In Greek mythology, Eurylochus (/jəˈrɪləkəs/; Ancient Greek: Εὐρύλοχος Eurúlokhos) appears in Homer's Odyssey as second-in-command of Odysseus' ship during the return to Ithaca after the Trojan War.[1][2] He is portrayed as an unpleasant, cowardly individual who undermines Odysseus and stirs up trouble.
