The Apse Mosaics of the Euphrasian Basilica. Detail: Saints James, Andrew, and Peter

6th century
Euphrasian Basilica, Poreč, Croatia

This detail is from above the vault of the main apse, directly to the left of Christ. Except in the case of Peter's keys, the attributes carried by the apostles appear to be determined by the design of the piece rather than any individual characteristics.
