They say, moreover, that Tiresias, a Boeotian man, whose fame as touching prophecie is greatly cried up, declared, unto the Greeks that of the errant stars some are masle, some female, and that they do not engender like effects; wherefore they fable that Tiresias himself was bisexous and amphibious, now masle, now female. Here again we have “indepeniiont thought.” A widely variant explanation of the myth had previously been offered by Cephalio (cf. J. Malalas, Chron., p. 40, 1, in the Bonn ition), according to which Tiresias was a student of medicine who concerned himself with the mysteries of parturition.
