Before leaving the year 1469, we should mention the first Italian instance of a printed translation of a Greek classic, the Italian Strabo, published by Sweynheym and Pannartz without date, but which is known to have belonged to this year. In 1470 the run on classics continues, the same number as in the previous year being printed, mostly by Sweynheym and Pannartz, but a revival is apparent in other branches of literature, the number of books in theology being nearly equal to that of the classics. Another translation from the Greek appears, that of Plutarch's Lives, rendered by various hands, with the preface of J. A. Campanus. The most remarkable production of the Roman press for this year, however, is a small tract, which affords the first example of recourse to printing by a Pope for an official purpose. It is the brief of Pope Paul II., enacting that the Jubilee shall henceforth be celebrated every twenty-fifth year, and consequently in 1475, which he did not live to see. This interesting document has been recently acquired by the British Museum. In 1471, as is most probable, another Government publication appeared, "The Civic Statutes of Rome," as revised by Paul II.; and the election of his successor Sixtus, in the same year, produced the first two examples of official publications, afterwards very frequent, the congratulatory harangues pronounced by ambassadors upon occasion of their tendering homage to the Pope.
Twelve classical publications grace the year, mostly from the press of Sweynheym and Pannartz, as well as the first volume of their great edition of the "Biblical Commentary" of Nicolaus de Lyra. The remaining four volumes appeared in the year following, and the last was freighted with the memorable appeal to Pope Sixtus IV., composed by the Bishop of Aleria in the name of the printers, which throws so vivid a light on the vicissitudes of the book-trade in Rome. They have printed 12,475 sheets, _acervum ingentem_, for which it is marvellous that paper or types should have been found. Their spacious premises are choked with unbound sheets in quinions (_quinterniones_), but void of victual and drink. Will the Pope give them some little office, by aid of which they may be able to provide for themselves and their families? Rome was manifestly no place for classical publishers, even under a Pope who did so much for the encouragement of learning as Sixtus. The forlorn estate of Sweynheym and Pannartz, contrasted, as we shall see, with the flourishing condition of the Venetian book-trade at the time, shows that even at a period when reading, to say nothing of the scholarship required to master the literature of the day, was not a general accomplishment, the bookseller's best patron was the public. Probably, however, the hardships of the firm may have been somewhat exaggerated by the eloquent pen of the Bishop of Aleria; for in this very year they appear as printing ten books, and in the following year seven. Two of these are new editions of works previously issued by them, showing not only that the original impression was sold out, but that it was thought profitable to undertake another.
