M aria Edgeworth wrote whim for whim to be performed at her home by her family in Edgeworthtown, County Longford, Ireland in 1798. The play is a comedy satirizing Illuminatism and features the 1784-85 Affaire du collier de la reine, "Affair of the Queen's Necklace" in which Marie Antoinette was implicated in a scheme to defraud the Crown's jewelers. Set in London, Whim for Whim follows the schemes of Count Babelhausen to break up a love intrigue between Sir Mordent Idem and Mrs. Fangle. In order to secure for himself Fangle's fortune, including a diamond necklace, Babelhausen employs a French maid, Mademoiselle Fanfarlouche, and a servant, Felix. Unbeknownst to Fangle, her fortune has already been lost by a villainous stock broker. Significantly, Fangle, as her name implies, is interested in all the newest fads, as is a Mr. Opal. From the moment the play opens, both are obsessed with Illuminatism. Meanwhile, Opal's uncle, Sir Mordent Idem objects to his ward Caroline's attraction to his nephew. Mordent refuses to consent to their union until Opal adopts a profession. Opal, however, refuses to marry Caroline unless she gives up her large fortune to the cause of Illuminatism. When Babelhausen finds out about Fangle's lost fortune, he next targets Caroline, trying to convince Opal that Fangle, as another Illuminati, is a better match for him. The comedy's denouement occurs during a masquerade allegorizing the play's central conflict, that between tradition and progress, through the costumes of Mordent and Fangle. Mordent goes as Sir Charles Grandison and Fangle as a "Roman Matron, a Savage, and a Sultana." 1 Mordent is scandalized by Fangle's trousers, and she is revolted by his old-fashioned wig. A fortunate costume switch exposes all of Babelhausen's scheming. Mordent proposes to Fangle, Opal agrees to court Caroline, and all pledge to follow
