Greek monsters

Hyperion was the titan god of light. Hyperion's parents were Ouranos the heaven and Gaia the Earth. Hyperion, Krios, Koios and Iapetos were placed at the four corners of the world. They held their father tight while Kronos castrated him with a sickle. These four Titanes holds heaven and earth apart, or the entire universe. Hyperion was defeated by Zeus, and threw Hyperion into the deep hole of Tartaros. So Hyperion who used to held the heavens turned to prisoners of the entire universe. Hyperion married his sister Theia, and became the father of Helios, Selene, and Eos.
