Theodora (c. 500 – 28 June 548), was empress of the Byzantine Empire and the wife of Emperor Justinian I. She was one of the most influential and powerful of the Byzantine empresses. Some sources mention her as empress regnant with Justinian I as her co-regent. Along with her husband, she is a saint in the Eastern Orthodox Church, commemorated on November 14.
This mosaic art of the Byzantine Empress is at the Basilica of San Vitale in Ravenna, Italy.
