The support of Louis, conqueror of Milan, had been obtained, and in this Cardinal Giuliano della Rovere had once more been helpful to the Borgias.
His reconciliation with the Pope, long since deserved by the services he had rendered the House of Borgia in forwarding Cesare's aims, as we have seen, was completed now by an alliance which bound the two families together.

His nephew, Francesco della Rovere, had married Alexander's niece, Angela Borgia.
There is a letter from Giuliano to the Pope, dated October 12, 1499, in which he expresses his deep gratitude in the matter of this marriage, which naturally redounded to the advantage of his house, and pledges himself to exert all the influence which he commands with Louis XII for the purpose of furthering the Duke of Valentinois' wishes.

So well does he keep this promise that we see him utterly abandoning his cousins the Riarii, who were likely to be crushed under the hoofs of the now charging bull, and devoting himself strenuously to equip Cesare for that same charge.

So far does he go in this matter that he is one of the sureties--the other being the Cardinal Giovanni Borgia--for the loan of 45,000 ducats raised by Cesare in Milan towards the cost of his campaign.
This is the moment in which to pause and consider this man, who, because he was a bitter enemy of Alexander's, and who, because earlier he had covered the Pope with obloquy and insult and is to do so again later, is hailed as a fine, upright, lofty, independent, noble soul.
Not so fine, upright, or noble but that he can put aside his rancour when he finds that there is more profit in fawning than in snarling; not so independent but that he can become a sycophant who writes panegyrics of Cesare and letters breathing devotion to the Pope, once he has realized that thus his interests will be better served.

This is the man, remember, who dubbed Alexander a Jew and a Moor; this the man who agitated at the Courts of France and Spain for Alexander's deposition from the Pontificate on the score of the simony of his election; this the man whose vituperations of the Holy Father are so often quoted, since--coming from lips so honest--they must, from the very moment that he utters them, be merited.
