Briareus, also known as Aegaeon, is a figure from Greek mythology. He is one of the Hecatoncheires, a group of three giants who each had a hundred arms and fifty heads. Briareus is often associated with immense strength and was known for his role in the Titanomachy, the battle between the Titans and the Olympian gods. In the myths, Briareus was a loyal ally to the Olympians, helping them defeat the Titans. His formidable size and power made him a key figure in the conflict, and he was later entrusted with guarding the imprisoned Titans in the depths of Tartarus.
