The catacombs are those portions of the ancient stone-quarries under the city which have been used as municipal ossuaries since 1786. As far back as the Roman epoch, the inhabitants of Lutetia were in the habit of drawing their building material from these subterranean quarries, of clay, gypsum, and limestone. The clay, argile plastique, is found in the region of Passy and Grenelle; the zone of gypsum extends from Montmartre to Bercy, and the limestone, rich in fossils, is found under Passy and most of the city on the left bank of the river, from the Jardin des Plantes on the east to the former barrière de Vaugirard on the west. This stone was largely used in the construction of ancient and mediæval edifices,—the Palais des Thermes, the portal of Saint-Julien-le-Pauvre, a portion of Notre-Dame, Saint-Germain-des-Prés, and the old Hôtel-Dieu, were all supplied from the quarries of the Faubourgs Saint-Jacques and Saint-Michel. As the capital increased, these excavations were carried farther; those nearer the centre of the city were gradually filled up after being exhausted of their building material. By 1774, they had become the refuge of numerous thieves and vagabonds, and in consequence of the many accidents caused by the sinking of the earth over them, in the quartiers Saint-Jacques, of the Observatoire, and of Montrouge, in 1774, 1777, and 1778, an official inspection was ordered by the government, and a corps of engineers was directed to carry out all the necessary measures. The credit of the idea of using the quarries of Montsouris and of Montrouge as a receptacle for the bones from the ancient cemetery of the Innocents is ascribed to M. Lenoir, lieutenant général de police, as early as 1780; but it was not till November, 1785, that M. Guillaumot, inspecteur général of the quarries, received definite orders to prepare a suitable place for these relics of mortality.
This officer selected the quarries under the plain of Montsouris in the locality known as the Tombe-Issoire—it was said from a famous brigand of the time of Louis VII, who ravaged this neighborhood, because of their extent and their proximity to the city. It was proposed to deposit in this ossuary not only the bones from the Innocents, but from all the other cemeteries, charniers, and sepulchral chapels of Paris. On the 7th of April, 1786, the quarries were formally blessed by the clergy and consecrated to their new use, and on the same day the transportation of the bones from the Innocents was begun. It was carried on constantly, at the close of each day, in funerary cars covered with a pall and followed by surpliced priests, chanting the service for the dead. This operation, interrupted only during the heat of summer, was completed in less than fifteen months; and the catacombs—so called from this date—have since received a vast number of bones from other cemeteries and churches, and also of the victims of the many street revolutions of the capital. During the Revolution and the Terror, a number of bodies were also thrown in here, and down to 1810 no attempt was made to arrange the bones, which were piled up like rubbish. It is estimated that these subterranean crypts now contain the remains of nearly three millions of persons,—the guide-books say six.
In 1810, a new organization and rearrangement of the catacombs were carried out, the falling roofs were propped up, the galleries cleaned out, ventilated, and dried, and the bones all symmetrically arranged along the walls—the large bones of the arms and legs piled up like cord-wood, presenting their ends, and interrupted by occasional rows, or centre-pieces, or cornices of skulls, and the smaller bones thrown in behind them, between them and the wall, so as to be out of sight. Various attempts at grotesque or fanciful designs, wrought out with craniums and tibias, break the monotony of these grisly corridors. Between 1792 and 1814, the catacombs permitted the suppression of sixteen cemeteries, and they still receive the bones that are turned up in the course of various excavations in the city. Visitors were formerly admitted to explore them every day, but in consequence of the numerous accidents which happened, greater restrictions were imposed, and it is now permitted to make this visit only on the first and third Saturdays of each month, and when furnished with a permit obtained from the Préfet of the Seine. The entrance is on the Place Denfert-Rochereau, and the exit on Rue Dareau; the journey is made under the care of a guide, and the visitor—who is advised to wear sufficiently thick clothing and heavy shoes—is furnished with a candle and a holder for which he pays fifty centimes.
The total number of entrances is sixty-three, many of them outside the city; these galleries are sufficiently well ventilated by numerous openings, and dry. The visitors traverse a certain route, in a general southerly direction, inspecting the various curiosities on the road and the great Ossuaire. In the latter are included several of these,—the Fontaine de la Samaritaine, so called from an inscription which recalls the words of the Saviour to the Samaritan woman; the Tombeau de Gilbert, which is only a column supporting the roof to which was given the form of a sepulchral monument; the Lampe sépulcrale, the Crypte de Saint-Laurent, similar constructions, and the geological collection formed by M. Héricart de Thury, chief engineer of mines and inspector-general of quarries in 1810, which contains specimens of all the earths and minerals encountered in excavating the quarries.
There were formerly to be seen in the Samaritan fountain numerous red fish, which were placed there in 1813 and thrived, but have now disappeared. The quarries are not without animal life,—in the region of the Jardin des Plantes have been found various insects, species of coleoptera, myriapod and thysanoura, and several small crustacea, all more or less blind. One of these latter, a species of small crayfish, inhabits the waters of a little stream which traverses the Ossuaire. The bones of the combatants of 1789 and 1790, and those of the victims of September, 1792, are collected and arranged by themselves in this ossuary. The walls of the galleries are set off with numerous quotations drawn from sacred literature and engraved on pillars in French, Latin, Greek, Italian, and Swedish.
One of the most remarkable of these curiosities, one which was the favorite show-place of the young doctors of the Cochin when they had guests and sufficient candles, is now no longer to be seen. This was a representation of the fort of Port-Mahon, in which he had been imprisoned by the English, cut in the face of the rock in high relief by an old soldier of the king, named Lescure, who had become a stone-cutter after his retirement from the army. This is situated in the quarry of Port-Mahon, under another quarry in the quarter of the Tombe-Issoire, which was discovered by Lescure, who kept his discovery to himself and passed his leisure in executing this record of his past career. When it was completed, he began to talk, and in order to enable his visitors to reach it easily he undertook the construction of a stairway uniting the two quarries; he had scarcely commenced it, when the earth gave way, and the unfortunate artist was crushed in the débris.
Notwithstanding the care taken to shore them up, the roofs of the abandoned quarries still give way occasionally under the superincumbent weight. In May, 1879, a house in the Passage Gourdon, Boulevard Saint-Jacques, sank through the earth; in the following year, a tree in the Luxembourg garden, near the Médicis fountain, did the same thing, and in July of this year, 1880, the lightning fell in this garden, and at almost the same moment two houses in the Boulevard Saint-Michel began to sink, as well as a large section of the sidewalk. These events naturally produced a great excitement in the quarter, and measures were taken to prevent a possible recurrence of such happenings. Proprietors proposing to build in these suspected districts are now required to conform to certain regulations of the inspector-general of quarries, who examines the subsoil under their properties.
