Basilios Drakocheres is portrayed on the west respond of the south arch, under the monk Kallinikos. His face is turned eastward with his hands raised in prayer. His clothing, rolled hair and head garment resemble the Western clothing of the portrait of the donor of Saint Georgios Mahairemenos. Specifically, he wears a white cotte discerned from the white cuffs, a long dark blue coat and a white coif. The inscription reads: 'Prayer of the servant of God Basileios Drakocheres.'
