As the play opens, Hippolytus announces to Theramenes, his tutor and friend, his intention of leaving Troezen. Hippolytus is the son of Theseus, king of Troezen and Athens, by his first love, the Amazon Antiope. Theseus is now married to Phaedra, the daughter of his old enemy, Minos of Crete, but he has been gone from Troezen now for more than six months, and his son is determined to go in search of him. Theramenes disapproves; since Theseus' amorous exploits are legendary, he may not want to be found. Hippolytus abruptly cuts off this disrespectful allusion to his father, and says that since his marriage to Phaedra, Theseus has been faithful to her. Duty requires he go look for his father, and he also has reasons of his own for leaving Troezen. Hippolytus' stepmother, Phaedra, has hated him from the first moment she saw him and has spared no effort to make life difficult for him, even driving him into exile in Troezen. But Phaedra has lately been ill to the point of death and Hippolytus should have nothing to fear from her. Hippolytus replies that it is not Phaedra who troubles him but Aricia, princess of a former ruling family of Athens who is now half-ward, half-prisoner of Theseus. Theramenes says he is sorry Hippolytus does not like her, for she is an innocent and charming girl. Hippolytus replies enigmatically, "If I hated her I would not flee her." Theramenes seizes upon the implication and is delighted that Hippolytus, who has never before shown an interest in a woman and who is famous for his chastity, is in love. Hippolytus immediately rejects the idea that he might allow himself to love Aricia. As a child he used to thrill to tales of his father's exploits and his conquest of monsters, but when the gossip turned to his feminine conquestshis kidnapping of Helen, his desertion of Periboea, his elopement with Phaedra's sister, Ariadne, and his later abandonment of her Hippolytus could not help feeling shocked and ashamed. Theseus' light behavior was somewhat excused by his other heroic deeds, but Hippolytus, who has accomplished no such exploits as yet has no such excuse. Moreover, Theseus, fearing to raise up enemies against his regime, has forbidden Aricia to marry and have children. He would certainly not be willing to have her marry his own son. Theramenes is dubious. Love comes to all men, he says; Venus wills it, and when it comes it is nearly irresistible. Why fight such a pleasant emotion, provoked by the gods and approved by them. Firmly, Hippolytus cuts him off. He is determined to leave Troezen. Oenone, nurse to Phaedra, appears.
