The wall-painting of Saint George on horseback, in the type of Diasorites, is placed in the conch of the south apse of the narthex and it is dated to the early thirteenth century.
As stated by the inscription, Nikiphorus Kallias, a farrier of horses, was the donor of the fresco. The choice of Saint George was not only due to the fact that he was famous among other saints, but also due to the connection of his patron’s occupation and his characteristic as a protector of cattle.
Saint George stands out as one of the most elaborated frescoes in Asinou church reflecting the wealth of the donor. He is depicted in lavish materials such as gold, silver, cinnabar and the distinctive blue, lapis lazuli. The set in which he was portrayed is a spare landscape while he is riding eastward to the bema with his bright red cape flowing. Being chief of the elite corps of saint stratilate, George wears military blue and ginger colour garments embellished with pearls and gems and an imperial crown, particular features of holy warriors. Behind him is his splendid round shield painted with stars and medallions and adorned with pearls around a cross supported with a crescent moon. Lastly, the horse occupies a large surface of the fresco and is depicted in an active position.
