In 1364, he succeeded to the throne, under the title of Charles V, and by his wise administration, his prudent conduct of the war, and the judicious management of the finances, secured for himself the surname of "the Sage." He rendered the parliament permanent, instead of occasional, and he gave it for its sittings in the Cité the ancient palace of Saint-Louis, which became the Palais de Justice. A royal ordinance, which remained in force till the Revolution, fixed the majority of the kings of France at thirteen years of age, and provided that the regent should _not_ be the guardian of the young prince; another, dated in 1370, authorized the bourgeois of Paris to wear the spurs of gold and other ornaments of the order of knighthood, and a third, of 1377, awarded titles of nobility to the _prévôts_ and _échevins_, or aldermen, of the city. In 1369, the authority of the _prévôt_ of Paris was officially confirmed in regard to all offences and misdemeanors committed within the city by any person whatsoever. Among the many important buildings which this king erected or commenced was the Bastile, founded in 1370, to replace the old Porte Saint-Antoine, and consisting at first of two towers, united by a fortified gate; the Louvre, repaired and enlarged; the fortifications of the city; the Hôtel Saint-Pol, the gardens of which descended to the Seine; the chapelle of Vincennes, and several châteaux in the environs of the city. Nevertheless, and in spite of the encouragement given by Charles V to letters, the capital and the nation shared in the general decadence of the century, in morals, in intellect, and even in physical force. It has been estimated that while the average duration of human life was thirty years during the Roman Empire, it had now diminished to seventeen. The readers of Voltaire will remember that in _The Man with the Forty Écus_ his "geometer" gives it as twenty-two or twenty-three years for Paris, and contrives to reduce this brief span to practically two or three years of active, enjoyable life,--ten years off the twenty-three for the period of youthful immaturity, ten more for the decline of old age, sleep, sickness, work, worry, etc.! Duruy cites two instances of feminine peers of France. In 1378, the Duchesse d'Orléans writes to excuse herself from coming to take her seat as a peer in the Parliament of Paris; the Duchesse d'Artois, Mahaut, had been present at the coronation of Philippe V, and had supported, with the other peers, the crown on the head of the king.
