In the upper clerestory sections, above the processional figures, there are figures of saints between all the windows. Of perhaps the greatest interest in the church are the very top mosaics above the windows, with depictions of Biblical scenes - interesting thing is, they are Arian in origin! They were so high up, and basically were non-heretical in depiction, so they were left alone by the orthodox when they came into possession of the church. These two scenes at the top are of the paralytic being lowered to Christ and of the Last Judgment (separation of the sheep from the goats). In between the scenes are decorative blocks, not sure what these are of.
