Odysseus and his crew barely leave Aeaea after a year. Circe advises him to watch out for the island of sirens. They approach the dangerous sirens. As Circe advised, Odysseus and his men clog their ears with beeswax so they don't hear their seductive voices. The sirens' song is so alluring, Odysseus almost took off his beeswax, but his men pulled himself together and left the island of sirens. But they encountered a new problem. They encounter the Scylla and the Charybdis. As advised by Circe, Odysseus holds his the lowest sail on a square-rigged mast tight against the cliffs of Scylla's lair. He and his men stare at Charybdis on the other side of the channel, the heads of Scylla dive down and eats six of the sailors as they escape.
