in words;

He argued, however, that every living creature is

endowed with suitable faculties and activities; ... there is in them a discernment that is natural and in keeping with the purpose of their knowledge, which ensures their natural inclination serving its purpose and being able to reach its fulfillment.

If that is true, he says, then limits to our ability to know things must be built-in by our Creator for a purpose. And that purpose is that, at the end of our reasoning, when reason fails, we must turn to faith for the ultimate answers.

For this, Nicholas has been declared an anti-intellectual by at least one prominent modern scholar. But this misses his point: until we reach the limits of what we can figure out, we must travel as far as we can with reason. Just how far Nicholas of Cusa let his reason take him (and in ways that were appreciated by men like Bruno, Copernicus, Galileo and Kepler) I will explore this week.

Gervase and the Moon

Yesterday I mentioned Gervase of Canterbury and his fairly unremarkable life. What follows is the reason he makes an appearance in footnotes in astronomical texts.

Among his other writing duties and pleasures, Gervase also kept the monastery's chronicles, and in 1178 he recorded something interesting:

This year on the 18th of June,[*] when the Moon, a slim crescent, first became visible, a marvelous phenomenon was seen by several men who were watching it. Suddenly, the upper horn of the crescent was split in two. From the mid point of the division, a flaming torch sprang up, spewing out over a considerable distance fire, hot coals and sparks. The body of the Moon which was below, writhed like a wounded snake. This happened a dozen times or more, and when the Moon returned to normal, the whole crescent took on a blackish appearance.

Scholars and astronomers have puzzled over this. Astronomer Jack Hartung in the September 1976 issue of the journal Meteoritics proposed that they had witnessed a meteor strike that created the lunar crater "Giordano Bruno." Recent photos by Apollo made it, in his opinion, a candidate for a young crater only 800 years old. Hartung had his critics, but without new data on the crater, the verdict could rightly claim to be "up in the air." Until years later a student named Paul Withers in Weekly Scientist pointed out an obvious flaw. An impact great enough to create the 14-mile wide Giordano Bruno would have thrown "10 million tons" of debris off the lunar surface; the ejecta in short order would have created unbelievably spectacular meteor showers in Earth's atmosphere. These meteor showers were not noted by monks in England or any other of the sky-gazing cultures that dotted the globe at the time.

So what did the monks see? His guess is that they were looking in the right place at the right time to observe a meteor entering Earth's upper atmosphere between their line of sight and the horns of the crescent moon.

For a modern astrophysicist's view on Gervase' chronicle, see Brian Koberlein's Google + post for today, June 25th, called "Mining for Science."


*N.B. The Proleptic Gregorian Calendar (used for dates prior to 1582 because of a necessary correction) turns this date into June 25th, meaning today is the 834th anniversary of the monks' observation.

Gervase of Canterbury

Gervase of Canterbury (c.1141-c.1210) was a monk of Christ Church in Canterbury. He was ordained on February 16, 1163 by Archbishop of Canterbury Thomas Becket (who would be assassinated in 1170, canonized by Alexander III a few years later, and become the focus of the most famous shrine in England).

Gervase had a fairly undistinguished career as a monk, and his "importance" for us is in his connection to other people and events. He was involved in the dispute between the monks of Christ Church and Archbishop of Canterbury Baldwin of Forde. Baldwin disapproved of the luxury in which the monks of Christ Church lived, derived from the donations made by pilgrims to the shrine of St. Thomas Becket. At one point, Baldwin had the entire monastery confined under house arrest for a year and a half. Gervase was one of the monks sent to inform Baldwin that they were making an appeal to the pope. Ultimately, the monks were given their freedom and normalcy restored (except that Baldwin appointed Roger Norris, a pretty ineffective administrator, as their prior).

For a brief time Gervase held the position of sacristan (the person who takes care of the church and its contents), working for the Archbishop Hubert Walter.

...and that's about it for Gervase, except for one little thing that has intrigued historians and astronomers for centuries. Gervase kept records and wrote books, such as a history of the Archbishops of Canterbury and his Mappa Mundi, which lists bishoprics and ecclesiastical houses in England, Wales and Scotland. He was also the chronicler of his monastery, and on the night of June 18th, 1178,* he recorded something curious and previously unseen.

...but what the event was, and how June the 25th is actually the anniversary of the event on the 18th, I'll save for tomorrow.

*The same year this was happening in Italy, as mentioned on the June 20th post.

Mappa Mundi

Approximately 1100 mappae mundi (maps of the world) have survived from the Middle Ages; about 200 are separate maps; the rest are in books.

Maps of the world were obviously limited by knowledge of geography. This did not deter medieval cartographers, however, since maps existed for along time not as guides for travelers, but as diagrams of the layout of God's creation. Minutiae weren't as important as portraying the overall plan, or showing a particular feature. For instance, Gervase of Canterbury's Mappa Mundi was drawn up specifically to show the bishopric s and ecllesiastical foundations of England, Scotland and Wales.

One of the most common of the map designs was the T-O design, called that by modern scholars because it resembled those letters. The "T" was the division of the major landmasses with the enormous Asia topping Europe and Africa; "O" was the encircling Ocean.

Note that Asia is on top. When choosing proper positioning for the arrangements of the continents, the direction of the rising sun seemed to be a logical place to begin. East is therefore placed at the top of the maps, and the arrangement of things in their proper place on a map therefore was called "orienting."*

Cicero's Dream of Scipio (in which a vision of the world is viewed in detail) was very popular in the Middle Ages for what it had to say about the world and the divine. Macrobius' (5th century CE) Commentary on it was how many readers became familiar with it. Many copies of the Commentary include mappa mundi of the type therefore called Macrobian. The Dream includes a description of the various zones, cold to temperate to hot to temperate to cold. Only the temperate zones were considered habitable.

Fourteen manuscripts of Beatus of Liébana's (c.730-800) popular Commentary on the Apocalypse of St. John include the quadripartite-style map that squeezes the Antipodes into the extreme south.

The most famous and most detailed maps provide the most variety and data and start to approach the realism and usefulness of modern cartography. The symbolic value of the mappae mundi began to be replaced by the need for accurate information to aid in travel and, especially, navigation on the seas. The new "Portolan Charts" became far more valuable to have and reproduce, and the number of mappa mundi were produced less.

If you would like to see some maps from across the ages, a good start is the Imaginary Museum.

*An extra tidbit: "orient" comes to Middle English from Latin via French and the verb oriri, "to rise"; once in English it starts being used for the direction itself in which the sun rises.

The Antipodes

As the unknown becomes close and familiar, imagination must seek new realms further away. Modern fiction doesn't write about alien life on the Moon or Mars or Venus, since we now "know" those spheres. In the Middle Ages, it was assumed that fantastical lands and creatures existed "over there." As far lands such as Africa, for instance, began to be explored and found mundane, the fantastical was mentally placed in a more distant spot.

The Antipodes (literally "opposite feet": the place on the globe directly opposite to where you are standing)* fascinated the Middle Ages for both philosophical and geographical reasons. On the one hand, the idea had come to them from the Classical World, and so was difficult to dismiss. This was the place that held creatures out of legend: Cyclopes, dog-headed men, Sciopods whose single large foot could be used as an umbrella when they lay on their backs, Blemmyae with faces on their torsos. On the other hand, the Medieval idea of symmetry demanded that there be lands to the far south, balancing the known lands in the north. Especially as the idea of earth's roundness took shape, Africa wasn't enough to satisfactorily balance Europe and Asia.

The Antipodes were also a natural extension of the theory of "zones." Since it became very cold up north, and hotter as you went south, it was assumed that the temperate zone enjoyed by most of Europe had a counterpart below the equator which was equally inhabitable. Below that, of course would be the area that is opposite the Arctic: the Anti-Arctic, or Antarctic.

The term was first used by Plato in his Timaeus. It was first used in English in 1398 in John of Trevisa's translation of Bartholomaeus Anglicus' De Proprietatibus Rerum (On the Order of Things):

Yonde in Ethiopia ben the Antipodes, men that haue theyr fete ayenst our fete.
(Yonder in Ethiopia are the Antipodes, men that have their fete against our feet.)

Some in the Middle Ages used the image of upside-down men as a reason to reject the Earth as a globe and opt for a flat Earth. Plato had addressed this himself, however, in an assumption of orientation that he does not call gravity but that works the same way:

For if there were any solid body in equipoise at the centre of the universe, there would be nothing to draw it to this extreme rather than to that, for they are all perfectly similar; and if a person were to go round the world in a circle, he would often, when standing at the antipodes of his former position, speak of the same point as above and below; for, as I was saying just now, to speak of the whole which is in the form of a globe as having one part above and another below is not like a sensible man.

But sensible men apparently did not read the Timaeus, or never grasped the concept of "up" and "down" being relative to where you were standing. A universally accepted map of the world was unknown; maps of the world typically took one of four forms, which we will look at tomorrow.

*Have fun finding your antipodal point here.

Summer Solstice

The first full day of summer seems to be the appropriate place for this:

Sumer is icumen in,
Lhude sing cuccu!
Groweþ sed and bloweþ med
And springþ þe wde nu,
Sing cuccu!
Awe bleteþ after lomb,
Lhouþ after calue cu.
Bulluc sterteþ, bucke uerteþ,
Murie sing cuccu!
Cuccu, cuccu, wel singes þu cuccu;
Ne swik þu nauer nu.
Sing cuccu nu. Sing cuccu.
Sing cuccu. Sing cuccu nu!

Summer has come in;
Loudly sing, cuckoo!
Groweth seed and bloweth meadow
And the wood springeth anew,
Sing, cuckoo!
Ewe bleateth after lamb;
Cow loweth after calf.
The bullock starts, the buck farts,*
Merrily sing, cuckoo!
Cuckoo, cuckoo, sing well cuckoo;
Nor never now stop.
Sing cuckoo now. Sing cuckoo.
Sing cuckoo. Sing cuckoo now!

*There is disagreement on the meaning of "uerteth"; is it for "verteth" meaning "turns" (the buck is looking around for a doe?) or does the "v" sound indicate the fricative "f" for "ferteth" meaning "farts" (Middle English ferten = "to fart"; indicating...the richer diet of spring means life is being generated?). I have chosen "farts" simply because it rhymes with "starts" and gives me a chance to include this footnote. Happy Summer!

The Pisan Mistakes

According to legend, a rich widow named Berta di Bernardo left 60 coins in her will for the construction of a campanile, a bell tower, for St. Mary's Cathedral in Pisa. A 55-meter tower was planned, belvedere style so that people could walk up the outside and enjoy the view. Ground was broken August 9, 1173.

The architect/builder is unknown. Either he was simply undistinguished, or he was careful to keep his name out of the public eye once the project was begun in order to avoid the inevitable ridicule. Pisa was built at the junction of two rivers, the Arno and the (now dried and gone) Auser; when the builder dug a 3-meter deep hole for the foundation, he found only river clay and sand. This lack of bedrock did not deter him. He proceeded to build what was designed to be a 14,000-ton structure on top of this soft foundation; by the time he got to the third level in 1178, it had already started to list to one side.

They had no way to change the ground on which it stood, and they didn't want to give up the project, so they built the next floors with one wall higher than the other, so that the upper floors wouldn't slant.

A series of financial problems and wars with neighboring city-states (mostly Florence, but Pisa also lost a major conflict with Genoa) meant the campanile wasn't finished until 1319. Nothing they did could fix the increasing list. But then, nothing they did would have. Adding the bells? More leaning. Deciding to add an impressive 3.5 ton additional bell? More leaning. Even so, the tower was only leaning by five degrees in 1837, when Alessandro della Gherardesca decided to turn an embarrassment into a tourist attraction by exposing the famous flawed foundation. He dug around the base...below the water table. The space flooded, the clay and sand softened more, and over the course of a few days, the tower leaned another meter!

In 1934, the idea arose to drill holes in the foundation and force grout into them. It looked good on paper; in reality, it increased the tilt. Tinkering in 1966 and 1985 just made it worse, and the tower was closed to the public in 1990.

Years later, the combination of a steel corset around the base, concrete, and counterweights were supposed to be the ultimate fix. They weren't, although they did almost cause the whole tower to break apart from stress. Finally, someone decided to go to the root of the problem. They dug away at the foundation on the other side of the tower, hoping it would lean back the way it had come. A little over 800 years of tinkering since the problem first appeared, and not only was the tilt reduced, but the tower was stabilized and re-opened to the public. Once again, tourists can climb the tower and take photographs looking out over Pisa, rather than just ground-based pictures of them appearing to hold up the tower with their hands.

Medieval Tablets

Herman of Tournai (1095–1147), an abbot of St. Martin of Tournai (in Belgium) wrote an account called The restoration of the Monastery of Saint Martin of Tournai. In the prologue, he comments "I even wrote down a certain amount on tablets." He would have been referring to a wax tablet, which were used since the Roman Empire and became increasingly common in the Middle Ages.


A shallow wooden or ivory frame filled with soft wax could be written on with a stylus; the other end of the stylus was a flattened blade shape that could be used to smooth out the wax for re-use. The beeswax would be mixed with plant oils and/or carbon to create a more legible surface. Tablets were often not simply one piece; They could be turned into leather-laced "booklets" where the outer tablets held wax on the inside, and inner "pages" would have wax on both sides.


Wax tablets were great for business records. A hospital in Enns, Austria used multiple-page wax tablets (that still exist) to track some financial records. Payables due would be printed on parchment and stuck to the left side; money received would be written on the right side in wax and added up. The impression would store indefinitely—so long as you didn't let it get hot.


Tablets were also ideal for transactions that did not need to be kept long-term. The impression could last for a week or month or season, and then warmed up and smoothed over for the next set of transactions off the boat.


Here's an extensive directory of links to pictures of tablets from across the centuries.

The Church & Marriage

On April 19, 1213, Pope Innocent III declared via papal bull that a great council would be held; the Fourth Lateran Council started November 11, 1215. One of the reasons Innocent felt the need for reform was the poor performance of the Crusades: the Third had been disappointing in its result and the Fourth a downright disaster in its execution. Organizing the Fifth Crusade was one of the purposes of the Council; Innocent produced 70 additional decrees which were generally accepted with little argument.

One change created by the Fourth Lateran was in marriage. Prior to 1215, marriage was simply a legal contract between two parties, not a sacrament.* Innocent made it a sacrament, making marriage a much more important bond and presided over by the Church.

He next declared that marriages could not be clandestine: they must be proclaimed publicly ahead of time so that anyone who knows a legitimate impediment against the marriage has a chance to make it known. He warns, however, that lying about such impediments will bring the wrath of the church down on you.

Was this a power grab? An attempt to assert the church's control over political unions? Innocent knew there was bound to be some opposition to "re-defining marriage"; he prefaced his marriage decrees with this:

It should not be judged reprehensible if human decrees are sometimes changed according to changing circumstances, especially when urgent necessity or evident advantage demands it, since God himself changed in the new Testament some of the things which he had commanded in the old Testament.

Innocent was pope from January 1198-July 1216, during which he made many changes, some of which are still with us.

*Pre-1215, there were only 5 sacraments: Baptism, Communion, Confirmation, Holy Orders, Last Rites; 1215 established Marriage and the practice of individual Penance at least once per year.

God as Mother

The Leadership Conference of Women Religious is making news, and my desire to make this blog not just interesting and varied but also relevant prompts me to talk about Julian of Norwich.

Mystics—people who attain knowledge of the divine not by rational study but by a direct connection or intuition, often during a state of ecstasy—are known in all faiths and all eras.

Julian of Norwich was an anchoress (a female anchorite, a hermit; she lived a life of religious seclusion) who had a series of mystic visions of Jesus in 1373 (she was about 31 years old) while on what was thought to be her deathbed. She recovered on May 13, and wrote down a short version of the visions. In about 1393 she wrote a much longer version, Sixteen Revelations of Divine Love, possibly the first book written in English by a woman.

One of her most controversial habits is to refer to God and Christ as Mother as well as Father. One such passage:

And thus I saw that God rejoiceth that He is our Father, and God rejoiceth that He is our Mother, and God rejoiceth that He is our Very Spouse and our soul is His loved Wife.
...
God is Very Father and Very Mother of Nature...

Church authorities at the time did not challenge her. This cannot be because she wrote in obscurity: there are plenty of contemporary references to her, and she was operating in Norwich, the second most populated city in England. Either the church did not consider her ideas likely to become influential, or they were not shocked by them. After all, she did not say God was solely mother; she simply allowed for feminine qualities as well as masculine. Perhaps this all-inclusive approach was sufficiently non-threatening to be accepted as non-heretical. Perhaps the Middle Ages was willing to embrace the importance of the feminine along with the masculine.

Tide Goes In, Tide Goes Out

The Classical World and the Middle Ages wrestled with the cause of the tides for centuries. Although one early scholar (Alpetragius, who flourished in the late 1100s) felt it was caused by some general motion of the world/celestial spheres that ran from east to west, most others (such as Bede and Gerald of Wales) felt it had a stronger connection to the movement of the Moon.
Alpetragius died in 1204, and his theory on the motion that caused the tides was translated into Latin by Michael Scot. This brought it to the attention of Robert Grosseteste (c.1175-1235), who had an explanation for the tides that relied on his theories of light. (The following is from the Questio de fluxu et refluxu maris, attributed to Grosseteste, although that attribution is disputed.)

Remember that there was no working theory of gravity yet; just a feeling that substances could be heavier or lighter depending upon their composition and gravitate (see? in this enlightened age, the concept of gravity pervades even our language) toward like substances: solids fall to earth; liquid (containing more of the element of water) flows to a lower spot to find its kind; fire yearns upward through air, because fire is even "lighter" than air.

For Grosseteste, light imparted force. Rays of light could carry with them the power to generate heat, for instance (see his theory on the sun). He postulated that, when the Moon rose above the horizon, its rays impressed against the waters and pushed them ahead of it, toward the west. This was not as simple and direct as a physical object pushing against water, and so water didn't rush to the shore as soon as the Moon rose. The rays of the Moon started pushing against the sea closest to it, pushing that water toward the observer. When the Moon was overhead, its rays had pushed as much water as it could at that time. Once the Moon passed the zenith and was over land, then the waters started to recede. The Moon then passes west and under the earth, at that point causing (somehow) the tides again.

Grosseteste admits that we don't know everything about this process, and my summary is a radical simplification of his detailed analysis. He notes the changes in tides as the Moon changes its declination, and theorizes that the Sun also "helps" the Moon in some manner.

Magna Carta

The "Great Charter" was signed on June 10, 1215 by King John.

After the Norman Invasion of 1066, the kings of England started to rule more as the monarchs we think of today, abandoning the English custom of a council of wise men, the witenagemot, that had aided kings for centuries. Under strong and charismatic individuals such as Henry II (who ruled from 1154 until 1189), this system may have worked, but King John was not like Henry II. He was called "Bad" King John because he taxed people so heavily. He was called "Lackland" (in Old French, Johan Sanz Terre) because he lost the Duchy of Normandy to King Philip II of France. For these and other reasons, he lost the support of his barons.

The barons decided they needed to return the kingdom's governance to a system that allowed them more input. To that end, they conferred and agreed to draw up a great charter, which was drafted by the Archbishop of Canterbury, Stephen Langton. Although Langton may not have been as affected by John's whims as the barons, he had been the cause of a dispute between John and Pope Innocent III, which had resulted in John's brief excommunication. Langton definitely saw the need to curb John's ability to get himself and England into trouble.

When John decided to tax the barons themselves in order to mount a war to regain lost provinces on the continent, the barons had had enough. The barons and Langton produced a document called the "Articles of the Barons" in January of 1215, which John rejected. The barons then armed themselves and marched to London, occupying it in May. They confronted John at Windsor Castle, and he agreed to a meeting at a place called Runnymede.

Some items established by Magna Carta:

• The Church was free to rule itself, especially in the appointment of bishops.
• No new taxes, except with the consent of the Great Council, or Parliament
• Weights and Measures were to be made uniform throughout the realm
• Everyone had the right to due process

On June 15th (797 years ago today), the Barons reciprocated by renewing their Oath of Fealty to King John.

Of course, John had no intention of being bound by the restrictions of the Magna Carta, but that's another story.

1066: What Really Happened

When Edward the Confessor died, he supposedly made a deathbed statement committing his kingdom into the care of Harold Godwinson. As the most powerful man in England after the king, he was a natural choice. Whether Edward actually made that statement or not, the witenagemot, the group of wise men who counseled the king, approved Harold as king. He was crowned on the same day Edward was buried.

When word reached Duke William of Normandy across the English Channel, the response was understandably extreme: William not only claimed that Edward had named him his heir years earlier, but supposedly Harold himself had sworn on a saint's relics two years earlier to recognize William as king of England after Edward. (More detail can be found in yesterday's post.)

William was incensed. The report that Harold had broken a vow made on holy relics was so significant that it enabled William to procure the pope's blessing to depose Harold and take the throne. (Of course, William might have had help: Pope Alexander II was a former student of Lanfranc, who had been first an enemy and then a supporter of William and was not above exercising his influence on his former pupils.) The fact that William's army marched under a papal banner and blessing would have had a demoralizing effect on Harold's forces.

Worse than the psychological effect, however, would have been physical exhaustion. The stories we hear in our grade-school history books about 1066 leave out a third party: Harald Hardrada.

Harald Hardrada, King of Denmark and Norway, also believed he had a claim to England, since Danes had ruled it in times past. Harald landed in the north of England in September of 1066 with 300 longships, 15,000 men, and King Harold's brother, Tostig. On September 20 he defeated the first English forces he encountered. King Harold, however, met Harald five days later at the Battle of Stamford Bridge. Once Harold's forces managed to cross the bridge, he killed Harald and Tostig and defeated the army so soundly that only 24 ships survived to flee back to Denmark. This was not an easy battle, however, and the standoff at Stamford Bridge alone supposedly cost Harold about 20 of his best warriors and closest companions.

...and while Harold's army was recovering from their hard-won battle, the message arrived that William's fleet had arrived at Hastings, 300 miles away. The army (not recovered from their battle) had to march quickly south and meet William's fresh forces who had had plenty of time to prepare their defenses and pick the battle site. Who knows what would have happened if Harold's forces had been able to meet William's while at full strength? The years following the Battle of Hastings in 1066 are well-known, but history books too often leave out the crucial three weeks prior to the battle, when Harold and his English army performed herculean tasks to defend their shores.

Who Will Rule?

In 1051, when King Edward the Confessor was inviting more friendly Normans to join him in England, Duke William of Normandy visited. According to records made after 1066 but before William's death in 1087, William reported that Edward (who was celibate and would have no heirs of his own) told William that William would be his heir to the throne of England.

In 1064 (two years before Edward the Confessor's death), Harold Godwinson (the most powerful lord in England after the king; his sister was married to Edward) was shipwrecked off the coast of Normandy and held captive by Count Guy of Ponthieu.* Duke William of Normandy told Guy to release him; this was done, and Harold was returned to England, but only after swearing on holy relics that he would recognize William as his king in the future. (This is according to reports written long after the fact by William's chroniclers.)

When Edward died in 1066, Harold claimed that Edward had made a deathbed pronouncement, naming Harold his heir.

There was also a third claimant to the throne, although the least convincing. King Harald Hardrada of Norway and Denmark believed that he was the proper heir, because Danes had conquered England so many times in the past. A tenuous claim, but strengthened by the fact that he was supported by Tostig, the brother of Harold Godwinson! (Ahh, the days when sibling rivalry had higher stakes!)

The problem with all these claims?

In primarily Anglo-Saxon England, the next king was chosen by the witenagemot, the meeting of wise men. Kings might name a successor, but the Witan was needed to approve a ruler.

So who pressed their claim?

All of them.

I'll tell you the unhappy (for Harold) result tomorrow.

*Note: This is about the only reason why anyone studying history cares about Guy of Ponthieu. Feel free to forget the name.

Edward the Confessor

Edward's life was a series of contrasts.

Son of an English king (Ethelred The Unready), he nevertheless spent much of his life in Normandy, making Norman French friends.

Although so pious that he was called "The Confessor," when he became king in 1042 he ruthlessly deprived his mother of all her estates because he felt she had neglected him as a child.

Although he married Edith in 1045, he had taken a vow of celibacy that meant he would produce no heir. (What Edith thought of this is unknown.)

Although his father-in-law was Godwin of Wessex, one of his most powerful retainers, he and Godwin were frequently at odds. When Edward asked Godwin to punish some of his subjects who had hassled the king's Norman friends, Godwin refused and raised an army to fight Edward. Unfortunately for Godwin, none of the other great lords wanted to join him, so Godwin found himself losing and had to choose exile for himself.

Although Edward should have learned his lesson regarding Norman vs. Anglo-Saxon friction, Edward increased the number of Norman councilors. The Anglo-Saxon population disliked this so much that they supported Godwin when an invasion by his two sons, Harold and Tostig, took place in 1052. Godwin was allowed to return. Godwin forced Edward to send the Normans away.

Although he had unhappy dealings with Godwin's family, when Godwin died in 1053, Edward named Godwin's son Harold the heir of Edward.

Although he named Harold his heir, William of Normandy claimed that Edward had named William his heir in 1051. When Edward died in 1066, the stage was set for conflict.
