Hesiod and Parmenides
Note from The Dialogue Of Apollodorus by Plato

Hesiod's Theogony describes such events, the mutilation of Uranus by Cronus, the imprisonment of the Cyclopes and hundred-armed giants, Cronus devouring his children, the war between Zeus and the Titans. There is no such reference in the extant fragments of Parmenides, and the reading of his name here has been suspected.
