Apollo is one of the twelve deities of Olympus, the son of Zeus and Leto, and twin brother to Artemis. He is generally recognized as the god of light (or the sun), plague and healing, music, archery, and prophecy, especially at Delphi. His main iconic identifiers are the laurel wreath around his head, the lyre, and the bow. Apollo is usually described as the most “Greek” of the Greek gods, because he is the idealized form of kouros, a young man in perfected beauty and grace.
