The _prices_ of books in these times were considered as an object worthy of the animadversions of the highest powers. This anxiety in favour of the studious appears from a privilege of Pope Leo X. to Aldus Manutius for printing Varro, dated 1553, signed Cardinal Bembo. Aldus is exhorted to put a moderate price on the work, lest the Pope should withdraw his privilege, and accord it to others. Robert Stephens, one of the early printers, surpassed in correctness those who exercised the same profession.[35] To render his editions immaculate, he hung up the proofs in public places, and generously recompensed those who were so fortunate as to detect any errata. Plantin, though a learned man, is more famous as a printer. His printing-office was one of the wonders of Europe. This grand building was the chief ornament of the city of Antwerp. Magnificent in its structure, it presented to the spectator a countless number of presses, characters of all figures and all sizes, matrixes to cast letters, and all other printing materials; which Baillet assures us amounted to immense sums.[36] In Italy, the three Manutii were more solicitous of correctness and illustrations than of the beauty of their printing. They were ambitious of the character of the scholar, not of the printer. It is much to be regretted that our publishers are not literary men, able to form their own critical decisions. Among the learned printers formerly, a book was valued because it came from the presses of an Aldus or a Stephens; and even in our own time the names of Bowyer and Dodsley sanctioned a work. Pelisson, in his history of the French Academy, mentions that Camusat was selected as their bookseller, from his reputation for publishing only valuable works. "He was a man of some literature and good sense, and rarely printed an indifferent work; and when we were young I recollect that we always made it a rule to purchase his publications. His name was a test of the goodness of the work." A publisher of this character would be of the greatest utility to the literary world: at home he would induce a number of ingenious men to become authors, for it would be honourable to be inscribed in his catalogue; and it would be a direction for the continental reader. So valuable a union of learning and printing did not, unfortunately, last. The printers of the seventeenth century became less charmed with glory than with gain. Their correctors and their letters evinced as little delicacy of choice.
