HAGIA SOPHIA: Hagia Sophia also contains several fine Medieval frescos. This image of Christ enthroned is painted in the lunette over the imperial doorway leading into the interior of the church. In the circles on either side are busts Mary and the Archangel Gabriel. The figure on the left is often identified as Leo VI the Wise (886-912) bowing before Christ. Such royal self-portraits were a way of glorifying the Emperor's power and wealth while simultaneously showing his piety, and were common in both the eastern and western churches.
