the ground of the vase. "The truth of the contour being thus secured by this narrow border of ground carefully laid on the covering, the remaining surface of the vase with its varnish, might be safely entrusted to an inferior hand. That the varnish was laid on at twice, is evident by inspection of any well-finished vase, where the first narrow line of varnish is distinctly visible under the general wash. "This process finished the greater part of the vases, even the finest; but on some, particularly those of the largest size, when every thing else was quite dry, some parts of the design were coloured with washes of two different tints. The horses and parts of the armour are painted with white, which when dry is opaque, but when wetted becomes nearly transparent. Parts of the drapery and ornaments round the necks and on the heads of the figures, and some of the shields, are painted yellow, and several small flowers and ornaments of foliage, which are interspersed among the figures, are painted in white and yellow. The internal outlines and muscles of the horses are painted with lines of a light orange on the white; and the white shields are ornamented in the same manner. That the white horses were painted after the original black outline of the human figures was dry, is evidently seen in the magnificent vase in the possession of Mr. Edwards. In that vase a leg of one of the horses comes across the thigh and drapery of a figure, and the original outline of that figure is visible under the white colour which forms the horse's leg. All these colours are so fixed on the vases, probably by fire, that they resist the action of aquafortis. "The vases of the last sort, namely, those which have ornaments in white and other colours painted on a black ground, which covered the whole surface of the vase, are very rarely to be met with. Mr. Hope possesses several, which Sir William Hamilton told me were all found in one sepulchral chamber, in which none of any other sort were placed. The cause of this singularity it were vain to enquire. No figures are represented on these vases, but the ornaments are light wreathes of ivy, or vine-leaves, with masks and other bacchanalian symbols. The execution is careless, but spirited; the paint used seems of the same quality with that above described as covering the horses, &c. in vases of the third sort; and the mode of applying it appears in no wise to differ from what would be now pursued. It is not, therefore, necessary to say any thing further on this subject.
