View looking up at the mosaic at the top of the eastern Apse. Although heavily reconstructed this is a relic of the old pre–fire of 1823 arch. It was originally executed in 1220.
In the center is the ascended Christ holding the Gospels and blessing in the Greek manner. Surrounding him are saints Peter, Andrew, Paul, and Luke. Below the seated Christ is a gem–studded cross and angels and apostles. In the upper left corner is the Virgin and Child, and in the upper right is Saint John blessing Pope John XXII.
