La Double Inconstance is a three-act romantic comedy by French playwright Marivaux. Its title is usually translated into English as The Double Inconsistency. La Double Inconstance was first performed 6 April 1723 by the Comédie Italienne. In this play, a young woman is kidnapped from her lover by the prince of the country, who loves her and intends to marry her. Through ruse and disguises, the prince and a trusty female servant manage to break up the relationship, resulting in two marriages.
The play opens with Silva in the palace, pining for her lover, Arlequin, who has also been brought to court. A female servant of the prince, Flaminia, devises a plan to separate the two lovers. She appeals to Silvia's vanity, by suggesting that she needs a more worthy lover. The prince, still disguised as the officer of the palace, continues to be her friend; and Silvia soon realizes that he is a better catch than Arlequin. Meanwhile, Flaminia befriends Arlequin and gradually seduces him away from Silvia. However, both Arlequin and Silvia feel endebted one to the other and are reluctant to separate.
When the prince finally reveals himself, both Arlequin and Silvia are relieved to know that they have an excuse to call of their engagement. The play ends with the union of the two couples: Silvia and the prince, and Flaminia and Arlequin.
