Now Mithridates too had fallen in love with Callirhoe on seeing her at Miletus. On returning to Caria he discovers the identity of his slave Chaereas just in time to save him from crucifixion because of an uprising of his fellow-slaves, and tells him that his wife is now married to Dionysius. Chaereas writes a letter to Callirhoe full of penitence and of love and Mithridates forwards it by Hyginus, his faithful slave, adding another letter of his own promising Chaereas and Callirhoe his aid. Unfortunately these letters fall into the hands of Dionysius himself and that noble prince, in his mad passion for his wife, conceals from her the news that Chaereas is alive and makes a plot for the protection of his own interests. He appeals to Pharnaces, governor of Lydia and Ionia, who is also in love with Callirhoe, to help a scheme he has made. Pharnaces thus prompted writes a letter to Artaxerxes, King of the Persians, accusing Mithridates of trying to corrupt Dionysius’ wife. The great King then summons Mithridates to a trial for plotting adultery and sends also for Dionysius and Callirhoe. The court scene is full of magnificence and surprises. Mithridates has no fear because in answer to the denunciations of Dionysius he is able to produce as a witness Chaereas who swears to his innocence and friendship. Mithridates is acquitted and departs. Then the King dismisses the court for five days before adjudging whose wife Callirhoe is to be since now she has two living husbands. Meanwhile he intrusts the lady for safe keeping to his wife, Statira. Dionysius is torn between the promptings of passion and reason. Chaereas is in despair at the possibility of losing Callirhoe again. And Artaxerxes, the King, like all the other great gentlemen in the story, falls madly in love with Callirhoe for her beauty. The King’s passion makes him postpone the court trial a month on the pretext of a dream which demanded sacrifice to the gods. His eunuch tries to persuade the heroine to do herself the honor of submitting to the King’s embraces, but only horrifies and offends her purity. Now Fortune again takes a hand in separating once more Chaereas and Callirhoe, for a revolt of the Egyptians is announced, the King must be off to war, and as usual the queen and her suite go with him. Callirhoe accompanies the queen by royal orders.
