CORRIGENDUM

P. 179, lines 26 and 31. It appears that , not , is the correct reading in Timaeus 40 c. The meaning of is of course ‘forward movements’, but the change to this reading does not make it any the more necessary to take in the sense of retrogradations; on the contrary, a ‘forward movement’ and a ‘returning of the circle upon itself’ are quite natural expressions for the different stages of one simple circular motion. Cf. also Republic 617 B, where is used of the ‘counter-revolution’ of the planet Mars; what is meant is a simple circular revolution in a sense contrary to that of the fixed stars, and there is no suggestion of retrogradations.
