In Rue de Navarre we come to Les Arènes, the disinterred remains of the Roman Arena. They were discovered here just before the war of 1870, then quickly covered up to be in part restored to daylight in 1883. We see before us the grey stones, huge blocks and graduated step-like seats where the population of the city--Lutetians then--passed their hours of recreation watching the conflicts of wild beasts. It is not, perhaps, the original arena built here by the Romans, for that was attacked twice, first by the northern invaders, then by the Christians, many of its stones used to build the city walls. It was, however, soon restored ... evidently. In the course of subsequent invasions, conquests, new settlements, constructions and the lapse of years, the Roman theatre sank beneath the surface to be unearthed in nineteenth-century days. Modern garden paths and a grand but inharmonious entrance in Louis XIV style now surround this supremely interesting vestige of a long-gone age. Children play where savage beasts once fought. Women knit and sew, old men rest, young men and maidens woo, where Roman soldiers and a primitive Gallic population once eagerly gathered to watch fierce combats.[E] Rue Lacépède: here at No. 1 stood till recently the Hôpital de la Pitié, founded by Marie de’ Medici in 1613, now replaced by a modern building in the boulevard de l’Hôpital. Its primary destination was a shelter for beggars--a refuge--in order to free Paris from the swarms who “gained their living” by soliciting alms in the streets. The beggars preferred their liberty. By an edict of some years later, however, beggars were taken there and closely shut up, safely guarded. They were called in consequence “les Enfermés.” The hospital grew in extent and importance and was called “Notre-Dame de la Pitié.” The convent Ste-Pélagie was organized in a part of its buildings, in 1660, to become at the Revolution the notorious prison. No. 7 is a handsome eighteenth-century _hôtel_. Rue Gracieuse has brought down to our time the graceful name of a family who lived there in the thirteenth century and some ancient houses. In Rue du Puits de l’Ermite lived the sculptors Coysevox, Coustou, and the painter Bourdon. The hospice for aged poor in Rue de l’Épée-de-Bois was formerly an _asile_ founded by Sœur Rosalie, known for her self-sacrificing work among the cholera-stricken in 1832, and during the Revolution of 1848. The very name Rue des Patriarches bids us look for vestiges of past ages. The patriarchs, thus memorized, were two fourteenth-century ecclesiastics, one bishop of Paris and Alexandria, the other of Jerusalem, who dwelt in a fine old _hôtel_, the big courtyard of which has become a market-place, while the street named after them and a curious _impasse_ stretch across the site of the razed mansion. The district was a centre of Calvinism during the religious struggles. The bishop’s old house, “hôtel Chanac,” sheltered numerous
