He spends one last night with Circe and she describes the obstacles he will face on his voyage home
They approach the island of the lovely Sirens, and Odysseus, as instructed by Circe, plugs his men’s ears with beeswax and has them bind him to the mast of the ship.
Keep the beeswax in your ears, men
Once they have passed the Sirens' island, Odysseus and his men navigated the straits between Scylla and Charybdis. Scylla is a six-headed monster who, when ships pass, swallows one sailor for each head.
Odysseus next comes to Thrinacia, the island of the Sun. He wants to avoid it entirely, but the outspoken Eurylochus persuades him to let his beleaguered crew rest there.
Eurylochus persuades the other crew members to disobey Odysseus and slaughter the cattle of the Sun. They do so one afternoon as Odysseus sleeps; when the Sun finds out, he asks Zeus to punish Odysseus and his men.
