Ogygie is an island mentioned in Homer's Odyssey, as the home of the nymph Calypso, the daughter of the Titan Atlas, also known as Atlantis in ancient Greek. In Homer's Odyssey Calypso detained Odysseus on Ogygie for 7 years and kept him from returning to his home of Ithaca, wanting to marry him. Athena complained about Calypso's actions to Zeus, who sent the messenger Hermes to Ogygie to order Calypso to release Odysseus. Hermes is Odysseus's great grandfather on his mother's side, through Autolycos. Calypso finally, though reluctantly, instructed Odysseus to build a small raft, gave him food and wine, and let him depart the island.
