Carrello
The decoration of the Dark Church shows that the master painter has first divided the vertical surface into two sections by a thick brownish band between narrower white stripes which encircle the whole interior. After this he surrounded each piece of the field in the same way and probably decided the registers for each large-scale saint figure, martyr or prophet. The surviving examples both in Cappadocia and other regions of the empire show that military saints had become very popular during the Middle Byzantine period. In order not to confuse the register reserved for each saint he might have scribbled the saint's name or initials on the surface of the plaster.
