| Whether the astronomy of the Timaeus had any significant influence on Eudoxus’ theory of homocentric spheres is a matter of contention. Some commentators deny any such influence. Here I argue for a view of the Timaeus’ astronomy, and of Eudoxus’ astronomy, whereby Eudoxus’ work was as much a natural development of the Timaeus as Callippus’ work was of Eudoxus. I also argue for an important interpretative principle. This is that Plato, Eudoxus and Callippus could not account for all the phenomena they were aware of, and were aware of that fact. If the Timaeus presents a prototype, Eudoxus can then be seen to develop this astronomy, making the model more sophisticated and complex while staying within the cosmological principles, and attempting to solve the key problems which were left unsolved by the Timaeus model. He does this in much the same way as Callippus made Eudoxus’ model more complex and sophisticated, and attempted to solve the leading problems in that model. I also consider some further objections to a significant interaction between Plato and Eudoxus, based on supposed philosophical differences, dating, and the evidence of later commentators. I conclude that these provide no significant obstacle to considering there to be a fruitful liaison between Plato and Eudoxus. [introduction, p. 5] |

| The nature of the receptacle, presented at Timaeus 48e-53b, is controversial. It is unclear whether the receptacle is supposed to be matter, or whether it is supposed to be space, or whether it is in some way both matter and space. Plato seems to intend some reform of the way in which we refer to the phenomena, but the nature of that reform is far from clear.1 Can the evidence of Aristotle help us here? Aristotle and some of his commentators have some interesting and significant things to say about the receptacle and its contents, more perhaps than is generally recognised. [introduction, p. 29] |
