At this epoch engravings from the burin were taken with a pale ink, the composition of which is very different from the fine black ink of Schoeffer as well as of the old Italian printers. And besides in most cases the proofs were obtained with the _frotton_, like the ancient block books, an eminently defective process. The press was not yet well adapted to the delicate work of line engraving, and the workmen, who did not apply the plates until after the text was printed, preferred not to risk the loss of their sheets by the use of inappropriate presses. These, with the insignificant attempts made by the Germans in 1479,[A] are the beginnings of the process of line engraving in the ornamentation of the Book. In fact, the process failed to take its due position for want of a more convenient mode of working. Relief engraving had got ahead; with it the sheets used for the impression did not require working more than once to register the figures with the text; in a word, the labour was not so great. A century had to pass before line engraving completely dethroned the vignette on wood, a century in which the latter attained its height, and showed what able artisans could make of a process apparently the least flexible.

Dold., 1479, folio, copper plate engravings.] Not to leave Italy, which had the honour of making the book with engraved illustrations known to the world, we pass by some years, during which Arnold Bucking gave at Rome a _Cosmographia_ of Ptolemy, 1478, with incised plates, which is the first printed atlas that was produced, whilst as regards ordinary publications there appeared in all parts classical and Italian works, such as Cicero, Virgil, Tacitus, Pliny, Eusebius, among the ancients, and Dante, Petrarch, Boccaccio, etc., among moderns. Among the editions of Dante, we may cite that of Peter of Cremona, dated 18th November, 1491, with one engraving to each canto, of which the earlier are after Botticelli, and perhaps drawn by him directly on the wood. Passavant believes these figures to be cut in relief in the metal. On some of the plates there is a signature, a Gothic b, the signification of which leaves a free field for conjecture, and perhaps for error. Copies of this book with the complete series of twenty plates are extremely rare; one in the Hamilton Palace Library sold in May, 1884, for £380; the Royal Library of Berlin recently agreed to pay £1,200 for a proof set of the plates.
