The name of this stone is derived from Chalcedon, where it is said to have been first discovered. In modern mineralogy this is the name of an agate-like quartz of a bluish colour. Pliny so names the Indian ruby. The mineral intended in Revelation is probably the Hebrew nophekh, translated “emerald” (Ex. 28:18; 39:11; Ezek. 27:16; 28:13). It is rendered “anthrax” in the LXX., and “carbunculus” in the Vulgate.
