After a while, the Argonauts pass by Lemnos on their way back from Colchis. Although the women try to prevent them from disembarking, the Argonauts invade the island and, in a mass rape, father a new population of Lemnians. Hypsipyle is raped by their leader, Jason, and gives birth to two sons. In spite of their offspring, the Argonauts decide to leave the island. When rumour of Thoas' survival reaches the island, Hypsipyle is forced to flee. Apprehended by pirates, the princess is sold to Lycurgus, king of Nemea who makes her a nurse to his infant son Opheltes.
