She Ventures and He Wins (1696) is a comedy in five acts by His Majesty's servants and written by a Young Woman under the pseudonym of "Ariadne".
 The author, who is referred to by most documents and historians by her pseudonym, caused an uproar between the theaters of the area and, because of her writing, this play helped to start the theatrical tradition of cross-dressing.
 Ariadne is noted as writing with humor and wit that matches that of her contemporaries.
 The original manuscript mentioned it was an adaptation of a "small novel", which has since been discovered to be "The Fair Extravagant" by Alexander Oldys, an unknown story that had been almost unheard of since its publication.
 Much of the plot remains the same with detail, some plot points, and characters changed.
 The main character in the Oldys text's name is Ariadne.
