Odysseus boasting of blinding Cyclops and Cyclops seeking revenge.

After the Cyclops finds Odysseus and his men in his cave, Odysseus tells him his name is Nohbody. The Cyclops takes him at his word and begins to call Odysseus Nohbody. This is very clever because when Odysseus escapes, the Cyclops calls for help. The other Cyclops on the island ask about the person who hurt him and he answers, "Nohbody." However, Odysseus is so proud of himself that when he feels he is beyond the range of the Cyclops, he calls back revealing his real name. This in turn results in the Cyclops asking his father to seek revenge on Odysseus. Poseidon, the Cyclops' father, keeps Odysseus from being able to return home.
