Book 1
1.2
After these, Earth bore him the Cyclopes, to wit, Arges, Steropes, Brontes,Compare Hes. Th. 139ff. of whom each had one eye on his forehead. But them Sky bound and cast into Tartarus, a gloomy place in Hades as far distant from earth as earth is distant from the sky.Compare Hes. Th. 617ff. and for the description of Tartarus, Hes. Th. 717ff. According to Hesiod, a brazen anvil would take nine days and nights to fall from heaven to earth, and nine days and nights to fall from earth to Tartarus.
1.3
And again he begat children by Earth, to wit, the Titans as they are named: Ocean, Coeus, Hyperion, Crius, Iapetus, and, youngest of all, Cronus; also daughters, the Titanides as they are called: Tethys, Rhea, Themis, Mnemosyne, Phoebe, Dione, Thia.Compare Hes. Th. 132ff. who agrees in describing Cronus as the youngest of the brood. As Zeus, who succeeded his father Cronus on the heavenly throne, was likewise the youngest of his family (Hes. Th. 453ff.), we may conjecture that among the ancient Greeks or their ancestors inheritance was at one time regulated by the custom of ultimogeniture or the succession of the youngest, as to which see Folk-Lore in the Old Testament, i.429ff. In the secluded highlands of Arcadia, where ancient customs and traditions lingered long, King Lycaon is said to have been succeeded by his youngest son. See Apollod. 3.8.1.
