“In real truth,” cried Madonna Isabella to her feeble spouse, “thou art Duke of Milan, and I thy Duchess. But thou art content to abide in Pavia while that Black, Don Ludovico, ruleth in thy duchy, and seateth Madonna Beatrice near him in my place on thy throne. I will have that girl to know that she is no duchess, and that I, I Isabella, am Duchess of Milan.” And the lady wrote to her father, Don Alonso de Aragona Duke of Calabria, who was heir to the crown of the Regno, inciting him to resent the insult put upon her, his daughter, to end the usurpation of Don Ludovico Maria, and to restore Duke Giangaleazzo to his duchy. Duke Don Alonso was not unwilling. War was imminent between Naples and Milan. Then the Pope died; the Lord Alexander P.P. VI succeeded Him; and, it being an age when the Pope frankly was admitted to be Ruler of the World, Father of princes and of kings, etc., all Italy and Christendom waited to know the new Pope’s pleasure. This was the first of a series of extremely delicate positions in which the Lord Alexander P.P. VI found Himself involved. On the one hand, the Papacy was at peace with Naples. On the other, the Pope’s Holiness found His brilliant young Vicechancellor-Cardinal Ascanio Maria Sforza-Visconti to be exceedingly valuable; and he was own brother to that Don Ludovico Maria (detto Il Moro) against whom Naples was invoked. Momentous consequences waited on His action. * * * * * On the eleventh of December 1492, there arrived in Rome Don Federigo de Aragona, Prince of Altamura, second son of King Don Ferrando I, ostensibly to offer to the Pope’s Holiness the obedience of Naples, with congratulations on His coronation. The royal envoy sumptuously was entertained by Cardinal Giuliano della Rovere, whose chief occupations at this period appear to have been the feeling of the pulses of the Powers, and the search for a potentate willing to be used against the Borgia. Manifestations of goodwill between Papacy and Regno pleased the Romans. The frontier of Naples was but a day’s ride from Rome; and the Romans liked to feel that beyond that frontier flourished a friend, not lurked a foe. In private audience, however, Don Federigo said that the assistance of the Pope’s Holiness was required in a family affair; and he made it clear that the attitude of Regno to Papacy would be determined by the extent to which the Lord Alexander P.P. VI would go on behalf of Naples.
