Four years after his arrival in Rome, a Milanese noble, Bartolomeo Scandiano, who later went as nuncio to Spain, invited Peter Martyr to pass the summer months in his villa at Rieti, in company with the Bishop of Viterbo. In the fifteenth letter of the _Opus Epistolarum_ he recalls the impressions and recollections of that memorable visit, in the following terms: "Do you remember, Scandiano, with what enthusiasm we dedicated our days to poetical composition? Then did I first appreciate the importance of association with the learned and to what degree the mind of youth is elevated in the amiable society of serious men: then, for the first time, I ventured to think myself a man and to hope that I might become somebody." The summer of 1481 may, therefore, be held to mark his intellectual awakening and the birth of his definite ambitions. Endowed by nature with the qualities necessary to success, intimate association with men of eminent culture inspired him with the determination to emulate them, and from this ideal he never deflected. The remaining six years of his life in Rome were devoted to the pursuit of knowledge, and in the art of deciphering inscriptions and the geography of the ancients he acquired singular proficiency. 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.
