What was the name of the one eyed monster blinded by Odysseus?

The one-eyed monster blinded by Odysseus is named Polyphemus. He is a Cyclops and the son of Poseidon in Homer's epic, "The Odyssey." Odysseus and his men escape from Polyphemus' cave by blinding him and then cleverly identifying himself as "Nobody," which prevents the other Cyclopes from coming to his aid.
