The play is set at the royal court in Troezen, on the Peloponnesus coast in Southern Greece.[2]
Act 1. Following Theseus's six month absence, his son Hippolytus tells his tutor Theramenes of his intention to leave Troezen in search of his father. When pressed by Theramenes, he reveals that the real motive is his forbidden love for Aricia, sole survivor of the royal house supplanted by Theseus and under a vow of chastity against her will.

To avert Phèdre's deathwish and her possible betrayal by Hippolytus, Oenone urges that a story should be concocted around his
