Louis, by the grace of God King of France. We make known to all present and for the future: Bearing in mind the great, praiseworthy, and much to be commended fame enjoyed by the late Cosimo de’ Medici during his life in all his actions and his affairs, which he conducted with such great virtue and prudence that his children and other relatives and friends must be commended and held in high honour. For these reasons and moved by the supplication and prayer which has been addressed to us by our friends, and by our loyal Councillor Piero de’ Medici, son of the said late Cosimo de’ Medici, we by our own will, special grace, full power and royal authority decree and command by these presents that the said Piero de’ Medici ... his heirs and successors born and to be born in legal wedlock may henceforward and for ever have and bear in the arms three Fleur de lis of the shape and manner herein portrayed.... And these arms we have given and give to them by these said presents, to use as seems good to them in all places and among all people, in time of peace or in time of war, without any impediment either now or hereafter being placed to their so doing. And in order that this thing should be firm and stable for ever, we have caused our seal to be set to these two presents, reserving our rights in all other things and our authority in everything.--Given at Mont Luçon in the month of May, the year of grace 1465, and the fourth year of our reign.[90] Owing to Piero’s miserable health, his son Lorenzo was sent, even as quite a lad, to visit foreign courts and to receive foreign princes who passed through Tuscany. Thus in April 1465 he met Don Federigo d’Aragona, second son of the King of Naples, at Pisa, on his way to Milan to escort his eldest brother’s bride, Ippolita Maria, daughter of Francesco Sforza, to Naples. The two youths formed a lasting friendship, and on Federigo’s return with his sister-in-law they came to Florence and stayed in the Medici palace. Ippolita and Lorenzo then became such friends that she never hesitated to appeal to him when, as often happened in the needy Neapolitan court, she wanted money. They often corresponded, and when Lorenzo went to Naples in 1479, the Duchess of Calabria and Don Federigo were his powerful allies. The following letter, a remarkable one for a lad of seventeen, was sent to Don Federigo with a volume of poems selected from those writers Lorenzo considered to be masters of the Tuscan tongue. There are two copies in Florence, one in the Nazionale Library,[91] the other in the Riccardiana.[92] _The Magnificent_ Lorenzo to the Illustrious Lord Federigo, _son of the King of Naples_
