Early in the New Year he returned to Paris, where the charms of Mlle. de Bourbonne were soon forgotten for those of a lady whom he calls la Raverie and who was presumably a star of the _demi-monde_. The courtiers of Henri IV were, however, quite capable of losing their hearts to two or more ladies at the same time, following the example of their royal master, who “fell in love that winter with Madame de Boinville and Mlle. Clin.”[31] In addition to love-making, he danced in several ballets, one of which was appropriately called _le Ballet des Amoureux_.

In February, 1600, Charles Emmanuel of Savoy paid a visit to the Court to negotiate personally with the King about the matter of the marquisate of Saluzzo, which, in 1588, the Duke, taking advantage of the internal troubles of France, had invaded and annexed, and the restoration of which Henri IV was now demanding. Charles Emmanuel offered to enter into an alliance with France against Spain, and assist her to conquer the Milanese, if only Henri IV would forgo his claims on Saluzzo, and lavished costly gifts and large sums of money upon the Ministers and the mistress in order to gain their support. But the King was adamant on the question of Saluzzo, and on February 27 the Duke was obliged to sign a treaty, whereby he engaged within three months either to surrender the marquisate, or, as compensation, the county of Bresse, the valley of Barcellonnette, the valley of the Stura, Pérousse, and Pinerolo.
