During the pontificate of Innocent VIII., Francesco Negro, a Milanese by birth, was governor of Rome and him Peter Martyr served as secretary; a service which, for some reason, necessitated several months' residence in Perugia. His relations with Ascanio Sforza, created cardinal in 1484, continued to be close, and at one period he may have held some position in the cardinal's household or in that of Cardinal Giovanni Arcimboldo, Archbishop of Milan, though it is nowhere made clear precisely what, while some authorities incline to number him merely among the assiduous courtiers of these dignitaries from his native Lombardy.
The fame of his scholarship had meanwhile raised him from the position of disciple to a place amongst the masters of learning, and in his turn he saw gathering about him a group of admirers and adulators. Besides Pomponius Lætus, his intimates of this period were Theodore of Pavia and Peter Marsus, the less celebrated of the Venetian brothers. He stood in the relation of preceptor or mentor to Alonso Carillo, Bishop of Pamplona, and to Jorge da Costa, Archbishop of Braga, two personages of rank, who did but follow the prevailing fashion that decreed the presence of a humanist scholar to be an indispensable appendage in the households of the great. He read and commented the classics to his exalted patrons, was the arbiter of taste, their friend, the companion of their cultured leisure, and their confidant. Replying to the praises of his disciples, couched in extravagant language, he administered a mild rebuke, recalling them to moderation in the expression of their sentiments: "These are not the lessons you received from me when I explained to you the satire of the divine Juvenal; on the contrary, you have learned that nothing more shames a free man than adulation."[7]
[Note 7: Epist. x. _Non hæc a me profecto, quam ambobus Juvenalis aliguando divinam illam, quæ proxima est a secunda, satiram aperirem, sed adulatione nihil esse ingenuo foedius dedicistis_.]
The year 1486 was signalised in Rome by the arrival of an embassy from Ferdinand and Isabella to make the usual oath of obedience on behalf of the Catholic sovereigns of Castille and Leon to their spiritual over-lord, the Pope. Iñigo Lopez de Mendoza, Count of Tendilla, a son of the noble house of Mendoza, whose cardinal was termed throughout Europe _tertius rex_, was the ambassador charged with this mission.[8] Tendilla shone in a family in which intellectual brilliancy was a heritage, the accomplishments of its members adding distinction to a house of origin and descent exceptionally illustrious. Whether in the house of his compatriot, the Bishop of Pamplona, or elsewhere, the ambassador made the acquaintance of Peter Martyr and evidently fell under the charm of his noble character and uncommon talents. The duties of his embassy, and possibly his own good pleasure, detained Tendilla in Rome from September 13, 1486, until August 29th of the following year, and, as his stay drew to its close, he pressingly invited the Italian scholar to return with him to Spain, an invitation which neither the remonstrances nor supplications of his friends in Rome availed to persuade him to refuse. No one could more advantageously introduce a foreigner at the Court of Spain than Tendilla. What prospects he held out or what arguments he used to induce Martyr to quit Rome and Italy, we do not know; apparently little persuasion was required. A true child of his times, Peter Martyr was prepared to accept his intellectual heritage wherever he found it. From the obscure parental village of Arona, his steps first led him to the ducal court of Milan, which served as a stepping-stone from which he advanced into the wider world of Rome. The papal capital knew him first as a disciple, then as a master, but the doubt whether he was satisfied to wait upon laggard pontifical favours is certainly permissible. He had made warm friendships, had enjoyed the intimacy of the great, and the congenial companionship of kindred spirits, but his talents had secured no permanent or lucrative recognition from the Sovereign Pontiff. The announcement of his resolution to accompany the ambassador to Spain caused consternation amongst his friends who opposed, by every argument they could muster, a decision they considered displayed both ingratitude and indifferent judgment. Nothing availed to change the decision he had taken and, since to each one he answered as he deemed expedient, and as each answer differed from the other, it is not easy to fix upon the particular reason which prompted him to seek his fortune in Spain.
