Altichiero da Verona
Scenes from the Life of St. George

1378-84
Fresco
Oratorio of St. George, Padua

In the upper register Saint George baptizes the King of Silena, whose daughter he saved from the dragon. The altar and apse in the background allude to the king's subsequent decision to build a church in honor of the Virgin and St. George.

In the main scene in the lower episode angels destroy the wheel on which the Prefect Dacian had intended to torture the saint. Bystanders bend and fall to get out of the way of the flying parts. The angels wear George's red cross on their shields and breastplates.

In the gallery on the left in the lower register, George baptizes the magician who had sought to poison him. In the gallery on the right, he declares his faith to Dacian.
