The year itself was divided according to a universal Christian calendar that gradually displaced the old Roman calendar, although it retained the Roman names for the months. The liturgical year alternated seasons of penitence and joy, beginning with Advent, the fifth Sunday before Christmas, and culminating in penitential Lent and joyful Easter and its aftermath until Advent returned. Although the unit of the week and the Sabbath were taken over from Jewish usage—displacing the older Roman divisions of the month into Kalendae, Nonae, and Ides and the nine-day market cycle—Christians began to mark time by the seven-day week and moved its holiest day to Sunday during the 4th century. Late antiquity: the reconfiguration of the Roman world
The Roman Empire of late antiquity was no longer the original empire of its founder, Augustus, nor was it even the 2nd-century entity of the emperor Marcus Aurelius. In the 3rd century the emperor, who was first called princeps (“first citizen”) and then dominus (“lord”), became divus (“divine”). The powerful religious connotations of the imperial office were adopted even by usurpers of the imperial throne, backed by their armies, who then ruled autocratically at the head of a vast bureaucratic and military organization. Internal and external crises during the 3rd and 4th centuries resulted in the division of the empire into an eastern and a western part after 285, with the east possessing a great and flourishing capital built by the emperor Constantine—Constantinople (now Istanbul)—and far more economic, political, and military resources than the western half. The administration of the entire empire was restructured to finance immense military expenditures, giving the western European provinces and frontier areas greater importance but fewer resources. Most of the population of the empire, including soldiers, were frozen hereditarily in their occupations. The Western Empire, whose capital moved north from Rome in the 4th century to a number of provincial cities—Trier, Arles, Milan, and ultimately Ravenna—became less urbanized, more ruralized, and gradually dominated by an aristocracy of landowners and military officials, most of whom lived on large villas and in newly fortified cities. The provincial economy had become increasingly rural and localized and was dominated by the needs of the vast military bases near the frontiers.
The great and small estates were worked by slaves, freedmen, and coloni (“farmers”), who had once been independent but had voluntarily or involuntarily subordinated themselves to the great landowners as their only protection against imperial tax collectors or military conscription. The landowners dispensed local justice and assembled private armies, which were powerful enough to negotiate on their subordinates’ behalf with imperial officials. Mediterranean trade diminished, and the production of more and more goods was undertaken locally, as was the organization of social, devotional, and political life.
Non-Roman peoples from beyond the frontiers—barbari (“barbarians”) or externae gentes (“foreign peoples”), as the Romans called them—had long been allowed to enter the empire individually or in families as provincial farmers and soldiers. But after 375 a number of composite Germanic peoples, many of them only recently assembled and ruled by their own new political and military elites, entered the empire as intact groups, originally by treaty with Rome and later independently. They established themselves as rulers of a number of western provinces, particularly parts of Italy, Iberia, Gaul, and Britain, often in the name of the Roman emperor and with the cooperation of many Roman provincials.
Roman ethnography classified external peoples as distinct and ethnically homogeneous groups with unchanging identities; they were part of the order of nature. Adopting this view, philologists, anthropologists, and historians in the 19th century maintained that the Germanic “tribes” that first appeared in the 3rd century were the ethnic ancestors of the “tribes” of the 5th century and that the ethnic composition of these groups remained unchanged in the interval. Late 20th-century research in ethnogenesis thoroughly demonstrated the unreliability of Roman ethnography, although modern concepts of ethnicity continue to exploit it for political purposes. The organization of late imperial Christianity
Many Roman provincials were Christian higher clergy. Between the legalization of Christianity by Constantine about 313 and the adoption of Christianity as the legal religion of Rome by the emperor Theodosius I in 380, Christian communities received immense donations of land, labour, and other gifts from emperors and wealthy converts. The Christian clergy, originally a body of community elders and managerial functionaries, gradually acquired sacramental authority and became aligned with the grades of the imperial civil service. Each civitas (community or city), an urban unit and its surrounding district, had its bishop (from the Latin episcopus, “overseer”). Because there had been more Roman civitates in the Italian and provincial European areas, there were more and usually smaller dioceses in these regions than in the distant north and east.
During the 5th and 6th centuries, bishops gradually assumed greater responsibility for supplying the cities and administering their affairs, replacing the local governments that for centuries had underpinned and constituted the local administration of the empire. Two bishops, Ambrose of Milan (339–397) and Gregory I of Rome (pope 590–604), wrote influential guidebooks on episcopal and other clerical duties and responsibilities toward congregations. These works set standards for all later bishops and are still observed in many churches.
Besides the bishops and their subordinates the priests, who tended to the spiritual and material needs of Christians living in the world—the “secular clergy”—there also existed communities of monks and religious women who had fled the world. These communities were independent, although nominally under the control of the local bishop, and they followed diverse rules of life—hence their designation as “regular clergy” (from regula, “rule”). The most influential monastic rule in Latin Christianity after the 8th century was that of Benedict of Nursia (c. 480–c. 547). Benedict’s rule provided for a monastic day of work, prayer, and contemplation, offering psychological balance in the monk’s life. It also elevated the dignity of manual labour in the service of God, long scorned by the elites of antiquity. Benedict’s monastery at Monte Cassino, south of Rome, became one of the greatest centres of Benedictine monasticism.
The origins of monasticism lay in the ascetic practices of Egyptian and Syrian monks, which were transplanted to western Europe through texts such as the 4th-century Latin translation of the Life of Saint Antony (by Patriarch Athanasius of Alexandria) and through widely traveled observers such as the theologian and monk John Cassian (360–435). These Mediterranean-wide influences were among the last examples of the communications network of the older, ecumenical Mediterranean world. Monasticism developed and sustained a powerful ascetic dimension in both Greek and Latin Christianity that increased in importance as monasticism itself came to define the ideal of clerical life in the West.
In the case of Martin (316–397), a former Roman soldier turned wandering holy man, monastic asceticism was combined with the office episcopal, as Martin eventually became bishop of Tours in Gaul. He emphasized the conversion of rural pagans, as well as ministering to the urban and rural elites. In the Iberian Peninsula the work of the monk and bishop Martin of Braga (c. 515–580) was also devoted to the religious instruction of rustics. His work provided an influential model for the later conversion of northern and eastern Europe.
