This is a critical edition, or ';edition critique,' of Victor Hugo's play Marion de Lorme. A critical edition is much more than a typical scholarly publication of a literary work that only contains a brief introduction, the text, and endnotes. The in-depth introduction in this critical edition details the history and genesis of the play from its inception through its premiere, as well as a study of the manuscript and of all other original related documents. It also features a history of the premiere, the critical reaction, and an analysis of various nineteenth-century editions of the work. The actual text of the play contains a critical apparatus that indicates all modifications of the text made by the author during its composition. Following the play, there are literary, historical, linguistic, and critical notes, indexes of all words and proper names, and a bibliography of works related to the play in question.(Text in French)
