Pliny says the emerald was more easily counterfeited than any other gem, and considers the art of imitating precious stones a far more lucrative piece of deceit than any devised by the ingenuity of man; Egypt was, as usual, the country most noted for this manufacture; and we can readily believe that in Pliny's time they succeeded so completely in the imitation as to render it difficult to distinguish false from real stones. Many, in the form of beads, have been met with in different parts of Egypt, particularly at Thebes; and so far did the Egyptians carry this spirit of imitation, that even small figures, scarabæi, and objects made of ordinary porcelain, were counterfeited, being composed of still cheaper materials. A figure, which was entirely of earthenware, with a glazed exterior, underwent a somewhat more complicated process than when cut out of stone and simply covered with a vitrified coating; this last could, therefore, be sold at a low price; it offered all the brilliancy of the former, and its weight alone betrayed its inferiority; by which means, whatever was novel, or pleasing from its external appearance, was placed within reach of all classes, or, at least, the possessor had the satisfaction of seeming to partake in each fashionable novelty. [Illustration: IMITATION OF REAL STONES.] Such inventions, and successful endeavors to imitate costly ornaments by humbler materials, not only show the progress of art among the Egyptians, but strongly argue the great advancement they had made in the customs of civilized life; since it is certain, that until society has arrived at a high degree of luxury and refinement, artificial wants of this nature are not created, and the poorer classes do not yet feel the desire of imitating the rich, in the adoption of objects dependent on taste or accidental caprice. Glass bugles and beads were much used by the Egyptians for necklaces, and for a sort of network, with which they covered the wrappers and cartonage of mummies. They were arranged so as to form, by their varied hues, numerous devices or figures, in the manner of our bead purses; and women sometimes amused themselves by stringing them for ornamental purposes, as at the present day. A far more numerous class were the potters; and all the processes of mixing the clay, and of turning, baking and polishing the vases are represented in the tombs of Thebes and Beni Hassan, of which we have already spoken.
