Although discredit was thrown upon these documents by the Roman court, and the whole affair was alleged to be a device of Cardinals della Rovere and Gurk, to screen the Prefect at the Pontiff's expense,[220] it appears clear that a bribe was offered by Bajazet for the destruction of his brother, who did not long survive this incident. Alexander accepted 20,000 ducats from Charles VIII. to put Gem into his hands during six months, as a tool for his ambitious design upon the East; and in the treaty between his Holiness and the French monarch, dated 15th January, 1495, there is a special article that the former should consign "the Turk" to his Majesty as a hostage, to be kept in the castle of Terracina, or elsewhere, in the ecclesiastical territories, from whence Charles came under a promise not to remove him "unless in case of need, in order to prevent an invasion of the other Turks, or to make war upon them." He also bound himself to defend the Pope from any descent of the Infidel upon the Adriatic coast, and, on quitting Italy, to restore Gem to his custody, his Holiness meanwhile continuing to draw the Sultan's pension, and for due observance of these conditions, Charles bound himself in a penalty of 800,000 ducats. By another article he undertook to arbitrate in the complaint brought against the Prefect, in the affair of Bucciardo and the captured subsidy. It is further stipulated that the Cardinal della Rovere should be restored to favour, and replaced as legate at Avignon; and that, on termination of the Neapolitan enterprise, Ostia should be again surrendered into his hands.[221] [Footnote 220: _Lettere de' Principi_, II., 4.] [Footnote 221: _Molini Documenti di Storia Italiana_, I., 23.]
