Leucothea gives Odysseus a veil after Poseidon wrecks his raft. In Homer's Odyssey, she is the sea goddess who appears when Odysseus is struggling in the water after leaving Calypso's island.
Leucothea tells him to wrap her immortal veil around himself, abandon the wreckage, and swim toward the land of the Phaeacians. Odysseus initially distrusts the advice, fearing another divine trap, but he follows it when the storm worsens. The veil helps preserve him as he battles the sea, and he eventually reaches Scheria, the Phaeacian homeland.
Homer identifies Leucothea with Ino, a mortal woman transformed into a goddess after tragedy overtakes her family. This makes her different from Amphitrite, Poseidon's wife, who is a major sea goddess but does not perform this rescue. The episode also shows the divided divine world of the poem: Poseidon persecutes Odysseus, while another sea-associated deity intervenes on his behalf.
