The most famous Cyclops in Greek mythology, the son of Poseidon and the sea nymph Thoosa. The most notable myth involving Polyphemus is his appearance in Book IX of Homer's Odyssey: after Odysseus and his crew land on Polyphemus' island after escaping the Lotus-Eaters, Polyphemus eats two of Odysseus' crew, imprisons the rest in his cave, and eats four more before the survivors can escape. To escape, Odysseus gets Polyphemus drunk on wine and blinds the one-eyed giant with a stick; the next morning, Odysseus and his crew ride out of Polyphemus' cave, hiding underneath the Cyclops' sheep. When Polyphemus asks Odysseus' name, Odysseus responds 'No one' or 'No man' (translations vary), and Polyphemus prays to his father Poseidon to make Odysseus' journey home treacherous. In another myth, Polyphemus falls in love with the nymph Galatea, who in turn loves the human Acis. Polyphemus then kills Acis with a boulder out of jealousy.
