Oceanus and Tethys, Cronus and Rhea, Themis, and Mnemosyne (i.e. the river gods, the Oceanids, the Olympians, the Horae, the Moirai, and the Muses) are not normally considered to be Titans, descendants of the other Titans, notably: Leto, Helios, Atlas, and Prometheus, are themselves sometimes referred to as Titans. Variations Passages in a section of the Iliad called the Deception of Zeus suggest the possibility that Homer knew of a tradition in which Oceanus and Tethys (rather than Uranus and Gaia, as in Hesiod) were the parents of the Titans. Twice Homer has Hera describe the pair as "Oceanus, from whom the gods are sprung, and mother Tethys", while in the same passage Hypnos describes Oceanus as "from whom they all are sprung". Plato, in his Timaeus, provides a genealogy (probably Orphic) which perhaps reflected an attempt to reconcile this apparent divergence between Homer and Hesiod, with Uranus and Gaia as the parents of Oceanus and Tethys, and Oceanus and Tethys as the parents of Cronus and Rhea "and all that go with them", plus Phorcys. In his Cratylus, Plato quotes Orpheus as saying that Oceanus and Tethys were "the first to marry", possibly also reflecting an Orphic theogony in which Oceanus and Tethys, rather than Uranus and Gaia, were the primeval parents. To Hesiod's twelve Titans, the mythographer Apollodorus, adds a thirteenth Titan, Dione, the mother of Aphrodite by Zeus. Plato's inclusion of Phorkys, apparently, as a Titan, and the mythographer Apollodorus's inclusion of Dione, suggests an Orphic tradition in which the canonical twelve Titans consisted of Hesiod's twelve with Phorkys and Dione taking the place of Oceanus and Tethys. The Roman mythographer Hyginus, in his somewhat confused genealogy, after listing as offspring of Aether (Upper Sky) and Earth (Gaia), Ocean [Oceanus], Themis, Tartarus, and Pontus, next lists "the Titans", followed by two of Hesiod's Hundred-Handers: Briareus and Gyges, one of Hesiod's three Cyclopes: Steropes, then continues his list with Atlas, Hyperion and Polus, Saturn [Cronus], Ops [Rhea], Moneta, Dione, and the three Furies: Alecto, Megaera, and Tisiphone. The geographer Pausanias, mentions seeing the image of a man in armor, who was supposed to be the Titan Anytos, who was said to have raised the Arcadian Despoina. Former gods The Titans, as a group, represent a pre-Olympian order. Hesiod uses the expression "the former gods" () in reference to the Titans. They were the banished gods, who were no
