He was the father to many mythological creatures which included a flying horse named Pegasus, the Minotaur (a creature with the head of a bull on the body of a man), and numerous others such as hippocamps (horses with mermaid-like tails) and golden deer among others. Poseidon was fathered by Kronos with Rheia (the wife of Oceanus). He married Amphitrite, a Nereid, and they had many children including Triton and Rhode. He is often seen with his brother/nephew Zeus who became ruler of Olympus after deposing their father, and his other brothers Hades and Horkos (or Horkhos). When Horkhos wouldn’t release the imprisoned giants he was punished for this crime against humanity by having an eagle carry off one of his eyes. He also held sway over Demeter and Dionysus.
