Osiris was the husband of Isis, and the Egyptian god of the Underworld and the dead. In Greek mythology he was the son of Zeus and Niobe, and according to Plutarch he was murdered by his brother Typhon. The Greeks, too, linked him with Dionysus.

His name appears to originate from the Egyptian city of Busiris that also gave the name of the king who in Greek mythology was regarded as the son of Poseidon and Lysianassa. Both Osiris and Busiris are names that have been popularly thought to mean, without much foundation, 'many-eyed'.
