According to Langlet du Fresnoy, the evidence of these things remained in the year 1742. In the cemetery of the Holy Innocents stood the arch built by Flamel with the hieroglpyhic figures upon it. In two niches, without the arch and on the cemetery side, were statues of St James and St John. Below that of St John was the figure of Flamel himself, reading in a book, with a Gothic N. F. to mark his name. The progression of the colours in the order of the process, originally represented on the wall, was, however, effaced. In the same cemetery was a charnel house, or receptacle for the skulls and bones disinterred in the digging of new graves. Upon one of the pillars of this charnel there was a Gothic N. F., with this inscription:-- _Ce charnier fut fait & donné à l’Eglise, Pour l’amour de Dieu, l’an 1399._ The second of these evidences was upon the Marivaux door of the Church of Saint Jacques-la-Boucherie, where on the left side at entering was the figure of Flamel, kneeling at the feet of St James, with a Gothic N. upon the pedestal. The figure of Perrenelle was represented on the opposite side, kneeling at the feet of St John, the pedestal bearing a Gothic P. The third evidence was in the street of Notre Dame, at the portal of Genevieve of Arden. There Flamel’s statue was to be seen in a niche, kneeling with a desk at his side, looking towards St James. There was a Gothic N. F. below and the inscription, “This portal was built in 1402, by the alms of many.” Flamel is supposed to have concealed in this manner that he was the principal donor, but the figure may have been erected to his memory. The fourth and final evidence was in the street of the cemetery of St Nicholas of the Fields, where there was the wall of an unfinished hospital with figures engraven on the stone and the initials of Flamel. After the death of Perrenelle the bereaved adept is supposed to have prepared for posterity several works on the supreme science which had enriched him:--_Le Livre des Figures Hieroglyphiques_; _Le Sommaire Philosophique_, written in verse after the manner of the _Roman de la Rose_; _Trois Traités de la Transformation Metallique_, also in rhymed verse; _Le Desir Désiré, ou Trésor de Philosophie_; _Le Grand Eclaircissement de la Pierre Philosophale pour la Transmutation de tous Métaux_; _La Musique Chimique_; _Annotationes in D. Zacharmin_, &c.
