The ideal of the kouros (a beardless, athletic youth), Apollo has been variously recognized as a god of music, truth and prophecy, healing, the sun and light, plague, poetry, and more. Apollo is the son of Zeus and Leto, and has a twin sister, the chaste huntress Artemis.Apollo is known in Greek-influenced Etruscan mythology as Apulu. As the patron of Delphi (Pythian Apollo), Apollo was an oracular god—the prophetic deity of the Delphic Oracle.n the Iliad, Apollo is the healer under the gods, but he is also the bringer of disease and death with his arrows, similar to the function of the terrible Vedic god of disease Rudra. He sends a terrible plague (λοιμός) to the Achaeans.
