In addition to these disreputable adventurers, De Luynes also introduced to the intimacy of his royal patron Deageant,[268] the principal clerk of Barbin, whom he had won over by promises of aggrandizement should he succeed in effecting the disgrace of Concini, which, as a natural consequence, must also involve that of his master; and, finally, a private soldier, and one of the gardeners of the palace.  All these persons were instructed to excite the suspicions of the King against his mother and her ministers, a task in which it was by no means difficult to succeed; particularly when the treacherous Deageant had placed in his hands a number of forged letters, wherein Barbin, at the pretended instigation of Concini, was supposed to entertain a design against his life, in order not only to prolong the authority of the Queen-mother, but also to ensure the crown to her second and favourite son, Gaston d’Orleans.[269]

Skilfully as De Luynes conducted this affair, and despite the natural dissimulation of Louis XIII, the reiterated assertions and cautions of his familiar associates did not fail to produce an involuntary effect upon his manner and deportment which aroused the suspicions of the Italian; who, with an infatuation almost incredible, instead of endeavouring to conciliate the young King, and to render himself less obnoxious to the people, resolved to make all bow before him, and to break the stubborn spirits that he failed to bend.  In this desperate and insane policy he was, moreover, seconded by the counsels of Barbin, whose impetuous temper and anxiety to secure his own safety alike urged him to support any measure which promised to maintain the government in the hands of Marie de Medicis and her favourite, in whose ruin he could not fail to be involved.  So intemperately, indeed, did he pursue his purpose, that even Marie herself became alarmed; her most faithful adherents were absent with the army, while she had daily evidence of the activity of her enemies; and more than once at this period she declared her determination to withdraw from all participation in state affairs, and to resign her delegated authority, in order that her son might rule as he saw fit.  From this purpose she was, however, constantly dissuaded by Barbin.  “Madame,” he said on one occasion when the Queen-mother appeared more than ever resolved to follow out her determination, “if you once abandon the administration of government you will cut the throats of your children.  Should you cease to rule they will be utterly lost.” [270]

No wonder that her tenderness as a mother, joined to her ambition as a Queen, induced Marie de Medicis to yield to the representations of one of her most trusted counsellors, even while the cloud was deepening around her.  As the great nobles murmured at the insolence and tyranny of the audacious Italian, their murmurs were echoed by the curses of the people; and in every murmur and in every curse the name of the Queen-mother was coupled with that of Concini and his
