Jesus in the Garden of Gethsemane
Church of Sant'Apollinare Nuovo, Ravenna
In the gospels, after the Last Supper Jesus takes his apostles (minus Judas) to pray in the Garden of Gethsemane (Mt 26:36-46, Mk 14:32-42, Lk 22:39-46, Jn 18:1). Here we see him in orant position – that is, with his arms extended in prayer. The gospel passages show Jesus struggling with sorrow and dread, but in the mosaic he prays calmly in a pastoral setting. This may be because the artist or sponsor wanted to avoid possible Arian implications of a fearful Jesus.1
The image is also kinder to the apostles than the gospel passages, which say they fell asleep while Jesus was praying in his agony. Here we see them engaged in some sort of lively discussion.
This is one of the 13 mosaics of the Passion and Resurrection of Christ along the right wall of the nave. It can be identified as Gethsemane because there are only 11 apostles and because in the series on the wall it is between the Last Supper and the Kiss of Judas. The two figures at Jesus' feet are St. Peter and St. Andrew. The latter has the same head of wild, rounded hair that he wears in the scenes of the Calling of Andrew and Peter and the Miracle of the Loaves and Fishes. Following tradition, the mosaic gives Peter a short, square beard. Throughout the mosaics on both walls, he always has gray hair, presumably a sign of his "senior" status.
