Although the Galerie Louis XIV, on the upper floor of the long gallery, is not particularly beautiful or well decorated, it is interesting because here were first presented some of the plays of Jean Jacques Rousseau, _L'Engagement Temeraire_ and _Le Devin du Village_. Such later associations as this under the _regime_ of the _Fermier General_ and Madame Dupin are those of an altogether peaceful and homelike abode. In his _Confessions_ Rousseau says: "We amused ourselves greatly in this fine spot. We made a great deal of music and acted comedies. I wrote a comedy, in fifteen days, entitled _L'Engagement Temeraire_, which will be found amongst my papers; it has not other merit than that of being lively. I composed several other little things: amongst others a poem entitled, _L'Allee de Sylvie_, from the name of an alley in the park upon the banks of the Cher; and this without discontinuing my chemical studies or interrupting what I had to do for Madame D----n." Rousseau was at this time acting as secretary to Madame Dupin and her son-in-law, Monsieur Francueil. Elsewhere he complains that these two _dilettanti_ were so occupied with their own productions that they were disposed to belittle the genius of their brilliant secretary, which, after all, was not unnatural, as the "New Eloisa" and his other famous works had not then been given to the world. Monsieur Crapaud explained to us that Madame Dupin was not only a beauty and a _precieuse_, but an excellent business woman, so clever, indeed, that she managed to prove, by hook or by crook, that Chenonceaux had never been absolutely crown property and so did not fall under the _coup de decret_. She retained this beautiful chateau during the Revolution, and lived here in heroic possession, during all the upheavals and changes of that tumultuous period.
