Dome Mosaic: Baptism of Christ (Detail)

The Baptism of Christ by John the Baptist in the Jordan River. Detail of dome mosaic in the Battistero Neoniano (Orthodox Baptistery) in Ravenna, dating from 451-75. The right arm of John the Baptist, the dove, and Christ's head are 18th-century restorations and the dish was a controversial addition of the 19th century, but the rest is original.
