These events caused the gravest scandal throughout Christendom. Cardinal Riario was the Dean of the Sacred College, and many preferred to think that the plot was an invention for the purpose of securing funds rather than that the cardinals had sunk so low. The dilemma was painful, but we can have little doubt that Leo, at least, was convinced of the reality of the plot. Instead of proceeding with greater caution, however, he went on to give a fresh ground of criticism. In a Consistory which he held on June 26th, he told the cardinals that he was going to add no less than twenty-seven members to their college. Their stormy protests increased his determination, and on July 1st he promoted thirty-one cardinals. The rumour at once spread through Christendom, and is in substance undoubted, that most of the new cardinals paid large sums of money for the dignity; Sanuto makes individual payments rise as high as 30,000 ducats. Some of them were men of low character, and others were either related to, or had lent money to, the Pope. We may, however, conclude the political consideration before we discuss these domestic matters. Maximilian induced the Diet of Augsburg to elect his grandson Charles as his successor to the imperial title, and, as a Bull of Julius II. enacted that the investiture of the kingdom of Naples reverted to the Papacy if its holder became King of Rome, the Pope was pressed to give a dispensation from this Bull. Leo pleaded that his "honour" was at stake; but he secretly negotiated with Francis (who bitterly opposed the dispensation) and with Charles, and bargained shamelessly for his refusal or consent. In the end Francis (out of funds raised in the name of a crusade) gave Lorenzo de' Medici 100,000 ducats "for services rendered," and promised a further sum of 100,000 to the Pope. It is an equally undisputed fact that on January 20, 1519, Leo, Lorenzo, and Francis entered into an alliance; the Pope and his nephew were to promote the interests of Francis, and the French King was to protect the Papal States and the estates of the Medici family, and to admit the claims of the Church at Milan. It is, perhaps, the choicest example of Leo's diplomacy--"unparalleled double-dealing," Dr. Pastor calls it--that he secretly drew up a similar treaty with Spain and signed it a fortnight after he had signed the preceding (February 6th).
