it is understandable that Jackson’s work should have failed to impress art historians unduly until recent times. Although he bore the brunt as an isolated prophet and special pleader between 1725 and 1754, his significance began to be appreciated only after the turn of the 20th century, first perhaps by Martin Hardie in 1906, and next and more clearly by Pierre Gusman in 1916 and Max J. Friedländer in 1917, when modern artists were committing heresies, among them the elevation of the woodcut to prominence as a first-hand art form. In this iconoclastic atmosphere Jackson’s almost forgotten chiaroscuros no longer appeared as failures of technique, for they had been so regarded by most earlier writers, but as deliberately novel efforts in an original style. The innovating character of his woodcuts in full color was also given respectful mention for the first time. But these were brief assessments in general surveys.

If the woodcut was cheaply held, it was at least acceptable for certain limited purposes. But printing pictures in color, in any medium, was considered a weakening of the fiber—an excursion into prettification or floridity. It was not esteemed in higher art circles, except for a short burst at the end of the 18th century in France and England. This was an important development, admittedly, and the prints were coveted until quite recently. They are still highly desirable. But while Bartolozzi stipple engravings or Janinet aquatints in color might have commanded higher prices than Callots or Goyas, or even than many Dürers and Rembrandts, no one was fooled. The extreme desirability of the color prints was mostly a matter of interior decoration: nothing could give a finer 18th century aura. It was not so much color printing that mattered; it was late 18th century color printing that was wanted, often by amateurs who collected nothing else.

Color prints before and after this period did not appeal to discriminating collectors except as rarities, as exotic offshoots. Even chiaroscuros, with their few sober tones, fell into this periphery. Jackson, as a result, was naturally excluded from the main field of attention.

The worship of black-and-white as the highest expression of the graphic arts1 automatically placed printmakers in color in one of two categories: producers of abortive experiments, or purveyors of popular pictures to a frivolous or sentimental public. This estimate was unfortunately true enough in most cases, true enough at least to cause the practice to be regarded with suspicion. As an indication of how things have changed in recent years we can say that color is no longer the exception. It threatens, in fact, to become the rule, and black-and-white now fights a retreating battle. A comparison of any large exhibition today with one of even 20 years ago will make this plain.

At first glance Jackson seems to be simply a belated 18th-century worker in the chiaroscuro process. If to later generations his prints had a rather odd look, this was to be expected. Native qualities, even a certain crudeness, were expected from the English who lacked advantages of training and tradition. And Jackson was not only the first English artist who worked in woodcut chiaroscuro, he was virtually the first woodblock artist in England to rise beyond anonymity2 (Elisha Kirkall, as we shall see, cannot positively be identified as a wood engraver) and he was the only one of note until Thomas Bewick arose to prominence about 1780. He was, then, England’s first outstanding woodcutter. We will find other instances of his significance from the English standpoint, but his being English, of course, would have a small part in explaining the importance of his prints.

Jackson made, in fact, the biggest break in the traditions of the woodcut since the 16th century. He broadened the scope of the chiaroscuro print and launched

the color woodcut as a distinct art form that rivaled the polychrome effects of painting while retaining a character of its own. These were not modest little pieces of purely technical interest. The set of 24 sheets reproducing 17 paintings by Venetian masters made up the most heroic single project in chiaroscuro, and the 6 large landscapes, completed in 1744, after gouache paintings by Marco Ricci, were the most impressive color woodcuts in the Western world between the 16th century and the last decade of the 19th.

But Jackson’s grand ambition to advance the woodcut beyond all other graphic media had little public or private support and finally led him to ruin. His efforts were made with insufficient means and with few patrons. As a consequence, he rarely printed editions after the blocks were cut and proofed. The Venetian set is well known because it was printed in a substantial edition. A few additional subjects were also sponsored by patrons, but most of Jackson’s other chiaroscuros were never published—they were limited to a few proofs. Editions were postponed, no doubt, in the hope that a patron would come along to pay expenses in return for a formal dedication in Latin, but this did not often happen. Most subjects exist in a few copies only; of some, single impressions alone remain. Others have entirely disappeared.

With a large part of Jackson’s work unknown, his reputation settled into an uneasy obscurity which, it must be granted, has not prevented his work from being collected. The chiaroscuros, especially the Venetian prints, can be found in many leading collections in Europe and the United States, but the full-color sheets after Ricci are excessively rare, particularly in complete sets.

Jackson has long been considered an interesting figure. His Essay on the Invention of Engraving and Printing in Chiaro Oscuro...,3 with its bold claims to innovation and merit, his adventurous career as an English woodcutter in Europe, his adaptation of the color woodcut to wallpaper printing and his pioneering efforts in this field, and Papillon’s immoderate attack on him in the important Traité historique et pratique de la gravure en bois4 will be discussed later. For the moment we can say that the Essay was the first book by an Englishman with

color plates since the Book of St. Albans of 1486, with its heraldic shields in three or four colors, and the first book with block-print plates in naturalistic colors.5

Although critics have been interested in Jackson as an historical figure, they have been uncertain about the merit of his work. Opinions vary surprisingly. Most judgments were based on the Venetian chiaroscuros and depended upon the quality of impressions, many of which are poor. Criticisms when they have been adverse have been surprisingly harsh. It is unusual, to say the least, for writers to take time explaining how bad an artist is. To do this implies, in any case, that he warrants serious attention; space in histories is not usually wasted on nonentities. We can see now that Jackson was misunderstood because the uses of the woodcut were rigidly
