From Webster's Revised Unabridged Dictionary (1913) [web1913]: Copper \Cop"per\, n. [OE. coper (cf. D. koper, Sw koppar Dan. kobber, G. kupfer), LL cuper, fr L. cuprum for earlier Cyprium Cyprium aes, i.e., Cyprian brass, fr Gr ? of Cyprus (Gr. ?), anciently renowned for its copper mines.

It is one of the most useful metals in itself and also in its alloys, brass and bronze. Note: Copper is the only metal which occurs native abundantly in large masses; it is found also in various ores, of which the most important are chalcopyrite, chalcocite, cuprite, and malachite. Copper mixed with tin forms bell metal; with a smaller proportion, bronze; and with zinc, it forms brass, pinchbeck, and other alloys. 2.

Opposed to {light pipe} or say a short-range microwave link. [{Jargon File}] (1994-11-30) From Elements database 20001107 [elements]: copper Symbol: Cu Atomic number: 29 Atomic weight: 63.54 Red-brown transition element. Known by the Romans as 'cuprum.'

From Easton's 1897 Bible Dictionary [easton]: Copper derived from the Greek kupros (the island of Cyprus), called "Cyprian brass," occurs only in the Authorized Version in Ezra 8:27. Elsewhere the Hebrew word nehosheth is improperly rendered "brass," and sometimes steel" (2 Sam. 22:35; Jer. 15:12). The "bow of steel" (Job 20:24; Ps 18:34) should have been "bow of copper" (or "brass," as in the R.V.). The vessels of "fine copper" of Ezra 8:27 were probably similar to those of "bright brass" mentioned in 1 Kings 7:45; Dan. 10:6. Tubal-cain was the first artificer in brass and iron (Gen. 4:22). Hiram was noted as a worker in brass (1 Kings 7:14). Copper abounded in Palestine (Deut. 8:9; Isa. 60:17; 1 Chr. 22:3, 14). All sorts of vessels in the tabernacle and the temple were made of it (Lev. 6:28; Num. 16:39; 2 Chr. 4:16; Ezra 8:27); also weapons of war (1 Sam. 17:5, 6, 38; 2 Sam. 21:16). Iron is mentioned only four times (Gen. 4:22; Lev. 26:19; Num. 31:22; 35:16) in the first four books of Moses, while copper (rendered "brass") is mentioned forty times. (See {BRASS}.) We find mention of Alexander (q.v.), a coppersmith" of Ephesus (2 Tim. 4:14).
