In Byzantine tradition, there is a unique vestige of the Iconoclastic art within the church. The apse semidome and the bema arch are covered with mosaics.[3] There are also the frescoes which can be found on the south side aisle.[4] These mosaics date back to about the 8th century. This was during the time of the earthquake which most of the upper parts of the church can date back to.[5] There is also a mosaic of a cross, which is outlined in black with a gold background.[3] The ends are flared along with having teardrop shapes at the end. This extends around the base of the semidome.[3] The cross was put in during the reconstruction by Constantine V, which was during the Iconoclastic years.[4] On the bema arch there is an inscription of Psalm 64 verses 4-5 on the inner sider, and then on the outer side there is an inscription of Amos 6 verse 6. There is evidence of alterations on these inscriptions as well.[3] The inscriptions detail a praise to the church as it is the house of the lord.[6] The verses, especially the Psalm, were used as inspiration for some of the mosaics in Hagia Sophia.[6]
