For my mentioning the things which I am about to tell you this fellow is himself to blame, since he refused to settle our differences among our relatives, but chose to brazen the matter out. For you must know, men of the jury, that this fellow Olympiodorus has never married an Athenian woman in accordance with your laws; he has no children nor has ever had any, but he keeps in his house a mistress whose freedom he had purchased, and it is she who is the ruin of us all and who drives the man on to a higher pitch of madness.
Is it not indeed a proof of his madness that he refuses to do anything whatever that was stipulated in the agreement which was entered into with his full consent and with my own, and which was confirmed by an oath?—especially when I am striving, not in my own interest only, but in the interest of her to whom I am married, his own sister, born of the same father and the same mother, and in the interest of his niece, my daughter. For they are being wronged not less than I, but even more.
