Eurylochus serves as a foil for Odysseus’ character because
he is a coward whereas Odysseus is brave.
This is bests seen when he lands in Circe’s island. He takes charge of half the crew to
investigate the island while Odysseus and the others stay on the boat. When he suspects that there is danger, he
stays behind and lets the others explore the island where the meet Circe who
turns them into pigs. Eventually the men
are saved by Odysseus with the help of Hermes.
