"So then,
royal son of Laertes, Odysseus, man of exploits,
still eager to leave at once and hurry back
to your own home, your beloved native land?
Good luck to you, even so. Farewell!
But if you only knew, down deep, what pains
are fated to fill your cup before you reach that shore,
you’d stay right here, preside in our house with me
and be immortal."

– Homer

The Odyssey, Book 5, lines 223-231. Begging Odysseus to stay with her, Calypso tries to seduce him with the offer of immortality and promise to save him from future woes. His journey back to his homeland will be filled with pain, she prophesies. This foreshadows that the rest of Odysseus’ journey to Ithaca without his crew will be a very difficult one.
