Timaeus and Eternal Recurrence

One of the best-known formulations of the Timaeus is that Time is "the moving image of eternity". Receiving less attention has been an assertion that appears a little later in the same paragraph: "These are the forms of time, which imitates eternity and revolves according to a law of number." Now, though Plato does not seem to develop the notion further, and he has generally not been interpreted as such, the use of 'revolve' in the passage suggests that he is there espousing a circular theory of Time. If so, then the only difference between that proposal and Nietzsche's formulation that 'Eternal Recurrence is the closest approximation of Becoming to Being' is that Plato also posits the actual existence of unchanging Being. Accordingly, what is sometimes characterized as Nietzsche's 'overturning' of Platonism is, in this respect at least, not wanton destruction, as it is sometimes interpreted as, but precise inversion--an inversion of Plato's thesis that Time is derived from Eternity, with one that Eternity is an hypostasization of Time. On this reading of the Timaeus, Time, in both theories, is Eternal Recurrence.
