Gyges was one of the three Hekatonkheires.

Early Life, Imprisonment, Release, and Re-Imprisonment

Gyges was the younger brother of the Titans and Cyclopes, a son of Gaea and Ouranos. Their father, who despised his offspring, jailed the Hekatonknieres in Tartarus, which the Elder Cyclopes had already been banished to. After defeating his father Ouranos, Kronos became the King of Mount Orthys and kept his promise of releasing the Elder Cyclopes and Hekatonknieres from Tartarus. In return, Gyges and his Hekatonkniere brothers, Cottus and Briares, built a magnificent black marble palace for Kronos on Mount Orthys. However, Kronos was later disgusted by all of the unbearable noise that the Hekatonkheires and Elder Cyclopes constantly made, as well as their revolting stench. Hence, Kronos, Hyperion and Atlas (the three most powerful Titans) chained all six of them up, and hurled them into Tartarus once again, this time guarded by Kampê, the most ferocious and terrifying monster in all of Tartarus that Kronos personally hired.

Release by Zeus

Many years later, after Zeus freed his elder Olympian siblings from Kronos' belly, they all ventured into Tartarus (with Hades' guidance). There, the Elder Cyclopes forged three incredibly powerful weapons for the gods: the Master Bolt (for Zeus), the Trident (for Poseidon), and the Helm of Darkness (for Hades). With these weapons, Zeus killed Kampê, and Poseidon shattered the chains of the Elder Cyclopes and Hekatonkheires.

The First Titanomachy

In return, all six of them fought on the side of the Olympians in the Titanomachy. Gyges had massive strength (and he was very proficient at hurling huge boulders), which greatly contributed to the Titans' ultimate defeat. At the final battle on Mount Orthys, all three Hekatonkheires were of great help, throwing so many rocks that the Titans thought that the mountain was falling apart. Since the Hekatonkheires had initially built Kronos' fortress on Mount Orthys, they knew exactly how to destroy it. In the subsequent final battle of the Titanomachy, the Olympians finally overwhelmed and defeated the Titans, including Kronos himself. In the aftermath of the battle, the Elder Cyclopes chained up all of the Titans, while the Hekatonkheires forced them to kneel before Zeus. Afterwards, Zeus offers the Hekatonkheires to return to Tartarus, this time as the jailers of the Titans, to which they readily agreed.


Sometime later, Gyges faded away, along with his brother Cottus, after mortals forgot his story, leaving only their brother Briares.

The Battle of the Labyrinth

Briares, his brother, mentioned Gyges while talking to Percy Jackson, Annabeth Chase, Grover Underwood, and Tyson. He said that, like his other brother, Cottus, he had faded.


  • Gyges' name means "The Big-Limbed".
  • As shown in Percy Jackson's Greek Gods, Gyges was freed from Tartarus by Poseidon, who smashed his chains with his new, mighty Trident.
  • Gyges and his Hekatonkniere brethren (along with the Elder Cyclops) built all of the palaces on both Mount Orthys and Mount Olympus.
  • Gyges only appears in Percy Jackson's Greek Gods and was mentioned in The Battle of the Labyrinth.
