In the center, Christ in a gold tunic outlined in red, accompanied by two angels, is venerated by two queues of apostles and saints; to the left, the first two are the Virgin Mary and St John the Baptist, and to the right the first is St Praxedis. At the ends of the queues are Moses and Elijah. On the right, next to the prophet, is an angel in a red tunic holding a book and a rod. The underside of the arch is Paschal's monogram at the keystone.
