She was there also, that other famous female politician, of a grade still higher, as beautiful and as gallant, of a less gracious, perhaps, but yet stronger disposition, more capable still of grand enterprises, and never suffering herself to be stayed by any danger or any scruple--the widow of the Constable de Luynes, Marie de Rohan, Duchess de Chevreuse, who formerly had lent a hand to every plot concocted against Mazarin, and in concert with the Palatine had proposed, as we have seen, the sole measure which could bring together all the Cardinal's enemies, and form a great aristocratical party strong enough to make head against royalty:--the marriage of Conde's son with a daughter of the Duke d'Orleans, and that of her own daughter with the Prince de Conti. This latter match having been broken off in a manner the most outrageous to her feelings, Madame de Chevreuse had separated from Conde with eclat; and, too experienced to ally herself with the sort of _tiers-parti_ which Retz had proposed, but allowing herself to be gently and skilfully guided by the Marquis de Laignes, whom Mazarin with his usual adroitness had known how to win over, she had returned to the side of her early friend, Anne of Austria, and became resigned to the power of a man who at any rate knew his own mind, and whose robust ambition never wavered at the breath of vanity or the gust of momentary passion. The fame and honour that she might expect from the Fronde had been offered to her by Mazarin, and in return Madame de Chevreuse had brought to royalty the declared support of the three illustrious families, the Rohans, De Luynes, and the Lorraines. It was she who, ever puissant over the Duke de Lorraine, had negotiated a secret treaty between him and the Cardinal, and who by turns had made him act in such contrary directions. Restored entirely to the Queen's favour, Madame de Chevreuse was at her side in the Louvre, to welcome warmly the return of the prosperous Cardinal. After Madame de Chevreuse, Mazarin had had no adversaries more dangerous than the Vendomes and Bouillons. And yet on that memorable day of February 3rd, 1653, he could consider the heads of those two powerful families as the firmest supporters of his greatness.
