Ten years of war and years of wandering have left Odysseus with almost no crew. A storm drives his ship to an uncharted island, where the nymph Calypso offers shelter — and wants him for herself. He refuses: his heart belongs to his wife, Penelope.
So Calypso has her servant Corina brew a potion to erase Penelope from his memory. Corina quietly defies her, sending Penelope into his dreams instead, to give him the strength to resist. When Odysseus announces he is leaving, Calypso stops asking.
