Apollo
Apollo (Greek: Ἀπόλλων; Latin: Apollo) was one of the twelve Olympian gods of Greek and Roman mythology. He was considered the god of light, moral purity, healing and divination, as well as the patron of the arts and many oracle sites. In particular, the Oracle of Delphi, the most important oracle site of antiquity, was dedicated to him. As Phoibos (Greek Φοῖβος; Latin Phoebus "the shining one") he was equated with the sun god Helios, while his twin sister Artemis was equated with the moon goddess Semele or the Egyptian Isis. The origin of his name is uncertain. The Pythagoreans and Platonists, who particularly revered Apollo, interpreted his name as A-pollon (the "not-many" or meaning "the one", from ἀ- a- "not" and πολλόν pollón "much, very") and thus pointed to the highest, the absolute. This is also said to have been the subject of Plato's unwritten teaching.
