But it would be unjust to attribute these enlightened views to Henry, without noticing that he had a friend as well as minister in Rosny, best known as the Duke de Sully, who probably suggested many of his wisest measures, and at all events superintended their execution, and did his best to prevent or retrieve his sovereign's errors by uncompromising honesty of advice and remonstrance. The allurements of pleasure were powerful over the enthusiastic and impassioned temperament of Henry; it was love that most frequently prevailed over the claims of duty. The beautiful Gabrielle d'Estrees became the absolute mistress of his heart; and he entertained hopes of obtaining permission from Rome to divorce Margaret de Valois, from whom he had long lived in a state of separation. Had he succeeded time enough, he contemplated the dangerous project of marrying the favorite; but her death saved him both from the hazard and disgrace. The sentence of divorce, so long solicited, was at last granted, and the king married Mary de Medici, who bore Louis XIII. to him in 1601. The match, however, contributed little to his domestic happiness. While France was flourishing under a vigilant and paternal administration, while her strength was beginning to keep pace with her internal happiness, new conspiracies were incessantly formed against the king. Henriette d'Entragues, another favorite, not only exasperated the Queen's peevish humor against him, but was ungrateful enough to combine with her father, the Count d'Auvergne, and the Spanish Court, in a plot which was timely discovered. Spite of the many virtues and conciliatory manners of Henry, the fanatics could never pardon his former attachment to the Protestant cause. He was continually surrounded with traitors and assassins; almost every year produced some attempt on his life, and he fell at last by the weapon of a misguided enthusiast.
