Cinq-Mars (opera)

It was revived by Leipzig Opera in May 2017, conducted by David Reiland, in a production by Anthony Pilavachi, with Mathias Vidal in the title role.

Whereas de Vigny's character yearned to become her social equal, the opera's hero enters politics only on learning of a planned marriage between Marie and the king of Poland.

After the conspiracy is discovered, she is given a chance to save him by agreeing to the match, but her sacrifice is in vain: before their escape plans can be put into effect, the hour of execution is suddenly moved forward.

Marion announces that she will organize a ball the next day, which will give them the opportunity to cast the basis of an intrigue to eliminate the Cardinal.

He declares that the King is no longer in total control of the country, and that the eviction of the Cardinal is a just cause; civil war is imminent, and he assures his co-conspirators that he arranged a treaty with Spain, which implies that their armies will intervene on their side.

De Thou suddenly interrupts him, and warns him against opening France up to a foreign power, but the marquis remains resolute.

Marie appears, contrary to all expectations, and agrees with Cinq-Mars to immediately exchange wedding vows ("Madame, c'est le lieu du rendez-vous").

Further, he tells her, the Polish ambassador will return soon from a hunt with the King, and Father Joseph advises Marie to answer him favorably; in exchange, Cinq-Mars will be spared.

When the chancellor and Father Joseph come to announce that the marquis will die before the dawn, it becomes clear that this plan will not happen ("Messieurs, appelez à vous, votre courage").
