On The Estate of Ciron

How is one to prove clearly that all these events occurred in face of the imputations which our opponents are now uttering? I sought and discovered a way. Whether my mother was or was not the daughter of Ciron, whether she lived in his house or not, whether he did or did not on two occasions give a feast in honor of her marriage, and what dowry each of her husbands received with her—all these things must necessarily be known to the male and female slaves who belonged to Ciron.
