Theodosian

Refers to the style and period in the eastern Roman Empire surrounding the rule of Theodosius I (379-395 CE) through that of his grandson Theodosius II (408-450 CE). The style of this period is driven by the vigorous suppression of paganism and Arianism by Theodosius I, the emphasis on scholarly pursuits and the Theodosian Code of Law of Theodosius II, and the building campaigns of both emperors, including the erection of walls around Constantinople.
