The End of the Vandals

The Roman Empire ultimately decided that fighting the Vandals was not in their best interests, and made peace treaties, hoping the Vandals would keep to their current boundaries. Those involved in the treaty need to act in support of one another, however. When King Hilderic was overthrown by his cousin Gelimer—partially because Hilderic was too tolerant of Catholics (Nicene Christians) for the taste of the Arian Vandals, partially because his approach to military endeavors led to a defeat by the Moors—the Byzantine Emperor Justinian I chose to come to his aid.

With the intention to restore Hilderic to the throne, the Byzantine Emperor Justinian I sent  an army to North Africa. This was the start of the 533-34 Vandalic War, Justinian's attempt at reconquest of the Western Roman Empire. The Byzantines had a stroke of luck: the Vandal army wasn't home.

The Vandal army was on its way to Sardinia to deal with a rebellion there, led by Gelimer's brother. Seeing the Byzantine army approaching, Gelimer tried to gather what remaining forces he had, but they were insufficient to stop the Byzantines, led by Belisarius, from conquering the vandal capital of Carthage. 

On 15 December 533, the two armies met again 20 miles from Carthage. When the Vandal leader Tzar (Gelimer's brother) fell, the army scattered. Belisarius advanced to the Vandal second capital of Hippo Regius, occupying it with little resistance. Gelimer surrendered in 534, and the Kingdom of the Vandals was  no more. North Africa was once more a Roman province.

So what happened then? Gelimer was offered estates in Galatia (Hilderic had been killed in prison). He was offered the rank of patrician, but he would have had to convert to Catholicism, and so refused. The Vandal soldiers were shipped to Constantinople to become a unit in the Byzantine army. The best warriors became a cavalry regiment called the Justinian Vandals, or Vandali Iustiniani, and were sent to the Persian frontier. With Byzantine soldiers staying in North Africa to maintain the imperial presence, many married Vandal women.

Some Vandals migrated back to the Iberian Peninsula. One of them, Guntarith, came back in 546 with Moorish support and killed the proconsul of the African province in Carthage. His takeover of Carthage did not last long: he was assassinated by resident Byzantines and his Moorish counterpart, Stotzas the Younger, was taken to Constantinople and executed. That was the last gasp of the Vandal Kingdom that harried Europe and Rome.

One of the only contemporary accounts of the Vandal interaction with the Roman Empire is by Prosper of Aquitaine, who is relied on for the late 4th to mid-5th century. I'll tell you more about him next time.

Fighting the Vandals, Part 3

The sacking of Rome by the Vandals motivated the Roman Empire to prepare to deal with them like never before. It certainly made the Vandals themselves feel invincible. Their king, Genseric, sent a fleet of 60 ships to attack Gaul and Italy in 456. They landed on the southern coast of Sicily at Agrigentum, where they met Ricimer.

Ricimer was a Roman general, but like many Romans, he was not Latin, but German. He is usually described as a Goth by his contemporaries, but sometimes as the product of a Suevic father and a Visigothic mother. Some surmise that he was the son of a marriage alliance between the two Germanic tribes. His sister married a Burgundian king, Gondioc, giving Ricimer additional powerful ties. The chaos that followed the sacking of Rome allowed Ricimer to consolidate military hold over much of the Western Empire.

The Battle of Agrigentum was a success for Ricimer: the Vandals retreated to their ships to escape, but Ricimer followed and defeated them in a naval battle off the coast of Corsica. A year later, a Vandal army after looting Campania (the "shin" of Italy) was ambushed and defeated by forces of the Western Emperor Majorian. Majorian was a full-blooded Roman who had been a general and achieved the throne with the support of Ricimer and another general.

Majorian made it a primary goal to defeat the Vandals decisively. His first attempt, an attack on Cartagena in 460, failed. An alliance between the Western and Eastern Empires in 468 sent (supposedly) over 1000 ships and over 50,000 soldiers. The Vandals used fireships—ships filled with combustibles, set on fire, and sent into the opposing flat to do damage and cause chaos—to disrupt the Roman navy. Over 100 ships and over 10,000 Romans died. Rome's chances of achieving any kind of domination over the Vandals faded after that.

In the 470s, Ricimer negotiated a treaty with the Vandals. Genseric ruled the Western Mediterranean from Gibraltar to Tripoli.  The Vandals started minting their own coinage, although it was only low-denomination bronze and silver coins. They adopted Roman coinage when higher value was needed. When Genseric did in 477, his son Huneric took over.

Huneric was married to Eodocia, the daughter of the Roman Emperor Valentinian III. A fervent Arian, he nonetheless allowed some tolerance to other groups, allowing the Catholics to elect a bishop (a position that had not been filled in 24 years). He did persecute Manichaeans, however, and later in life returned to harassing Catholics, exiling their bishops and trying to force conversions to Arianism.

Under Huneric and his successors, the Vandals lost much of the territory that had been conquered under Genseric. The Ostrogoths took most of Sicily. The rising presence of Moors in the Iberian Peninsula chipped away at Vandal control of the Western Mediterranean. The Vandal King Hilderic (523 - 530) was too tolerant to Catholics, creating a civil war when a strong Arian faction overthrew him, making Hilderic's cousin Gelimer king and throwing Hilderic into prison.

The Byzantine Emperor Justinian then stepped in on Hilderic's behalf. Tomorrow we'll see the result, and the dissolution of the Vandal Kingdom.

Maghreb Jews

When Jews were expelled from England (1290) and Sephardic Jews from Spain (1492) and other locations in Europe, many of them wound up in North Africa, where there were already communities of Maghrebi Jews.  Maghrebi Jews are those who migrated to North African areas that are now Morocco, Algeria, Tunisia, and Libya. "Maghrebi" or "Maghreb" means "western" and refers to the western Arabic world. Sometimes Egyptian Jews are included, but there were distinct cultural differences between those in Egypt and the Maghrebi to the west.

The illustration is a synagogue off the coast of Tunisia, on an island called Djerba. It was partially built with stones that were brought from Jerusalem, and is still visited by North African Jews.

There were likely Maghrebi Jews living in ancient Carthage (the Carthaginians were also a Semitic people). Simon of Cyrene, mentioned in three of the Gospels as a man chosen to help carry the Cross on the way to the Crucifixion, was Maghrebi: Cyrenaica was a Greek colony in eastern Libya. The Roman general Titus deported Jews to Mauretania (Northern Africa) after the Jewish-Roman War of 70CE, adding to the Jewish population.

The Vandals established kingdoms in Northern Africa early in the 5th century. They were tolerant of the different peoples in their territories. This allowed the Jewish population to grow and thrive, so much so that the Christian churches decided to curtail their influence with restrictive laws. Moreover, when Justinian I's armies overthrew the Vandals, he issued an edict that lumps Jews with Arians and heathens.

Muslim rulers tolerated Jews, but when the Visigothic king Sisebut invaded the Iberian Peninsula and persecuted those he found there, many Iberian Jews fled to Northern Africa. The influx of Sephardic Jews eventually changed the local customs of the Maghrebi Jews to a more Sephardic manner. Fez in Morocco and Tunis in Tunisia became important Sephardic rabbinical centers right up until the 20th century, when many Jews emigrated to Israel, France, and Canada.

Once again I have found that I have referred to Vandals a handful of times without ever explaining who they really were. Let's fill in that gap tomorrow.

Reviving the Justinian Code

The Byzantine Emperor Justinian I had many accomplishments, but establishing the Corpus Juris Civilis ("Body of Civil Law"), often referred to as the Code of Justinian, was one of the most lasting. The first main codification of Roman law, it influenced many modern legal systems. It was given the force of law as the sole source of legal interpretation, which made the application of law across the Empire consistent.

Although established in the 6th century, copies were extensive for the centuries that followed (no originals from the 6th century remain). City-states in northern Italy adopted the Justinian Code as they grew and needed more formal systems of law to guide them internally and in their relationships with each other. By the time Frederick I Barbarossa came to the throne it was also being used in his territories north of the Alps.

Frederick began to use the Justinian Code which not only made application of the law consistent over a large area, it also bolstered Frederick's grander claims. Based on a Roman Imperial foundation, the Code embraced the idea of the "divine right of rulership." Frederick, like many worldly rulers in the Middle Ages, was in conflict with the Church over ultimate authority. The Justinian Code gave him a reason to push forward the idea that he had divine authority to do as he liked, such as taking over northern Italy as well as Germany, and clashing with Archbishops.

The Justinian Code was also adopted as the foundation of the Napoleonic Code, which abolished feudalism.

The "divine right of kings" was a common concept in the Middle Ages. One of the earliest examples was offered in the 7th century by Adomnán of Iona; I'll tell you about him next time.

Book Burning

The rounding up and burning of the Talmud and other important Jewish works, and the Disputation of Paris, in France in the early 1240s were not the only events of their kind. Western civilization had a tradition of harassing Jews by denying them their sacred and important texts.

Emperor Justinian in 553 forbade Jews to use the Secunda Editio (Latin: "Second Edition"), apparently referring to the Midrashic commentaries on Scripture. Centuries later, Crusaders marching through Germany decided to defend Christianity long before reaching the Holy Land by confiscating Jewish works as they passed through cities, leaving behind them piles of ash.

A decade before the Disputation of Paris, a public burning of Maimonidean writings took place in Montpellier France. Like the Disputation, this was started by an "internal" dispute. Solomon ben Abraham of Montpellier was extremely orthodox and was opposed to Moses ben Maimon's philosophy, so he invited Dominican and Franciscan inquisitors to look at the writings of one whom Solomon considered a heretic. The burning took place in December 1233. The inquisitors did not stop there. About a month after the Montpellier event, the Talmud became a target; copies of it and others—an estimated 12,000 volumes—were burning publicly in Paris.

The burning of the Talmud became a common event. Louis IX ordered more confiscations in 1247 and 1248; he produced an ordinance about this in 1254, which was upheld by Philip III in 1284 and Philip IV in 1290 and 1299.

In July 1263, the Disputation of Barcelona took place at the court of King James I of Aragon between another convert from Judaism to Christianity, the Dominican Friar Pablo Christiani, and the leading Jewish scholar Moshe ben Nachman, called Nachmanides. The debate was chiefly on the question "Was Jesus the Messiah?" The Disputation is a play by Hyam Maccoby, based on the Disputation; it was made into a film in 1986 starring Christopher Lee. You can watch it on YouTube.

The Christians claimed victory, but King James gave Nachmanides 300 gold coins, and to explain that, I should next tell you about James of Aragon.

Emperor Justinian

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

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

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

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

Anthemius of Tralles

Anthemius of Tralles (c.474-c.557) was mentioned as one of the builders (along with Isidore of Miletus) of the new Hagia Sophia. We know much more about him than that, however, both about his talents...and his annoying pranks.

We have an anecdote about how he avenged himself on his neighbor, Zenon, by fashioning leather tubes that he ran to the joists of an upper room of Zenon's house, where Zeno used to entertain guests. We are told that Anthemius would, by running steam through the tube, create loud noises and vibration in he room, frightening the guests into thinking there was an earthquake. Also, he would flash incredibly bright light into Zenon's eyes with a concave mirror.

Possible? Well, he did write a treatise "On burning-glasses"; we don't have the treatise anymore, but enough of it existed in 1777 to be included in a work called Concerning wondrous machines by an L. Dupuy. He apparently studied and wrote on properties of mirrors and lenses, and supposedly described a camera obscura. He explained how to construct an ellipse using string, and he wrote a book on conic sections.

This intellectual excellence ran in the family. His father, Stephanus of Tralles, was a physician with five sons. Two of them followed in their father's footsteps, Dioscorus staying in Tralles and Alexander finding fame in Rome.  The rest pursued different professions. Metrodorus became a grammarian in Constantinople; Olympius became an expert in Roman jurisprudence.

Anthemius' knowledge of conic sections and parabolas would have supported both his work on optics (known to the later "Second Ptolemy" Alhazen ibn al-Haytham) and his architectural aspirations when designing the dome of the new Hagia Sophia. He was able to create what is called a "pendentive": a design that allows a dome to be built onto a square base.

His success with Hagia Sophia led to him being also chosen—probably by Emperor Justinian—to design flood defenses at Dara in northern Mesopotamia.

The Dome of Holy Wisdom

The greatest church in the eastern Mediterranean was the Hagia Sophia [Greek Ἁγία Σοφία - "Holy Wisdom"] in Constantinople. The first church on the site was dedicated in 360 CE, and has served as an Eastern Orthodox Cathedral, as a Roman Catholic Cathedral (from 1204, when the Fourth Crusade captured Constantinople, until 1261), as a mosque (from 1453  until 1931), and as a museum (from 1931 until the present day). It was the largest church in the world until 1520, when the Seville Cathedral was built.

When the original church was burned down during rioting,* Emperor Justinian I ordered construction of the current building in the 530s. He employed the talents of two men—we would call them "architects," although contemporary documents refer to them as "mechanics"—named Isidore of Miletus and Anthemius of Tralles. He insisted that they make a flame-proof building, so they designed it with stone and brick-and-mortar, bound in some places by iron, but with no wood anywhere. There are other dangers than fire, however.

On 7 May 558, the dome of the Hagia Sophia collapsed during an earthquake. It was rebuilt by Isidore the Younger, a nephew of Isidore of Miletus. This time, the design included 40 ribs as support, and a dome that was six meters higher. Unfortunately for the dome, the walls were constructed of less brick and more mortar, and built too quickly—they should have let the mortar cure longer in each layer before adding the next—and were consequently not as strong. The new dome also experienced collapses. The current dome contains a north section of eight ribs and a south section of six ribs from the original.


*Constantinople had two political factions, called the Blues and the Greens; their rivalry frequently became violent, resulting in property damage

Ignorance of the Law


Ignorantia juris neminem excusat.
Ignorance of the law excuses no one.

Many years ago, comedian Steve Martin offered up a monologue on avoiding a conviction for a crime by simply claiming you "forgot it was illegal." This was funny for decades ... right up until a week ago, when I read that the teenage perpetrators of the assault in Steubenville used as their defense that they "didn't know" what they were doing was wrong.

Can ignorance of the law ever be an excuse?

The Middle Ages deliberated over this topic, ultimately drawing a distinction between two classes of people: those who had no excuse not to know the law, and those who did have an excuse for their ignorance. Canon law wanted to be strict and definitive, but it recognized that there were segments of society that could not be held completely responsible for their actions.

For whom was ignorance of the law an excuse? Actually, several groups were considered exempt from presumption of knowledge of the law:
...minors, madmen, soldiers, and, in most circumstances, women were commonly believed to lack the capacity (in the case of minors and the insane) or the opportunity (in the case of soldiers and women) to know and understand the law. [Medieval Canon Law, James Brundage, p.161]
Much of medieval canon law came from Roman sources such as the Digestum Justiniani (the Digest of Justinian*) in 503. It assembled 50 books covering many topics by multiple jurists. In the Digestum, one classical jurist, Paul, draws a distinction between ignorance of the law and ignorance of fact. Although the legal system may not be able to presume that everyone knows the actual law, it must presume that everyone knows the fundamental factual difference between a good act and a bad act in their community. Otherwise, profession of one's ignorance becomes a universal excuse, and only those who are lawyers, judges, or politicians who actually make the laws would ever be able to be convicted.


Paul is also the jurist who created the basis for presumption of innocence when he wrote Ei incumbit probatio qui dicit, non qui negat. ("Proof is incumbent on him who asserts, not him who denies.") Although the accused could not avoid punishment by simply saying "I didn't know," at least he wasn't convicted based simply on another's say-so.**

*This was Emperor Justinian I (c.482-565), whose reign straddled the Classical and Medieval eras. The Digestum is not to be confused with the Corpus Juris Civilis (Body of Civil Law), the much larger compendium (sometime called the Code of Justinian) that was assembled later in his reign, of which the Digestum was only a part.

**The phrase "Innocent until proven guilty" was coined by the English lawyer Sir William Garrow in the early 19th century.

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.

He Who Would Be Santa

15th century woodcut of Nicholas
In the introduction to Arian Christianity I mentioned how discussion at the Council of Nicaea in 325 became so heated that Bishop Nicholas of Myra slapped Arius' face. Much of what we think we know about Nicholas is difficult to substantiate, but this has not stopped historians from talking about him. In fact, it is the least-documented information we have that has developed his reputation the most.

Nicholas (c.270-6 December 343) was born at Patara, in Asia Minor. As a young man he made a pilgrimage to Egypt and Palestine; upon his return he was made Bishop of Myra, not far from his city of birth. During the reign of the Emperor Diocletian, Nicholas was imprisoned, but freed once the Christian Emperor Constantine came to power.

He attended the first ecumenical council of the new Catholic Church in 325, which was called by Constantine in order to determine the (in)validity of Arianism (see the link above). Nicholas is counted among the numerous men who assembled there, and (as mentioned) became passionate about the debate.

Well, that's the story anyway. There are some lists of participants on which his name is not found, casting doubt on his presence at Nicaea. But his importance to legend is unquestioned. His popularity as a saint in Greece and Russia began early. Emperor Justinian I (483-565) built a church to Nicholas at Constantinople. He was revered in Germany during the reign of Emperor Otto II (955-983).

And you know you're an important person when they dig up your body in order to keep it safe (as monks had done in England with St. Cuthbert). In 1071 the Turks took control of most of Asia Minor. Among other things, this meant losing control of the burial site of Nicholas. Byzantium regained control under Emperor Alexios I Comnenus, but sailors from Bari in southern Italy took it upon themselves to save the saint's bones. They brought the relics to Bari in 1087, where they have remained. (Actually, they brought the major bones, leaving fragments. Venetian sailors during the First Crusade brought the remainder to Venice where they were put in a church. Scientific investigation in the 1990s proved that the bones in Bari and Venice belong to the same man.)

Traditional pawnbroker sign
The chief story of his giving nature—the story that eventually gave rise to the legend of Santa Claus—is about a man with three daughters for whom he did not have enough money for dowries. Without a dowry, marriage was unlikely, and the fear was that they would wind up as prostitutes in order to support themselves. Nicholas passed by on three consecutive nights and each night threw a bag of gold in the window, saving the future of the daughters. Because of this he has been made the patron saint of (besides children and sailors, etc.) pawnbrokers; some think the traditional image of three golden balls for a pawnbroker shop is because of the three bags of gold. A 15th century woodcut now in the British Museum (see image above) shows Nicholas laying three gold balls instead of bags into the girls' bed. (An alternate theory has the three balls connected to the Medici family heraldry.)

His feast day is today, December 6. In some countries, children put their shoes outside their doors on the evening of the 5th, and on the morning of the 6th find chocolate, coins, or trinkets.

Got Silk?

Silk was not a medieval invention. According to Chinese tradition, Empress Si-Ling-Chi in 2460 BCE watched silkworms spinning cocoons; she unwound several cocoons, then ran the strands together to make thread, then wove the result into cloth to make a robe for Emperor Huang-Ti.

The Silk Road routes
Unverifiable, but it may very well be true. What is slightly more historically documented is that China guarded the secret of this magnificent fabric for centuries, but was willing to manufacture the cloth and sell it for very high prices to others. Wealthy people from other countries would gladly pay large sums to purchase it—soft and smooth, light to wear, dyed easily—so knowledge of this material spread. India somehow figured out the secret and was manufacturing its own silk by the 2nd century CE.

Ezekiel mentions silk, which means it was known to the Middle East in the 6th century BCE. Aristotle mentions the process of dealing with the cocoons, but the knowledge must have been lost for awhile, because it seems to be a mystery to that part of the world centuries later. We are told that Julius Caesar (100-15 March 44 BCE) had silk curtains. It is thought that the Romans first encountered silk in the hands of the Parthians in the first century BCE. By the end of the 1st century CE, Rome was trading for silk with the Parthians; we don't know what kind of "mark up" the Parthians were putting on the silk that they got from the East, but it was probably substantial. Although more than silk was traded between the East and West, silk was one of the few things only available from the Far East, and so the collection of interconnected trade routes from China and India to Byzantium and Alexandria became known as the "Silk Road."

Of course, it is cheaper to manage production yourself, and the Byzantine scholar Procopius (500-565 CE) tells us how some Nestorian monks* gave the Emperor Justinian the secret: the thread comes from silkworms that could not survive transportation, but their cocoons would travel well if insulated in dung and fed on mulberry leaves when hatched. Byzantium created a thriving silk industry and supplied Europe for centuries. The silk factories were staffed by all-female crews, and so were called gynaecea—after the name given to the section of a Roman or Greek home devoted to women.

Marco Polo on the Silk Road
The cycle of industrial espionage continued, however, when Muslims, who learned the secret of silk when they conquered Persia, took over Sicily and Spain. By the 13th century, Europe was producing its own silk and purchasing less from Byzantium. By the 15th century, France had its own factories. This was necessary, according to Louis XI, because purchasing silk from Italy created a trade deficit for France of 40-50,000,000 gold écus.**

Silk is different from cotton or wool in that it is not spun; rather, two or more strands are twisted together. To produce this, new techniques were invented. The simple reel is said to have been first devised for holding strands of silk, which could be up to a mile long. Two reels would be set up to unwind simultaneously so that their strands could be twisted together in a technique called "throwing."

The Middle Ages loved silk so much that a whole new vocabulary was created to describe its uses in fabrics:
  • alexander - a striped silk
  • baldachin - a warp of gold thread with a woof of silk
  • begin - 14th century rayed silk fabric
  • camlet - half silk/half hair (such as angora)
  • cendal - woven silk material
  • ecarlate - high-quality silk
  • gauze - semi-transparent silk (from 13th century onward)
  • imperial - silk with gold thread; originally from Byzantium, later called baldachin
  • osterni - silk dyed purple
  • samite - silk with interwoven gold or silver threads
  • sarcenet - thin soft silk with slight sheen; sometimes called "shot"
  • tartaire - silk from Tartary
...and in all these centuries, it hasn't lost its luster.

*Remember the Nestorians? They were a branch of Christianity deemed heretical a century before Procopius, who made their home in the East where William Rubruck ran into them.
**Story of the Silk Road by Yiping Zhang, p.146 (I don't normally bog things down with citations—I assume you trust me!—but this number was so ... impressive that I felt the need to point to a source. It may be a huge exaggeration.
