Calypso fell in love with Odysseus and offered him immortality if he stayed with her, but he longed to return to his home in Ithaca. Eventually, the god Hermes intervened, delivering a message from Zeus that ordered Calypso to let Odysseus go. Heartbroken, she helped him build a raft and provided him with supplies for his journey. Calypso's story highlights themes of love, longing, and the struggle between desire and duty.
