 Some art historians see the style as coming from the tradition of Alexandria, from which no other painting on a similar scale remains.John Beckwith is somewhat less enthusiastic than some art historians, describing the frescos as "wholly competent" and worthy of comparison with 7th century works in Rome He believed the "drapery folds ... a complex series of angular ridges emphasized by highlights ... make a decidedly metallic impression, and betray the copyist, who foreshadows in a disturbing way tenth-century mannerisms".The Byzantinesque frescoes are located around the curved wall of the apse, and the inward surface of the arch between the apse and the main body of the church.
