Roles

Synopsis

Prologue

Mars and Venus and their followers sing the praises of Louis XIV of France, Louis XIV.

Act 1

Princess Aegle is in love with Theseus and prays for his safe return from battle against rebels who are threatening King Aegeus of Athens. Aegeus enters victorious. He tells Aegle he is in love with her, despite being betrothed to the sorceress Medea. Égée says he now intends to marry Medea to his son, whom he has hidden away at Troezen and has not seen for years. The Athenians celebrate their victory with a sacrifice to the goddess Minerva.

Act 2

Medea is in love with Theseus. She agrees to let Aegeus break off their engagement, so he can pursue Aegle. Aegeus is jealous of Theseus's popularity with the people of Athens, who want to make him the king's heir because of his bravery in battle. Medea offers to help Theseus, who reveals to her that he is in love with Aegle, provoking the sorceress to jealousy.

Act 3

Medea threatens Aegle that she will use her magic against her if the princess does not renounce her love for Theseus and marry the king instead. She conjures up a vision of a terrifying desert full of monsters, and also menaces Aegle with demons from hell.

Act 4

Medea orders Aegle to marry Aegeus, otherwise she will put Theseus's life in danger. She conjures a vision of the sleeping Theseus in which she threatens to sacrifice him with a knife. Theseus wakes and is perplexed by Églé's sudden coldness towards him. She explains she is trying to save his life. Theseus reveals that he is Égée's son from Troezen. Medea appears to relent and bless the betrothal of Theseus and Aegle.

Act 5

In reality, Medea is still tortured by jealousy. She persuades Aegeus to kill Theseus, warning him that if he makes Theseus his heir, the king will wrong his missing son. Aegeus hands Theseus a poisoned chalice, but he recognises Theseus's sword and realises the young man must be his son. Just in time, he prevents Theseus from drinking the poison. He agrees to let Theseus marry Aegle. Thwarted, Medea escapes on a flying chariot pulled by dragons, burning down the palace. The Athenians pray to Minerva who raises a magnificent new palace and the opera ends with rejoicing.
