Apparently Orphism was already established at Croton in southern Italy when Pythagoras arrived there about 530 B.C.; but the matter is very uncertain. It is clear that Orphism and Pythagoreanism soon coalesced, even if they were originally distinct. 10. _Rep._, vi, 508 f. It should be said that the identity of Plato’s supreme idea with God is denied by some Platonists; but cf. _Phil._ 22C; _Tim._ 28A-29E, 57A, 92C. 11. The doctrine of ideas is developed in the _Phaedo_, _Phaedrus_, _Meno_, _Symposium_, and especially in the _Republic_. In the _Sophist_ and the _Parmenides_, Plato criticizes his own views acutely. 12. _Metaphys._, i, 9; vi, 8; xii, 10; xiii, 3. 13. _Phaedrus_, 245 (cf. _Laws_, x, 894B ff., xii, 966E); _Phaedo_, 72 ff., 86, 105; _Meno_, 81 ff. 14. _Diss._, i, 14, 6; ii, 8, 11. 15.
