Plutarch, Dion

3. Dionysius the Elder, after assuming the reins of government,¹ at once married the daughter of Hermocrates the Syracusan. But she, since the tyranny was not yet securely established, was terribly and outrageously abused in her person by the seditious Syracusans, and in consequence put an end to her own life. [2] Then Dionysius, after resuming the power and making himself strong again, married two wives at once, one from Locri, whose name was Doris, the other a native of the city, Aristomache, daughter of Hipparinus, who was a leading man in Syracuse, and had been a colleague of Dionysius when he was first chosen general with full powers for the war. It is said that he married both wives on one day, and that no man ever knew with which of the two he first consorted, but that ever after he continued to devote himself alike to each; it was their custom to sup with him together, and they shared his bed at night by turns. [3] And yet the people of Syracuse wished that their countrywoman should be honoured above the stranger; but Doris had the good fortune to become a mother first, and by presenting Dionysius with his eldest son she atoned for her foreign birth. Aristomache, on the contrary, was for a long time a barren wife, although Dionysius was desirous to have children by her; at any rate, he accused the mother of his Locrian wife of giving Aristomache drugs to prevent conception, and put her to death.
