"Hundred-Handed One
Wikipedia EN
In Greek mythology, the Hecatoncheires (Greek: Ἑκατόγχειρες, 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, each with fifty heads and one hundred arms. In the standard tradition they were the offspring of Uranus (Sky) and of Gaia (Earth), and helped Zeus and the Olympians to overthrow the Titans in the Titanomachy.
The three Hundred-Handers were named Cottus, Briareus and Gyges. Cottus (Κόττος) is a common Thracian name, and is perhaps related to the name of the Thracian goddess Kotys. The name Briareus (Βριάρεως) was probably formed from the Greek βριαρός meaning "strong". Hesiod's Theogony also calls him "Obriareus". The name Gyges is possibly related to the mythical Attic king Ogyges (Ὠγύγης). "Gyes", rather than Gyges, is found in some texts.
