The term scarlet as employed in the Old Testament was used to designate the blood-red color procured from an insect somewhat resembling cochineal, found in great quantities in Armenia and other eastern countries. The Arabian name of the insect is Kermez (whence crimson). It frequents the boughs of a species of the ilex tree: on these it lays its eggs in groups, which become covered with a sort of down, so that they present the appearance of vegetable galls or excrescences from the tree itself and are described as such by Pliny XVI, 12, who also gave it the name of granum, probably on account of its resemblance to a grain or berry, which has been adopted by more recent writers and is the origin of the term "ingrain color" as now in use. The dye is procured from the female grub alone, which, when alive is about the size of the kernel of a cherry and of a dark red-brown color, but when dead, shrivels up to the size of a grain of wheat and is covered with a bluish mold. It has an agreeable aromatic smell which it imparts to that with which it comes into contact. It was first found in general use in Europe in the tenth century. About 1550, cochineal, introduced there from Mexico, was found to be far richer in coloring matter and therefore gradually superseded the older dyestuff. Indigo was used in India and Egypt long before the Christian era; and it is asserted that blue ribbons (strips) found on Egyptian mummies 4500 years old had been dyed with indigo. It was introduced into Europe only in the sixteenth century. The use of madder as a red dyestuff dates from very early times. Pliny mentions it as being employed by the Hindoos, Persians and Egyptians. In the middle ages the names sandis, warantia, granza, garancia, were applied to madder, the latter (garance) being still retained in France. The color yielding substance resides almost entirely in the roots. Chilzon was the name given by the ancient Hebrews to a blue dye procured from a species of shell-fish. Herodotus, B. C. 443, asserts that on the shores of the Caspian Sea lived a people who painted the forms of animals on their garments with vegetable dyes: "They have trees whose leaves possess a peculiar property; they reduce them to powder, and then strip them in water; this forms a dye or coloring matter with which they paint on their garments the figures of animals. The impression is such that it cannot be washed out; it appears, indeed, to be woven into the cloth, and wears as long as the garment itself."
