1 Burnet, op. cit. p. 123, says; “This view that the planets had an orbital motion from west to east is attributed by Aetios ii. 16. 3 to Alkmaion (96), which certainly implies that Pythagoras did not hold it. As we shall see (152) it is far from clear that any of the Pythagoreans did. It seems rather to be Plato's discovery.” Cf. ibid. p. 352.
