On an examination of delft earthenware of the period and Dutch decorative art in general, it is fairly obvious that the art impulses coincide with the various phases of ornament as found on the marquetry panel, whether they were the floriated designs of Italy with the vase and the symmetrical flowers in conventional form, further conventionalized by the Dutch, who clung to tulips and carnations, or the arabesque designs derived from the Dutch traffic with the East Indies, the pseudo-Persian sherbet tray as a panel, the prayer rug as a full design. With his black delft to imitate lacquered work of Japan and his blue delft to imitate the Kang-he Chinese porcelain, the Dutchman proved himself a superlative translator. The Dutch East India Company, till it was supplanted, was the conduit-pipe through which the arts of the East were allowed to pass into Europe. In another portion of this volume we show how apparently obscure ornament has a long lineage, and that craftsmen in minor details were producing something of which possibly they knew not the origin nor the significance; but it behoves the intelligent collector, who, after all, is in possession of more facts, spread over a wider area, to arrive at sane conclusions in regard to workers who wrought better than they thought. =The Wall-paper Period.=--It was a sad time when the idea originated to make wall-paper simulate marble or tapestry or leather, or anything else. Wall-hangings made of paper by the Chinese came into England in the early seventeenth century. But European wall-paper is a modern abomination. Chintz has a better excuse to imitate satin. "Callicoes" were tabooed at first, but they had and have a legitimate place. Wall-paper is an affectation which cannot be defended. It always pretends to be what it is not. It is really wonderful that amateurs did not paste it over clock-cases. Perhaps they did, and other persons, wiser in their generation, removed it. But if wall-paper of the late seventeenth and early eighteenth centuries was not affixed to the clock-case, it was there in spirit, as it was on strident bureaus and other equally offensive articles of the period. The "all-over" style exhibits marquetry run mad. Artisans could apply the thin veneer, ten sheets to the inch, like paper, and they did. They had borders as common as modern factory-made imitation lace at a few pence per yard, and they laid them beside the pilasters and around the already well covered case. There was no square inch that could be said to be free from the attentions of the gluer of marquetry sheets. He began to dominate decoration till happily he was extinguished.
