Odysseus is recognized for his cunning, intelligence, and inventiveness. However, at times, his trickery and cleverness have led to more challenges than advantages. A prime example is when he and his men find themselves trapped by the Cyclops, Polyphemus. He deceives the Cyclops by stating his name is "nobody", allowing him to blind the Cyclops who then calls out that "nobody" hurt him. The other Cyclopes believe he has lost his sanity. Although Odysseus and his crew succeed in escaping, he cannot resist revealing his true identity. Polyphemus then appeals to his father, Poseidon, the sea god, for vengeance against Odysseus, initiating a string of misfortunes on his return journey home.
