Bia’s Alliance with Zeus in the Titanomachy

Zeus called the gods to aid him in his war against the Titans. Styx came first to Olympus. She was the eldest daughter of Oceanus and Tethys, and her children, Bia, Nike, Kratos, and Zelos, joined her. Bia embodied force and violent compulsion. Nike represented victory, Kratos strength, and Zelos rivalry.

The conflict became the Titanomachy, a ten-year war between Zeus and the Titans. The Titans held their stronghold on Mount Othrys, while Zeus and his allies fought from Olympus. The Cyclopes and the Hecatoncheires also supported Zeus. The Cyclopes had forged his thunderbolts, along with Poseidon’s trident and Hades’ helmet of darkness. These weapons later helped break the deadlock.

Zeus and his brothers and sisters, aided by the Hecatoncheires and Cyclopes, overthrew Cronus and the Titans. Many of the defeated Titans were confined in Tartarus. Menoetius was struck by Zeus’s thunderbolt and hurled there during the battle. Oceanus, Helios, Atlas, Prometheus, Epimetheus, and Menoetius are also named among those who escaped, although the accounts differ concerning Menoetius.

Zeus rewarded Styx and her children for their help. Bia, Nike, Kratos, and Zelos became his constant companions and held a permanent place beside his throne. Zeus also made the waters of Styx the witness of oaths. In one account, these waters flowed from a rock in Hades. Styx’s journey before she came to Olympus is less clear, though Hesiod describes her as a branch of Oceanus flowing beneath the earth through black night.
