90	GARNETS
	garnets. As all these stones in ancient times were cut in the round shape, the name has come down to us as carbuncle, and its association with the garnet has always been preserved. However, scientifically carbuncle refers merely to the shape of the stone, and not at all to its composition or mineralogical variety. The garnet is one of the oldest stones known. In some of the most ancient mummies dis­covered in Egypt are found necklaces and other jewels containing garnets. And under the name carbuncle the garnet is mentioned in the literature of all ages, being valued chiefly for the brilliant fiery light which it gives forth. According to the Talmud, the only light which Noah had in the Ark was afforded by a car­buncle.
