We judge it--under the circumstances that Louis XI had surrendered it to the Church--to be a far more flagrant piece of nepotism than was Alexander's now.
Louis XII, nothing behind the Pope in opportunism, saw in the concession asked of him the chance of acquiring Alexander's good-will.

He consented, accompanying his consent by a request for a cardinal's hat for Georges d'Amboise, Bishop of Rouen, who had been his devoted friend in less prosperous times, and the sharer of his misfortunes under the previous reign, and was now his chief counsellor and minister.

In addition he besought--dependent, of course, upon the granting of the solicited divorce--a dispensation to marry Anne of Brittany, the beautiful widow of Charles VIII.

This was Louis's way of raising the price, as it were, of the concession and services asked of him; yet, that there might be no semblance of bargaining, his consent to Cesare's being created Duke of Valentinois was simultaneous with his request for further favours.
With the Royal Patents conferring that duchy upon the Pope's son, Louis de Villeneuve reached Rome on August 7, 1498.

On the same day the young cardinal came before the Sacred College, assembled in Consistory, to crave permission to doff the purple.
After the act of adoration of the Pope's Holiness, he humbly submitted to his brother cardinals that his inclinations had ever been in opposition to his embracing the ecclesiastical dignity, and that, if he had entered upon it at all, this had been solely at the instances of his Holiness, just as he had persevered in it to gratify him; but that, his inclinations and desires for the secular estate persisting, he implored the Holy Father, of his clemency, to permit him to put off his habit and ecclesiastical rank, to restore his hat and benefices to the Church, and to grant him dispensation to return to the world and be free to contract marriage.
