Dionysius is a sympathetic and noble character; indeed his sins are all for love. He is in deep mourning for his dead wife when Callirhoe is purchased as a slave by his manager. Although he believes that no person who is not free-born can be truly beautiful, he is overwhelmed with love at the first sight of Callirhoe. With tactful sympathy he draws out her story and believes it. He never forces his passion upon her, but woos her delicately through his maid-servant, Plangon, and is overjoyed when Callirhoe finally consents to legal marriage for the purpose of raising a family. Even then in spite of his desire he delays the marriage that he may do Callirhoe the honor of a great wedding in the city. His happiness is complete to his mind when after seven months a son is born. So it is because of his sincere love that when he hears that a Syracusan warship has arrived to demand Callirhoe back, he commends his slave Phocas who out of loyalty to his master had persuaded barbarians to destroy the ship and its crew. Dionysius’ only anxiety is that since some of the men escaped, Chaereas may still be alive. This last fact he conceals from Callirhoe and to comfort her for Chaereas’ supposed death persuades her to erect a cenotaph to her first husband’s memory. Later when he receives the intercepted letter of Chaereas to Callirhoe, he faints with grief and fear, but coming to he believes the letter forged as part of a plot of Mithridates to win the favor of his bride, so he accuses Mithridates to the Great King. Summoned to Babylon to the trial he is in constant terror, for “he looked on all men as his rivals” knowing the devastating effects of Callirhoe’s beauty. When Chaereas is produced alive in the trial, he argues valiantly for the retention of his wife with some telling thrusts at Chaereas, but finally when he has lost his love, he bears his grief like a man, having remarkable self-control, treasuring Callirhoe’s affectionate letter as true solace, and devoting himself to her son. Dionysius, as Callirhoe reminds him once, is a Greek with a Greek education.
