From that time the Marquis d’Ancre became pre-eminent at Court; and not only the ministers, but even the Princes of the Blood themselves, looked with distrust upon his power over the Queen.  Between the Italian favourite and the Duc d’Epernon especially, a feeling of hatred had grown up, which, although as yet veiled by the policy for which each was so distinguished, only awaited a fitting opportunity to reveal itself on both sides; and the struggle for power was not the less resolute because it was carried on amid smiles and courtesies.  Meanwhile, also, the Princes de Guise and de Lorraine evinced symptoms of disunion, which threatened the most serious consequences; and amid all this chaos of conflicting interests and passions the royal authority was treated with contempt, and Marie began to tremble for the stability of her regency.[103]

Early in the month Concini entered upon his duties as First Lord of the Bedchamber, and had a serious misunderstanding with the Duc de Bellegarde, who refused to allow him to take possession of the apartments in the Louvre set aside for the person holding that rank during the year in which he was on duty, on the pretext that the Marquise his wife being already lodged in the palace, he had no right to claim any further accommodation.  Concini insisted on the privilege of his office, upon which M. le Grand, to whom he had become hateful from his arrogance and pretension, retorted in a manner which excited his temper; and high and bitter words were exchanged that threatened the most serious results, when the Italian, suddenly recollecting that he was exasperating by his violence an enemy too powerful for him to contend against without support, declared that he would pursue the quarrel no further in person, but would place his honour in the hands of the Comte de Soissons, and abide by his decision.  Against such a determination M. de Bellegarde had, of course, nothing to urge; and the Italian forthwith requested the Marquis de Coeuvres, in whom M. de Soissons had great confidence, to represent the affair to that Prince, and to assure him that he would be entirely governed by his advice.

The Duc d’Epernon, delighted to find that Concini had made a new enemy, strenuously exerted himself to induce M. le Grand to maintain his ground, a counsel which the latter was well disposed to follow; but the Comte de Soissons, who was anxious to secure the influence of the Italian Marquis that he might the more readily effect the marriage of his son, eagerly embraced so favourable an opportunity of purchasing his good offices; and consequently represented in stringent terms to his opponent the utter impracticability of refusing to concede to M. d’Ancre the same consideration and indulgence which had been enjoyed by his predecessors in office, together with the danger that he personally incurred by so gratuitously offending an individual protected by the Regent.  Whatever additional arguments he may have advanced, it is impossible to decide; suffice it that the Duke yielded, the quarrel was terminated, and Concini established in the coveted apartments; at which his gratification was so unmeasured that he pledged himself to M. de Soissons to induce the ministers to consent to the union of the Comte d’Enghien with the heiress of Montpensier, as well as to exert himself in preventing the marriage of the Duc de Guise and the Duchess her mother.[104]
