In the commentary Lorenzo wrote on some of his sonnets he not only, as in the above letter, praises Italian, but affirms its equality with the classic languages, and declares that neither Ovid, Tibullus, Catullus, or Propertius wrote love songs of such beauty and grace as Petrarch. It was by this enthusiastic participation in the intellectual pursuits and interests of his day that Lorenzo, even as a youth, attained such popularity with his fellow-citizens. They were proud of the lad who was already known as a poet, who excelled in all bodily exercises, and who was treated by foreign princes and potentates as an equal. The above letter to Federigo d’Aragona shows that he was, to quote John Addington Symonds: “A Florentine of the Florentines. Tuscan to the backbone, imbued with the spirit of his city, a passionate lover of her customs and pastimes, a complete master of her vernacular. His education, though it fitted him for Platonic discussions with Ficino and rendered him an amateur of humanistic culture, had failed to make a pedant of him. Much as he appreciated the classics, he preferred his Tuscan poets; and what he learned at school he brought to bear upon the study of the native literature.”[93] Soon after his return from Pisa Lorenzo was despatched by his father to Bologna, Ferrara, Venice, and Milan. Piero calls the journey “the touchstone of thy abilities.” The letters show that the boy of seventeen was received as a prince, and discussed with the rulers of the various states he visited important political matters, in all of which he was kept carefully informed by his father. At the same time, with characteristic Medicean shrewdness, Lorenzo was instructed to place himself in the hands of his father’s agents in each city visited, and the whole journey could be represented as a tour of inspection of the various agencies of a great banking-house, and the introduction of the heir to the business of the family.
