Lastly, since as cardinals they would by law lose the right of making a will, the pope, in order to inherit from them, had only to poison them: this put him in the position of a butcher who, if he needs money, has only to cut the throat of the fattest sheep in the flock.
The nomination came to pass: the new cardinals were Giovanni Castellaro Valentine, archbishop of Trani; Francesco Remolini, ambassador from the King of Aragon; Francesco Soderini, bishop of Volterra; Melchiore Copis, bishop of Brissina; Nicolas Fiesque, bishop of Frejus; Francesco di Sprate, bishop of Leome; Adriano Castellense, clerk of the chamber, treasurer-general, and secretary of the briefs; Francesco Boris, bishop of Elva, patriarch of Constantinople, and secretary to the pope; and Giacomo Casanova, protonotary and private chamberlain to His Holiness.
The price of their simony paid and their vacated offices sold, the pope made his choice of those he was to poison: the number was fixed at three, one old and two new; the old one was Cardinal Casanova, and the new ones Melchiore Copis and Adriano Castellense, who had taken the name of Adrian of Carneta from that town where he had been born, and where, in the capacity of clerk of the chamber, treasurer-general, and secretary of briefs, he had amassed an immense fortune.
So, when all was settled between Caesar and the pope, they invited their chosen guests to supper in a vineyard situated near the Vatican, belonging to the Cardinal of Corneto. In the morning of this day, the 2nd of August, they sent their servants and the steward to make all preparations, and Caesar himself gave the pope's butler two bottles of wine prepared with the white powder resembling sugar whose mortal properties he had so often proved, and gave orders that he was to serve this wine only when he was told, and only to persons specially indicated; the butler accordingly put the wine an a sideboard apart, bidding the waiters on no account to touch it, as it was reserved for the pope's drinking.
[The poison of the Borgias, say contemporary writers, was of two kinds, powder and liquid. The poison in the form of powder was a sort of white flour, almost impalpable, with the taste of sugar, and called Contarella. Its composition is unknown.
The liquid poison was prepared, we are told in so strange a fashion that we cannot pass it by in silence. We repeat here what we read, and vouch for nothing ourselves, lest science should give us the lie.
A strong dose of arsenic was administered to a boar; as soon as the poison began to take effect, he was hung up by his heels; convulsions supervened, and a froth deadly and abundant ran out from his jaws; it was this froth, collected into a silver vessel and transferred into a bottle hermetically sealed, that made the liquid poison.]
Towards evening Alexander VI walked from the Vatican leaning on Caesar's arm, and turned his steps towards the vineyard, accompanied by Cardinal Caraffa; but as the heat was great and the climb rather steep, the pope, when he reached the top, stopped to take breath; then putting his hand on his breast, he found that he had left in his bedroom a chain that he always wore round his neck, which suspended a gold medallion that enclosed the sacred host. He owed this habit to a prophecy that an astrologer had made, that so long as he carried about a consecrated wafer, neither steel nor poison could take hold upon him. Now, finding himself without his talisman, he ordered Monsignors Caraffa to hurry back at once to the Vatican, and told him in which part of his room he had left it, so that he might get it and bring it him without delay. Then, as the walk had made him thirsty, he turned to a valet, giving signs with his hand as he did so that his messenger should make haste, and asked for something to drink. Caesar, who was also thirsty, ordered the man to bring two glasses. By a curious coincidence, the butler had just gone back to the Vatican to fetch some magnificent peaches that had been sent that very day to the pope, but which had been forgotten when he came here; so the valet went to the under butler, saying that His Holiness and Monsignors the Duke of Romagna were thirsty and asking for a drink. The under butler, seeing two bottles of wine set apart, and having heard that this wine was reserved for the pope, took one, and telling the valet to bring two glasses on a tray, poured out this wine, which both drank, little thinking that it was what they had themselves prepared to poison their guests.
Meanwhile Caraffa hurried to the Vatican, and, as he knew the palace well, went up to the pope's bedroom, a light in his hand and attended by no servant. As he turned round a corridor a puff of wind blew out his lamp; still, as he knew the way, he went on, thinking there was no need of seeing to find the object he was in search of; but as he entered the room he recoiled a step, with a cry of terror: he beheld a ghastly apparition; it seemed that there before his eyes, in the middle of the room, between the door and the cabinet which held the medallion, Alexander VI, motionless and livid, was lying on a bier at whose four corners there burned four torches. The cardinal stood still for a moment, his eyes fixed, and his hair standing on end, without strength to move either backward or forward; then thinking it was all a trick of fancy or an apparition of the devil's making, he made the sign of the cross, invoking God's holy name; all instantly vanished, torches, bier, and corpse, and the seeming mortuary, chamber was once more in darkness.
Then Cardinal Caraffa, who has himself recorded this strange event, and who was afterwards Pope Paul IV, entered baldly, and though an icy sweat ran dawn his brow, he went straight to the cabinet, and in the drawer indicated found the gold chain and the medallion, took them, and hastily went out to give them to the pope. He found supper served, the guests arrived, and His Holiness ready to take his place at table; as soon as the cardinal was in sight, His Holiness, who was very pale, made one step towards him; Caraffa doubled his pace, and handed the medallion to him; but as the pope stretched forth his arm to take it, he fell back with a cry, instantly followed by violent convulsions: an instant later, as he advanced to render his father assistance, Caesar was similarly seized; the effect of the poison had been more rapid than usual, for Caesar had doubled the dose, and there is little doubt that their heated condition increased its activity.
