to make them hesitate to touch it. Besides, the things of the sepulchre must be left in the spot which they select. In short, the relic was a strange one. A Marquise had slept in it; Marat had rotted in it; it had traversed the Pantheon to end with the rats of the sewer. This chamber rag, of which Watteau would formerly have joyfully sketched every fold, had ended in becoming worthy of the fixed gaze of Dante.
The whole visit to the subterranean stream of filth of Paris lasted seven years, from 1805 to 1812. As he proceeded, Bruneseau drew, directed, and completed considerable works; in 1808 he lowered the arch of the Ponceau, and, everywhere creating new lines, he pushed the sewer, in 1809, under the Rue Saint-Denis as far as the fountain of the Innocents; in 1810, under the Rue Froidmanteau and under the Salpêtrière; in 1811 under the Rue Neuve-des-Petits-Pères, under the Rue du Mail, under the Rue de l’Écharpe, under the Place Royale; in 1812, under the Rue de la Paix, and under the Chaussée d’Antin. At the same time, he had the whole network disinfected and rendered healthful. In the second year of his work, Bruneseau engaged the assistance of his son-in-law Nargaud.
