Apollo on a Kios hemidrachm
Athena's brother and Zeus' son, Apollo was God of light, reason, inspiration, prophecy and oracles, healing and song, and also protector of flocks and herds. He was later further identified with the sun, and was to Constantine the Great's a kind of "pagan giude" during his transition to the world of Christianity. His youthful bust or figure are frequent themes of Greek coin issues, and his main attrubutes include the lyre, bow and spear, and tripod - the latter signifying the Delphic oracle, located in one of his two most famous sanctuaries.
