Both Hesiod and Homer locate Oceanus at the ends of the earth, near Tartarus, in the "Theogony", or near Elysium, in the "Iliad", and in the "Odyssey", has to be crossed in order to reach the "dank house of Hades". And for both Hesiod and Homer, Oceanus seems to have marked a boundary beyond which the cosmos became more fantastical. The "Theogony" has such fabulous creatures as the Hesperides, with their golden apples, the three-headed giant Geryon, and the snake-haired Gorgons, all residing "beyond glorious Ocean". While Homer located such exotic tribes as the Cimmerians, the Aethiopians, and the Pygmies as living nearby Oceanus.
