Also known as Somnus, Hypnos was the god of rest, and a twin brother of Thanatos. His influence extended beyond men, to gods as well, the deities welcoming rest and refreshment as much as anyone. He lived in deep subterranean darkness near the entrance to Tartaros with his brother, and was styled many different ways:as a youth holding a poppy or a horn, from which sleep trickled down on those reposing;as a child;or as an aged, bearded man. On his head were the wings of a hawk or a night bird, and beside him frequently a lizard. He was looked on as a favourite of the Muses, because of the dreams he was supposed to communicate to men.
