 On the philosophical use of myth before Plato there are a number of good studies, notably Morgan 2000. There is, however, little on the philosophical use of myth in the Platonist tradition. Of Plato’s immediate successors in the Academy, Speusippus, Xenocrates and Heraclides of Pontus composed both dialogues and philosophical treatises. But, with one exception, none of these seems to have used myths as Plato did. The exception is Heraclides, who wrote various dialogues—such as On the Things in Hades, Zoroastres and Abaris—involving mythical stories and mythical, or semi-mythical, figures. In the later Platonist tradition—with the exception of Cicero and Plutarch—there is not much evidence that Plato’s philosophical use of myths was an accepted practice. In the Neoplatonic tradition various Platonic myths became the subject of elaborate allegorization. Porphyry, Proclus, Damascius and Olympiodorus gave allegorical interpretations of a number of Platonic myths, such as the Phaedo and Gorgias eschatological myths, or the myth of Atlantis.
