Egypt achieved its greatest prosperity under the shadow of the Roman peace, which, in effect, depoliticized it. Roman emperors or members of their families visited Egypt—Tiberius’s nephew and adopted son, Germanicus; Vespasian and his elder son, Titus; Hadrian; Septimius Severus; Diocletian—to see the famous sights, receive the acclamations of the Alexandrian populace, attempt to ensure the loyalty of their volatile subjects, or initiate administrative reform. Occasionally its potential as a power base was realized. Vespasian, the most successful of the imperial aspirants in the “Year of the Four Emperors,” was first proclaimed emperor at Alexandria on July 1, 69 CE, in a maneuver contrived by the prefect of Egypt, Tiberius Julius Alexander. Others were less successful. Gaius Avidius Cassius, the son of a former prefect of Egypt, revolted against Marcus Aurelius in 175 CE, stimulated by false rumours of Marcus’s death, but his attempted usurpation lasted only three months. For several months in 297/298 CE Egypt was under the dominion of a mysterious usurper named Lucius Domitius Domitianus. The emperor Diocletian was present at the final capitulation of Alexandria after an eight-month siege and swore to take revenge by slaughtering the populace until the river of blood reached his horse’s knees; the threat was mitigated when his mount stumbled as he rode into the city. In gratitude, the citizens of Alexandria erected a statue of the horse.
The Romans introduced important changes in the administrative system, aimed at achieving a high level of efficiency and maximizing revenue. The duties of the prefect of Egypt combined responsibility for military security through command of the legions and cohorts, for the organization of finance and taxation, and for the administration of justice. This involved a vast mass of detailed paperwork; one document from 211 CE notes that in a period of three days 1,804 petitions were handed into the prefect’s office. But the prefect was assisted by a hierarchy of subordinate equestrian officials with expertise in particular areas.
The economic resources that this administration existed to exploit had not changed since the Ptolemaic period, but the development of a much more complex and sophisticated taxation system was a hallmark of Roman rule. Taxes in both cash and kind were assessed on land, and a bewildering variety of small taxes in cash, as well as customs dues and the like, was collected by appointed officials. A massive amount of Egypt’s grain was shipped downriver both to feed the population of Alexandria and for export to Rome. Despite frequent complaints of oppression and extortion from the taxpayers, it is not obvious that official tax rates were all that high. In fact the Roman government had actively encouraged the privatization of land and the increase of private enterprise in manufacture, commerce, and trade, and low tax rates favoured private owners and entrepreneurs. The poorer people gained their livelihood as tenants of state-owned land or of property belonging to the emperor or to wealthy private landlords, and they were relatively much more heavily burdened by rentals, which tended to remain at a fairly high level.
Overall, the degree of monetarization and complexity in the economy, even at the village level, was intense. Goods were moved around and exchanged through the medium of coin on a large scale and, in the towns and the larger villages, a high level of industrial and commercial activity developed in close conjunction with the exploitation of the predominant agricultural base. The volume of trade, both internal and external, reached its peak in the 1st and 2nd centuries CE. However, by the end of the 3rd century CE, major problems were evident.
Naturally, it was the Greek-speaking elite that continued to dictate the visibly dominant cultural pattern, though Egyptian culture was not moribund or insignificant. One proof of its continued survival can be seen in its reemergent importance in the context of Coptic Christianity in the Byzantine period. An important reminder of the mixing of the traditions comes from a family of Panopolis in the 4th century, whose members included both teachers of Greek oratory and priests in Egyptian cult tradition. The towns and villages of the Nile valley have preserved thousands of papyri that show what the literate Greeks were reading (e.g., the poems of Homer and the lyric poets, works of the Classical Greek tragedians, and comedies of Menander). The pervasiveness of the Greek literary tradition is strikingly demonstrated by evidence left by an obscure and anonymous clerk at Al-Fayyūm village of Karanis in the 2nd century CE. In copying out a long list of taxpayers, the clerk translated an Egyptian name in the list by an extremely rare Greek word that he could only have known from having read the Alexandrian Hellenistic poet Callimachus; he must have understood the etymology of the Egyptian name as well.
Alexandria continued to develop as a spectacularly beautiful city and to foster Greek culture and intellectual pursuits, though the great days of Ptolemaic court patronage of literary figures had passed. But the flourishing interest in philosophy, particularly Platonic philosophy, had important effects. The great Jewish philosopher and theologian of the 1st century, Philo of Alexandria (Philo Judaeus), brought a training in Greek philosophy to bear on his commentaries on the Bible.
Outside the Greek ambience of Alexandria, traditional Egyptian religious institutions continued to flourish in the towns and villages, but the temples were reduced to financial dependence on a state subvention (syntaxis), and they became subject to stringent control by secular bureaucrats. Nevertheless, like the Ptolemies before them, Roman emperors appear in the traditional form as Egyptian kings on temple reliefs until the mid-3rd century, and five professional hieroglyph cutters were still employed at the town of Oxyrhynchus in the 2nd century.
The key to understanding the importance of Egypt in that period lies in seeing how the Christian church came rapidly to dominate secular as well as religious institutions and to acquire a powerful interest and role in every political issue. The corollary of this was that the head of the Egyptian church, the patriarch of Alexandria, became the most influential figure within Egypt, as well as the person who could give the Egyptian clergy a powerful voice in the councils of the Eastern church. During the course of the 4th century, Egypt was divided for administrative purposes into a number of smaller units but the patriarchy was not, and its power thus far outweighed that of any local administrative official. Only the governors of groups of provinces (vicarii of dioceses) were equivalent, and the praetorian prefects and emperors were superior. When a patriarch of Alexandria was given civil authority as well, as happened in the case of Cyrus, the last patriarch under Byzantine rule, the combination was very powerful indeed.
The advance of Christianity had just as profound an effect on the social and cultural fabric of Byzantine Egypt as on the political power structure. It brought to the surface the identity of the native Egyptians in the Coptic church, which found a medium of expression in the development of the Coptic language—basically Egyptian written in Greek letters with the addition of a few characters. Coptic Christianity also developed its own distinctive art, much of it pervaded by the long-familiar motifs of Greek mythology. These motifs coexisted with representations of the Virgin and Child and with Christian parables and were expressed in decorative styles that owed a great deal to both Greek and Egyptian precedents. Although Christianity had made great inroads into the populace by 391 (the year in which the practice of the local polytheistic religions was officially made illegal), it is hardly possible to quantify it or to trace a neat and uniform progression. It engulfed its predecessors slowly and untidily. In the first half of the 5th century a polytheistic literary revival occurred, centred on the town of Panopolis, and there is evidence that fanatical monks in the area attacked non-Christian temples and stole statues and magical texts. Outside the rarefied circles in which doctrinal disputes were discussed in philosophical terms, there was a great heterogeneous mass of commitment and belief. For example, both the gnostics, who believed in redemption through knowledge, and the Manichaeans, followers of the Persian prophet Mani, clearly thought of themselves as Christians. In the 4th century a Christian community, the library of which was discovered at Najʾ Ḥammādī in 1945, was reading both canonical and apocryphal gospels as well as mystical revelatory tracts. At the lower levels of society, magical practices remained ubiquitous and were simply transferred to a Christian context.
