Of the two great book-finders, Guarino and Poggio, the latter,[438] on the occasion of the Council of Constanz and acting partly as the agent of Niccoli, searched industriously among the abbeys of South Germany. He there discovered six orations of Cicero, and the first complete Quintilian, that of St. Gall, now at Zürich; in thirty-two days he is said to have copied the whole of it in a beautiful handwriting. He was able to make important additions to Silius Italicus, Manilius, Lucretius, Valerius, Flaccus, Asconius, Pedianus, Columella, Celsus, Aulus, Gellius, Statius, and others; and with the help of Lionardo Aretino he unearthed the last twelve comedies of Plautus, as well as the Verrine orations, the ‘Brutus’ and the ‘De Oratore’ of Cicero. The famous Greek, Cardinal Bessarion,[439] in whom patriotism was mingled with a zeal for letters, collected, at a great sacrifice (30,000 gold florins), 600 manuscripts of pagan and Christian authors. He then looked round for some receptacle where they could safely lie until his unhappy country, if she ever regained her freedom, could reclaim her lost literature. The Venetian government declared itself ready to erect a suitable building, and to this day the library of St. Mark retains a part of these treasures.[440] The formation of the celebrated Medicean library has a history of its own, into which we cannot here enter. The chief collector for Lorenzo Magnifico was Johannes Lascaris. It is well known that the collection, after the plundering in the year 1494, had to be recovered piecemeal by the Cardinal Giovanni Medici, afterwards Leo X.
