A Papal Secretary Makes His Mark

Poggio's notes on monument [link]

Many months ago this post mentioned a time when there were three popes at once, who were finally removed and replaced with a fourth. The truth is that there was a two-year gap before the Cardinals settled on a single pope. During this time, what did all the servants and staff of the Vatican do with themselves? One of them went searching for manuscripts from the past and made of them a gift to the future.

His name was Gian Francesco Poggio (later called "Bracciolini," and he was born in Tuscany on 11 February, 1380, but grew up in Florence where his father took him to be educated. It was soon clear that he had a great talent: his penmanship. In an age when all documents were created by hand, penmanship was prized. He was put in school to become a notary.

Notaries were authorized to oversee certain legal documents and transactions. At 21 he was a member of the Notaries Guild in Florence. Two years later, he was working for a cardinal, and a few months after that, for the Vatican itself. With his penmanship skills and knowledge of proper document organization and preparation, he quickly moved up through all the ranks of official Vatican scriptors, working under four popes.

Then came 1414 and the Council of Constance that got rid of all three warring popes, beginning a two-year gap in the need for secretaries who produced official documents. Poggio decided to travel. He visited the German spa at Baden, abbeys in Switzerland and Swabia, St. Gall and many others. He brought to light sole copies of important works by classical authors that might have otherwise disintegrated without being copied.

At Gall he found unique documents by Cicero, Quintilian, Statius, Gaius Valerius Flaccus, and more. Cicero's complete Orations were recovered at Cluny. The only known copy of the encyclopedic De Rerum Natura ["On the Nature of Things"] by Lucretius was recovered from a German monastery (probably Fulda). One Harvard scholar credits Lucretius' 7400-line poem on the world with kickstarting the Renaissance.

He returned to his Vatican duties, being named Apostolicus Secretarius, the papal secretary, under the newly elected Pope Martin V. He traveled a great deal still, moving around when the pope did and on re-assignments (he spent five years in England, which he hated), looking for manuscripts that needed bringing into the light. He worked under several more popes until he finally retired to a villa that he had built with the money from the sale of a manuscript by Livy. In 1453,* he was offered the position of Chancellor of the Florentine Republic by Cosimo de Medici. He fulfilled his duties there until his death in 1459.

*Coincidentally, he retired from a career created by his excellent hand-writing of documents at the same time Gutenberg was perfecting movable type and ushering in an era of mass-produced books.

St. Scholastica, Weather Witch

Today is her feast day, as well as the anniversary of the St. Scholastica's Day Riot in Oxford. She was the twin sister of Saint Benedict, but made quite the name for herself. Like her brother, most of what we know about her came from the Dialogues of Pope Gregory I (mentioned here).

She was born in Italy (c.480 - 10 February 542), and devoted herself to God in her youth. She founded a monastery for women about five miles from Monte Cassino, where her more famous brother had a community.

The communities were "gender-specific," so when the siblings wanted to meet they chose a neutral location. During one of these visits, she wanted her brother to stay overnight, but he was loath to spend a night away from his monastery. Chapter 33 of the Dialogues tells the tale of what happened next:

At that time, the sky was so clear that no cloud was to be seen. The Nun, hearing this denial of her brother, joined her hands together, laid them on the table, bowed her head on her hands, and prayed to almighty God. 

Lifting her head from the table, there fell suddenly such a tempest of lightning and thundering, and such abundance of rain, that neither venerable Benedict, nor his monks that were with him, could put their heads out of doors. The holy Nun, having rested her head on her hands, poured forth such a flood of tears on the table, that she transformed the clear air to a watery sky. 

After the end of her devotions, that storm of rain followed; her prayer and the rain so met together, that as she lifted up her head from the table, the thunder began.  So it was that in one and the very same instant that she lifted up her head, she brought down the rain.

The man of God, seeing that he could not, in the midst of such thunder and lightning and great abundance of rain return to his Abbey, began to be heavy and to complain to his sister, saying: "God forgive you, what have you done?" She answered him, "I desired you to stay, and you would not hear me; I have desired it of our good Lord, and he has granted my petition. Therefore if you can now depart, in God's name return to your monastery, and leave me here alone." [link]

The next day he departed; three days later she died. Benedict had her body brought to Monte Cassino and laid in his own tomb.

Scholastica is the patron saint of nuns, and is invoked during storms.

War of the Eight Saints

Pope Gregory XI arriving in Rome in 1377
Fresco by Giorgio Vasari

Pope Gregory XI wanted land. He was the last pope to reside in Avignon in France rather than in the Vatican in Rome. Even though he enjoyed living in Avignon, he still felt that the pope deserved more land in Italy. He set out to achieve that by expanding the Papal States, territory that belonged to the papacy.

Understandably, the Italian city-states objected to this; if Gregory wanted more land, he was going to have to take it by force. Gregory was fine with that option. He was fighting a battle with Milan, and when that ended in 1375, he had the opportunity to send his army against Florence, which held lands that would have been ideal for Gregory. Thus started the "War of Eight Saints."

The head of Gregory's mercenary army was an Englishman, John Hawkwood. Florence decided they could "buy off" Hawkwood. They offered him (and his army) 130,000 florins to sign a one-year nonaggression pact with Florence. For Hawkwood himself, they offered an annual payment of 600 florins in a five-year contract and a lifetime annual pension of 1200 florins! Hawkwood kept his involvement to the Papal States themselves, avoiding conflict with Florentine territory. Gregory had to use other forces to attack key areas in Italy.

Who were the "Eight Saints" of the war? Their names aren't agreed upon, and they weren't saints. Gregory excommunicated Florence for its opposition, using the phrase otto dei preti ["eight priests"] to refer to specific men whose acts prompted the excommunication.* These eight would have been one (or both) of two groups of eight men: one was appointed to come up with the means of buying off Hawkwood (these men also forced a loan on the clergy of Florence to amass the money needed for Hawkwood); the other was the otto della guerra ["eight men of war"], eight men appointed to manage the war against Gregory.

Gregory ultimately returned to Rome in January 1378. If he wanted to maintain his property in Italy, he was going to have to oversee it personally. In a sense, the Avignon papacy ended by default.

*Florence had an unexpected reaction to excommunication—unexpected to our modern ideas of how devout the Middle Ages were. Someday...

Stones of Magnesia

A perpetual motion machine powered by magnetism,
described by Peter Peregrinus

Magnets/lodestones have fascinated people for at least 25 centuries. We should first clarify the names. The word "lodestone" was first used in the 16th century and refers to the metal ore with magnetic properties. The word "magnet" was coined by the Greeks far earlier and refers to "stones from Magnesia." Magnesia was a region in Thessaly where it was easy to find the magnetic ore.

Aristotle informs us that Thales of Miletus (625 - c.525 BCE) was certain that magnetism, since it caused the rock to move, was a sign that all things—even rocks—were imbued with divine power; essentially, with "soul." Pliny the Elder mentioned a mountain near the Indus River that was a giant magnet. Superstitions about magnets abounded, and it was incorporated into legends. A mid-twelfth century romance about Aeneas claimed that the walls of Carthage had meanest in them that drew and incapacitated the weapons of Aeneas' men.

Bishop of Paris William of Auvergne in 1231-6 used magnetism as an analogy for the motion of the celestial spheres. A generation later, a French scholar named Peter Peregrinus, or Peter of Maricourt, wrote Epistolæ de Magnete ["Letters on the Magnet"] to a friend, explaining the observable properties of magnets. He describes the two poles, attraction and repulsion, and how to make efficient compasses. His work was so thorough that no one bothered to write another work on magnets until 1600, and that person quoted Peter's work.

Fair Rosamund

Fair Rosamund's Well today.

Blenheim Palace is of fairly recent vintage—the early 1700s is "recent" in the context of a blog devoted to the Middle Ages—but the site contains some much older features. A spring on the property fills a well that existed at least as far back as 1166, when royal accounts list a building project designed to enclose the spring, known at the time as Everswell. The name can be accounted for by a local legend that says it never runs dry. Nowadays, it has a different name; from the 16th century on, it has been referred to as "Rosamund's Well."

The Rosamund of the name is Rosamund Clifford, who would have been unknown to history but for an event that pushed her into prominence. Daughter of Walter Clifford, she was born sometime before 1150. Her father's position in government was sufficient that the king had reason to call on him. Sometime in 1163 (according to best guesses), Henry II did just that, stopping at Clifford Castle on the River Wye on his way to deal with a Welsh problem. That is likely where and when he first met Rosamund...

...and when they fell in love.

Henry was married—Eleanor of Aquitaine had divorced the king of France in 1152 and married Henry in 1154—but kings never let marriage stop them. There is much gossip and legend surrounding "Fair Rosamund," but there are a few things we can say for certain. One is that she was a very patient lover: given Henry's campaigns in England and on the continent, between 1163 and her death in 1176, they would not have been able to be in each other's presence for more than 2-3 years total. Stories that she traveled with him can not be substantiated by contemporary evidence.

The likelihood that she bore children for Henry is slim. Later suggestions that his son Geoffrey was hers make no sense, given that she would have had to been pregnant with Geoffrey while she was a baby.*

It is very likely that Henry kept her in Woodstock, which at the time was essentially a hunting lodge about 10 miles north of Oxford. The legend that he built a maze around it to keep her safe is untrue. It is possible, I suppose, that she really did bathe at Rosamund's Well. Blenheim Palace is just west of Woodstock, built on the grounds that once were part of the Woodstock lodge and the enclosed deer park.

She went to live in seclusion among the nuns at a monastery in Godstow in 1176, once her status as the king's mistress became known. She died shortly thereafter, and the king contributed to a family-built  tomb for her at Godstow. In 1191, the bishop of Lincoln found that her tomb, situated in the choir of the church, had become a popular site for locals to leave flowers. Shocked at the veneration given to a mistress, he had her tomb moved outside the monastery. Like so many other sites, it was destroyed by another Henry known for mistresses: Henry VIII's Dissolution of the Monasteries.

*The illegitimacy of Geoffrey is not an invention; Eleanor was not his mother. The chronicler Walter Map (1140 - c.1209) claims Geoffrey's mother was someone named Ykenai.

The Invention of Acne...

A copy of his work [source]

...was a typographical error.

The word "acne" does not come from a classical language root; that is, not in the way we usually derive our modern medical terms. It was described by a Greek physician and then mis-transcribed in a later volume of his work.

Aetius of Amida was a contemporary of Theodoric the Great (454 - 526; mentioned here in connection with Grammar). He was known for the breadth of his learning; his writings show a great knowledge of those who came before him as well as personal skill. He came out of Mesopotamia and learned medicine at Alexandria, known for its medical school.

His famous work was Sixteen Books on Medicine, in which he compiles knowledge from Galen and others of whom we would otherwise have little information: the surgeons Rufus of Ephesus and Leonidas, and the obstetricians and gynecologists Soranus of Ephesus and Philumenus. He is not completely derivative, however. He includes original treatments for eyes, ears, nose and throat, as well as goiter and rabies and others. He also addresses surgical procedures such as for a fistula or tonsilitis.

Although a Christian, he was not immune to the cures that came from non-Christian sources. He relates spells and charms popular in Egypt at the time. Also, in explaining how to help a person suffering from a bone stuck in the throat, he makes the earliest reference to St. Blaise.

As for the condition in which the skin is covered with small eruptions or peaks, he used the Greek word ἀκμή ["acme"; point]. Unfortunately, a scribal error in a later copy turned this into ἀκνή ["acne"]. The popularity of his text made this the common name for the affliction, and so it remains.

An English Mercenary

Funerary monument to Hawkwood

This is the story of how an English soldier of no particular background rose to such prominence that a monument to him sits in Florence, Italy.

John Hawkwood was born about 1320, perhaps in Essex; anecdotes that he apprenticed in London as a tailor before becoming a soldier cannot be substantiated. He served in the Hundred Years War under Edward III. He may have fought at Crécy and Poitiers—again, we cannot be sure of his exact whereabouts during the war—but it is certain that he was no longer employed as a soldier once the Treaty of Brétigny was concluded in 1360.

The life of a soldier suited him, apparently—or he simply had no desire to find passage back to England. He joined one of the mercenary companies that sprang up on the continent. These groups, with no particular allegiance to any nationality and willing to fight for pay against anyone, were called Free Companies. He soon became a member of one called the "Great Company of English and Germans," also known as the White Company. By 1362 he was leading the White Company in battles all over Italy.

Hawkwood was shrewd—some would say "dishonest" or "unethical." Knowing that the White Company was a military force to be reckoned with, he would manipulate the Italian city-states that wanted help. If one offered a contract for the Company's services, he would go to their potential employer's enemy and ask for more money to refuse the initial contract. Sometimes he would be paid simply not to fight for the other side. Florence did this for three months in 1375, when the White Company was employed by Pope Gregory XI to fight Florence.

Despite this behavior, the White Company under Hawkwood gained a reputation for sticking to a contract and not deserting the battle or acting like lawless marauders once a battle was done. Military discipline was one of the commodities you gained when employing the White Company.

Besides being a mercenary, his life dovetailed with other historical events. In 1368, Edward III's son Lionel of Antwerp married Violante Visconti, daughter of then-ruler of Milan, Galeazzo II Visconti. Hawkwood was in attendance and might have met some of the other wedding guests: Geoffrey Chaucer, Petrarch, and the French chronicler Jean Froissart.

John Hawkwood died on 17 March 1394 in Florence. He had lived at that point for several years in peaceful retirement, enjoying the citizenship and pension and villa Florence had given him. Praised for his part in maintaining Florentine independence, he was buried with state honors. Plans for a bronze statue were abandoned due to cost, but 40 years later a monument was created for him by Paolo Uccello, a fresco designed to resemble bronze.

A New Plough

A diagram of the heavy plough with mouldboard

One of the tools that most shaped European culture and improved life in the Middle Ages was a new type of plough. Ploughs drawn by animals to break up the earth were used as far back as 2500 BCE in the Indus Valley; however, those ploughs were simple wooden devices, mostly some form of stick or rake that would scratch the surface of the earth so that seed could be broadcast and covered with dirt. This worked well in the light sandy soils of the Mediterranean and Egypt, but the heavy, wet, clay-laden soils of Europe were another mater. Simple scratch ploughs could not make a dent in those heavy soils, laid down by glacial advance.

Someone devised a plough with two particular features: the coulter and the mouldboard. The coulter (#4 in the diagram) is a vertical cutting blade that cuts a furrow. That isn't enough, however. The mouldboard (#7) is a curved blade that turns a layer of earth over, exposing it and creating a deeper furrow than a scratch plough. Improvements in the smelting and shaping iron by 900 CE made the coulter, the chisel (#5), and the main share (#6) efficient so that the mouldboard could do its job properly.

When dragged through a field the coulter cuts down into the soil and the share cuts horizontally from the previous furrow to the vertical cut. This releases a rectangular strip of sod that is then lifted by the share and carried by the mouldboard up and over, so that the strip of sod (slice of the topsoil) that is being cut lifts and rolls over as the plough moves forward, dropping back to the ground upside down into the furrow and onto the turned soil from the previous run down the field. [link]

A side-effect of this type of plough is that deep furrows are created that help drainage. If excessive water from spring rains can be diverted from fields rather than standing in pools, planting can take place earlier; a longer growing season results, less susceptible to water damage of seedlings.

Around the same time, Europe started experimenting with crop rotation. The practice of using a field every other year for a different purpose was already in place, but three-field crop rotation in which one field is left fallow began to create healthier crops and higher yields at harvest time.

I will not go as far as James Burke* does and say that everything comes from the plough—predictability of future crops, pottery because you need to store grain, writing because you need to make a potter's mark, weaving because you are growing flax, et cetera—but the development of the mouldboard plough literally made a dent in man's difficulties in growing food in European soil. It contributed to population growth and to other advances in technology and civilization.

*The inspiration for this post comes from memories of James Burke's groundbreaking Connections.

Imbolc

The first of February is the date of the Irish quarter-year festival called Imbolc. Imbolc is Old Irish for "in the belly"; it refers to the time of lactation in ewes and lambing, and was the official start of spring.

Imbolc may well be a neolithic tradition [neolithic is from Greek νέος (néos, "new") and λίθος (líthos, "stone") "new stone age"; c.10,200 BCE to c.4500-2000 BCE]. In Leinster, Ireland there is a stone tomb constructed between 3000 and 2500 BCE; the rising sun illuminates the passage into it twice a year, on Imbolc and Samhain.

In the Middle Ages, references to Imbolc are found in Irish literature salting in the 10th century. It became a time to think about the lengthening days and therefore time to think about the plantings ahead. (Conceptually, it was probably a precursor to Groundhog Day.)

The day became connected with St. Brigid, one of the three patron saints of Ireland.* The conflation of the saint with a fertility goddess leant itself to adding a lot of rituals and traditions to the day. Brigid's Crosses were woven from rushes for the occasion by young females, who would carry them while singing a hymn to Brigid.  Brigid would be invited into the home on the eve of Imbolc so that she would bless the house and family members. The ashes of the fire were carefully raked and smoothed that night; in the morning, they would be searched for any disturbance that suggested that Brigid had passed through. Brigid would be called upon to bless livestock for the coming year.

*St. Patrick and St. Columba were the other two.

Cold Weather

Okay, it wasn't that bad

Much of the United States is experiencing lower-than-usual temperatures recently—and the forecast is that there is more to come. The people reading this blog have (I hope) ready access to sources of heat and insulated housing, warm clothing and hot drinks, weather-proof shoes and knit hats. But what of folk centuries ago? How much can we know of the weather of past centuries?

A Chronological Listing of Early Weather Events by James A. Marusek (2010) compiles several sources of weather data from numerous historical records. The detail is praiseworthy. Just a sample from the time of and immediately following the Norman Invasion makes me glad I was not living through those years in Europe.

• 1066 A.D. In England, there was a great frost.
• Also refer to the section 1064 A.D. – 1071 A.D. for information on the drought and famine in Egypt during that timeframe.
• Winter of 1067/1068 A.D. The winter in Europe in the year 1067 was long and intensely cold and many people perished by cold and hunger.
• In 1067, the vine and fruit trees in France were killed [by the extreme cold].
• During 1067-68, in France, the winter between St. Brice to St. Gregory (from 13 November 1067 until 12 March 1068) was extremely severe. The vineyards and forest trees bore no fruit. The mishap brought forth by this and the previous years infertility produced in England such a famine, that the unfortunates were forced to eat dog and horse meat, yes, even to eat human flesh.
• In France, a terrible winter began on 13 November 1067 and lasted until 12 March 1068.
• In England in 1068, there was famine and plague after a severe winter.
• 1069 A.D. The rivers froze in the north of Germany.
• In the year 1069 in Germany, the winter was harsh and long. There was a shortage of wine and fruit because of the extreme cold. The rivers were frozen over. King Henry IV came to the countries of the Saxons and caused such carnage that the area was depopulated.
• In 1069, the Normans desolated England, and in the following year famine spread all over England, “so that man, driven by hungar, ate human, dog and horse flesh;’ some to sustain a miserable life sold themselves for slaves.
• [In England in 1069, there was a great dearth. The peasants of the north, unable any longer to secure dogs and horses to appease their hunger, sold themselves into slavery in order to be fed by their masters. All the land between Durham and York were laid waste, without inhabitants or people to till the soil for nine years. Some of the destitute resorted to cannibalism. A factor that contributed to this hardship was the taxes exacted by the conquerors. Peasants became discouraged, realizing that the fruits of their labor were taken from them as fast as they were earned.]

Abd al-Rahman al-Sufi, Astronomer

MS. Marsh 144, fol. 135v, Bodleian

The contributions of the Muslim world to astronomy are many, and I have only briefly touched on some of them (such as here). There were nine Muslim astronomers in particular who made major contributions. One of them was the Iranian Abd al-Rahman al-Sufi (7 December 903 - 25 May 986). His name indicates that he was a Sufi Muslim, like Rumi.

al-Sufi translated and expanded on the work of the Greeks, especially attempting to reconcile the Greek and Arabic star charts and constellations. In 964 he published Suwar al-Kawakib al-Thabitah, the "Book of Fixed Stars."* In it he gave the latitude and longitude of hundreds of stars for the year 964 from two views: from both the exterior and interior of a celestial globe. The oldest surviving manuscript known is in the Bodleian Library and was created about 1009 by al-Sufi's son. There was no English translation of this book until 2013.

Among the "firsts" that can be credited to al-Sufi's work are the following identifications:

Ursa Major

• "the little cloud" that we call the Andromeda Galaxy.
• the Large Magellanic Cloud*
• the Omicron Velorum star cluster
• a "nebulous object" in Vulpecula, now called "Al Sufi's Cluster"

He also describes the astrolabe and lists a thousand uses of it.

The significance of al-Sufi's work led the astronomical community to name other objects after him, such as a a lunar crater (Azophi) and 12621 Alsufi, a minor plant in the asteroid belt with a period of 2000 days.

*There is an argument that he could not have known of the Magellanic Cloud until the same time as Western European astronomers in the 15th century because of its position in the Southern Hemisphere.

Regarding the Burning of Heretics

In 1401, during the reign of King Henry IV of England, Parliament passed a law known by the phrase, De heretic comburendo ["Regarding the burning of heretics"]. Heresy was always a concern, going back to Pelagius and Arius, but England had a new threat in the Middle Ages, in the form of John Wycliffe, whose attempts at reforming the church and politics did not sit well with those establishments.

True, by 1401 Wycliffe (c.1324-1384) had been dead for years, but his ideas had inspired a movement called Lollardy, and his plan to bring the word of God into the hands of the masses via his English-language Bible ran the risk (according to Church authorities) of leading the faithful astray by giving them the chance to read Scripture without the proper learning to understand its precise meaning. Something had to be done; something proper and legal—after all, England was a country governed by law, not whim.

Hence the De heretic comburendo, which described the Lollards as:

...divers false and perverse people of a certain new sect...they make and write books, they do wickedly instruct and inform people...and commit subversion of the said catholic faith. [link]

The law states further

...and they the same persons and every one of them, after such sentence promulgate shall receive, and them before the people in an high place cause to be burnt, that such punishment may strike fear into the minds of others, ...

This statute stayed on the books in England until 1677.

Charlemagne's Enemy

Much is made of Charlemagne and his unification and christianization of much of Western Europe. What is the other side of the story, however? What of the peoples he attacked and conquered? Charlemagne didn't just proclaim that Christianity was the way to go and let people flock to his standard, begging for conversion. He deliberately set out to convert his part of the world to Christianity.

Widukind gathers support to rebel against Charlemagne

When Charlemagne and the Franks went into Saxon territory and destroyed the irminsul, he provoked the strongest possible reaction. Initially, Charlemagne was successful, even though the Saxons dealt some serious damage, like striking into Frankish territory and destroying property. Charlemagne subdued many of the Saxon tribes and had their leaders attend his court.

One of them refused to attend. The leader of the Saxons (according to the Royal Frankish Annals) who retaliated was called Widukind. (That was probably not his name; it means "Wood Child" and may just be a nickname by which the Franks knew him.) While the other nobles were pledging their faith to Charlemagne at Paderborn, Widukind was off planning insurrection. In 782, while Charlemagne was in Spain, Widukind convinced the Saxon nobles to join him in fighting back against Frankish rule. On his return from Spain, Charlemagne retaliated by capturing and executing rebels—thousands of them.

Despite the Widukind-led opposition, Charlemagne and Franks were eventually victorious. In 785, all resistance was finally crushed. Widukind surrendered on condition that he would not be harmed. His new king was not interested in harming him: he wanted to convert him. After all the years of fighting and trying to preserve his way of life, Widukind was baptized a Christian.

We have very little factual data about Widukind, especially after his conversion. Frankish sources say Charlemagne was his godfather and that Widukind accompanied him on a military campaign.  For later generations of Saxon culture, however, he took on a legendary quality as a symbol of Saxon independence against Charlemagne.

The Irminsul

Remains of an irminsul in Friedrichsgrund

The Royal Frankish Annals have an entry for 772:

The most gracious Lord King Charles then held an assembly at Worms. From Worms he marched first into Saxony. Capturing the castle of Eresburg, he proceeded as far as the Irminsul, destroyed this idol and carried away the gold and silver which he found. 

What was the Irminsul? Rudolf of Fulda, who wrote histories that include the biography of Saint Leoba, defines irminsul in his De miraculis sancti Alexandri ["On the miracles of Saint Alexander"] as "universal column, upholding all things." The irminsul was a pillar made either from a tree trunk or stone and used as a focal point of worship in non-Christian Europe. Records do not exist that would let us zero in on its meaning and purpose; it is simply clear that it was a symbol of paganism and a site of worship.

Attempts to determine the meaning of the name are inconclusive—none are met with universal agreement. The name irminsul, as well as the presence of a Germanic tribe Irminones (mentioned in Tacitus' Germania), suggest that there was a Saxon god named Irmin. Some scholars suggest that Irmin was an epithet of Odin, some say Tyr.

The 12th century Middle High German Kaiserchronik ["Chronicle of Emperors"] uses the term irminsul a few times, such as when discussing Nero:

"He climbed upon an Irminsul
the peasants all bowed before him"

There were likely irminsuls in many locations, constructed of different materials; see the picture above for the remains of one. The best known one was probably that mentioned in the Royal Frankish Annals above, destroyed by Charlemagne. The consequences of that act are worth a look; but that's for tomorrow.

Assembly Line

Detail of the Venetian Arsenal from theCivitates Orbis Terrarum [1572]

When we think of Venice and boats, we think of gondolas being poled through quiet canals. Venice, however, was a powerful presence in the Mediterranean not because of gondolas but because of larger ships that transported people—either for military or religious purposes.*

At some point—possibly in the very early 1100s during the reign of Doge Ordelafo Faliero, or perhaps even earlier—a complex of state-owned shipyards was begun, called the Arsenale di Venezia ["Venetian Arsenal"]. It was designed to provide private shipbuilders with a facility to produce ships for themselves or the state. In 1320, the complex was upgraded to the Nuovo Arsenale ["New Arsenal"] as a place to "build and maintain navy and merchant ships, all in one location." [source]

The Arsenal is probably the first example of large-scale factory work prior to the Industrial Revolution. The complex grew to cover 110 acres, and had a forest dedicated to its lumber needs. The workers, called arsenalotti, numbered in the thousands at the height of production and were said to be able to produce a ship in less than 24 hours. One of their techniques was to build the frame first rather than the hull first. Once the frame was finished, different crews could move in with their pre-fabricated parts for assembly. Rigging, sails, weapons, etc., were prepared by separate teams for the appropriate type of vessel. Dante even mentions this process in Canto xxi of Inferno. These specialists also made improvements in technology, particularly in weaponry. Gunpowder weapons—bombards and handguns—were a particular interest.

Much of the complex is now in ruins, but you can see the Porta Magna, the "Great Gate" that provided the seaward entrance, here.

*Some day I promise to get to my favorite Crusade, the 4th, and how it went horribly wrong.

Æther or...

[I am on a brief vacation, so here is a post from the past. This post first appeared 25 August 2012.]

Speaking of æther...*

In Greek mythology, Æther was the offspring of Erebus (deep shadow) and Nyx (night). Despite springing from dark parents, the word is related to the verb that means "to incinerate";** "æther" was used to refer to pure fresh air, something more pure than ordinary air; in fact, a pure air that was breathed by the gods.

Plato's Timæus (which was very popular for medieval scholars, as I've mentioned before) and his student Aristotle both considered æther crucial to the structure of the universe. Aristotle called it the "fifth element" and described its superiority over earth, air, fire and water because it did not have their limiting properties (hot or cold, wet or dry) and was unchangeable. It was also called quintessence which means "fifth essence/element."

The Greek philosopher Plotinus (c.205-270) taught that there was a supreme "One" that existed prior to all created things, was synonymous with "Good" and "Beauty," and was like a light shining in a void. To the medieval Christian mind, Plotinus was describing God, and therefore was one of those non-Christian philosophers worth listening to. Plotinus said æther was immaterial and could be moved through; he also said there was no such thing as empty space.

Small wonder then that the Middle Ages filled the area above the earthly atmosphere, the space through which the celestial spheres rotated and planets and stars moved, with æther. Æther could not be disproved, and the vacuum of space was as difficult to imagine for the Middle Ages and later as "zero" was for the Romans earlier. The 17th century philosopher Robert Fludd fused Plotinus and Genesis when he explained:

The middle region of the universe, created on the second day, has various names because of the action of the light-stuff as it extended downwards; for, taken by itself, with regard to its own particular material, it is called the Middle Spirit, after the dispersal of darkness: compared to the upper sky, that is, to light-stuff, or mixture of light-stuff and spirit, it is called Ether... [Robert Fludd, The Technical, Physical and Metaphysical History of the Macrocosm and Microcosm, 1617-1624]

The scientific theories were there for all to read and understand.

To be totally honest, the "ether" being tested for in the Michelson-Morley experiment was not conceptually the same æther discussed so extensively in classical and medieval times, but the descent from one to the other clearly runs through the philosophical writings of Western Civilization. Æther was here to stay, until modern technology could eliminate it from our worldview.

Scholar of the Supernatural

[I am on a brief vacation, so here is a post from the past. This post first appeared 23 August 2012.]

In Dante's Inferno, the eighth circle is reserved for sorcerers, astrologers, and false prophets. There the narrator sees Michael Scot. You might think, if someone were so well-known after his death, that we would know more about him. Well, we know a little, but we have some cool stories.

Michael Scot, depicted here tearing up the Scriptures.*

Michael Scot was no doubt born in Scotland, although other locations (like Salerno and Toldeo) have tried to claim him. Dates of 1175-c.1232 seem to work for what little we know of his life. We know that Pope Honorius wrote to Stephen Langton on 16 January 1223, urging him to grant Scot a religious position, and that Honorius himself nominated Scot for Archbishop of Cashel. If Scot was educated sufficiently to be offered these positions, he would not have lived until 1290, which is the date Sir Walter Scott offers for his death. (Scott was confusing Scot with a Sir Michael Scot who lived later.)

Scot turned down the position in Cashel; it looks like he did hold benefices in Italy, however, spending time in Bologna and Palermo before going to Toledo in Spain. It was probably in Spain that he learned Arabic, which helped get him invited to the court of Holy Roman Emperor Frederick II. Besides translating texts for Frederick, he was a court astrologer, saying of the work:

Every astrologer is worthy of praise and honor, since by such a doctrine as astrology he probably knows many secrets of God, and things which few know.

This was not likely to endear him to the Roman Catholic Church.

Although he was known in his lifetime as a brilliant Aristotelian scholar, and Fibonacci's Liber Abaci was dedicated to him, his books on alchemy and astrology and the occult sciences earned him a reputation for magic. A Bronze Age circle of stones in northwest England called "Long Meg and Her Daughters" was supposedly a coven of witches turned to stone by Scot. Other stories have him hosting feasts served by invisible spirits. Boccaccio refers to him in the Decameron as a magician. It is also told (long after the fact) that he predicted he would die from a small stone falling on his head from a great height. He always wore an iron cap to prevent it, but he removed the cap when entering a church one day (more not to stand out than for reverence of God, we are told), and a small stone of the size he predicted fell on his head. He picked up the stone, recognized that his prophecy was coming true, put his affairs in order, and died of the head wound shortly after! His reputation (helped by the dearth of facts) has made him a prime subject for fiction right up to the present day.

Princess, not Empress

[I am on a brief vacation, so here is a post from the past. This post first appeared 2 December 2012.]

When Anna Comnena was born in 1083, she tells us in her history The Alexiad, she was presented with the trappings of a ruler, a "crown and imperial diadem." This might have been appropriate, since she was the only child of the Emperior Alexios I Comnenos. Once her brother John was born in 1087, however, Alexios had another option, and John was proclaimed heir in 1092.

Alexios became ill in 1112, turning the administration of the empire over to his wife, who in turn handed it to Anna's husband, Nikephorus Bryennius. The emperor recovered, however, and lived to fight more battles.  In 1118 he had an attack of rheumatism or gout so severe that he was incapacitated and unable easily to draw breath. Anna was there, offering her medical opinion along with multiple physicians. By placing their hands on the emperor, they detected multiple irregularities in his arteries. After several days of growing inflammation and difficulty breathing and swallowing, he died.

At this point, The Alexiad ends; accounts of what followed come from historical accounts later in the century. John was proclaimed Emperor John II Comnenos. An unsuccessful attempt to murder John took place at the funeral; some modern scholars assume that Anna must have been involved. In fact, we are told by people decades after the fact that Anna attempted to usurp the throne from her brother and place her husband on the throne, so she could reign as empress at his side.

There was an interesting precedent that makes this believable. Nikephorus' father (or grandfather; there is some confusion in the records) had, many years earlier, attempted to take the throne from Emperor Michael VII. The attempt failed, largely because of the efforts of the young man who would grow up to be Emperor Alexios I. In the present case, however, we are told that Nikephorus was not interested in the conspiracy to overthrow John. Anna's response (remember: this was said years later by someone who never knew her) was that "nature had mistaken the two sexes and had endowed Bryennius with the soul of a woman.” The Empress Irene, we are told, also had no interest in overthrowing the rightful ruler, for all that we are told she favored her daughter.

Nikephorus and John actually had a decent working relationship, and accompanied him on a Syrian campaign in 1137. Nikephorus fell ill, however, and returned home early; he died shortly after. Anna, after his death, retired to a convent that her mother had founded, where she began her 15-volume history.

Gravity

Climbing Lucifer in Dante's Inferno

A long time ago (it seems) I touched on gravity and said "there was no working theory of gravity yet; just a feeling that substances could be heavier or lighter." Theories of gravity did not need Newton to become useful to understanding the world.

Still, if the inhabitants of this globe knew it was a globe, they had to come to terms with how things stayed on it. John Mandeville wrote a book of travels in the 14th century in which he addresses this issue:

from what part of the earth that men dwell, either above or beneath, it seemeth always to them that dwell that they go more right than any other folk. And right as it seemeth to us that they be under us, right so it seemeth to them that we be under them. [Mandeville, Voyage and Travels, chapter xx]

The Middle Ages understood that objects inclined toward the earth itself, wherever they were upon its spherical surface. In fact, gravity was sometimes described as "kindly inclining."

Dante (1265-1321) in his Inferno has his traveler and guide (Virgil) descend through the levels of Hell—not a metaphorical journey, but descending deeper and deeper below the surface of the Earth—finally reaching the gigantic body of Lucifer embedded in the ice. They start climbing down his body when, at his groin region (the bottom-most part of the world), down becomes up, and they have to reverse their orientation. They are now climbing up to his feet.

Was Dante just speaking metaphorically? Did he understand gravity as it operates at the center of the Earth?

Maybe he did. Vincent of Beauvais (c.1190 - 1264) wrote an encyclopedia that was very popular in the Middle Ages. It is not unexpected that Dante would have been very familiar with it. Vincent was well aware of the spheroid nature of the Earth, and that objects fell directly to Earth no matter where they were on the surface. In his Speculum Naturale ["Mirror of Nature"], he explains as much of the world as he can in 3,718 chapters spread across 32 books. In Book vi, he tells the curious what would happen to a stone dropped into a hole that goes straight through the globe to the other side. He says that it would not fight gravity and rise to the other side, but would stay at the center.

The acceptance of a terrestrial globe forced scholars and philosophers to re-think the action of falling bodies and their relationship to the Earth. Common sense led them to arrive at the proper effects of gravity, even if they did not have the science or mathematics to understand the cause of gravity.

Old New Year

Clearly, Old New Year is still a big deal!

Happy New Year!

Today, 14 January,* is the "original" New Year's Day in the Julian calendar at the time that the Gregorian calendar was devised to replace it. (This switch was discussed in several places, most notably here and here.) As can be expected, not everyone adopted the new calendar system right away. Some hung onto the Julian calendar for a long time; in fact, it wasn't until 24 January 1918 that Lenin made the Gregorian calendar the law of the land in Russia.

By the early 20th century, the Julian and Gregorian calendars were separated by two weeks (not the 7 days that were the case centuries earlier in the time of Gervase of Canterbury, or even the 10 days that were the case in the 16th century when a whole chunk of October disappeared from European countries).

It turns out that Lenin did not actually change New Year's Day in Russia so much as he created a second one. In Russia it is the Old New Year, a day of nostalgia and feasting. In the Eastern Orthodox liturgy, it is the Leave-taking of the Christmas season: the final "wrap-up" of Christmas.

The Old New Year is still remembered in Serbia, Georgia, Bosnia-Herzegovina and Ukraine. It is celebrated in Wales as Hen Galan ["old new year"] (at least in Gwaun Valley in Pembrokeshire) when children receive sweet treats and sing carols. Likewise, some parts of Switzerland keep up the old tradition of Alter Sylvester, described and illustrated here.

Thanks to the refusal of protestant countries to change their dating systems based on a Roman Catholic idea, some very old customs have survived into modern times.

*Sometimes Old New Year is the 13th.

St. Mungo

Today presents many opportunities to tie into previous posts. It is the date of the deaths of St. Rémy in 533, of Abbot Suger in 1151. It is the date of riots in Constantinople that destroyed half the city when the Blues and Greens fought, and the elevation of a new King of the Franks named Odo. Instead, however, let us talk about Kentigern, known to the Welsh as Cyndeyrn Garthwys, but whom the world now knows as Mungo.

Although he lived in the late 6th century, no complete biography exists before the 1185 version by the hagiographer Jocelyn of Furness. Jocelyn claims he used an Old Irish document; there is a manuscript  with a partial biography from the Cotton Library that might be what he refers to.

If we turn to Welsh geneaological tables from the Middle Ages, we learn that he was the son of King Owain of Rheged. If we are to believe Jocelyn, Owain raped a saint, Teneu, whose father then had her thrown from a hill in Lothian; she survived, fled to Fife, and there gave birth to Mungo.

In his twenties, Mungo started ministering in Strathclyde to those living in what is now Glasgow. Saint Ninian had already brought Christianity to the area, and he welcomed Mungo. An anti-Christian push by a later king prompted Mungo to travel to Wales where he spent time with Saint David (c.500 - c.589). Eventually, a new king in Strathclyde invited Mungo to return.

Mungo has some miracles to his name, such as reviving a dead pet robin and finding a fish in the River Clyde that had swallowed an important ring needed to prove the queen's fidelity to her husband.

Mungo is said to have died in his bath on 13 January (in either 603 or 612 or 614), now considered his feast day. He is the patron saint of Glasgow.

Traveling to Canterbury

St. Adrian of Canterbury

Yesterday's post on the Leiden Glossary mentioned its two chief contributors, Adrian of Canterbury and Theodore of Tarsus. Also interesting is their journey to Canterbury—not just their appointment to their positions, but what it took to get to their new jobs—and what it tells us about the Middle Ages.

Bede tells the story of Adrian of Canterbury in his Historia ecclesiastic gentis Anglorum ["Ecclesiastical history of the English people"]. Adrian was born in North Africa—we don't know when, but he died about 710—and was abbot of a monastery when Pope Vitalian (who would send Benedict Biscop to England as well) offered him the position of Archbishop of Canterbury on the death of Archbishop Deusdedit in 664. Adrian turned down the offer, and suggested a nearby monk, who also declined. When the pope asked Adrian a second time, Adrian introduced to the pope another friend who happened to be in Rome, Theodore of Tarsus.

The pope accepted Theodore as the new Archbishop of Canterbury, but asked that Adrian accompany him to England; according to Bede, Adrian had traveled to England twice before, and knew the way. Keep in mind that this is a world without roadmaps, without highways, without public transportation or any regularly scheduled wagons or boats or anything of the kind.

On 27 May 668 (note: 4 years after the death of Deusdedit), Adrian and Theodore left Rome. They traveled by sea to Marseille on the southern coast of France (far preferable to crossing the Alps). In nearby Arles they stayed for a time with its archbishop, John, until they managed to get passports from King Clotaire III's Mayor of the Palace, Ebroin. These passports could be shown to any civil servants along the way to grant them safe passage through Clotaire's domain.

By the time they made their way to the north of France, winter had come, so they needed to stay somewhere. Theodore went to stay with the Bishop of Paris. Adrian stayed first with the Bishop of Sens, then the Bishop of Meaux.

In the spring of 669, King Ecgberht of Kent sent for Theodore, who reached England a whole year after he first set out. Adrian, however, was not so lucky. For some reason, Ebroin decided that Adrian might have been an agent of the Greek emperor.* The Greek emperor that he feared had died in September of 668, but news could travel as slowly as bishops crossing France, so Ebroin (and Clotaire) were probably fearing someone that had been dead for months. They finally allowed Adrian to leave France.

Arriving in England, Adrian was made abbot of the monastery of St. Peter, which was re-named St. Augustine's Abbey. He and Theodore taught and wrote commentaries that, along with the writing of others, were compiled into a collection of glosses in Latin and Anglo-Saxon. At least one copy made its way to the continent and the Abbey of St. Gall, where it was copied in 800. That copy eventually wound up in the Netherlands, where it became known as the Leiden Glossary.

*In 669 the emperor would have been Constantine IV, "The Bearded"; Ebroin probably feared the emperor's predecessor, his father Constans II.

The Leiden Glossary

You can get your own copy here

The Leiden University Library in the Netherlands, founded in 1575, was an important part of the Enlightenment (late 17th to early 18th century), due to its enormous collection of texts that include 2500 medieval manuscripts. One of their medieval manuscripts, the Leiden Glossary, preserves a document from 9th century England that might otherwise be lost to us.

A "glossary" is a collection of "glosses," or explanations of a word or term. The Leiden Glossary contains glosses and commentaries by two priests and scholars, Adrian of Canterbury and Theodore of Tarsus (mentioned here), who were both at St. Augustine's Abbey in Canterbury.

The 48 chapters are lists of sayings and phrases used by Adrian and Theodore in their teaching, as well as commentaries they made on other works: think of it as a teacher's handout to his students so they don't have to take notes. There are, for instance, 8 chapters by Theodore with glosses on the "Pastoral Care" of Pope Gregory I (Gregory has been mentioned here).

There are also glosses from different people. For instance, there are three glosses on the same subject of the Historia Ecclesiastica ["History of the Church"] of Eusebius. The three are of differing quality, as if the book records the attempts by three different scholars—maybe students— to explain the passages in Eusebius. One of them echoes a different commentary found elsewhere that is known to be by Aldhelm, so it may have been Aldhelm himself who contributed it to the Leiden.

The Leiden is a mixture of glosses in Latin and Anglo-Saxon, another indication that the original glossary must have come from England. The Leiden Glossary was made in the library at the Abbey of St. Gall, presumably from that original. One of the things that we learn collaterally from the Leiden Glossary—because of the manuscripts about which the glosses have been written—is that the library at St. Augustine's Abbey must have been extensive. Alas, it did not survive the dissolution of the monasteries under Henry VIII.

Conjoined Twins

from a 1499 woodcut by Jacob Locher

Hippocrates was aware of the phenomenon of conjoined twins, and offered an explanation: the male provided too much seed for just one being and yet not enough for two.

Whatever the reason, antiquity and the Middle Ages were well acquainted with this occurrence. Not everyone would have had opportunity to see an example of conjoined twins—there's no evidence that Hippocrates himself ever saw or "treated" such a case—but some who did witness the phenomenon wrote about it. One eyewitness was Leo Diaconus, or Leo the Deacon.

Leo the Deacon was a Byzantine historian who was born about 950. After 992 he started a history of the Empire, for some reigns of which he is our only source. His writing style has been criticized, but his facts have not. He reports:

At this time male twins, who came from the region of Cappadocia, were wandering through many parts of the Roman Empire; I myself, who am writing these lines, have often seen them in Asia, a monstrous and novel wonder. For the various parts of their bodies were whole and complete, but their sides were attached from the armpit to the hip, uniting their bodies and combining them into one. And with the adjacent arms they embraced each other’s necks, and in the others carried staffs, on which they supported themselves as they walked. They were thirty years old and well developed physically, appearing youthful and vigorous. On long journeys they used to ride on a mule, sitting sideways on the saddle in the female fashion, and they had indescribably sweet and good dispositions. [Leo Diaconus]

The pair lived for several years, apparently making appearances around the Eastern Empire (perhaps earning money for some 10th century P.T.Barnum). Eventually, one twin died.

...skilled doctors separated them cleverly at the line of connection with the hope of saving the surviving one but after living three days he died also. [Theophanes Continuatus]

A history written in the 11th century has an illustrated page for the case of these conjoined twins. You can see the pictures here.

[Today's post is inspired by a recent item on medievalists.net, a blog I recommend.]

Emperor Justinian

The results of Justinian's plan for re-unifying the Empire

The Byzantine Emperor Justinian was known for—among other things—establishing a code of justice. His reign, from 1 August 527 until 14 November 565, was sufficiently long that he managed to achieve many other things—enough that he earned the title Justinian the Great.

When I call him a Byzantine Emperor, I refer to a geographical designation; technically, he was emperor of the Roman Empire, albeit he ruled from the Eastern Empire. The division of the vast Roman Empire made it difficult to manage the entire territory; Justinian, however, decided during his reign that it was time to bring the empire back together.

Now, this might have been easy if the Western Empire were still under Roman rule. The Western Empire, however, had been overrun by Goths and Vandals. Justinian, who is sometimes referred to as the "Last Roman Emperor" because he was the last ruler who spoke Latin as his first language (as opposed to Greek), instituted a renovatio imperii ["restoration of the empire].

This restoration plan produced the Gothic Wars, lasting 20 years, Not only did he bring much of the old Roman territory around the Mediterranean back under one rule, but he also brought new territory to the Empire. The Tzani (now called the Zans, a subtonic group of the Georgians) on the east coast of the Black Sea had never known Roman rule, but were included in his military campaigns.

Treating Corpses

A medieval reliquary from the collection in the
Metropolitan Museum of Art

Over a year ago I touched on funeral practices. A recent comment on that post has sent me back to look at, shall we say, "divergent practices." The comment was very pertinent: how do we account for attitudes toward saints' relics if preserving corpses was important?

It is important to remember that the Middle Ages is a thousand years of many different cultures; there will be no answers that account for all circumstances:

In medieval times the practice of body partition, artistic or actual, was fraught with "ambivalence, controversy, and profound inconsistency." The culture of ancient Rome had possessed strong taboos against moving or dividing corpses, and Christians of the third and fourth centuries maintained this intense concern for proper burial. Indeed, the belief that corporeal integrity is crucial to identity runs throughout medieval culture. The Parisian theologian Gervase of Mt.-St.-Eloi, for example, insisted that it was better to bury bodies intact so they would be "ready for the trumpet" (for the Last Judgment when, it was believed, the soul would be reunited with the body). [source]

Of course, bodies decay, and if Christians believed in bodily resurrection, they must also believe that resurrection would restore the decaying body to its living healthful status. Apparently, however, that belief did not include being able to re-assemble limbs if they had been separated, or restoring organs and cuts if there had been an autopsy.

Research, however, shows that attitudes toward the treatment of corpses were "contextual": important bodies—ones that had religiously or politically sentimental significance—could be partitioned for special purposes. Saints' relics are the most obvious example, but there were others. When Henry III died in 1272, he was interred in Westminster Abbey, but in 1292 his heart was removed and sent to Fontevrault Abbey because of his Angevin family connections.

And remember that the process of hanging, drawing and quartering was a special punishment for the worst of crimes: those who wanted to bring harm to the body of the king (and, by extension, the "body politic" of the country).

Clearly, the treatment of bodies depended on various and varying cultural attitudes, as well as on the needs of the culture to get further "value" from the person by utilizing (or abusing) the corpse after his or her death.

...and Sometimes It Works

Holding hot iron in a Trial by Ordeal.

In the post on Margaret Eriksdottir we saw an example of how Trial by Ordeal doesn't always work out for the defendant. People still invoked that dubious method of justice, so belief in it (and, presumably, its efficacy in some cases) kept it alive.

The post linked above mentioned how Haakon III died without an heir, so a nephew named Guttorm Sigurdsson was put on the throne of Norway. He was only four years old, and so the responsibility of governing was put into the hands of regents. Guttorm only lived as king a few months, actually, dying of an illness (remember the sudden illness that killed his predecessor? it seems to have been a trend in Norwegian politics of the 13th century). One of his regents was Haakon the Crazy.

To give this new Haakon the benefit of the doubt, what we translate as "crazy" would probably more appropriately be defined as "furious in battle" than "unstable of mind." He was a supporter of King Sverre (Margaret's husband), and was made regent for Guttorm and leader of Norway's armies at the death of Sverre's son, Haakon III. Unfortunately, he had connections with Sweden that made him unsuitable for king, so at Guttorm's untimely death, Haakon the Crazy's half-brother Inge became king.

Haakon the Crazy died at the end of 1214; King Inge died in April 1217; and here's where it gets more interesting. A woman whom Haakon III had taken as a concubine in 1203 appeared in public with her young son, claiming that he was a son of Haakon III. Normally, this would not necessarily carry any weight, but she decided to go through a Trial by Ordeal. She carried a piece of hot iron without apparent damage from the heat, proving before all of Sweden that her claim of proper paternity for her son was true!

The boy, Haakon, became King Haakon IV and reigned from June of 1217 until his death on 16 December 1263. His reign is considered a golden age of medieval Norway.

Margaret of Sweden

Retrieving an object from boiling water without
suffering burns would prove innocence.

Margaret (or Margareta) Eriksdottir of Sweden (c.1155 - 1209) is only briefly mentioned in the histories of the time, but one incident in her life underscores the flaws of the medieval justice system.

She was the daughter of King Eric IX of Sweden (d.1160) and was married to King Sverre of Norway  (c.1151 - 1202) in 1189. Sverre fell ill and died on 9 March on his return from a military expedition. Margaret returned to Sweden after his funeral, but her daughter, Kristina, was not allowed to return with her. Sverre's successor (King Haakon III, a son from a previous marriage) kept Kristina at his court. This, presumably, caused some hostility between Margaret and Haakon.

Two years later, Margaret decided to return to Norway. Unfortunately for Margaret, Haakon died very shortly after her return, and accusations of poison were made against her.

Margaret invoked Trial by Ordeal* to prove her innocence, and had a man undergo the ritual in her place. Sadly, he was badly burned—not surprising to a modern audience, but proof of guilt to the law court of the time. The man was drowned, and Margaret had to flee for her life back to Sweden.

Haakon died without a son, so Guttorm (a grandson of Sverre) was named king, even though he was only four years old. No one was around to carry a grudge against Margaret, so in 1209 she returned to Norway for the wedding of Kristina to one of the regents for Guttorm. Sadly, she became ill and died a few weeks after the wedding.

Changing the Year

[Notate bene: this post is based on one that originally appeared on 30 June 2012.]

Pope Paul III, as played by
Peter O'Toole in "The Tudors"

In 2012, June 30th had one extra second added to it. This is only the latest in a long list of calendar corrections. We'll avoid the modern arguments about what actually constitutes a "year" (a problem resolved by designer of the Jalali calendar) 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 millennia 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 it's important if you want to declare the anniversary of an event.

Anyway, the extra second was added just before midnight. You may not have noticed it, but you can say you lived at a 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 him, Copernicus probably would have come running to join the team of calendar reformers; alas, he had died in 1542.
