Jesus Predicts Peter's Denial
Church of Sant'Apollinare Nuovo, Ravenna
This is one of the 13 mosaics of the Passion and Resurrection of Christ along the upper band of the right wall of the nave. Jesus predicts that Peter will deny knowing him "before the cock crows." In the mosaics, this scene comes after the trial before the Sanhedrin and before Peter's denials to the woman at the gate. In the gospels, it is at the Last Supper that Jesus predicts Peter's denial.1 Thus the artist has placed this episode a bit out of order so that the prediction can be contemplated side by side with the denial.
