 There are in Plato identifiable traditional myths, such as the story of Gyges (Republic 359d–360b), the myth of Phaethon (Timaeus 22c7) or that of the Amazons (Laws 804e4). Sometimes he modifies them, to a greater or lesser extent, while other times he combines them—this is the case, for instance, of the Noble Lie (Republic 414b–415d), which is a combination of the Cadmeian myth of autochthony and the Hesiodic myth of ages. There are also in Plato myths that are his own, such as the myth of Er (Republic 621b8) or the myth of Atlantis (Timaeus 26e4). Many of the myths Plato invented feature characters and motifs taken from traditional mythology (such as the Isles of the Blessed or the judgment after death), and sometimes it is difficult to distinguish his own mythological motifs from the traditional ones. The majority of the myths he invents preface or follow a philosophical argument: the Gorgias myth (523a–527a), the myth of the androgyne (Symposium 189d–193d), the Phaedo myth (107c–115a), the myth of Er (Republic 614a–621d), the myth of the winged soul (Phaedrus 246a–249d), the myth of Theuth (Phaedrus 274c–275e), the cosmological myth of the Statesman (268–274e), the Atlantis myth (Timaeus 21e–26d, Critias), the Laws myth (903b–905b).
