(Εὐρύλοχος), one of the companions of Odysseus in his wanderings. He was the only one that escaped from the house of Circe, while his friends were metamorphosed into swine; and when Odysseus went to the lower world, Eurylochus and Perimedes performed the prescribed sacrifices. It was on his advice that the companions of Odysseus carried off some of the oxen of Helios. (Hom. Od. 10.203, &c., 11.23, &c., 12.339, &c.) Another personage of the same name is mentioned among the sons of Aegyptus. (Apollod. ii 1.5.)
