Around this execution have clustered the usual growth of legends and invention that supplement the great, trenchant facts of history with an embroidery to which history does not always condescend. The fine words which the king's confessor, the Abbé Edgeworth, are supposed to have addressed to him on the scaffold: "Son of Saint-Louis, ascend to heaven!" were invented on the day of the execution by a journalist named Charles His. The picturesque story of a secret midnight mass, celebrated every year on the anniversary of the execution, at the instigation and at the expense of the executioner Sanson, is equally devoid of foundation. It first appeared in the preface of a work published in 1830, under the title of _Mémoires pour servir à l'histoire de la Revolution française_, by SANSON, _exécuteur des arrêts criminels_. The preface was written by Balzac, the work itself by a certain Lhéritier, and Balzac reproduced the story with appropriate embellishments in his _Une Messe en 1793_, and later in the _Episode sous la Terreur_. One of the nuns who, in the first account, appeared as Mlle. de Charost here becomes the Mlle. de Langeais who figures so picturesquely and improbably in several of his romances. In the _Biographie universelle_, Michaud relates that Sanson, in his will, left directions to have a commemorative mass celebrated every year on the 21st of January; that he was so affected by the execution of the king that he fell ill immediately afterward, and died within six months, and that the provisions of the will were faithfully executed by his son and successor until his own death, in 1840. It appears, however, that the elder Sanson continued "to function" all through the Terror, did not die till 1806, and that any attempt to carry out the pretended provisions of his will would have been very dangerous to his son, and to any notary who might have drawn it up. Through the Terror, and even under the Directory, there are numerous records of sentences of deportation against priests who had celebrated requiem masses for the repose of the soul of Louis XVI. The famous _Messe de Sanson_ appears to have been invented out of the whole cloth by Balzac.
