Later, more mature judgment has made it plain that his contributions as a craftsman outrank his worth as an artist. He was no Holbein, no Botticelli--it is absurd to think of him in such terms--but he did develop a fresh method of handling wood engraving. Because of this he represents a turning point in the development of this medium which led to its rise as the great popular vehicle for illustration in the 19th century. In his hands wood engraving underwent a special transformation; it became a means for rendering textures and tonal values. Earlier work on wood could not do this; it could manage only a rudimentary suggestion of tones. The refinements that followed, noticeable in the highly finished products of the later 19th century, came as a direct and natural consequence of Bewick's contributions to the art. Linton[4] and a few others object to the general claim that Bewick was the reviver or founder of modern wood engraving, not only because the art was practiced earlier, if almost anonymously, and had never really died out, but also because his bold cuts had little in common with their technician's concern with infinite manipulation of surface tones, a feature of later work. But this misses the main point--that Bewick had taken the first actual steps in the new direction. [4] William Linton, _The masters of wood engraving_, London, 1889, p. 133. [Illustration: Figure 1.--Woodcutting Procedure, showing method of cutting with the knife on the plank grain, from Jean Papillon's _Traité de la gravure en bois_, 1766.] Unquestionably he gave the medium a new purpose, even though it was not generally adopted until after 1830. Through his pupils, his unrelenting industry, and his enormous influence he fathered a pictorial activity that brought a vastly increased quantity of illustrations to the public. Periodical literature, spurred by accompanying pictures that could be cheaply made, quickly printed, and dramatically pointed, became a livelier force in education. Textbooks, trade journals, dictionaries, and other publications could more effectively teach or describe; scientific journals could include in the body of text neat and accurate pictures to enliven the pages and illustrate the equipment and procedures described. Articles on travel could now have convincingly realistic renditions of architectural landmarks and of foreign sights, customs, personages, and views. The wood engraving, in short, made possible the modern illustrated publication because, unlike copper plate engraving or etching, it could be quickly set up with printed matter. Its use, therefore, multiplied increasingly until just before 1900, when it was superseded for these purposes by the photomechanical halftone.
