The defining feature of the Cyclopes in Greek myths is their single eye in the center of the forehead. These one-eyed giants are known for their immense strength and craftsmanship, particularly in forging powerful weapons for gods like Zeus. Cyclopes represent the raw, untamed forces of nature and are often portrayed as solitary figures, emphasizing themes of isolation and the relationship between creators and their creations. Their existence reflects the interplay between power and the divine.
