The Greek God's Family Tree is difficult to reconstruct. The data came from various sources, including mythology texts and paintings. Cronus (Kronos) is the most ancient god in the Greek Gods Family Tree. He was a Titan who ruled over the other Titans before being castrated by Zeus and banished from Mount Olympus, where he was known as Saturn (Saturn). Cronus' offspring were known as Olympians or Titans. Zeus (Jupiter), Poseidon (Neptune), Hades (Pluto), Hera (Juno), Ceres (Demeter), Apollo (Apollo), Artemis (Diana), and Hephaestus are among them (Vulcan).
