The infatuation of the King for his new favourite decided M. de Sully to hasten by every means in his power the marriage of the sovereign with some European princess worthy to share his throne, and he accordingly instructed the royal agents at Rome to demand forthwith the hand of Marie de Medicis for the French monarch; while Henry, absorbed in his passion, permitted him to act as he saw fit, offering neither assistance nor impediment to a negotiation on which his domestic happiness was in future to depend. Nor was it until the Duke urged upon him the necessity of selecting such of his nobility as it was his pleasure to entrust with the management of the affair in conjunction with the ambassador whom the Grand Duke, her uncle, was about to despatch to Paris, that, by dint of importunity, he was induced to name M. de Sully himself, the Constable, the Chancellor, and the Sieur de Villeroy,[76] whose son, M. d'Alincourt, had previously been sent to Rome to offer the acknowledgments of Henry to his Holiness for the dissolution of his marriage with Queen Marguerite, and to apprise him of that which he was desirous to contract with Marie de Medicis. This duty performed, M. d'Alincourt solicited the permission of the Pope to accompany Sillery to Florence to pay his respects to the Princess and to negotiate the alliance; and having obtained the required sanction, the two nobles set forth upon their embassy, quite unaware that the preliminaries were already nearly concluded.[77] So determined, indeed, had been the minister that no time should be afforded to the King to redeem the pledge which he had given to the favourite that Joannini, the agent of the Grand Duke, had not been many days in Paris before the articles were drawn up and signed on both sides, and Sully was commissioned by the other contracting parties to communicate the termination of their labours to his royal master. The account given by the minister of this interview is highly characteristic. "He had not," says the chronicler, "anticipated such expedition; and thus when I had answered his question of where I had come from by 'We come, Sire, from marrying you,' the Prince remained for a quarter of an hour as though he had been stricken by thunder; then he began to pace the chamber with long strides, biting his nails, scratching his head, and absorbed by reflections which agitated him so violently that he was a considerable time before he was able to speak to me. I entertained no doubt that all my previous representations were now producing their effect; and so it proved, for ultimately recovering himself like a man who has at length taken a decided resolution: 'Well,' said he, striking his hands together, 'well, then, so be it; there is no alternative, since for the good of my kingdom you say that I must marry.'" [78] Such was the ungracious acceptance of the haughty Florentine Princess at the hands of her future bridegroom.
