Julian sacrifices to the Moon at Charroe. 1161.

This is one of a group of drawings by British artist and book illustrator Edward Francis Burney, depicting scenes from Greek and Roman history and mythology. The seated female figure is the Roman goddess, Diana, recognisable by her headdress. Like her Greek equivalent, Artemis, she was the goddess of hunting, the Moon and chastity. Emperor Julian practiced polytheism rather than Christianity, and is sacrificing to Diana in this image.
