A very different character was that of his younger rival, Francis, duke of Guise, uncle to Mary, queen of Scots, and brother to the regent. Of a bold, aspiring temper, filled with the love of glory, brilliant and popular in his address, he charmed the people by his manners and the splendor of his equipage and dress. He came to court, attended usually by three or four hundred cavaliers, who formed themselves on Guise as their model. His fine person was set off by the showy costume of the time,--a crimson doublet and cloak of spotless ermine, and a cap ornamented with a scarlet plume. In this dress he might often be seen, mounted on his splendid charger and followed by a gay retinue of gentlemen, riding at full gallop through the streets of Paris, and attracting the admiration of the people. [Sidenote: LEAGUE AGAINST SPAIN.] But his character was not altogether made up of such vanities. He was sagacious in counsel, and had proved himself the best captain of France. It was he who commanded at the memorable siege of Metz, and foiled the efforts of the imperial forces under Charles and the duke of Alva. Caraffa found little difficulty in winning him over to his cause, as he opened to the ambitious chief the brilliant perspective of the conquest of Naples. The arguments of the wily Italian were supported by the duchess of Valentinois. It was in vain that the veteran Montmorency reminded the king of the ruinous state of the finances, which had driven him to the shameful expedient of putting up public offices to sale. The other party represented that the condition of Spain, after her long struggle, was little better; that the reins of government had now been transferred from the wise Charles to the hands of his inexperienced son; and that the coöperation of Rome afforded a favorable conjunction of circumstances, not to be neglected. Henry was further allured by Caraffa's assurance that his uncle would grant to the French monarch the investiture of Naples for one of his younger sons, and bestow Milan on another. The offer was too tempting to be resisted. One objection occurred, in certain conscientious scruples as to the violation of the recent treaty of Vaucelles. But for this the pope, who had anticipated the objection, readily promised absolution. As the king also intimated some distrust lest the successor of Paul, whose advanced age made his life precarious, might not be inclined to carry out the treaty, Caraffa was authorized to assure him that this danger should be obviated by the creation of a batch of French cardinals, or of cardinals in the French interest.
