The new quarter soon attracted the attention of rich financiers, civic officers, merchants and lawyers, some of whose hôtels were designed by Levau, and decorated by Lebrun and Leseur. Madame Pompadour's brother lived there; the Duke of Lauzan, husband of the Grande Mademoiselle, lived in his hôtel on the Quai d'Anjou (No. 17); Voltaire lived with Madame du Châtelet in the Hôtel Lambert (No. 1 Quai d'Anjou). To the _précieuses_ of Molière's time the Isle St. Louis (for so it was called) became the Isle de Delos, around whose quays the gallants and ladies of the period were wont to promenade at nightfall. _The Isle_, as it is now familiarly known, is one of the most peaceful quarters of Paris, and has a strangely provincial aspect to the traveller who paces its quiet streets. In 1622 Paris was raised from its subjection to the Metropolitan of Sens, and became for the first time the seat of an archbishopric; the diocese was made to correspond to the old territories of the Parisii. Among the many evils attendant on a monarchy, which Samuel recited to the children of Israel, that of the possibility of a regency might well have found place. Louis XIV. was less than five years of age when his father died, and once again the great nobles turned the difficulties of the situation to their own profit. The queen-regent, Anne of Austria, had retained in office Cardinal Mazarin, Richelieu's faithful disciple, chosen by him to continue the traditions of his policy. The new cardinal-minister, scion of an old Sicilian family, was a typical Italian; he had none of his predecessor's virile energy and directness of purpose, but ruled by his subtle wit and cool, calculating patience. "Time and I," was his device. He was an excellent judge of men, and profoundly distrusted "the unlucky," always satisfying himself that a man was "lucky," before he employed him. Conscious of his foreign origin, Mazarin hesitated to take strong measures, and advised a policy of conciliation with the disaffected nobles. Anne filled their pockets, and for a time the whole language of the court is said to have consisted of the five little words "_La reine est si bonne_." But the ambitious courtiers soon aimed at higher game, and a plot was discovered to assassinate the foreign cardinal. The Duke of Beaufort, chief conspirator, a son of the Duke of Vendôme, and grandson of Henry IV., by Gabrielle d'Estrées, was imprisoned in the keep at Vincennes, and his associates interned at their châteaux.
