In the preceding chapter I traced the basis on which Xenocrates, Plato’s second successor as head of the Academy, created the original textual canon for building a Platonic system. It emerged that his authoritative Platonic texts were two myths – the creation myth of the Timaeus, and the Phaedrus’ mythical travelogue about the destiny of eternal souls. The latter passage, I argued, was so canonical as to determine, on occasion, how even the former should be interpreted.
