The clipei of the choir’s four ogival arches feature images of angels, kings and prophets. Arranged in a crescendo, they tell the story of salvation along with the rest of the mosaic cycle. The first arch shows representations of the Archangel Michael and the Archangel Gabriel with the tondo of Divine Wisdom in the upper centre. In the intrados of the arch, there are depictions of Kings Obed, Jesse, Solomon, David and Rehoboam. In the central sub-arch, there are depictions of the king and priest Melchizedek, as well as the other patriarchs Noah and Enoch, Abraham and Isaac, Jacob and Judah.
