The island that I washed up on is actually called Ogygia, the home of Calypso, the nymph who found me on the beach. She gave me immortality in exchange for my love which I accepted at the time. However, after spending seven years with Calypso I still wanted to get home to Ithaca. When I asked her to leave, she refused to let me go until Hermes came with a message from Zeus to release me. So I set about building a raft to carry me home and left when it was finished to complete my journey.
