Paganism and Christianity, Part 2

The Emperor Theodosius I (347 - 395) embraced Christianity, so much so that he was ruled by Bishop Ambrose over the Massacre at Thessalonica (the illustration shows Ambrose preventing Theodosius from entering church to receive the Eucharist), and his Edict of Thessalonica tried to establish consistency of Christian beliefs in the Byzantine Empire, specifically by settling on the form of the Nicene Creed.

Along with this push for consistency from Theodosius (called "the Great") came a shift away from tolerating all religions. Anti-pagan laws existed (that is, those religions that did not follow the Greco-Roman gods), but there is no record of them actually being enforced. Theodosius declared Nicene Christianity the official religion of the empire, but this was mostly an attempt to stamp out the "heresy" of Arianism.

Animal sacrifice was a chief target of Christians' demand for legal changes. Altars for blood sacrifice—a central practice of pagan ritual since pre-history—were routinely smashed. Eliminating it was a primary goal of Christians who were gaining political influence. This change had started prior to Theodosius: the Emperor Julian (reigned 360-363) was pagan, but when he restored pagan altars in Antioch, Christians destroyed them again. Christians were still a minority, but they were making themselves known.

Theodosius did not want open rebellion against his decisions, so pagan temples were allowed to remain open, and worship could take place. Pagan holidays could be celebrated, but they were no longer days off from work. Animal sacrifice and divination were banned. Theodosius' praetorian prefect, Maternus Cynegius, took it upon himself to vandalize pagan shrines in the eastern provinces. When he died, however, Theodosius replaced him with a moderate pagan who offered more protection to pagan temples. The emperor also named pagans in the senate to important administrative posts.

Not all temples were destroyed; it is likely that some were converted to churches. Modern archaeology has found evidence of 120 churches that started as pagan temples. Of course, 120 out of the thousands that would have existed in the empire is not a significant percentage.

The sack of Rome by Visigoths in 410 was a shocking moment for the empire, and pagans blamed the shift to Christianity as the source of a weakened empire. This prompted Augustine of Hippo to write the work we know as The City of God, except that was not what he called it. Augustine called it De civitate Dei contra paganos, "On the City of God Against the Pagans," which would set the tone of anti-pagan thought for centuries. What he meant by that will be tomorrow's post.

Fighting the Vandals, Part 1

The Germanic tribe the Vandals made their way across Europe, into the Iberian Peninsula, and then to North Africa. There they clashed with a Roman general, Bonifacius, who after a defeat on the Numidian border barricaded himself in the city of Hippo Regius. The Vandals, led by Genseric, laid siege to Hippo Regius. This was in May of 430CE.

Hippo Regius (on the coast of what is now Algeria) had a Christian bishopric, established about 250. It was significant enough that North African church councils and synods were held there. At the time of the siege, its most famous bishop and resident was Augustine. He would have been deeply dismayed at the approach of the Vandals, who were followers of Arianism. He and the residents feared death or forced conversion if the Vandals captured the city. He was 75 years old when the siege began, so it is not surprising that he died during it, on 28 August 430.

His age and poor health were no doubt exacerbated by the lack of food. Since the siege started in May, the fields around the city were untended and supplies of grain dwindled. News of Augustine's death drew the attention of Galla Placidia, regent of the Western Roman Empire. Galla Placidia was the daughter of Emperor Theodosius I, who died in 395. Next in line was her son, Valentinian III, who was only 11 in 430, making her regent during his minority.

The North African province was an important source of grain for the empire, and Galla realized something had to be done. Her nephew, Theodosius II, was ruler of the Eastern Empire in Constantinople. She asked him to send an army to join her Italian forces to deal with the Vandals. It was led by General Aspar.

The lack of food not only weakened the city, it was also affecting Genseric's army: in summer of 431 he left Hippo. This gave General Bonifacius the chance to leave Hippo for Carthage and join Aspar. In the summer of 432, Genseric's army met the joint force of Bonifacius and Aspar and, history repeating, defeated them. Aspar eventually negotiated a treaty with Genseric, whereby the Vandals would keep Mauretania and the western part of Numidia. Genseric made Hippo his capital.

On 19 )October 439, while the citizens of Carthage were all at the hippodrome for a racing event, Genseric entered the city without opposition and took control. Carthage became his new capital, and he started calling himself King of the Vandals and Alans (an Iranian nomadic people who had been with the Vandals in their migration across Europe and Africa).

Valentinian III was now emperor in his own right, and the Vandals were his problem, especially when Genseric started looting up and down the Mediterranean. We shall look at attempts to counter the Vandals tomorrow. And what about Attila the Hun?

The Massacre of Thessalonica

The following tale, like much of early history, cannot be confirmed, but it has come down to us as an actual event with actual consequences. During the reign of the Emperor Theodosius (reigned 19 January 379 - 17 January 395), a charioteer tried to rape...someone. It may have been a servant of Butheric, a Roman general. Butheric arrested the charioteer. The general populace demanded the charioteer's release, but Butheric was having none of it. They rose up and lynched Butheric.

Theodosius decided a lesson had to be learned. When a large number was gathered in the hippodrome in Thessalonica (southeastern part of Illyricum, or northeast part of Greece, if you prefer), Theodosius (or a local officer) set his troops upon them, killing 7000. (See the 16th century engraving of the massacre above.)

Whomever ordered the massacre, Theodosius accepted responsibility for it. Ambrose, the bishop of Milan, was appalled and outraged. He wrote to Theodosius to tell him he would not be able to receive the Eucharist until he repented. Theodosius accepted this, but only after eight months of being stubborn. That is the inspiration for the painting by Rubens of Ambrose denying Theodosius entrance to the church in Milan, displayed in the previous post. (The story was sufficiently popular that van Dyke later painted the same moment in an almost identical manner to Rubens' design.)

There was an earlier clash between Ambrose and Theodosius worth noting. Theodosius' court was not in Rome, but in Milan in northern Italy (hence the Edict of Milan, not Rome). In the 380s, according to one historian [Peter Brown], the need of this northern court for food motivated landowners to oppress and misuse their tenants to produce it. Ambrose opposed what he saw as abuse of the lower classes, speaking out about the need of the rich to care for the poor as was appropriate in a Christian nation. Christianity would not, however, affect politics as much as the Edict of Thessalonica would suggest. According to Brown, "modern scholars link the decline of the Roman empire to the avarice of the rich of this era."

But let's turn from people and politics for a bit and consider a place. A (brief) history of Milan is next.

Edict of Thessalonica

Although Constantine had called the 1st Council of Nicaea to make sure there was an established orthodoxy for Christianity throughout the empire, the resulting Nicene Creed did not accurately express the beliefs of all Christians. There were still many Arians who viewed Christ's nature as subordinate to God the Father. Constantine's son in the east, Constantius, was an Arian, and even exiled some Nicene bishops. His successor, Julian, rejected Christianity personally, and supported all religions. Julian's successor, the Christian Jovian, reigned for eight months before being succeeded by another Arian, Valens. By 379, when Valens was succeeded by Theodosius I, Arianism was the dominant form of Christianity in the Eastern Empire, while Nicene Christianity was dominant in the West.

Like Constantine, Theodosius wanted to establish a single Christian orthodoxy for the empire, and he issued an edict:

It is our desire that all the various nations which are subject to our Clemency and Moderation, should continue to profess that religion which was delivered to the Romans by the divine Apostle Peter, as it has been preserved by faithful tradition, and which is now professed by the Pontiff Damasus and by Peter, Bishop of Alexandria, a man of apostolic holiness. According to the apostolic teaching and the doctrine of the Gospel, let us believe in the one deity of the Father and of the Son and of the Holy Spirit, in equal majesty and in a holy Trinity. We order the followers of this law to embrace the name of Catholic Christians; but as for the others, since, in our judgment they are foolish madmen, we decree that they shall be branded with the ignominious name of heretics, and shall not presume to give to their conventicles the name of churches. They will suffer in the first place the chastisement of the divine condemnation and in the second the punishment of our authority which in accordance with the will of Heaven we shall decide to inflict.

Note the term "Catholic Christians." "Catholic" means "universal," and was an attempt to stress that everyone should have the exact same beliefs. (Of course, threatening heretics was also supposed to be a powerful motivator.) This edict was released on 27 February 380, and was followed in 381 by the first Council of Constantinople, which slightly revised the Nicene Creed.

Of course, enforcement of the edict was going to be necessary. In 381 there was an edict that forbade heretics from settling in cities, followed in 392 and 394 by laws forbidding heretics from living in Constantinople. In 383, Theodosius ordered all non-Nicene sects to submit written creeds to him for review. He declared them all invalid (Arian, Macedonian, Anomoean), except for the Novatian Creed (their big difference was that they claimed no lapsed Christian who had performed a pagan sacrifice should be allowed back into Christianity; what distinguished them from the Donatists was that Novatians did not submit to Rome, whereas Donatists followed Rome, but felt that some of their fellow clergy were traditors. Also, Donatists were willing to welcome traditors back into the fold with a baptism, whereas Novatians did not believe in second chances. Novatians were declared schismatics, and eventually also labeled heretics and persecuted. They survived until the 8th century.

The illustration on the pages is a painting by Rubens of Theodosius being refused entry to the church in Milan by St. Ambrose. Why this was the case, why Milan was important, and what this has to do with the decline of the Empire, will be next.

Magnus Maximus, Part 1

Yesterday's post on St. Illide mentioned that he cured the daughter of Roman Emperor Magnus Maximus. Although Maximus was Emperor of Western Roman Empire for only five years (383-85 CE), he has a bearing on medieval legend, and you ought to be introduced.

[link]

Magnus Maximus (c.335-28 August, 388) was a Roman general who served in Africa, then in southwest Germany on the Danube. He went to Britain in 380 and held it against invasions by the Picts and Scots.

In 383, when the current Western Roman emperor, Gratian, became unpopular, Maximus' troops declared him emperor. Maximus took his troops and set out for Rome to take Gratian's place. Gratian and his army met Maximus near Paris, where Gratian's troops were defeated and Gratian was pursued to Lyons and killed.

But Maximus did not become emperor automatically. Gratian had a half-brother, Valentinian II, who was declared Western Emperor. Maximus continued toward Italy to overthrow Valentinian, who was only 12 years old. Valentinian had help, however, from the Eastern Emperor, Theodosius I (once mentioned here regarding the date of an eclipse). Negotiations followed, aided by Bishop Ambrose of Milan (later St. Ambrose, mentioned here disagreeing with Plato). Maximus was given the title Augustus and allowed to rule Britain, Gaul, Spain, and Africa, while Valentinian II remained on the throne of Italy. Maximus was allowed to mint coins and make laws. He is credited with the first executions for heresy (I'll get to that some day).

He did not, however, remain popular for very long. I'll talk about that tomorrow, as well as tell you about his great-great-grandson, who probably did not exist and whom you all know.

Cross-referencing an Eclipse

Diagram of an eclipse from a modern translation of Hipparchus

It is not always easy to figure out dates from classical or medieval writings. Chroniclers did not necessarily strive for the kind of historical accuracy which 21st-century audiences expect. When they wanted to be precise, they often expressed themselves in ways that do not provide a proper context for the modern scholar.

Consider, for instance, Pappus of Alexandria, whom the Encyclopedia Britannica calls "the most important mathematical author writing in Greek during the later Roman Empire." [source] He wrote many important texts, but we knew little of his life.

I mentioned the other day how Suidas' Lexicon gives us data on works and events otherwise lost to history. The entry for Pappus reads:

Alexandrian, philosopher, born in the time of the elder emperor Theodosius, when the philosopher Theon also flourished, the one who wrote about Ptolemy’s Canon. His books [are] Description of the Inhabited World; Commentary on the 4 Books of the Great Syntaxis of Ptolemy; The Rivers in Libya; Dream-Interpretations. [source]

We know that Theodosius reigned from 372-395 CE, so it gives us a time frame for Pappus. This creates a small head-scratcher, however. Pappus claims to have calculated and observed an eclipse in the month of Tybi (the fifth month of the Coptic calendar). There is a problem with this dating: no eclipse occurred during the month of Tybi during the reign of Theodosius that Pappus could have observed! Could the Suidas be wrong? Certainly. But then... what is right?

There is, as it turns out, a 10th century copy of a work by Theon of Alexandria (the one mentioned in the Suidas entry) that has a marginal note next to an entry on the Emperor Diocletian (who reigned from 284-305 CE), stating "at that time wrote Pappus." Is it possible that the composer of Suidas had access to that work and assumed that it meant Pappus flourished when Theon did? If we look closer to the reign of Diocletian, we discover that there was an eclipse in the month of Tybi which would place it (using the modern method of dating) on 18 October 320 CE. If Pappus observed it himself in 320, it isn't likely that he was flourishing over 50 years later. This places him firmly in the earlier part of the 4th century.

Pappus is far more important than as an example of the care with which modern historians must date historical events. Some of his eight-volume work on mathematics is extant; and deals with many facets of geometry and carefully lays out the mathematical findings of his predecessors and how their work builds on each other over time. He also worked on several problems such as inscribing regular polyhedrons inside a sphere, conic sections, trisecting an angle, and many more. He has a theorem named after him, as well as the Pappus chain, the Pappus configuration, and the Pappus graph.

His commentary on Ptolemy provides us with insight into some lost works of classical astronomy, such as an astronomical work by Hipparchus on eclipses (illustrated in the above figure).
