The Iron Crown of Lombardy

The Eastern Emperor Justinian's (482-565 CE) attempt to conquer the Western Empire left it bruised and open to invasion. The Lombard Kingdom was established by Germanic tribes who flowed into the Italian peninsula after its population and political infrastructure was devastated by attacks from Byzantine forces. Between Lombards and Byzantines, Italy was carved into a series of ever-shifting boundaries for the next few centuries.

One of the early rulers of the Lombards married a Bavarian princess named Theodelinda (c.570-628). Because of actions she took that helped stamp out Arianism in Italy, she received some notable religious gifts. One of her gifts was a nail, purported to be from the True Cross and originally in the possession of Emperor Constantine (272-337), who received it from his mother, St. Helena (246-330).

The Iron Crown of Lombardy (see the inner ring?)

What does one do with an iron nail that is a relic of Christ? Turn it into an accessory!

The nail was beaten into a 1-centimeter thin band. Around this band was built a gold crown. It has six sections and is the size of a large arm ring. Historical documents suggest that it used to be larger, but a couple sections were lost and the remainder were re-positioned into the current smaller circle. Some, however, believe it was always this size and meant to be worn on the very top of the head or meant to be part of a larger ensemble. (A lot depends on the size of the original nail, which we cannot know.)

Although we believe the iron nail (the crucial antecedent to the Iron Crown) was brought to the Lombards by Theodelinda in the early 7th century, the Crown itself is believed to have been made in the 8th or early 9th century. DailyMedieval's research has found references to Carolingians taking up the Iron Crown (the "forgotten" King Carloman in 781 and Lothair in 829).

Religious authorities argued over the centuries over the validity of the nail. The Crown was alternately declared a "relic" of Christ or a fake. In 1715 the Congregation of Rites in Rome (which supervises the liturgy and sacraments) allowed that the Crown could be displayed in public as an object of veneration without committing to the authenticity of the "nail."

The Iron Crown of Lombardy is kept at the Cathedral of Monza outside of Milan. Authorities at the Cathedral point out that, despite the centuries of exposure, the inner iron ring shows no rust. A 1985 examination determined that magnets are not attracted to the "iron" ring. More research is needed.

Winchester Cathedral Begins

One of the largest cathedrals in England—in fact, one of the longest Gothic cathedrals in Europe—Winchester has been through many changes. The original building (on a site just north of the present cathedral) was founded in 642 and over time came to hold the remains of several Saxon kings.

The very long nave of Winchester

William the Conqueror, wishing to show the strength of his Norman regime after 1066 (or wishing to placate God for any sins William might have committed) began a building campaign, replacing several Saxon churches all over England with great Gothic edifices.

He also needed men to guide the dioceses connected to the new structures. For Winchester, that would be his cousin and personal chaplain, Walkelin, who was consecrated bishop in 1070 for the express purpose of running Winchester. This nepotism benefited Walkelin, who was able to "pay it forward": he made his brother Simeon the prior of Winchester, putting him in charge of the monastery that had started in 971. He later helped Simeon become Abbot of Ely. Walkelin also later advanced his nephew Gerard to become Archbishop of York.

To build the new cathedral would take materials, and since all natural resources in England belonged to the king, it was up to the king to allocate them as he saw fit. William gave Walkelin access to Hempage Wood in Hampshire, granting him as much wood for timbers and scaffolding as carpenters could produce in four days and nights. Walkelin took no chances: he assembled an army of carpenters sufficient to cut down the entirety of Hempage.

The next time William passed through Hampshire, he was at first stunned to see no Hempage Wood, then enraged when he realized what had happened. He summoned Walkelin, who dressed himself in his poorest outfit and knelt at the king's feet, offering to give up his position if only the king and he could remain friends. William relented, saying "I was as much too liberal in my grant as you were too greedy in availing yourself of it."*

The new Winchester was completed in 1093, and a grand and joyous procession of monks carried the relics of saints (especially of St. Swithin, former bishop of Winchester and patron saint of the old church) from the old building to the new.

Under William Rufus, Walkelin supposedly refused to send the king a large sum he was requesting, because Walkelin knew he could not raise the sum with taxing (and oppressing) the poor in his diocese. Instead, the bishop prayed to be delivered from the difficulty he was in. Ten days later he died, on 3 January 1098.

The Name of the Pope

It is common practice for popes of the Roman Catholic Church to take a new name—called their regnal name—upon elevation to the Throne of Peter. They will usually offer a reason for the new name. Cardinal Albino Luciani took the names of both his immediate predecessors and called himself Pope John Paul I. When he died after a very short (33 days) reign, Cardinal Karol Wojtyla chose to honor him by taking the name Pope John Paul II upon his accession.

Pope "Mercurius"

It hasn't always been thus, however. Whereas now almost all popes take the name of a saint, early popes used their own names—names that were not always common. So you had popes named Anacletus, Evaristus, Telesphorus, Hyginus, Soter, Eleuterus, Zephyrinus and others among the more common names like Felix and Boniface and John; and they only rarely needed numbers next to their names, because the likelihood of there being more than one pope named "Anterus" or "Eutychian" or "Miltiades" was slight.

The practice of taking a new name began not to honor a predecessor, however, but to avoid an embarrassment.

After the death of Pope Boniface II in October 532, there was a two-month vacancy in the position. Part of the reason for this was a (ahem) change in the process. You see, it had become common for some candidates to ensure their election through bribes and gifts. The Roman Senate forbade this practice just before the death of Boniface. Athalaric, the King of the Ostrogoths in Italy, upheld the Senate's decision, and added his own flourish: a disputed papal election that needed to come before his court would be fined 3000 solidi (a solidi was a gold coin of 4.5 grams) and the money given to the poor.

The cardinals fell into agreement on a distinguished priest of Rome, aged about 60. He was willing to take the job, but he had one concern. His Roman parents had given him a theophoric birth name—a name that honors a god in order to impart luck and protection to a child. His name was Mercurius. Father Mercurius did not think it was appropriate for a Christian pope to bear the name of a Roman god. He decided to take the name of a pope from a decade earlier who had had a good working relationship with Athalaric's grandfather.

And so Father Mercurius became Pope John II, the first pope known to have taken a new name upon election.

The New Year

Tying the start of a year to the season of spring makes perfect sense in agrarian cultures. The Romans started their year in spring for a long time, seeing March 25th as a logical "New Year's Day" because the days were clearly getting longer after that date.

The reason why they (and we) use the 25th of certain months instead of the 21st (when astronomically significant events like solstices and equinoxes take place), is because 4 days was the length of time it took for an observer without instruments to be certain that the seasons were, in fact, changing.

When Julius Caesar decided to reform the calendar in 45 BCE (adding a "leap day) each four years), he chose to start his new version on January 1. Named for Janus, the duo-visaged god of transitions and beginnings, it made sense to start a significant change at the start of his month. Friends would create good omens for the start of the year by giving each other token gifts of figs and honey, and wishing each other well for the coming year.

In the Middle Ages, the Church preferred to use a date of greater religious significance (Christian religion, that is, rather than Roman). March 25th (as The Annunciation) was sometimes used, and December 25th as Christmas, and March 1st (for convenience, since it could start a month and a year).

When Pope Gregory XIII reformed the calendar again,* he chose January 1st to be the official start of the year. He didn't cause the whole world to follow his lead. Most European countries had already settled on the "Julian solution" for the first day of the year.

Happy New Year.

*Technically, when he carried out the reforms planned by Pope Paul III.

Medieval PDAs

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts. The following is from 19 June 2012.]

Re-creation of wax tablets [link]

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.

Rosemary

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts.]

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.

Figuring out the Sun

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts. For Christmas I received A Short History of Nearly Everything by Bill Bryson. I have just read the section on the brilliant Lord Kelvin, who estimated the age of the Earth at as high as 400 million years. Interestingly, he kept revising his estimate, from 400 million to 100 million to 50 million and, finally, to 24 million. The difficulty in adhering to his longer estimates, for him and others in the burgeoning field of geology, was not that they could not imagine the Earth being older, but that for the Earth to be that old, the Sun would have to be around—and their best estimates of how the Sun worked could not imagine the nuclear forces that would allow it to produce heat continuously for hundreds of millions of years. This reminded me of the post for 10 June 2012.]

How Does the Sun Work?

Robert Grosseteste (c.1175-1235) is considered by some to be the founder of modern English intellectualism. Among other topics, he focused (pun intended) on light. One of his works sought to explain how the sun produced heat.

He first explained the three methods of heat generation:

1. An object that is hot
2. Motion/Friction
3. The scattering of rays

He determined that Method 1 cannot apply here. For heat to transfer from a hot object, there must be a medium through which it travels, and that medium will heat up during the transfer of heat. Clearly everything between the sun and us does not heat up.

He decided that Method 2 was also insufficient to explain the heat, because the motion that creates heat is caused by two substances moving in opposite directions—for instance, rubbing your hands together to warm them up—and the sun's circular motion does not act upon a second substance moving in an opposite direction: everything up there moved from east to west.

Method 3, he decided, must pertain. He reminds his reader that Euclid explained how a concave mirror can focus the sun's rays to cause a fire. He stated that the sun's rays falling upon the earth are scattered, but reflection by a mirror or refraction by a (clear) spherical body can change the direction of the rays, focusing them via the medium of the dense air and generating heat. For him, this had much to do with the denseness of the medium: he stated that the same amount of light falls on a mountaintop and scattering can be observed there, but the thinness of the medium of air disallows the generation of heat.

Anonymous IV

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts. Today's is new, however, inspired by a music CD I received: Secret Voices by the female a capella group Anonymous 4.]

In the post on the Las Huelgas Codex I mentioned that many of the pieces in the codex were new to scholars, but some were familiar. Where else had they been seen?

Notre Dame Cathedral

The collection of recorded polyphonic music produced by composers working at Notre Dame Cathedral from c.1160-c.1250 is referred to as the Notre Dame School of Polyphony. A majority of medieval polyphonic music up to this time was committed to parchment by the Notre Dame School.

This does not man, sadly, that we can set a manuscript in front of a modern musician and have the notes played as they were intended to be heard. Differences in musical notation and rhythm make it close to impossible to know precisely how these pieces were performed centuries ago. For us to make an attempt is only feasible because of analyses of music written by a handful of people. Franco of Cologne was one, John of Garland another (best estimates are that he was keeper of a bookshop in Paris who edited two treatises on music), and the later writing of the industrious student known only as Anonymous IV.*

The "Alleluia nativitatis" by Pérotin

Thanks to Anonymous IV, we have contemporary definitions of what is meant by organum (a plainchant melody with one voice added to enhance harmony), discantus ("singing apart"; a liturgical style of organum with a tenor plainchant and a second voice that moves in "contrary motion"), the rules for consonance and dissonance, and other terms and rules of polyphony.

One "ironic" result of the writing of Anonymous IV is that. through him, we know the names of two composers who would otherwise have been lost to obscurity. He writes about Léonin and Pérotin with such detail and feeling that, although Anonymous would have lived several decades after they lived and composed, they were presumably so famous that their reputations lived on in the school. Léonin and Pérotin are some of the earliest names of artists that we can actually link to their works.

As much as we have been given by the treatise of Anonymous IV, his own identity and details of his life are unknown. Two partial copies of his work survive at Bury St. Edmunds in Suffolk, England; one is from the 13th century, and one from the 14th. Clearly, his work was considered important enough to copy and preserve—but not his name. He was likely an English student who was at Notre Dame for a time in the late 13th century. Thanks to his interests, we understand more about the development of medieval polyphonic music than we otherwise would have.

*His name is the inspiration for a modern female a capella group.

The St. Scholastica Day Riot

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts.]

The St. Scholastica Day Riot was one of the most famous altercations in the history of Oxford, England.

Perhaps the most famous instance of Town vs. Gown took place on February 10, 1355, in Oxford. Two students (Roger de Chesterfield & Walter Spryngeheuse) complained about the ale at the Swyndlestock Tavern (located at the southwest corner of the intersection called Carfax). The argument led to the students flinging their drinks in the face of the tavern keeper and beating him. When the mayor of Oxford asked the university chancellor to punish the students (all students fell under the jurisdiction of the university, not the town), and the chancellor refused, a mob of students decided to attack the mayor and town. The town called for help from the surrounding countryside, and attacked the university. The resulting riot lasted two days and killed (supposedly) 63 students and 30 townspeople. [from DailyMedieval, May 18, 2012]

Appealing to the Crown did not help the town. The king held the university in high esteem, apparently, and supported its right to its own governance. The town was not allowed to prosecute students or staff of the university.

For the town's part in the conflict, its penance was for the mayor and council members to march bare-headed through the streets annually on February 10th. Moreover, each year the town was to pay a fine of 1 penny for each scholar killed. The fine of 5 shillings and threepence was paid annually until 1825. The Swindlestock Tavern itself had not existed for over a hundred years by that time. On the 600th anniversary of the Riot, a ceremony was held in which the mayor was given an honorary degree and the Vice-Chancellor of Oxford was made an Honorary Freeman of Oxford, putting (they hoped) the Town vs. Gown rivalry to rest once and for all.

The Music of Las Huelgas

From a facsimile edition of the Codex

[DailyMedieval is on semi-hiatus for the holidays, and I am re-cycling some older posts. Today's is new, however, inspired by a music CD I received: Secret Voices by the female a capella group Anonymous 4.]

The Abbey of Santa Maria la Real de Las Huelgas was founded in 1187 by Alfonso VIII of Castile, at the request of his wife, Eleanor of England, the daughter if Henry II an Eleanor of Aquitaine. It was founded on land that was going unused at the time; huelgas meant land that is fallow, although nowadays it is used to refer to "labor strikes."

Its origin granted it many royal privileges: it was exempt from taxes, held many valuable items that belonged to royal families, and became a traditional site for many royal weddings, such as that between Edward I of England and Eleanor of Castile. The monastery became Cistercian in 1199 and the burial sit for the royal family. Two of the first royal burials were the founders, Alfonso VIII and Eleanor of England.

Known for the privileges of its abbess, and for the hospital founded by Alfonso VIII, Las Huelgas gave to the modern world one more fascinating item left over from the Middle Ages: music.

In 1904, while doing research on the origins and development of Gregorian chant, two Benedictine monks found a manuscript in Las Huelgas containing 45 monophonic pieces and 141 polyphonic pieces. They are written on fairly durable parchment in red and black ink with Franconian notation (briefly discussed here and here). The Las Huelgas Codex includes many pieces familiar to scholars, but also pieces that are not recorded elsewhere.

Most of the pieces are from the late 13th century, when it is known that Las Huelgas had a 100-woman choir. We have to assume that, despite the Cistercian rules against the performance of polyphonic music, the choir of Las Huelgas performed these pieces at will, thanks to their royal patronage and privileges (the abbess was allowed for a long time to call synods, confirm abbesses of other monasteries, and even hear confession and grant absolution!).

Here is a recording of the Benedicta et venerabilis II and the Benedicamus dominu, with pictures from the Abbey's architecture and art. Enjoy!

The Christmas King

Christmas Day was not celebrated in the past with all the pomp and circumstance we grant it today. It was, however, an auspicious day. Coming four days after the winter solstice, it is the day when it is easy to confirm (without careful measurement by instruments) that the days are, indeed, growing longer and therefore the "sun is returning." This made it an important day for many pre-literate cultures, and this importance was not forgotten.

Schoolchildren learning about the history of Western Civilization all hear the story of how Charlemagne was in Rome on Christmas Day in 800, and while at mass the pope placed the crown of the Holy Roman Emperors on his head, at once elevating him to the highest temporal position in Europe and implying that the pope had power to choose and make the emperor. (Actually, the pope owed Charlemagne a favor: the people of Rome disliked him and tried to torture him, and Leo III fled to Charlemagne, asking for support. Charlemagne traveled with Leo back to Rome in November of 800 and restored him to his papal throne.)

The 25th of December was an easy day to remember, and some rulers after Charlemagne used it as the official start to their reigns.

In 1066, William the Conqueror of Normandy was crowned King of England in Westminster Abbey in London, having waited well over a month since defeating his enemies and establishing his rule.

Baldwin of Boulogne (c.1058-1118), one of the leaders of the First Crusade, was chosen to rule Jerusalem after the death of his brother, Godfrey of Bouillon. Godfrey refused the title "King," believing it was inappropriate for anyone other than Jesus Christ to be styled "king" of Jerusalem. Godfrey died in July 1100. Baldwin had no trouble either calling himself "King of Jerusalem" or driving the lesson home by being crowned in Jerusalem on the day celebrating Christ's birth.

Baldwin takes the crown of Jerusalem

Roger II of Sicily (1095-1154) started life as Count of Sicily, later becoming Duke of Apulia and Calabria. He worked to unite all the Norman-conquered lands of Sicily and southern Italy. By 1130 he was ruling over a wide area including Apulia, Calabria, Capua, Naples, and part of Spoleto. "Count" and "Duke" were no longer sufficient for his stature, and he had himself crowned the first King of Sicily on Christmas Day in 1130.

Christmas Day is a day we associate with gifts. For some people in history, Christmas "gifts" were on a much grander scale than a pair of socks.

Night of the Mothers

Were the Norse Norns/Fates the "Mothers"?

Among the notable works of the Venerable Bede (c.673-735) is De temporum ratione (The Reckoning of Time). It explains why the length of days and nights changes (Bede knew the Earth was a globe); it explains how the Sun and Moon cause the phases of the Moon, and it addresses the relationship between the Moon and the tides (but doesn't understand how the relationship works). It also includes an explanation of various calendars used by different cultures. The whole point of his scholarship was to explain how to calculate the date of Easter, that "floating Holy Day" that can be held anywhere from 22 March to 25 April.

One of the events he discusses as part of other calendars is Mōdraniht (Night of Mothers), intended to be the start of the New Year:

...began the year on the 8th kalends of January [25 December], when we celebrate the birth of the Lord. That very night, which we hold so sacred, they used to call by the heathen word Modranecht, that is, "mothers night", because (we suspect) of the ceremonies they enacted all that night. [Wallis, Faith (1999). Bede: The Reckoning of Time. Liverpool University Press.]

The 25th of December was notable in the past because it came four days after the Winter Solstice, the shortest day of the year. By the 25th, it was possible to determine even without precise measurements and instruments that the days were growing longer. The 25th therefore became a day of celebrating the returning Sun.

Who were the "Mothers" meant by Bede? We think he was referring to female spirits that had to do with mankind's welfare, and who would be sacrificed to and invoked for bounty for the coming year. Some scholars have linked them to the dísir (singular dís), female spirits that watch over the fate of Norse clans. These would be similar to the Norns of Norse mythology who function like the Fates of Greek mythology.

Bede seems to be reliable on many of the observations he makes of other cultures. Unfortunately, he did not elaborate on the "ceremonies" that he "suspected" were performed on Mōdraniht, and we have no other contemporary source for information on what the celebration entailed.

Queen Lionheart

Let us look at a classic "political marriage."

Eleanor of Aquitaine, wife of Henry II of England and  mother of Richard called Lionheart, wanted the best possible match for her son. He was originally betrothed to Princess Alys, the sister of King Philip II of France, but she saw other opportunities for him.

In 1190, while Richard was on the Third Crusade, Eleanor met with King Sancho VI of Navarre, who hosted a banquet for her in Pamplona. It is likely that Eleanor negotiated the marriage of her son to Berengaria, the daughter of Sancho and his Queen, Sancha of Castile. Berengaria had been given the fief of Monreal in 1185; that, and an alliance between Richard and Navarre, would give protection to the southern border of the Aquitaine, the province in southern France that Eleanor had given to Richard. Berengaria had other fine qualities: commentators of the time say she was both attractive and intelligent.

Eleanor decided there was no time to waste, and she (now in her 60s!) and Berengaria undertook the long journey to meet with Richard. They caught up with him in Messina on the Island of Sicily. This was possibly the first time Richard and Beregaria ever met, although some believe there was an earlier occasion when they saw each other.

Richard ended his betrothal to Alys that year (after all, there were rumors that his father was having an affair with her). Unfortunately, it was Lent during their time in Sicily, so a marriage ceremony was not appropriate. Richard embarked on the next leg of the Third Crusade, and Berengaria took ship with Richard's sister, Joan of England, the widowed Queen of Sicily.* The ladies' ship foundered off the coast of Cyprus, where Isaac Comnenus opportunistically took them prisoner. When Richard learned of this, he brought part of his army to Cyprus, defeated and captured Comnenus, and took control of Cyprus. Berengaria and Richard were married on 12 May 1191, then left Cyprus for Palestine.

Once arriving in the Holy Land, Berengaria left for Poitou. It is likely that she never saw her husband again. When Richard was going home in 1194, he was captured in Germany. Berengaria and Eleanor separately raised ransom money. Richard spent little time in England as king, and Berengaria never went there, preferring her own southern lands. She did not attend his funeral at Fontevrault.

After Richard's death, his brother John refused to pay Berengaria's pension, despite intervention by Eleanor and Pope Innocent III. John's son, Henry III, finally paid the debt of £4000. She used some of the money to found a Cistercian monastery, the Pietas Dei at L’Épau. When she died, on 23 December 1230, she was buried there, rather than at Fontevrault next to her husband.

*Richard's diversion to Sicily was to free his sister from imprisonment by the usurper, Tancredi.

The King of Sicily

Sicily, an island of less than 10,000 square miles just off the coast of Italy, would not seem to merit its own king, and for a long time it didn't have one. But just as England was brought to heel under a Norman ruler, so too did Normans take over Sicily and eventually expand its power.

Christ crowns Roger II of Sicily [art link]

Before William of Normandy conquered England, Normans were also traveling in other directions. Norman mercenaries went through southern Italy in the late 10th century, looking for employment. Originally they fought on behalf of the city-states in the region, but by the 11th century they were actually ruling the regions of Naples, Capua, Apulia, Clabria, and had carved up Sicily into several smaller counties and dukedoms.

Roger Hauteville and his brother Robert Guiscard came to southern Italy and discovered the Byzantine Greek Christians living under Muslim rule by Moors from Tunisia. In 1061 the two brothers and an army took Messina, then captured Palermo in 1071. Over the next few years they expelled the Moors, and Roger became Count of Sicily. Roger had three wives and several children. One of his last children was also named Roger.

Roger II (22 December 1095-1154) became Count of Sicily in 1105, inheriting the title (and parts of Sicily) when his elder brother died. At the age of 16, he was named Count of Sicily and Calabria. In 1122, Roger's cousin, Duke William of Apulia, accepted Roger's help in dealing with an enemy; in exchange, he offered to renounce his claims to certain lands. When William died in 1127, Roger claimed all lands that had been distributed to members of the Hauteville family on Sicily and in the Italian peninsula: Calabria and Apulia, as well as Capua.

Pope Honorius II was wary of the growing power of Normans in southern Italy and Sicily, but his attempts to counter Roger with force or politics failed. By 1129, Roger's rule of Apulia was accepted by his neighbors. When Honorius died in 1130, Roger threw his support behind Anacletus II against Innocent II. Anacletus prevailed and, despite being later declared an antipope, he was able to reward his supporter with a papal bull declaring Roger King of Sicily. Roger was undisputed ruler of the island and much of southern Italy, a worthy kingdom indeed.

Roger continued to expand his territory. When Roger's sister, Matilda, who had married Ranulf II of Alife, came to Roger claiming to have been abused by her husband, Roger took Ranulf's lands as well as his brother's county.

Pope Anacletus died in 1138, and Pope Innocent II sent an army to teach Roger a lesson: the pope mistrusted the power of the expansive Kingdom of Sicily, and wanted a buffer state between Sicily and his own territory. Innocent thought Capua would make a good neutral space between the two. His army failed, however.

The King of Sicily had a long life and accomplished numerous things, but I'll mention just one more: Roger invented a new coin that would standardize monetary exchanges throughout the Mediterranean. He named this gold coin after the duchy of Apulia: the ducat. (To be honest, this coin failed to be widely adopted. The ducat with which we are familiar was introduced by Venice in 1284.)

The End of the World

Given all the fuss about the Mayan calendar, I thought it would be fun to look at other times when people thought the world might end.

The Epistles of Paul (1st century CE) in the New Testament suggest that Jesus' return was imminent and would start the process of the end times.

Saint Clement (c.90 CE) predicted the end of the world was imminent (probably influenced by Paul).

Bishop Hilary of Poitiers (c.300-c.368) was called the "Hammer of the Arians" for his opposition to them. He claimed in 365 that Emperor Constantius II (a semi-Arian) was the Antichrist, and the Apocalypse was imminent.

Hilary's student, St. Martin of Tours (316-397), claimed the end would come by 400 CE.

Hippolytus (170-35), sometimes called the first antipope, was a great scholar who thought 500 CE was a good round number for the end of the world. The historian Sextus Julius Africanus (c.160-c.240) also thought 500 was a good round number for the end times.

In 968 CE, the army of German Emperor Otto III saw an eclipse and widely believed that the end was nigh.

In 992 CE, Good Friday (a "floating" holy day) coincided with the Feast of the Annunciation. This concurrence had been thought to be a sign of the end. A report came from Germany that the sun rose in the north, and that suns and moons were fighting in the sky. Other countries missed that sight.

In May of 1000 CE, Charlemagne's body (that's him in the illustration) was disinterred in order to fulfill a legend that an emperor would rise from his sleep to fight the Antichrist.

A belief that Jesus would return 1000 years after his death made people look to 1033 CE as a date for the beginning of the end.

Pope Innocent III, scholar that he was, added the legendary number 666 to the date of the founding of Islam, and concluded that the end would come in 1284 CE.

The Black Death was seen by many as the end.

...and so on.

Urban Blight

While other history sites were celebrating the anniversary of the coronation of King Henry II yesterday, I was thinking about the anniversary of the death of Pope Urban V (1310-1370).

Born William de Grimoard to an aristocratic family, he became a Benedictine monk and later was abbot at the Abbey of St. Victor, where he made a tribute to John Cassian. He was sent to several universities to exercise his clever mind, and became an expert in Canon Law, the laws of the Church. He taught Canon Law at Avignon, Montpelier, and Paris. Returning to Avignon from a trip to Naples, where he had been sent by Pope Innocent IV, he found the pope dead. In the conclave that followed, no clear winner could be found, and Abbot William found himself being put forward as a compromise candidate. At this point, election of a pope required that the candidate be a cardinal, and William wasn't even a bishop. A hasty ordination was arranged.

Not a fan of ostentation, he continued to wear his Benedictine habit. A fan of education, he restored a school of medicine in Montpelier. His personal physician was the most-renowned surgeon of the day. He tried to restore the papacy to Rome from Avignon. He tried to get England to pay several years' worth of payments due the papacy, and clashed with Wycliffe over it. He attempted a Crusade against the Turks, which never got off the ground.

He also took a strong stand against heretics.

In 1363, he proclaimed the papal bull In caena Domini (At the table of the Lord), a collection of pronunciations of popes that merited excommunication for transgressors, and for which only the pope could give absolution. This bull, amended to include later papal injunctions, was repeated annually on Holy Thursday or Easter Monday. It listed infringements against papal authority as well as heresies, sacrileges, and other crimes. It was used to justify many an inquisition.

Over the centuries, rulers of Europe—both Catholic and Protestant—considered In caena Domini to be an infringement on their rights as sovereigns and complained. The annual recital of it was finally ended in 1770 by Pope Clement XIV.

A Tale of Two Pots

What do a Jewish philosopher, a Greek fabulist, and a Latin poet have in common? The following story and its moral.

The Book of Ecclesiasticus (c.200-175 BCE), also called the Wisdom of Sirach, is one of the disputed books of the Old Testament. It is included in the 2nd century BCE Jewish Septuagint (the Greek version of Jewish scriptures used by Diaspora Jews), but is not considered canonical in Judaism, only in Christianity. In it there is a piece of advice:

"Have no fellowship with one that is richer than thyself. What agreement shall the earthen pot have with the kettle? For if they knock one against the other, it shall be broken." [13.2-3]

Is it possible that Sirach was a fan of the fables of Æsop (c.620-564 BCE)? Æsop has a Tale of Two Pots, one earthenware and one metal:

Two Pots, one of brass and the other of clay, stood together on the hearthstone. One day the Brass Pot proposed to the Earthen Pot that they go out into the world together. But the Earthen Pot excused himself, saying that it would be wiser for him to stay in the corner by the fire.

"It would take so little to break me," he said. "You know how fragile I am. The least shock is sure to shatter me!"

"Don't let that keep you at home," urged the Brass Pot. "I shall take very good care of you. If we should happen to meet anything hard I will step between and save you."

So the Earthen Pot at last consented, and the two set out side by side, jolting along on three stubby legs first to this side, then to that, and bumping into each other at every step. The Earthen Pot could not survive that sort of companionship very long. They had not gone ten paces before the Earthen Pot cracked, and at the next jolt he flew into a thousand pieces.

The same story crops up again in the early Middle Ages in the fables of Avianus (5th century CE). In Avianus' version, two pots are floating downstream.* The metal pot suggests that they stick together, but the clay pot wants him to keep his distance, explaining "Whether the wave crashes me into you or you into me, in either case I will be the only victim."

The moral is that one should deal with equals; socializing (or going into business) with those above your station was risky. In cultures where society was sharply divided into different classes, this was advice worth repeating.

*Apparently, Avianus was fine with pots having a conversation, but walking on legs was too unrealistic for him!

Avicenna

In 1527, when the healer and alchemist Paracelsus wanted to display his contempt for tradition, he burned a book in the town square in Basle, where he had been appointed to the university by the town council. That book, allegedly, was The Canon of Medicine by Avicenna. Paracelsus had gone too far in rejecting what was still considered a fundamental work in western medicine. He was ejected from his post at the University, and from the town itself. Avicenna was too respected, even 500 years after he wrote his books.

Abū ʿAlī al-Ḥusayn ibn ʿAbd Allāh ibn Sīnā, called by the West Avicenna (c.980-1037), was mentioned here in the context of medicine. About 40 of the 240 surviving texts that he wrote (of a total of about 450!) deal with medicine. The encyclopedic Book of Healing and the Canon became standard textbooks for centuries.

The Canon assembled the best known medical knowledge to date, including Galen (129-c.200 CE) and Hippocrates (c.460-c.370 BCE) and adding a great deal of information that seems new to Avicenna. For instance:

The 'Qanun' is an immense encyclopedia of medicine. It contains some of the most illuminating thoughts pertaining to distinction of mediastinitis from pleurisy; contagious nature of phthisis*; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases and perversions; of nervous ailments. [George Sarton, Introduction to the History of Science]

Another reason why Paracelsus would want to burn Avicenna: Paracelsus was advertising his reputation as an alchemist, and believed that with salt, sulphur and mercury you should be able to produce anything. Avicenna, however, was completely opposed to the idea of alchemy, rejecting the notion that man could improve on Nature.

One could still work with Nature, however. Besides dealing with disease and injury (such as explaining how to judge how much healthy tissue could be removed during an amputation or the removal of cancerous tumors), Avicenna promoted restoring health, not just treating disease. He believed in the importance of physical exercise, of a good diet, and of a healthful environment.

Among other innovations, he lays the groundwork for modern ophthalmology, even suggesting that the optic nerves cross over each other. He laid out careful ground rules for the preparation, administration, and testing of drugs.

It has been called "one of the most significant intellectual phenomena of all times."** The Canon of Medicine is an essential part of any curriculum that studies the history of medicine.

Wassail!

We don't talk enough about Anglo-Saxon, but the Yule season and Christmas traditions evoke Old English images and customs (at least, in the Western Hemisphere) rather than Latin/Roman culture. So let's talk about wassail.

Wassail was originally spelled Wæs hæl ("Be hale/healthy!" [pronounced with short a, to rhyme with lass gal]). The "modern" spelling became current in the late 12th/early 13th century. It is not only an imperative to be well, but also the drink used to toast each other's health in the bleak midwinter. Ralph Holinshed (1529-1580) in his Chronicles quotes a story from Geoffrey of Monmouth's (c.1100-c.1155) Historia Regum Britanniæ (History of the Kings of Britain):

A great supper therefore was prepared by Hengist at the which it pleased the king [Vortigern] to be present, and he [Hengist] appointed his daughter [Rowen], when every man began to be somewhat merry with drink, to bring in a cup of gold full of good and pleasant wine, and to present it to the king saying; “Wassail.” Which she did in such comely and decent manner, as she that knew how to do it well enough, so as the king [Vortigern] marveled greatly thereat, and not understanding what she meant by that salutation, demanded what it signified. To whom it was answered by Hengist, that she wished him well and the meaning of it was, that he should drink after her,...

Currently, many who make wassail start with red wine, but originally it was based on heated cider or ale with spices and fruit thrown in. Ale or cider mixed with sugar, cinnamon, and nutmeg was common. The hot concoction would have toasted bread tossed on it to sop up the liquid for easy consumption. A traditional carol alludes to this:

Wassail! wassail! all over the town,
Our bread it is white and our ale it is brown;
Our bowl it is made of the white maple tree;
With the wassailing bowl, we'll drink to thee.

 If you are interested, there are countless recipes online for wassail. For a modern take on old recipes, Alton Brown is always reliable. A recipe that sticks more to its roots can be found at Nourished Kitchen. For an inauthentic recipe that attempts to make wassail easy for the modern cook, you could do worse than Gode Cookery.

Wæs hæl!

A Collection of Notkers

Notker Balbulus (the Stammerer)

Yesterday's post on cheese included an anecdote about Charlemagne, attributed to Notker the Stammerer. One would think that "Notker" was an unusual name in any day and age, but it turns out to have been very popular—especially at the Abbey of St. Gall. Ekkehard IV (c.980-1056), a monk of St. Gall, continued a chronicle that had been begun by others. Through the Casus sancti Galli (Doings of Saint Gall), we learn about the history of its inhabitants.

Notker the Stammerer (c.840-912) was called "delicate of body but not of mind, stuttering of tongue but not of intellect, pushing boldly forward in things Divine, a vessel of the Holy Spirit without equal in his time" by Ekkehard. He was a prolific writer, but the work he is most known for is a collection of anecdotes about Charlemagne that has been called a "mass of legend, saga, invention and reckless blundering." Supposedly, Notker wrote De Carolo Magno (Concerning Charles the Great) in honor of a visit to St. Gall by Charlemagne's great-grandson, Charles the Fat.* It is riddled with errors, such as when it claims that the Venerable Bede (672-735) devoted a book of his Ecclesiastical History to King Pepin the Short (714-768), who did not become a king until 752; when Bede died, Pepin's grandfather, Charles Martel, was king.

Notker Labeo ("the Thick-Lipped") was a nephew of the Ekkehard clan. He lived from c.950-1022 and had a reputation in the monastery as a voracious reader. He took up translating various philosophical texts into German, for which he was later called Notker Teutonicus ("the German"). When he died, he asked that he be buried in the same clothing he had always worn, to hide the fact that he wore a heavy chain around himself to mortify the flesh.

Notker Physicus, who died in 975, was called thus (according to the Catholic Encyclopedia) because of his very strict discipline. His knowledge of medicine is praised by Ekkehard, and he is probably the same Notker who was called Notarius (notable) who was known at the court of Emperor Otto I for his skill in medicine.

There was a Notker who was a nephew of Notker Physicus, of whom we know little except that he became Abbot of St. Gall in 971 and died 15 December 975. He was considered exceptionally pious.

Yet another Notker (c.940-1008) was the provost of St. Gall and became the Bishop of Liège. He established schools that became famous and drew numerous students. He is responsible for architectural projects, such as St. John's in Liège, designed after the Aachen Cathedral.


*Charles was the son of Louis the German, the son of Louis the Pious.

Time To Talk of Cheese

Cheese-making; molds can be seen on the left.

Warm up some milk, add an acidifying agent, let it cool, drain off the whey to leave the curds, and the result is cheese. We don't know who first made cheese—the best guess is that milk stored in a vessel made from the stomach of a ruminant became cheese accidentally—but it has been around for thousands of years.

The Romans loved cheese—especially fresh goat cheese—and Pliny has much to say about the different kinds from different parts of the Empire. As cheese-making spread—often by the expansion of Roman culture into Europe—local varieties developed due to differences in climate and bacteria.

Cheese was a good addition to the Christian diet, since it was protein-heavy and could be consumed on days when meat was not allowed. A Monk of St. Gall (identified as Notker the Stammerer) wrote a biography of Charlemagne called De Carolo Magno (On Charles the Great), full of glorifying anecdotes. It has a revealing story about the emperor that involves cheese:

Now on that day, being the sixth day of the week, he was not willing to eat the flesh of beast or bird; and the bishop, being by reason of the nature of the place unable to procure fish upon the sudden, ordered some excellent cheese, rich and creamy, to be placed before him. And the most self-restrained Charles, with the readiness which he showed everywhere and on all occasions, spared the blushes of the bishop and required no better fare: but taking up his knife cut off the skin, which he thought unsavoury, and fell to on the white of the cheese. Thereupon the bishop, who was standing near like a servant, drew closer and said, "Why do you do that, lord emperor? You are throwing away the very best part." Then Charles, who deceived no one, and did not believe that anyone would deceive him, on the persuasion of the bishop put a piece of the skin in his mouth, and slowly ate it and swallowed it like butter. Then approving of the advice of the bishop, he said: "Very true, my good host," and he added: "Be sure to send me every year to Aix two cart-loads of just such cheeses." [Book I, Chapter 15]

We cannot say which variety of cheese tickled Charlemagne's palate. Gorgonzola is mentioned in 879, and cheddar around 1500, but we don't know if 9th century Gorgonzola or 16th century Cheddar tasted the same as the varieties we eat today.

Medieval Cookery has a recipe for fresh cheese, and you can find more at the Medieval Cheese Forum.

The Rotating Earth

Nicholas Oresme

While re-examining Aristotle, Jean Buridan used observation and brainpower to anticipate some of the ideas we attribute to Galileo and Newton. He carried his ideas further when he put his mind to the question of the Earth's movement.

For most scholars of the Classical and early Medieval eras, the Earth was fixed, and the Heavens rotated around the Earth once each day. Buridan didn't like this: the Heavens are so much larger than the Earth; why would God design such an inelegant system? Moving the Earth would be easier.

Ptolemy knew this could not be, because if the Earth were rotating, there would be a constant rushing of wind as the air of the atmosphere passed over the land underneath it. Buridan scoffed at this: the atmosphere would be rotating just as the land does. There was no reason to dismiss the idea that Earth rotated daily.

For Buridan, however, empirical evidence was crucial. Of course, his predecessors argued, the Earth clearly does not move; we can see that. Buridan, however, likened the situation to being in a boat on a river. An observer on a second boat that was tied to the bank would see the first boat moving, but if the observer on the second boat could not see the surrounding landscape, then he would not know which of the boats were moving. The problem, Buridan knew, was that without an outside frame of reference, one cannot tell if it is the Earth or the Heavens that is moving. He needed an experiment, and he thought of one.

...and that's when he made his mistake.

Here was his idea: shoot an arrow straight up above your head. If it comes back down where you are standing, then the Earth is stationary. If the Earth rotated under it, then the arrow would come down somewhere off to the side.

He didn't realize that the same property that moves the atmosphere along with the ground would carry the arrow along as well. It would be Buridan's most brilliant student, Nicholas Oresme (c.1325-1382), who would realize and state that the arrow moves along with the Earth and atmosphere. Lacking a way to definitively prove his ideas, however, Oresme would ultimately fall back on the Bible for guidance on this issue.

One Soul To Guide Them All

Averroes (1126-1198) undertook to explain and comment on the works of Aristotle, in an attempt to clarify the Greek philosopher's concepts. One of those concepts was the idea of man's intellect, the debate over which was both stimulating and shocking for the medieval world.

Averroes (in turban); detail, "School of Athens" (Raphael)

Aristotle distinguished between a passive intellect, which is man's predisposition to accept and hold ideas, and an active intellect, which was the agent of analysis and creativity.* The active intellect was an outside force, and the blending or convergence of the external active intellect with the internal passive intellect differed in individuals, which is why we could strive to learn and think and better ourselves intellectually, but we were still different from each other. The connection between active and passive was not the same in each person. This accounted for different and individual personalities.

This was an obvious parallel to Aristotle's Realism: the idea that there exist "universal" abstract concepts—such as "dog"—outside of our direct experience, that allow us to directly experience multiple different dogs with different characteristics (which he called "particulars") and yet understand that they were all dogs.

Averroes explained this further, and created a religious controversy.

If the active intellect was external (and from a divine source) but the less-powerful passive intellect resided in man, and it was the blending of the two that created personality and human intelligence, then what happens at death when the external active intellect is removed? As a divine and lasting and (presumably) unchanging force, it stays as it is, unaffected by its temporary connection to an individual. The human-centered passive intellect dies with the human, the active intellect withdraws, and therefore there is no individual personality that exists anymore.

For Averroes, understanding Aristotle meant that there was no survival after death of a personality. Your personality—what makes you "you"—is gone when you die, and there is no room here for a soul with your personality to exist in an afterlife.

Orthodox Mohammedan theology did not agree with this, nor did Christian theologians such as St. Bonaventure and St. Thomas Aquinas.

Averroes defense against the charge of heresy? That reason forced him to express these thoughts, but that of course he adhered to the truth as explained by his faith.

*Aristotle used the term "intelligences" to refer to the non-physical (divine, or spiritual) forces that moved the celestial spheres. Christian thinkers would later call these "angels."

Nominalism vs Realism

Realism [link]

At the foundation of philosophy is a question: what defines reality? There are several questions that are connected to this. Let us start with: when we say that a lot of different animals are all dogs, to what quality are we referring that makes the Dachsund and the Great Dane both dogs? Is there an essential quality of "dog-ness"? Some universal concept that is inclusive of all dogs, despite the particular differences between breeds?

There it is: universals and particulars.

Realism says that both universals and particulars exist. That is, we recognize that different dogs/houses/trees are those things because, although they have different particulars, there is a universal essence of dogs/houses/trees that exists. Plato and Aristotle were Realists.

Nominalism says that the world is made only of particulars. Things we see are put into categories by our thought processes and our language, not by the existence of some abstract universal. William of Ockham and Jean Buridan were Nominalists.

In the two diagrams shown, we see that in Realism, although John and David have different Particulars, they are defined by their Universal quality as human beings. Nominalism, however, shows John and David only defined by their Particulars. The category of Humanity is created by us. There is no abstract "Humanity" essence that exists independent of John and David.

Nominalism [link]

Getting at the truth produced some fascinating thought experiments. One—The Puzzle of Theseus' Ship—was posed by Plutarch (46-120 CE). The ship of Theseus was preserved in Athens for several generations. As pieces of it decayed, they were replaced with new wood, so that the ship would stay intact. If a thing is based on its particulars, then with the particulars of this ship having changed over the years, is it still Theseus' ship? If there is some universal of Theseus' ship (as Realism says) then it is still his ship. If there are only particulars (as Nominalism says) then it isn't.

British philosopher Thomas Hobbes (1588-1679) took this a step further: if all the removed pieces were assembled into a complete ship, then which is Theseus' ship? Are they both Theseus' ship? He concludes that this would be absurd.

Even the early scholars understood that there were problems with these concepts, and struggled to reconcile the issues. Still, they did their best to understand how reality worked, and how that would help them to understand everything else.

...such as whether we have individual souls. That discussion will take us back to Averroes tomorrow.

The Commentator

Statue commemorating Averroes in Córdoba

Averroes (1126-1198) was born in Córdoba into a family of distinguished jurists and scholars at a time when Islamic culture was flourishing in Spain. He probably would have spent his life as a judge if not for his mentor and friend, the physician Abu Bakr ibn Tufayl, who told him that he should write commentaries on the works of Aristotle. The problem seen by ibn Tufayl was that Aristotle was too obscure either because of the ambiguity of his own writing or the shortcomings of his translators.

Averroes, whose real name was ʾAbū al-Walīd Muḥammad bin ʾAḥmad bin Rušd, embraced the task so thoroughly that, to the West, he became known as "The Commentator." His scholarship was embraced across cultures: Jacob Anatoli translated Averroes' Commentaries into Hebrew. Anatoli's colleague and friend Michael Scot translated some directly into Latin.

He analyzed and promoted most of Aristotle (and Plato's Republic) to the known world, as well as writing dozens of books of his own. So far as we know, he did not have access to original texts—there is no evidence that he knew Greek—and so his commentaries are based on Arabic translations of Aristotle.

Unfortunately for him, his rationalist views often got him into trouble when they came up against Islamic theology (which he had studied extensively). He was, in fact, banished by a caliph to whom he had been the personal physician, because some side remarks in Averroes' writing (such as "that Venus is one of the gods") struck the caliph as blasphemous. Fortunately, Averroes was allowed to return home prior to his death.

One of his most radical ideas, based on Aristotle, was that there were multiple intellects, but only one shared soul for all of mankind. To explain that raises more questions, however, unless first we look at a debate I have been putting off for months. Tomorrow, therefore, we will (finally) discuss Nominalism vs. Realism.

Jacob Anatoli

Daily Medieval has frequently mentioned the importance of Arabic texts in the transmission of knowledge to Western Europe. Arabic, however, was not a commonly known language, and Arabs did not have a strong presence in Western Europe. Arabic culture often brushed up against Latin culture in the southern Mediterranean, as mentioned Salerno, or when a scholar such as Michael Scot made it a point to learn Arabic. Scot probably had help in the form of Jacob Anatoli.

Jacob ben Abba Mari ben Simson Anatoli (c.1194-1256) grew up in southern France, and gained such a reputation for scholarship that he was invited to Naples by Frederick II, who gathered several other academics to his court, such as Scot and Fibonacci. Anatoli became known for his translations of Arabic texts into Hebrew, and he very likely aided Michael Scot in his Arabic translations. Roger Bacon explains that Scot was aided by a Jew named Andreas, and some scholars believe "Andreas" to be a misunderstanding of "Anatoli."

Of his non-translations, the greatest work is the Malmad ha-Talmidim (the title is a pun, being interpreted either "Teacher of the Students" or "Goad to the Students"). The Malmad shows a wide range of knowledge, incorporating the Old Testament and Jewish commentators, but also the New Testament, Aristotle, Plato, and Averroes. His egalitarian approach to Christian and Muslim matters was refreshing, but Judaism still had special status; he wrote "the Greeks had chosen wisdom as their pursuit; the Romans, power; and the Jews, religiousness." He tells us that a non-Jew who seeks religious Truth should be respected by Judaism and not mocked.

Anatoli extended this intellectual courtesy to Frederick II, incorporating remarks by the emperor in his works. He also mentions a Christian whom Anatoli considers a second master (after Anatoli's own mentor, Samuel ibn Tibbon); this "master" has been equated to Michael Scot.

As for his Arabic translations, Anatoli's crucial contribution was exposing the West to the work of Averroes, one of two Arab scholars (the other was the medical expert Avicenna) whose work is considered fundamental to the Middle Ages.We'll look at Averroes tomorrow.

Defeating Eternity

How long has the universe existed? Has it been around forever? Did it have a beginning? Could it have a beginning? These questions troubled the ancients.

Aristotle in his Physics tried to answer this through reason. Everything that comes into being does so from something that already exists; matter is made from matter, after all. The matter of the universe would have to come into being from some underlying matter; it couldn't come from nothing. For the matter of the universe to come into being, some matter must have existed before it. This statement is ridiculously self-contradictory, and therefore could not be taken seriously. The universe must have always existed.

Others supported Aristotle. Critolaus (c.200-c.118 BCE) couldn't believe that human beings would ever stop simply procreating into eternity. In the Early Medieval Period, Proclus (412-485) produced De Æternitate Mundi (On the Eternity of the World) with 18 proofs.

This belief was about to collide headlong with Christianity, however. The Bible makes it clear that there was a moment of Creation. That being the case, the universe cannot have been eternal.

John Philoponus (490-570) was a prolific and controversial writer who realized that Aristotle needed to be questioned on some things. Although he would be condemned after his death as heretical for interpreting the Trinity as three gods instead of one God, he was known in his lifetime for defending the Biblical necessity of a universe with a starting point. He wrote "Against Proclus" in which he challenged every one of Proclus' arguments. The basis for his argument is simple, and referred to now as the Traversal of the Infinite. If the existence of something relies on the existence of something else prior to it, then you need to account for the existence of the prior thing. That prior thing would rely on the existence of something before that, and so on. You have to have an infinite series of assumptions that something existed before the thing that came afterward, and never actually explain where any of the substances came from. The world could not possibly be infinite, and must have been created by a divine being.

The Ring of Fire vs. The Flood

15th century portrayal of Ptolemy's map

Prior to the Age of Exploration, human beings in the western hemisphere did not attempt to travel long distances by sea and discover distant lands.* This was partially because ships that could handle a very long voyage were not able to be built or provisioned easily for such a journey.** Another reason is that the world was "known" to be shaped so that long voyages were fruitless.

Eratosthenes (c.276-c.195 BCE) had established in the Classical Era the spherical nature of the Earth through simple and clear experimentation; no one disputed that. (His math on Earth's diameter was probably a little off: the unit of measurement he used probably gave him an Earth 4000 miles larger around than it is.) What was up for debate was the question of what existed "over the horizon."

Aristotle (384-322 BCE), upon whose scholarly shoulders the Middle Ages tried to stand, loved symmetry. It made sense to him that there were five zones (from the Greek word meaning "girdle") around the Earth. The extreme top and bottom were icy cold and uninhabitable. Just inside of them were the temperate zones where humans and animals lived—note: he believed both temperate zones were inhabited. In the middle it was so hot—and clearly, the further south you go from Greece and the Mediterranean the hotter it got—that it was uninhabitable. Pliny (23-79) said that this central zone was so hot that it was actually a ring of fire and was unlivable and impassable, so we would never be able to visit the people living in the southern hemisphere.

Wait, said Christianity. That can't be. The Flood covered the whole world, and when the waters receded, the Ark of Noah came to rest on Mt. Ararat in Turkey, from which all the animals strolled away and repopulated the world. If the ring of fire at the equator is impassable, how can there be animals living beyond it? Worse, if there are people living in the southern temperate region, how are we going to reach them with the Word of God?

Proving that classical scholars did not always agree, Ptolemy presented different problems in geography. His Geography was translated and made available to Western Europe in 1406. His map (depicted above in a 15th century version printed in Ulm) showed that all you had to do was sail far enough south to reach the southern lands in the world, but he also extended the bottom of Africa eastward, enclosing the Indian Ocean. This meant you could not sail to the Indian Ocean and therefore to India, but would forever have to use the Silk Road (and incidentally pay tolls at every border crossing, something sailors get to avoid).

The Age of Exploration changed all this. In 1473, Aristotle was proved wrong with a Portuguese ship exploring the west coast of Africa passed south of the Equator. In 1488, another Portuguese ship sailed around the Cape of Good Hope and reached the Indian Ocean. India and the east were accessible by ship after all, and the Portuguese quickly established those shipping routes.

Ptolemy's Geography was erroneous in another way. He estimated the Earth's circumference at thousands of miles smaller than Eratosthenes. Since no one cared to duplicate Eratosthenes' experiments and determine the distances involved, Ptolemy might have been taken as truth by some. His estimates of the size of a spherical Earth would put Asia thousands of miles closer to Europe by sailing west. With Portugal dominating southern routes to the East, was it Ptolemy's miscalculation that prompted Spain's Columbus to try a bold plan to establish a different and (he thought) shorter route?

*Perhaps some day we'll get to some of the rare cases of accidental discovery of previously unanticipated lands.
**I have been aboard replicas of Columbus' ships; they are frighteningly small considering the journey they made.
