Hypnos is the god of sleep in Greek mythology. He is the son of Nyx and the twin brother of Thanatos, the god of death.
His sons are the Oneroi: Morpheus, Phobetor and Phantasos.
His Roman equivalent was Somnus. Hypnos was represented as a gentle young man, usually with wings attached to his temples or shoulders.
