is not without some reason. However, the other eleven stones correspond to a stone in the rational and this is the only exception. The ancients very often confounded the names of these two stones. Chalcedony is a siliceous stone. Its name is supposed to derive from Chalcedon, in Bithynia, where the ancients obtained the stone from. It is a species of agate and bears various names according to its colour. Chalcedony is usually made up of concentric circles of various colours and the most valuable of these stones are found in the East Indies. The gem is used for rings, seals and, in the East; drinking vessels. Chodchod Chodchod, kdkd (Is., liv, 12; Ezech., xxvii, 16); Sept.iaspis (Is., liv, 12), chorchor (Ezech., xxvii, 16); Vulg.jaspis (Is., liv, 12), chodchod (Ezech., xvii, 16). This word is used only twice in the Bible. Chodchod is generally identified with the Oriental ruby. The translation of the word in Is. both by the Septuagint and the Vulgate is jasper; in Ezech. the word is merely transliterated; the Greek chorchor is explained by considering how easy it is to mistake a resh for a daleth. "What chodchod signifies", says St. Jerome, "I have until now not been able to find" (Comment. in Ezech., xxvii, 16, in P. L., XXV, 255). In Is. he follows the Septuagint and translates chodchod by jaspis. The word is probably derived from phyr, "to throw fire"; the stone was therefore brilliant and very likely red. This supposition is strengthened by the fact that the Arabic word kadzkadzat, evidently derived from the same stem as chodchod, designates a bright red. It was therefore a kind of ruby, likely the Oriental ruby, perhaps also the carbuncle (see above). Chrysolite Chrysolite, Heb. trshysh (Ex., xxviii, 20; xxxix, 13; Ezech., i, 16; x, 9; xxviii, 13; Cant., v, 14; Dan., x, 6); Sept., chrysolithos (Ex., xxviii, 20; xxxix, 13; Ezech., xxviii, 13); tharsis (Cant., v, 14; Dan., x, 6); tharseis (Ezech., 1, 16; x, 9); Vulg. chrysolithus (Ex., xxviii, 20; xxxix, 13; Ezech., x, 9; xxviii, 13; Dan., x, 6), hyacinthus (Cant., v, 14); quasi visio maris (Ezech., i, 16); Apoc., xxi, 20, chrysolithos; Vulg. chrysolithus. This is the tenth stone of the rational, representing the tribe of Zebulun; it stands fourth in the enumeration of Ezech., xxviii, 13, and is given as the seventh foundation stone of the celestial city in Apoc., xxi,
