'Mr. Roscoe has observed that "by no circumstance in the character of an individual is the love of literature so strongly evinced as by the propensity for collecting together the writings of illustrious scholars, and compressing the 'soul of ages past' within the narrow limits of a library." But it is not easy now to appreciate the obstacles attending such a pursuit in the age of Federigo. The science of bibliography can scarcely be said to have existed before the invention of printing, in consequence of the extreme difficulty of becoming acquainted with works of which there were but few copies, and these widely scattered, perhaps scarcely known. Great outlay was required, either to search out or transcribe manuscripts, and even the laborious habits which then accompanied learning shrank from a task so beset by obstructions. Yet there was a bright exception in Thomas of Saranza, whose learning supplied the knowledge, and whose elevation to the triple tiara as Nicholas V. procured him the opportunities necessary for amassing a library. Not only did he found that of the Vatican, but he prepared for Cosimo, Pater patrie, a list of authors for the infant collection of S. Marco, at Florence, which, being recognised as a standard catalogue, was adopted by Count Federigo. The longer life allowed to the latter enabled him to outstrip these bibliomaniacs, and all contemporary accumulators, until the fame of his library stood unrivalled. Accordingly Ruscelli, in his Imprese Illustri, avers it to be "notorious that the earliest and most famous collection formed out of the ruins of antiquity was that of Urbino, from whence many excellent authors were edited, and copies supplied."'[66]

'In no respect did he look to expense; and whenever he learned the existence of any desirable book in Italy, or abroad, he sent for it without heeding the cost. His librarian, Vespasiano, wrote, "It is now above fourteen years since he began to make this collection, and he has ever since at Urbino, Florence, and elsewhere, thirty-four transcribers, and has resorted to every means requisite for amassing a famous and excellent library."'[67]

'To the right and left of the carriage entrance into the great courtyard, are two handsome saloons, each about forty-five feet by twenty-two, and twenty-three in height. That on the left contained the famous library of manuscripts collected by Count Federigo; the corresponding one received the printed books, which, gradually purchased by successive dukes, became under the last sovereign, a copious collection. Baldi, in his description of the palace, printed in Bianchini's work, dwells on the judicious adaptation of the former, its windows set high against the northern sky, admitting a subdued and steady light which invited to study; its air cool in summer, temperate in winter; its walls conveniently shelved; the character and objects of the place fittingly set forth in a series of rude hexameters inscribed on the cornices. Adjoining was a closet fitted up with inlaid and gilded panelling, beneath which Timoteo della Vite, a painter whose excellence we shall attest in our thirtieth chapter, depicted Minerva with her Ægis, Apollo with his lyre, and the nine muses with their appropriate symbols. A similar small study was fitted up immediately over this one, set round with arm-chairs encircling a table, all mosaicked with tarsia, and carved by Maestro Giacomo of Florence, while on each compartment of the panelling was the portrait of some famous author, and an appropriate distich. One other article of furniture deserves special notice—a magnificent eagle of gilt bronze, serving as a lectern in the centre of the manuscript room. It was carried to Rome at the devolution of the duchy to the Holy See, but was rescued by Pope Clement XI. from the Vatican library, and restored to his native town, where it has long been used in the choir of the cathedral.'[68]

'Of Francesco Maria's literary pursuits we have various pleasing memorials. Not satisfied with the valuable library of MSS. that had descended to him from the Feltrian dukes, he formed another of standard printed works. Indeed, he became an assiduous book-collector; and the letters of his librarian, Benedetto Benedetti, in the Oliveriana Library, are full of lists which his agents in Venice, Florence, and even Frankfort are urged to supply. In his own voluminous correspondence, we find constant offers from authors of dedications or copies of their productions, the tone of which is highly complimentary to his taste for letters. In 1603, the Archbishop of Monreale, in Spain, transmits him the regulations he proposed to prescribe in bequeathing his library to a seminary he had founded in his diocese, expressing a hope that they might prove useful to the Duke's collection, "at this moment without parallel in the world." Instead of quoting the vague testimony of courtly compliment, as to the use which this philosophic Prince made of these acquisitions, let us cite the brief records of his studies, preserved in his own Diary. In 1585, "terminated an inspection of the whole works of Aristotle, on which I have laboured no less than fifteen years, having had them generally read to me by Maestro Cesare Benedetti, of Pesaro."'[69]

'Francesco di Giorgio, in his Treatise on Architecture, mentions Duke Federigo as holding out inducements for the learned men at his court to illustrate the works of classic authors on architecture and sculpture. But no testimony to his literary habits can be more satisfactory than that of his librarian, Vespasiano, to the following purpose. The Duke was a ready Latin scholar, and extremely fond of ancient history. As a logician he had attained considerable aptitude, having studied Aristotle's Ethics along with Maestro Lazzaro, a famous theologian, who became Bishop of Urbino, discussing with him the most intricate passages. By the like process he mastered the Stagirite's politics, physics, and other treatises; and having acquired more philosophy than any contemporary prince, his thirst for new sources of knowledge induced him to devote himself to theology with equal zeal. The principal works of St. Thomas Aquinas and Duns Scotus were habitually read to him; he preferred the former as more clear, but admitted that the latter displayed more subtlety in argument. He was well acquainted with the Bible, as well as the commentaries of Saints Ambrose, Jerome, Augustine, and Gregory; also with the writings of the Greek fathers, such as Saints Basil, Chrysostom, Gregory Naziazen, Nicetas, Athanasius, and Cyril. Among the classic authors whom he was in the habit of reading or listening to were Livy, Sallust, Quintus Curtius, Justin, CÆsar, Plutarch, Ælius Spartianus, Æmylius Protus, Tacitus, Suetonius, Eusebius. All men of letters visiting Urbino were hospitably entertained, and several were always attached to his court. His largesses to such were at all times liberal. He spent above 1500 ducats in this way when at Florence, and remitted similar bounties to Rome and Naples. He gave 1000 ducats to the learned Campano, professor of belles-lettres at Perugia in 1455, who aided him in collecting ancient MSS., and became Bishop of Teramo.'[70]
