In Rue du Prévôt we see more old-time vestiges. Rue du Figuier dates from about 1300 when a fig-tree flourished there, cut down three centuries later. Nos. 19-15, now a Jewish hospice, was the abode of the Miron, royal physicians from 1550 to 1680. Every house shows some relic. At No. 5 we come upon an old well and steps in the courtyard. No. 8 was perhaps the home of Rabelais. At No. 1 we find ourselves before the turreted hôtel de Sens, built between 1474 and 1519, on the site of a private mansion given by Charles V to the archbishops of Sens, who at that time had ecclesiastical jurisdiction over Paris. Ecclesiastics of historic fame, and at one time Marguerite de Valois, la Reine Margot, dwelt there during the succeeding 150 years. Then Paris became an archbishopric, and this fine hôtel de Sens was abandoned--let. It has served as a coaching house, a jam manufactory, finally became a glass store and factory, and in part a Jewish synagogue. In Rue du Fauconnier, Nos. 19, 17, 15, are ancient. Rue des Jardins, where stretched the gardens of the old Palais St-Pol, has none but ancient houses. At No. 5 we see a hook which served of yore to hold the chain stretched across the street to close it. Molière lived there in 1645. Rabelais died there. [Illustration: HÔTEL DE SENS] Crossing Rue St-Paul we come to Rue des Lions, recalling the royal menagerie once there. Fine old mansions lie along its whole length. At No. 10 we find a beautiful staircase; another at No. 12, dating from the reign of Louis XIII, and in the courtyard at No. 3 we see an ancient fountain. At No. 14 there was till recent times the fountain “du regard des lions.” No. 17 formed part of l’hôtel Vieuville. Chief among the ancient houses of Rue Charles V is No. 12, l’hôtel d’Antoine d’Aubray, father of the notorious woman-poisoner, la Brinvilliers, with its graceful winding staircase. Here Mme de Brinvilliers tried to bring about the assassination of her lover Briancourt by her other lover Ste-Croix. Nuns, nursing sisters, live there now. Rue Beautreillis was in bygone days the site of a vine-covered trellis in the gardens of the historic palace St-Pol made up of l’hôtel Beautreillis and other fine _hôtels_ confiscated from his nobles by King Charles V, and at No. 1 we see an ancient and truly historic vine climbing a trellis, its origin lost in the mist of centuries. Is it really, as some would have it, a relic of the vines that gave grapes for the table of Charles V? All the houses here are ancient. No. 10 was the mansion of the duc de Valentinois, prince de Monaco in 1640. We see ancient houses along Rue du Petit Musc, a fourteenth-century street. No. 1 is the south side of l’École Massillon (_see_ p. 326). We cross boulevard Henri IV to the Bibliothèque de l’Arsenal, its walls in part, the Arsenal built by Henri IV on the site of a more ancient one, restored in the first half of the eighteenth century, its façade entirely rebuilt under Napoléon III.
