XXXVIII. After this brilliant piece of good fortune, Demetrius received the news that his mother and children had been set at liberty by Ptolemy, who had given them presents and treated them with respect; while he also heard that his daughter, who had been given in marriage to Seleukus, was living with his son Antiochus, with the title of "queen of the native tribes of the interior." It appears that Antiochus fell violently in love with Stratonike, who was quite a young girl, though she had already borne a child to Seleukus. After making many fruitless efforts to resist his passion, he reflected upon the wickedness of indulging a love which he was unable to restrain, and decided that he would put an end to his life. Under pretence of illness he refused to take nourishment, neglected his person, and was quietly sinking. Erasistratus, his physician, had without much difficulty perceived that he was in love, but could not guess with whom. He consequently spent the entire day in the same room with Antiochus, and whenever any young persons came to visit him, narrowly watched his countenance and those parts by which emotion is especially betrayed. He found that his condition was unaltered except when Stratonike came to see him, either alone or with her husband, Seleukus, and that then all the symptoms mentioned by Sappho were visible in him, such as stammering, fiery blushes, failure of eyesight, violent perspiration, disturbed and quickened pulse, and at length, as his passions gained the mastery over him, pallor and bewilderment. Erasistratus, after making these observations, reflected that it was not probable that the king's son would starve himself to death in silence for love of any other woman than his mother-in-law. He judged it to be a perilous enterprise to explain the real state of the case, but, nevertheless, trusting to the love of Seleukus for his son, he one day ventured to tell him that love was really the disorder from which young Antiochus was suffering, and that it was a hopeless and incurable passion. "How incurable?" inquired Seleukus. "Because," answered Erasistratus, "he is in love with my wife." "Well, then," said Seleukus, "will you not give her up, Erasistratus, and marry her to my son, who is your friend, especially as that is the only way out of this trouble for us?" "No," said Erasistratus, "I will not. Why, you yourself, although you are his father, would not do this, if Antiochus were enamoured of Stratonike." To this Seleukus replied, "My friend, I would that by any means, human or divine, his passion could be directed to her; for I would willingly even give up my crown if I could thereby save Antiochus."
