In Greek mythology, the Hecatoncheires (/ˈhɛkətɒŋkəriz/; Greek: Ἑκατόγχειρες, translit. 'Hekatónkheires', lit. "Hundred-Handed Ones"), or Hundred-Handers, also called the Centimanes, (/ˈsɛntɪmeɪnz/; Latin: Centimani), named Cottus, Briareus (or Aegaeon) and Gyges (or Gyes), were three monstrous giants, of enormous size and strength, with fifty heads and one hundred arms. In the standard tradition they were the offspring of Uranus (Sky) and Gaia (Earth), who helped Zeus and the Olympians overthrow the Titans.
The Hundred-Handers, Cottus, Briareus and Gyges, were three monstrous giants, of enormous size and strength, with fifty heads and one hundred arms. They were among the eighteen offspring of Uranus (Sky) and Gaia (Earth), which also included the twelve Titans, and the three one-eyed Cyclopes. According to the Theogony of Hesiod, they were the last of these children of Uranus to be born, while according to the mythographer Apollodorus they were the first. In the Hesiodic tradition, they played a key role in the Greek succession myth, which told how the Titan Cronus overthrew his father Uranus, and how in turn Zeus overthrew Cronus and his fellow Titans, and how Zeus was eventually established as the final and permanent ruler of the cosmos.
