This apse mosaic pictures Christ, the apostles, and Praxedes (Prassedes) and Pudentiana (Pudenziana) with crowns. The entire apse depicts scenes from Revelation- victorious saints, apostles robed, four-winged creatures, the four Gospel writers, and many other persons and animals. In the center of the main apse, over the altar, the hand of God points down to Christ Pantocrator, who stands centered, with Peter and Paul on either side of him. The two apostles each stand next to a woman, with an arm around her shoulders—Peter with Pudentiana and Paul with Praxedes. The women hold their crowns, emblematic of martyrdom. Though the sisters were not executed for their faith, they risked their lives to serve martyrs. On the far ends of the apse are Pope Paschal, with the square nimbus indicating him as alive when the mosaic was created, and a deacon opposite him next to Pudenziana. Under the curved base of the mosaic we see a line of sheep, with the Lamb of God at center, underneath the image of Christ Pantocrator.
