What giants had only one eye?

The story behind the answer

Cyclopes are the one‑eyed giants of Greek myth; their name comes from kyklos (circle) + ops (eye), literally “round‑eye.” Famous Cyclopes include Polyphemus, who traps Odysseus in Homer’s Odyssey, and the elder trio—Brontes, Steropes, and Arges—master smiths who forged Zeus’s thunderbolts. Their single eye is their defining trait, making Cyclopes the correct answer.

To remember: think “cycle” as a single circle—one big eye. Contrast helps too: Titans are an older generation of powerful gods, not one‑eyed; Gorgons (like Medusa) have snake hair and a petrifying gaze; Ogres are from later European folklore, not classical Greek myth.
