after escaping from the sea, and the death of his men, odysseus comes to the island ogygia. on this island lives the nymph calypso, and odysseus stayed with her for seven years. but then the god hermes came and told her that the gods said that she had to let odysseus go. calypso promised odysseus immortality (that he would live forever) if he stayed, but he wanted to go back to his wife penelope. so odysseus built a raft and left her.
