27.  But both Greeks and Jews harass us and say that it was impossible for the Christ to be born of a virgin.  As for the Greeks we will stop their mouths from their own fables.  For ye who say that stones being thrown were changed into men See the story of Pyrrha and Deucalion in Pindar, Ol. ix. 60:  ἄτερ δ᾽ εὐνᾶς κτησάσθαν λίθινον γόνον, and in Ovid. Metam i. 260 ff., how say ye that it is impossible for a virgin to bring forth?  Ye who fable that a daughter was born from the brain Athena was said to have sprung armed from the head of Zeus:  Pindar, Ol. vii. 65:  κορυφὰν κατ᾽ ἄκραν ἀνορούσαισ᾽ ἀλάλαξεν ὑπερμάκει βοᾷ.  Cf. Hes. Theog. 924., how say ye that it is impossible for a son to have been born from a virgin’s womb?  Ye who falsely say that Dionysus was born from the thigh of your Zeus Eurip. Bacchae. 295; Ovid. Metam. iv. 11., how set ye at nought our truth?  I know that I am speaking of things unworthy of the present audience:  but in order that thou in due season mayest rebuke the Greeks, we have brought these things forward answering them from their own fables.
