What is the name of the Cyclops blinded by Odysseus?

The Cyclops blinded by Odysseus is Polyphemus.

Polyphemus is the one-eyed Cyclops at the center of one of the Odyssey’s most famous episodes. Odysseus and his companions enter Polyphemus’s cave, expecting hospitality, but the giant traps them by rolling a huge stone across the entrance and begins eating the men.

Odysseus eventually gives Polyphemus strong wine and claims that his name is “Nobody.” Once the Cyclops falls asleep, Odysseus and his surviving men heat a sharpened wooden stake in the fire and drive it into Polyphemus’s single eye. When the other Cyclopes hear his cries, Polyphemus says that “Nobody” is hurting him, so they assume no one is attacking him and do not help.

The Greeks escape by tying themselves beneath Polyphemus’s sheep. Odysseus later boasts about his true identity, allowing Polyphemus to call upon his father, Poseidon, for revenge. That prayer helps explain why Odysseus’s journey home becomes so difficult. Arges, Steropes, and Brontes are different Cyclopes in Greek mythology, associated especially with thunderbolts and divine craftsmanship.
