belonged to the court of Urbino; meanwhile we may mention a few works dedicated to Federigo by learned men in other parts of Italy, from which it would seem that the rival systems of Plato and Aristotle shared his attention and patronage. [Footnote *176: Dennistoun does not seem to be acquainted with the _Ode lirica a Federigo di Montefeltro_ (Per Nozze. Roma Tip. della Camera dei Dep., 1899), which Francesco Filarete wrote to him after the conquest of Volterra in 1472. It was possibly spoken at Florence in 1474, when Federigo became Duke. It speaks (strofe 14) of Federigo's early campaigns with Nicolò Piccinino, without hiding (strofe 16) the disaster of Monteluro and the rout of Montelocco (strofe 17), and goes on to tell of the Tuscan campaign of King Alfonso and the retaking of Fossombrone (strofe 26), and so forth.] Ptolemy's geography was translated into Latin verse by Berlinghieri, who inscribed to Federigo the result of his ill-bestowed toil, in a splendid MS., richly illuminated, which remains in the Brera library. The published work was also issued in 1480, under sanction of his name, as was the translation of another work of Ptolemy by Pontano. To these Baldi adds Marsilio Ficino's _Epistles on the Platonic Theology_ and translation of Plato's _Dialogue de Regno_, Alemanno Rinuccini's translations of Aristotle and Philostratus, Paolo Marso's Commentary upon the _Fasti_ of Ovid, Nicolò Perotto's _Cornucopia_, Poggio's _Historia Populi Florentini_, as specimens of a catalogue which might be greatly lengthened.[177] In the volume of his own MS. letters already often quoted, we find him thanking Naldo of Florence for his poem on the Volterran expedition, and acknowledging the _Disputationes Camaldulenses_ of Cristoforo Landino. Writing to Donato Acciaiuolo, he avows the pleasure and advantage derived from perusing his Commentaries on a book of ethics, and expresses satisfaction that he had succeeded in persuading him to undertake a similar work on politics, for which he thanks him in a subsequent letter, apologising for having detained his messenger until he had read a great portion of it with the utmost pleasure, and enjoining reliance on his friendship and services.[178] [Footnote 177: Vat. Urb. MSS. No. 1198.] [Footnote 178: Several of these MSS. I have found in the Laurentian library at Florence.] Before leaving the subject of dedications, we may quote the following singular illustration of literary history. "To the Lord and most excellent Captain-at-arms, the Lord Federigo of Montefeltro, Count of Urbino, Lord of Gubbio, and most illustrious Captain-general of the League, our especial Lord, &c.; the Priors of Arezzo.
