Trade in imported luxury goods ranging from wine to tableware and bronze trinkets vastly increased as traders swarmed in behind the army to exploit new markets. The profits of developing industries went similarly at first to foreign capitalists. This is clearly seen in the exploitation of silver-lead ore and even in the pottery industry. The Mendip lead field was being worked under military control as early as the year 49, but under Nero (54–68) both there and in Flintshire, and not much later also in the Derbyshire lead field, freedmen—the representatives of Roman capital—were at work. By Vespasian’s reign (69–79) organized companies (societates) of prospectors are attested. Roman citizens, who must in the context be freedmen, are also found organizing the pottery industry in the late 1st century. Large profits were made by continental businessmen in the first two centuries not only from such sources but also by the import on a vast scale of high-class pottery from Gaul and the Rhineland and on a lesser scale of glass vessels, luxury metalware, and Spanish oil and wine. A large market existed among the military, and the Britons themselves provided a second. Eventually this adverse trade balance was rectified by the gradual capture of the market by British products. Much of the exceptional prosperity of 4th-century Britain must have been due to its success in retaining available profits at home.
A final important point is the role of the Roman army in the economic development of the frontier regions. The presence as consumers of large forces in northern Britain created a revolution in previous patterns of trade and civilized settlement. Cereal production was encouraged in regions where it had been rare, and large settlements grew up in which many of the inhabitants must have been retired soldiers with an interest in the land as well as in trade and industry. Towns
Belgic Britain had large centres of population but not towns in the Roman sense of having not merely streets and public buildings but also the amenities and local autonomy of a city. In Britain these had therefore to be provided if Roman civilization and normal methods of provincial administration were to be introduced. Thus a policy of urbanization existed in which the legions, as the nearest convenient source of architects and craftsmen, played an organizing role. The earlier towns consisted of half-timbered buildings; before ad 100 only public buildings seem to have been of stone. The administrative capitals had regular street grids, a forum with basilica (public hall), public baths, and temples; a few had theatres and amphitheatres, too. With few exceptions they were undefended. In the 3rd century, town walls were provided, not so much as a precaution in unsettled times but as a means of keeping operational the earthwork defenses already provided during a crisis at the end of the 2nd century. These towns grew in size to about 100–130 acres with populations of about 5,000; a few were twice this size. The majority of towns in Roman Britain seem to have developed out of traders’ settlements in the vicinity of early garrison-forts: those that were not selected as administrative centres remained dependent for their existence on economic factors, serving either as centres of trade or manufacture or else as markets for the agricultural peasantry. They varied considerably in size. In the north, where garrisons were permanently established, quite large trading settlements grew up in their vicinity, and at least some of these would rank as towns. Villas
Apart from the exceptional establishment at Fishbourne, in West Sussex, whose Italian style and luxurious fittings show that it was the palace of King Cogidubnus, the houses of Romano-British villas had simple beginnings and were of a provincial type. A few owners were prosperous enough in the 2nd century to afford mosaics; but the great period of villa prosperity lay in the 4th century, when many villas grew to impressive size. Their importance was economic and has already been described. Much remains to be learned from full excavation of their subsidiary work buildings. Larger questions of tenure and organization are probably insoluble in the absence of documentary evidence, for it is dangerous to draw analogies from classical sources since conditions in Celtic Britain were very different from those of the Mediterranean world. Religion and culture
A great variety of religious cults were to be found. In addition to numerous Celtic deities of local or wider significance, the gods of the classical pantheon were introduced and were often identified with their Celtic counterparts. In official circles the worship of the state gods of Rome and of the imperial cult was duly observed. In addition merchants and soldiers introduced oriental cults, among them Christianity. The latter, however, made little headway until the late 4th century, though the frescoes at Lullingstone in Kent and the mosaics at Hinton St. Mary in Dorset attest its presence among villa owners. Although classical temples are sometimes found in towns, the normal temple was of the Romano-Celtic type consisting of a small square shrine and surrounding portico; temples of this type are found in town and country alike.
Romanization was strongest in the towns and among the upper classes, as would be expected; there is evidence that in the countryside Celtic continued to be spoken, though it was not written. Many people were bilinguaclass="underline" graffiti prove that even artisans wrote Latin. Evidence of the classical education of the villa owners is provided by their mosaics, which prove an acquaintance with classical mythology and even with the Aeneid of Virgil. Sculpture and wall painting were both novelties in Roman Britain. Statues or busts in bronze or marble were imported from Gaulish or Mediterranean workshops, but British sculptors soon learned their trade and at their best produced attractive works in a provincial idiom, often for votive purposes. Many cruder works were also executed whose interest lies in the proof they afford that the conventions of the classical world had penetrated even to the lower classes. Mosaic floors, found in towns and villas, were at first, as at Fishbourne, laid by imported craftsmen. But there is evidence that by the middle of the 2nd century a local firm was at work at Colchester and Verulamium, and in the 4th century a number of local mosaic workshops can be recognized by their styles. One of the most skilled of these was based in Cirencester.
Roman civilization thus took root in Britain; its growth was more obvious in urban circles than among the peasants and weakest in the resistant highland zone. It was a provincial version of Roman culture, but one with recognizably British traits. The decline of Roman rule
