Odysseus was actually being held captive by Circe and Calypso. During his captivity, he longed for home. In Greek mythology, Calypso was a nymph.
Odysseus was warned about the danger of the sirens' song leading sailors to their deaths. He was cautious and instructed his men to plug their ears with beeswax and tie him to the mast of the ship to resist their enchanting song. Odysseus wanted to hear the sirens' song but also wanted to ensure the safety of his crew.
Calypso took Odyssey in on her island, Ortygia and had him be her lover for seven years until Athena asked Zeus to free Odyssey. So Zeus sent Hermes to give Calypso the message and Calypso release Odyssey and helped him build his boat to leave Ortygia.
We learn that Calypso loves Odysseus and will do ANYTHING to keep him with her.
