Caesar, on his entrance, found the captive seated, leaning his elbows on a table, and he took a seat opposite him and explained the pope’s position: it was an embarrassing one. At the very time of contracting so important an alliance with the house of Aragon as that of Lucrezia and Alfonso, His Holiness could not avow to Ferdinand and Isabella that, for the sake of a few miserable ducats, he had signed a dispensation which would unite in the husband and wife together all the legitimate claims to a throne to which Ferdinand and Isabella had no right at all but that of conquest. This avowal would necessarily put an end to all negotiations, and the pontifical house would fall by the overthrow of that very pedestal which was to have heightened its grandeur. Accordingly the archbishop would understand what the pope expected of his devotion and friendship: it was a simple and straight avowal that he had supposed he might take it upon himself to accord the dispensation. Then, as the sentence to be passed on such an error would be the business of Alexander, the accused could easily imagine beforehand how truly paternal such a sentence would be. Besides, the reward was in the same hands, and if the sentence was that of a father, the recompense would be that of a king. In fact, this recompense would be no less than the honour of assisting as envoy, with the title of cardinal, at the marriage of Lucrezia and Alfonso—a favour which would be very appropriate, since it would be thanks to his devotion that the marriage could take place. The Archbishop of Cosenza knew the men he was dealing with; he knew that to save their own ends they would hesitate at nothing; he knew they had a poison like sugar to the taste and to the smell, impossible to discover in food—a poison that would kill slowly or quickly as the poisoner willed and would leave no trace behind; he knew the secret of the poisoned key that lay always on the pope’s mantelpiece, so that when His Holiness wished to destroy some one of his intimates, he bade him open a certain cupboard: on the handle of the key there was a little spike, and as the lock of the cupboard turned stiffly the hand would naturally press, the lock would yield, and nothing would have come of it but a trifling scratch: the scratch was mortal. He knew, too, that Caesar wore a ring made like two lions’ heads, and that he would turn the stone on the inside when he was shaking hands with a friend. Then the lions’ teeth became the teeth of a viper, and the friend died cursing Borgia. So he yielded, partly through fear, partly blinded by the thought of the reward; and Caesar returned to the Vatican armed with a precious paper, in which the Archbishop of Cosenza admitted that he was the only person responsible for the dispensation granted to the royal nun.
