The Roman cities of Anatolia, with their fertile farmland and extensive trade networks, become the richest in the empire. A vast road system marked by milestones and many new bridges is in place by the end of the first century A.D. throughout Anatolia and remains in good repair for about 300 years. A.D. Christianity transforms the vocabulary of artistic expression, including new subjects for representation and new media such as church architecture. In the first century, Saint Paul introduces Christianity into Anatolia, where it becomes a recognized religion in the early fourth century. The political situation in the area of the Southern Caucasus is in a state of flux for several centuries as the Roman and then Byzantine empires fight with the Parthian and Sasanian empires for control of the Near East.
Independent states exist intermittently in Georgia, Armenia, and Azerbaijan.
An earthquake levels twelve cities in western Anatolia, including Sardis. The rebuilding of these cities under the direction of the Roman emperor Tiberius results in their transformation from Greek or Hellenistic to Roman plans, including Roman architectural forms such as the hippodrome and the monumental arch, as well as long, broad main streets. Roman architecture and city planning are not restricted to these rebuilt cities, but are introduced in many other cities in Anatolia and the Southern Caucasus, as well as elsewhere in the empire. A.D. Catacomb burials may be those of the Alans, a tribal group new to the Caucasus. The burials contain ceramics similar to those of the urban centers to the south, as well as iron weapons.
