Basilica of San Zeno

Theodoric as King of Italy did not just want to be king of the land; rather, he wanted to be seen as king or custodian of or successor to the Roman Empire. He therefore restored and renovated many public buildings as well as building new ones.

One of these new buildings was a small church built for St. Zeno. Zeno of Verona (c.300 - 371) was an early saint with a couple of backstories. One says that he came from Mauretania, an area in Africa known for Berbers, where he tutored children in their schoolwork and taught them about Christianity. Another theory was that he was a follower of Athanasius, an opponent of Arianism, who visited Verona in 340. The style of the nearly 100 sermons we have from Zeno support an African origin. One tradition says he was the eighth bishop of Verona, and Gregory the Great calls him a martyr.

Zeno supposedly—among his other good works—converted man from Arianism to Roman Christianity. Despite this, the Arian Christian Theodoric thought it wise to build a church for Zeno. The place was expanded into a basilica under King Pepin of Italy (Charlemagne's son) in the 9th century. In the 10th century, Zeno's body was moved to a different church after the building was damaged by Magyars, but it was returned eventually to its original crypt. The church was rebuilt with the patronage of Holy Roman Emperor Otto I. The current expanded building was completed in 1398.

You can learn more about the church and see its interior here. The church's sculptures show scenes from Theodoric's life. One scene is Theodoric riding into Hell (see it in the previous post), but also there are depictions of Theodoric's fight with Odoacer. Not depicted, however, is a famous story having nothing to do with Theodoric but known to all. The crypt below the church, where St. Zeno's bones lie buried, is supposed to be the crypt where two young lovers killed themselves because their families denied them their union. These two families of Verona were the Montecchi and Cappelletti, although you may know them as the Montagues and Capulets.

Regarding Gregory the Great: he has been mentioned only a few times in this blog, but he made a decision once that affected the whole of English History (and probably Western Civilization) forevermore. I'll explain next time.

Theodoric Lives On!

Long after the death of Theodoric in 526, legends rose of the Germanic warrior who led his people to conquer various armies. (Theodoric even shows up on the Rök Stone.) As time passed, however, he wasn't called Theodoric of Ravenna: he was called Dietrich von Bern (of Verona). The name "Dietrich" means "Ruler of the People," which is the same definition as "Theodoric." The legends come from the late Holy Roman Empire and are largely written in Middle High German.

As is typical with the oral tradition of tale-telling, the details got muddled. Theodoric was born shortly after Attila the Hun died and a century after the Gothic King Ermanaric; he later invaded Italy and became its "king" by defeating Odoacer (the previous invader), with his capital in Ravenna. Dietrich, on the other hand, was the king of Italy already, ruling from Verona, but was forced into exile by his evil uncle, Ermenrich, and winds up at the court of Etzel (Attila) and the Huns. The switch from Ravenna to Verona suggests that the legends arose from the Lombards, whose capital was Verona (Ravenna was still part of the Byzantine culture).

Dietrich also differed from Theodoric in that he sometimes was depicted as breathing fire. This suggests a hint of the demonic. There may be an origin of this in some of the ideas about Theodoric. A 12th-century German chronicler, Otto of Freising, wrote that Theodoric rode to Hell (while alive) on an "infernal" horse. (See the illustration, thought to represent that ride of Theodoric, who is here labeled regem stultum, "stupid king," on the church portal of San Zeno Maggiore in Verona.) Some traditions called Theodoric a son of the devil. Because Theodoric was a practicing Arian, the prevailing Roman Christianity had reasons to "demonize" him.

An early (c.820) German heroic lay, Hildebrandslied, includes the story of the main character's flight alongside Dietrich to escape Odoacer, one of the few people that handed Theodoric defeats (until Theodoric negotiated a treaty and then slew Odoacer during the celebratory feast). Later legends become less and less historical, with Theodoric/Dietrich slaying a dragon, or fighting dwarves and giants.

The Church of San Zeno Maggiore, whence comes the above illustration, has a few more interesting historical tidbits I'd like to share. At first I thought it might be linked to Zeno, the Byzantine Emperor who put Theodoric in charge of the military and set him against Odoacer, but it turns out that it's a lot more interesting than that. See you tomorrow.

Theodoric's Mausoleum

Once Theodoric was King of Italy and essentially in charge of the Western Roman Empire, he did what he could to manage Rome as it would have been managed at the height of the Roman Emperors. He embarked on an extensive building/re-building project, restoring many buildings and refurbishing aqueducts, the Senate's Curia, and other valuable infrastructure.

To manage government services, he hired Boethius, a Roman aristocrat, Christian, and "renaissance man." Things were running smoothly enough that the Eastern Emperors during Theodoric's time let him be. After all, he was "letting Romans be Romans" with their own laws, while his Goths lived under their own customs and laws. Tolerance was practiced: when a synagogue in Ravenna was destroyed by a mob in 519, he ordered the city to rebuild it.

A new Eastern Emperor, Justin I, was less open to allowing the Western Empire to function independently. In 522, a problem with the Senate looked like a conspiracy against Theodoric, so he had his chief administrator, Boethius, and Boethius' father, Symmachus, arrested in 523. While in prison, Boethius wrote his Consolation of Philosophy. He was executed in 524.

Two years later, Theodoric died of dysentery while planning to attack the Vandals after their King Hilderic killed Theodoric's sister, Amalafrida (well, she was trying to change succession rules after her husband, the Vandal King Thrasamund, died). With no male heir, Theodoric's grandson Athalaric succeeded him; Theodoric's daughter and Athalaric's mother was regent.

Theodoric's Mausoleum (pictured above) was part of his Roman rebuilding campaign. In it, his sarcophagus consists of a porphyry tub from a Roman bath situated in the center of a second story. Made of very large stone blocks from a quarry 249 miles away, it has a roof made from a single piece of stone 33 feet in diameter. The roof alone weighs 230 tonnes (a metric tonne is 1000 kilograms or 2205 pounds). Its Gothic style is unlike Roman or Byzantine. It is a UNESCO World Heritage site, and is the only example of a 6th century royal tomb.

Theodoric's long reign, success in leading his people, and his management of the Western Roman Empire made him an important Germanic figure; so much so, that he lived on later as a German hero, Dietrich von Bern. Let's look at those legends tomorrow.

Theodoric's Successes

Odoacer was a Germanic soldier who overthrew the Western Roman Emperor Romulus Augustus (who was only a pre-teen) and declared himself King of Italy. The Eastern Roman Emperor, Zeno, asked Theodoric of the Ostrogoths to deal with the Odoacer situation. The two leaders battled for a couple years before finally negotiating a treaty to share the rule of the Western Empire and ignore Zeno's demands.

Theodoric went to Ravenna, where a feast was planned for 15 March 493 to celebrate their treaty. Theodoric made a toast to honor his co-ruler, drew his sword, and sliced Odoacer from collarbone to thigh. His men killed Odoacer's retainers, and Theodoric proclaimed himself King of Italy.

He was now King of the Ostrogoths (since 471), and King of Italy, so he had room in which his people could settle. He realized the danger of spreading some tens of thousands over too wide an area, rendering them less able to defend themselves and more difficult to gather together if he needed an army. He concentrated the Ostrogoths in Ravenna (his capital), Pavia, and Picenum. Theodoric ruled Italy from 493 until his death in 526.

Of all the "barbarian" groups that overtook Rome, Theodoric and the Ostrogoths were the ones who most wanted to maintain Roman culture. Theodoric issued his own coins (see illustration), he made laws that ensured fairness for Goths and Romans, and he mandated religious tolerance. Romans were Trinitarian Christians (literally "Roman" Catholics), while Theodoric and the Goths were Arians. He also promoted rebuilding of Roman cities, especially in Ravenna, where he rebuilt walls, aqueducts, churches, baths, and other structures and amenities.

One of his enduring buildings is his mausoleum, one of those ancient edifices that causes modern architects to ask "How did they do that?" I'll talk more about Theodoric's end tomorrow.

Theodoric's Troubles

After Theodoric (454 - 526) was made commander of the Eastern Roman Empire's forces by Emperor Zeno, you might have thought that his future was assured. Zeno, however, was annoyed when Theodoric dealt with a famine by asking—not conquering, asking—Zeno for permission to expand into new land where they might produce more food. Zeno's retaliation was to offer command of the forces to Theodoric "The Squinter" Strabo, the person whose defeat by our Theodoric earned him the command in the first place!

Theodoric was not going to suffer this insult quietly or let his people starve, so he invaded communities in the Rhodope Mountains in southeastern Europe (Bulgaria), slaughtering peasants and taking supplies. Their savagery drew an attempt from Zeno to make a truce, but Theodoric was not satisfied. He sent an emissary to Zeno, who was in Epidaurum at the time.* Meanwhile, Zeno sent soldiers to attack Theodoric's people, stealing (supposedly) 2000 wagons of supplies and capturing 5000 Ostrogoths.

Zeno made many bad political decisions—including losing the Western Roman Empire—and in 483 he offered Theodoric the position of absolute top military commander and made him consul in 484. Consuls were the chief magistrates of the Roman Republic. This position did not mean hostilities ended between Theodoric and Zeno. Theodoric continued to plunder Eastern Empire territories, approaching Constantinople itself.

Zeno engaged the Bulgars to attack Theodoric; the Bulgars were defeated. Theodoric besieged Constantinople, hoping to pressure Zeno into giving him land for the Ostrogoths. Zeno was having trouble with Odoacer, the Germanic ruler who was king of Italy, and offered Theodoric to defeat Odoacer and take Italy. Theodoric initially lost against Odoacer in 490; the two rulers spent the next few years fighting across Italy, finally negotiating a co-ruler treaty to stop the hostilities.

One of the two never intended to honor the treaty. I'll tell you which one next time.

*Epidaurum would be devastated two centuries later by Avar and Slavic invaders; citizens would flee north several miles and found a new city, Ragusa.

Theodoric the Great

There were many Theodorics in the Middle Ages, but only one was called "The Great." As the son of a king, and later a king himself, we can be certain of several details about him.

He was born in 454CE, right after his people, the Ostrogoths, freed themselves from domination by the Huns after the death of Attila a year before. That was not to say the Ostrogoths were from then on masters of their own faith. His father, Theodemir, made a treaty with Emperor Leo I of the Eastern Roman Empire. One of its conditions was Theodoric's removal to Constantinople as hostage to secure good behavior by the Ostrogoths. (There was also a tribute each year to Constantinople of 300 pounds of gold.)

Theodoric, who was about seven or eight years old, benefitted from this move. Because his father had consolidated lands that had belonged to Theodemir's brothers, the Ostrogoths ruled a large territory, making Theodoric as the next heir a valuable partner for the Empire and someone the Empire wanted to make sure would be a valuable ally in the future. He was therefore educated in reading, writing, and arithmetic by the best imperial teachers and learned far more about the world than he might have otherwise.

Theodoric was returned to his family when he was 15 or 16, and was given command of part of the Osgtrogoth kingdom held by one of his uncles. Shortly after, he proved his value to the kingdom when a Sarmatian king, Babai, attempted to invade an area near Theodoric that was under Constantinople's control. Theodoric with 6000 warriors defeated the invaders and killed Babai.

Theodoric increased his reputation in the 470s by leading military campaigns against enemies of the Goths and the Eastern Roman Empire. When Theodoric was successful against Theodoric the Squinter, a Thracian Goth who had led a revolt against the Emperor Zeno, Zeno rewarded him with command of the Eastern Roman forces.

In 471, he was made King of the Ostrogoths. With this position and the favor of the Emperor Zeno, his star was ascendant. Zeno, however, was a fickle emperor, as we shall see next time.

Aëtius of Amida and Acne

Galen was one of the primary sources of medical expertise in Antiquity and the Early Middle Ages, often to the neglect of other authors. The works of the 6th century Aëtius of Amida have more recently undergone closer scrutiny and revealed his originality and importance in his field.

He was born in Amida in Mesopotamia (what is now the city of Diyarbakir in Turkey), but at some point moved to Constantinople. His writings refer to Petrus—the personal physician to Theodoric of the Ostrogoths—as a contemporary, which would indicate that Aëtius was writing at the end of the 5th century or early in the 6th.

As a Byzantine Greek in the 5th-to-6th centuries, he was likely a Christian.  His closeness to the emperor(s) of Constantinople can be discerned by the title sometimes attached to his name in records: κόμης ὀψικίου ("komés opsikiou"), the "chief officer" who is part of the emperor's retinue. He might have been given official duties outside of his medical profession, since he traveled to copper mines on Cyprus, and at Jericho and the Dead Sea.

His great work was Sixteen Books on Medicine, which later editors thought to organize into four tetralogies. He does quote the Greco-Roman Galen and Oribasius (personal physician to the Roman Emperor Julian), but adds much original information. Some of his work directly applied to pregnancy—or rather, avoiding such. He is known to have developed a concoction for causing a pregnancy to abort; the ingredients are not known. He also developed a contraception medicine consisting of aloe, pepper, saffron, and the seeds of the wallflower (a member of the cabbage family).

He described a condition of the skin, a particular kind of blemish that arises when one is in the "acme" of his or her life, during puberty. Due to a typographical error, however, when he described it as part of the acme (ἀκμή) of life, the word was written as ἀκνή, accidentally substituting the "n" sound in place of the "m" sound. The word "acne" never having been seen before, it was assumed that this was his name for the blemishing, and the scourge of adolescent complexions through the ages got its name.

About his contemporary, Petrus; or rather, about Petrus' chief patient: I've referred to Theodoric more than a few times, but haven't yet dug into the details of the man who was king of one thing or another from 471 to 526—a pretty substantial length of time. It's time we looked into his life in a little more detail, which we shall do tomorrow.

Mailing a Letter

Large empires such as the Roman Empire needed ways to communicate quickly and efficiently with their far-flung domains. For the Romans, it was the cursus publicus, a series of stations along the main Roman roads where messages were passed along to fresh couriers. After the decline of the empire, the value of the  cursus publicus caused it to be maintained. Theodoric maintained the Roman postal system in his own domain, as did the Carolingian Empire in theirs.

When the Carolingian Empire ended (888 CE), however, there was no longer any organized attempt for a postal system throughout any part of Europe. Kings and popes, of course, had the large staff available and could appoint someone to deliver a message, but outside of those official types of correspondence, what were the options?

One of the more efficient systems was created by Italian merchants centuries later. A lot of travel and trade used the Mediterranean, and the Mediterranean was dominated by Genoa, Florence, and Venice. Italian businesses became so large that branches were created, and the owners could not be everywhere that needed them. Orders and messages needed to be sent to subordinates, customers, deliverymen, etc.

The large businesses set up posting stations with fast horses and riders at several points along their trade routes, but eventually they realized they were duplicating each others' work. In 1357, seventeen companies in Florence collaborated on a single message delivery system. Florence to Paris was 700 miles, and ideally a message was delivered in three weeks. Weather could be a mitigating factor, but their system was the best option.

Couriers were not worthy of being named historically, but we do know one. Geoffrey Chaucer was paid nine shillings by his master, Lionel of Antwerp, to deliver letters from France to London while Lionel and his father (Edward III) took part in the Treaty of Brétigny. (Footnote: Chaucer was in London for two weeks before Lionel returned. What can an unattached page do in a fortnight? That is the frame for my mystery novel A Death in Catte Street, available via the links in the upper-right of this blog's main page.)

Lionel, a younger son of Edward III, does not get the attention given to Edward's other progeny like the Black Prince or John of Gaunt. He will get a little more of what is due him next time.

Childeric I

Childeric I was presumably a child of Merovech, and the first king of the dynasty called Merovingians. He lived from about 437 until 481 CE. Records are sketchy, but if we are to believe Gregory of Tours, Childeric in his youth was a "wild child" who was exiled to Thuringia (now central Germany) for eight years on account of debauchery and his tendency to seduce the daughters of his subjects.

While in exile, the Gallo-Roman Ægidius, who was briefly ruler of the short-lived kingdom of Soissons, started calling himself "King of the Franks." Meanwhile, in Thuringia, the Queen Basina left her husband to marry Childeric, claiming "I want to have the most powerful man in the world, even if I have to cross the ocean for him."

Later, in 463, Childeric and Ægidius fought together to repel Theodoric II and the Visigoths from Orléans. He is also reported to have fought with "Odovacrius" (Odoacer of Italy?) against the Alemanni (but not the people we usually call Alemanni).

With Basina he had all least four children. One of them, Clovis I, because king after Childeric. His other children were Audofleda, who married Theodoric the Great of the Ostrogoths; Lanthechild, who was an Arian Christian but converted when Clovis did; Albofleda, who died soon after converting with Clovis to Christianity.

In 1653, Childeric's tomb was discovered. A ring was found with the inscription CHILDIRICI REGIS (Latin: "Childeric King"), the first hard evidence that he was considered a king. The tomb included gems, gold coins, and 300 golden bees (they could have been some other insect, like cicadas, but in general they are called bees). Napoleon liked Childeric's bees as a symbol of the French empire in 1804.

Unfortunately, in November 1831, Childeric's treasures were stolen from the Bibliothèque National de France along with several kilograms of other gold treasures and melted down. Childeric's treasure is gone, except for two bees.

...which is as good a transition as any to talk about medieval beekeeping next time.

The Ostrogoths, Finally

To be fair, I have mentioned one Ostrogoth before: King Theodoric was talked about here and here. The larger culture of the Goths has been mentioned many times in this blog, but this particular group has been wanting attention. The "Ostrogoths" part of the name comes from Germanic auster meaning "eastern." Before descending on Italy, these "Eastern Goths" built an empire in the 3rd century stretching east to what is now Belarus and Ukraine; "many Ostrogothic graves have been excavated south and southeast of Kiev" [Britannica] It is believed that the difference between Ostrogoths and Visigoths is based on geography, with "Visi-" being tacked on by the Roman scholar/statesman Cassiodorus (mentioned in the first Theodoric link above).

Little is known of the Ostrogoths and Visigoths except through records from the cultures with whom they came in contact, mostly Roman. They left us no literature of their own, although we know they had their own spoken language: a Goth Christian Bishop named Wulfila (or a team working under him) designed a Goth alphabet based on Greek and used it to translate the Bible; I showed their alphabet here. A few additional Goth religious fragments exist. Other Gothic documents such as statements from Theodoric are in Latin.

Isidore of Seville wrote a history of the Goths, in which he tells us that, when they asked the Roman Emperor Valens to send them teachers to instruct them in the Christian faith, Valens (because he had strayed from the truth) sent them heretical priests who instructed them in the Arian heresy. Salvian of Marseilles, a 5th century writer in Gaul concerned with the decline of the Roman Empire, writes in his De gubernatione Dei ("On the government of God") about the vices of the Romans versus the virtues of the "barbarian" Goths. The Arian Goths are praised for the chastity, tolerance toward Catholics.

Sometimes a charismatic ruler is necessary to hold a nation together. When Attila the Hun died and his empire began to fall apart, the Ostrogoths grew in strength, especially under Theodoric, and expanded, eventually into Italy. But after Theodoric died in 526, the Ostrogoth control of Italy started to disintegrate, and the Emperor Justinian in the Eastern Empire saw his chance. He declared war on the Ostrogoths in 535. In the following two decades, much of Italy was damaged in the battles between the two armies. What is certain is that, after 554CE, no more Gothic texts are produced in Italy; the Ostrogoths seem to have lost their national identity.

Although I said I would touch on the Ostrogoths only before taking on the first Duke of Milan, I can hardly pass up the opportunity at this point in modern history to seize the opportunity given me by the Ostrogothic link to Kyiv.

Cassiodorus and Colleges

Yesterday's post mentioned Cassiodorus (c.485-c.585), a contemporary of Boethius, and his description of the relationship between Arithmetic and Music. His full name was Flavius Magnus Aurelius Cassiodorus Senator. He was not a senator; that was part of his name, although he was a statesman under Theoderic the Great, king of the Ostrogoths.

He served in several different roles in government, and his literary skills were so well recognized that he was often asked to draft important documents while he was in Ravenna. (Why Ravenna and not Rome? That is for the next post.) Whether because he was a devoted statesman, or just because of personal inclinations, his writings try to unite the cultural differences between the Eastern and Western Roman empires, between Greek and Roman cultures, between the Roman culture and the invading Goths, and even between established Christian doctrine and heresies. After his retirement from public life, he founded a monastery and turned to writing about religion.

The immediate reason for bringing him up in a medieval blog, however, is his link to medieval universities, which didn't exist for several centuries after his death. We are familiar by now with the medieval curriculum of the trivium (Grammar, Rhetoric, Logic) and the Quadrivium (Arithmetic, Music, Geometry, Astronomy). You might be surprised to know that Cassiodorus not only listed these fields of study, in that order, but also that he derives them from the study of the Bible.

In his Expositio Psalmorum ["Explanation of the Psalms"], he interprets Psalm 18.5
"Their voice resounds through all the earth, and their words to the ends of the earth"
as the teachings of the Bible being spread throughout the world, and that these teachings are the origin of secular studies. Therefore, mastering the secular arts helps bring one back to better comprehension of the Bible. This was, in fact, considered the original purpose of medieval universities: to train better clerics.

Boethius

Boethius (left, with numbers from India)
debating Pythagoras (right, with an abacus)
while Arithmetic looks on
Boethius has been mentioned in passing before for his writing. An early philosopher whose works were very important to the Middle Ages, in life he was an important public servant from a noble family who rose very high before he fell.

Anicius Manlius Severinus Boethius was born about 480 to a prominent family that had produced a couple emperors; his father became a Roman consul in 487 but died shortly thereafter, leaving Boethius to be adopted by the aristocrat and historian Symmachus. Symmachus and Boethius were fluent in Greek, which might have figured into their execution—but we are getting ahead of ourselves.

Boethius went to work for Theodoric the Great, and some of his actions on behalf of the King of the Ostrogoths have survived in the records.
  • Procuring or producing a waterclock for Theodoric to give to Gundabad of the Burgundians.
  • Finding a lyre player to perform for King Clovis.
  • Investigating irregularities in Theodoric's paymaster.
In his famous work De consolatione philosophiæ ["The Consolation of Philosophy"], which he wrote in prison, he says that his greatest accomplishment was getting his sons, Boethius and Symmachus, appointed co-consuls in 522.

Boethius did so well in his career that he was made magister officiorum ["master of duties"], responsible for overseeing all government services. That's probably where the trouble started. Kings and emperors can be mistrustful of those around them with too much power—even if the emperor gave him the power in the first place. Boethius was put in charge of reconciling the differences that had grown up between the Western Roman and Eastern Byzantine Empires. His political powers and education and ability to speak Greek (rare in the West) made him ideally suited for this. He was accused (falsely) of treasonous dealings with the Eastern Emperor Justin I against Theodoric. For this he was exiled, then executed. His adoptive father Symmachus was later put to death on the charge of collusion with Boethius to overthrow Theodoric—a charge which seems unlikely.

He was executed in 525, but his writings survived. He wrote many books, including translations of Aristotle's works on logic; Boethius' translations were the only access to Aristotle's logic available to western Europe until the 12th century. He also produced De arithmetica on the four uses of arithmetic: arithmetic, geometry, music, and astronomy.*

The Consolation of Philosophy is believed to have been written while he was in exile. It covers many topics, one of which gave the modern era the title of one of its most popular game shows. But that's a story for tomorrow.

*These are the four parts of the quadrivium, taught in medieval universities; it is likely that the curriculum was arranged thus because of Boethius.

Grammar

"Grammar" comes from the Greek gramma, meaning "letter of the alphabet" or "thing written." Their word grammatike meant "the art of letters." The Romans pulled this word into Latin unaltered, and it eventually slid into Old French where it became gramaire, and thence to Modern English and the word whose study American schoolchildren try to avoid today.


Grammar had its fans in the Classical and early Medieval eras, however, and none more zealous than Priscianus Caesariensis. We don't know too many details about Priscian, but we know he flourished around 500 CE, because that's about when his famous work on grammar appears.

According to Cassiodorus (c.485-c.585), who was writing during the administration of Theodoric of the Ostrogoths, Priscian was born in Caesarea, in what is now Algeria. Cassiodorus himself lived for a while in Constantinople, and he tells us that Priscian taught Latin in Constantinople for a time.

Priscian wrote a work called De nomine, pronomine et verbo (On noun, pronoun and verb), probably as an instructional tool for his Greek-speaking students. He also translated some Greek rhetorical exercises into Latin in Praeexercitamina (rhetorical exercises). There were also some minor works that don't concern us, because we need to talk about his 18-volume masterpiece, Institutiones grammaticae (Foundations of grammar). He patterned it works of Greek grammar by Apollonius Dyscolus and the Latin grammar of Flavius Caper. His numerous examples from Latin literature mean we have fragments of literature that would otherwise have been lost to us.

Priscian became popular: his work was quoted for the next few centuries, and copies became numerous enough—and his scholarship good enough—that this work became the standard grammar text for 1000 years after his time. We know a copy made it to England by 700; it was quoted by Bede and Aldhelm and copied by Hrabanus Maurus. It was a standard text centuries later at Oxford and Cambridge.

Manuscripts (there are about 1000 copies extant) exist from as early as the 9th century, and in 1470 it was still important enough that it was printed in Venice.
