In Greek mythology, Hypsipyle was a queen of Lemnos, and the daughter of King Thoas of Lemnos, and the granddaughter of Dionysus and Ariadne. When the women of Lemnos killed all the males on the island, Hypsipyle saved her father Thoas. She ruled Lemnos when the Argonauts visited the island, and had two sons by Jason, the leader of the Argonauts. Later the women of Lemnos discovered that Thoas had been saved by Hypsipyle and she was sold as a slave to Lycurgus, the king of Nemea, where she became the nurse of the king's infant son Opheltes, who was killed by a serpent while in her care. She is eventually freed from her servitude by her sons.
