This article examines the evidence for Germanic ‘Arianism’ in the exceptionally well preserved buildings and mosaics of Ravenna. Despite theological differences, Arian iconography appears to be almost identical to that of the ‘Catholics’ (e.g. in depictions of Christ in S. Apollinare Nuovo and the Arian Baptistery). Different attitudes to God the Son are only really apparent when supported by texts. However, there are clear material traces of Catholic triumphalism after the defeat of the Arian Goths; and we should not assume that there were no strongly held differences of view, just because the iconography of the two sects is so similar.
