Which Byzantine church in Ravenna was built by Bishop Ecclesius and dedicated in 548?

The Basilica of San Vitale in Ravenna was begun under Bishop Ecclesius and consecrated in 548.

Construction started during Ostrogothic rule and was completed after the Byzantine conquest of Ravenna. The church became famous for its richly colored marble revetment and sixth-century mosaics, including imperial panels showing Justinian and Theodora with their attendants.

Its octagonal central plan, gallery, and domed interior demonstrate how late antique and Byzantine design could combine ceremonial space with complex structural geometry. San Vitale is therefore central to the study of Byzantine architecture in Italy, even though it stands outside Constantinople.

Ecclesius initiated the project, but Bishop Maximianus oversaw its completion and dedication. That distinction explains why sources connect the basilica with both bishops.
