Purple is well known to have been a color of high repute. Moses, under Divine instruction, used purple stuffs for the furniture of the tabernacle and the dress of the high-priest. Purple raiment was worn by the kings of Midian; and a garment of fine linen and purple was given to a favorite by the Monarch Ahasuerus, whose palace was furnished with curtains of this color, on a pavement of red, and blue, and white marble. The Jews made a decree that Simon should wear purple and gold, in token that he was their chief magistrate; and that none of the people should wear purple or a buckle of gold, without his express permission. And Homer thus describes a king— “In ample mode, A robe of military purple flowed o’er all his frame.” There is a story that the celebrated Tyrian dye was discovered by accident. A dog having broken one of the shells of the rock-whelk, stained his mouth with the color it contains, and thus led to the examination of this mollusc. It was then found that near to the head, and lying in a little furrow, is a white vein, yielding the beautiful purple tint which was long so highly esteemed. It might be supposed that such processes as that of dyeing could only be conducted in an advanced state of society; but to this it is not exclusively confined. There is no doubt that, even during the captivity in Egypt, the Israelitish women became acquainted with them. For scarcely had they entered the wilderness than we hear that “the wise-hearted among them” did not only “spin with their hands,” but “brought that which they had spun, both of blue, and of purple, and of scarlet,” as well as “of fine linen.” We even find another process analogous to dyeing, in circumstances in which we should not expect it to be discovered. In some of the islands of the South Sea elegant small ferns grow in abundance, and with these the native women impress figures, in divers colors, upon their cloth—literally, a method of printing, which is but one remove below the boasted invention of the Chinese, by means of engraven blocks, before the art was discovered in Europe. Its resemblance to calico printing is even more striking. For the old method, still continued for certain parts of the work, were by blocks of sycamore, on the surface of which the pattern was cut in relief, in the common method of wood engraving.
