THE COPPER AGE.
Copper was abundantly produced in Europe, and the pure metal was used throughout the continent with the exception of Scandinavia, where specimens are exceedingly rare. The iron age of Denmark begins with the Christian era, and was preceded only by bronze and stone. We know nothing of the discovery of copper in Ireland. It is supposed in legend to have been introduced by the Fir-bolgs (bag-men, Belgæ?), or by the Tuatha (gens) de Danaan (the Danes?). These oft-quoted races, known to us only by name, have been affiliated with a host of continentals, even with the Greeks.[203] It would be mere guess-work to consider the Irish style of treating the ores—by spalling or breaking the stone, by wasting, fluxing, or smelting. We have, however, many specimens which explain the casting. The metal was called by the natives Uma or Umha, a Keltic word; also Dearg Umha, red copper, opposed to Ban[204] Umha (white copper) or tin; and this term afterwards became ‘stan,’ evidently from stannum (Gall. Estain). There are still traditions of copper mines having existed at an early period; and, among the wonders related by Nonnius (Archæol. Soc. Ireland), we find Loch Lein, now Killarney, surrounded by four circles of copper, tin, lead, and iron. Of late years ‘miners’ hammers,’ the native name for stone pounders, have been dug up in the neighbourhood of that lake, in Northern Antrim, at an ancient mine in Ballycastle, and in sundry parts of Southern Ireland.[205] The metal occurs in small quantities at Bonmahon (Waterford); copper and cobalt at Mucross, and grey copper ore in Cork, Kerry, Tipperary, and Galway. In 1855 some 1157 tons were shipped to Swansea.
The Greenlanders and Eskimos cut and hammer their pure native copper, without smelting, into nails, arrow-piles, and other tools and weapons. Mackenzie (second voyage) tells us that pure copper was common among the tribes on the borders of the Arctic Sea, whose arrow-heads and spear-heads were cold-wrought with the hammer. Columbus (fourth voyage), before touching the mainland of Honduras, saw at Guanaga Island a canoe from Yucatan[206] laden with goods, amongst which he specifics ‘copper hatchets, and other elaborate articles, cast and soldered; forges, and crucibles.’[207] At Hayti the great Admiral (first expedition) had mentioned masses of native copper weighing six arrobas (quarters).[208] When the Spaniards first entered the province of Tupan they mistook the bright copper axes for gold of low touch, and bought with beads some six hundred in two days:[209] Bernal Dias describes these articles as being very highly polished, with the handle curiously carved, as if to serve equally for an ornament and for the field of battle.
COPPER IN AMERICA.
In North America there are two great copper regions which supplied the whole continent[210]—Lake Superior and the lower Rio Grande. The former shows the first transitional steps from stone to metal. The ore occurs in the igneous and trappean rocks that wall in the vast fresh-water sea, and is found in solid blocks: one, fifty feet long, six feet deep, and six feet in average thickness, was estimated to weigh eighty tons. At Copper Harbour, Kawunam Point, a single vein yielded forty thousand pounds. The largest mass in the Minnesota Mine (Feb. 1857) occupied Mr. Petherick and forty men for twelve months: it was forty-five feet long, thirty-two feet broad (max.), and eight feet thick; containing over forty per cent. ore, and weighing four hundred and twenty to five hundred tons. Malleable and ductile, representing an average of 3·10 per cent. native silver, and with a specific gravity of 8·78 to 8·96, it required no crucible but Nature’s; it wanted only beating into shape, and it needed nothing of the skilled labour necessary for the ores of Cornwall and Devon, which contributed so largely to the wealth of Tyre. The workings are supposed to belong to the race conveniently called ‘Mound-builders,’ and to date from our second century, when the Damnonians of Cornwall were in a similar state of civilisation. ‘Cliff Mine’ supplied fine specimens of weapons and tools, arrow-piles and spear-heads, knives and three-sided blades like the old bayonet. The socket was formed by hammering flat the lower end, and by turning it over partially (without overlapping) at each side, so as to make a flange. Professor James D. Butler (‘Prehistoric Wisconsin’) facsimiles twenty-four copper implements. The ‘Indians’ called the metal Miskopewalik (red iron), opposed to black iron. As is also proved by the Brockville relics, the people had the art of hardening copper.
The mines of the lower Rio Grande supplied Mexico with materials for arms and tools. According to Captain R. H. Bonnycastle,[211] the metal was found in New Mexico and in the volcanic rocks of Mechoacan (Valladolid, New Spain). Mexico, like Peru, used the crucible and added bronze to copper. The metals were under the god Quetzalcoatl, an Aztec Tubal Cain-ben-Lamech.
Another great centre of the Copper Age was the land ‘where men got gold as they do iron out of Biscay.’ The Peruvian army, a host of three hundred thousand levied from a total population of twenty millions, was armed with bows and arrows, clubs, pikes, javelins, war-axes (of stone and copper), and the paddle-sword;[212] while the people of Anahuac (Mexico) had bows and spears, clubs and axes, knives and Swords one-handed and two-handed, the Mahquahuitl set with obsidian teeth. In the former country the pre-Ynkarial Aymaras, who dug for gold and silver, copper and tin, and who employed alloys, almost ignored for their ‘Ayri’ (cutting implements) the use of iron and steel, which they called Quella (Khellay). The Andes range is popularly derived from the Quichua word Anta[213] (copper): the native ore occurred in the parts above the cultivation-line, and it abounded in the cupriferous sandstones of Bolivian Corocoro. The Huaunanchuco country (Rivero and Tschudi, p. 203),[214] conquered by the ninth Ynka, produced a fine collection of stone and copper axes, chisels, pins, and tweezers. Blas Valera, one of the earliest writers, still often quoted, tells us that ‘Anta’ served in place of iron, and that the people worked it more than other ores, preferring it to gold (Khori) and silver.[215] Of it were made their knives, carpenters’ tools, women’s dress-pins (Tupies), polished mirrors, and ‘all their rakes and hammers.’ Garcilasso de la Vega adds: ‘pikes, clubs, halberts, and pole-axes,[216] made of silver, copper, and some of gold, the “tears of the sun,” having sharp points, and some hardened by the fire’; also carpenters’ axes; adzes and hatchets; bill-hooks of copper, and blow-pipes of the same metal about a yard long applied to earthen or clay pots which they carried from place to place. A nugget or loose pebble acted as bell-clapper, and copper statuettes were coated or plated with precious metals. The ‘Royal Commentaries of the Yncas’ tells us that copper served in place of iron for making weapons of war: the people valued it highly because more useful than gold and silver; the demand was greater than for any other metal, and it paid tribute (vol. i. pp. 25, 43, 48). We find notices of copper hammers, bellows-nozzles, adzes, axes, and bill-hooks (i. p. 102). Cieza de Leon (chap. lxiii.) tells us that the Peruvians placed a piece of gold, silver, or copper in the corpse’s mouth. He mentions vases of copper and of stone (chap. civ.), and small furnaces of clay where they laid the charcoal and blew the fire with thin canes instead of bellows (ibid.). The Introduction (p. lii) notes the Peruvian use of copper-trowels for smoothing and polishing walls, and a ‘terrible weapon of copper in the shape of a star.’ According to Rivero and Tschudi (chap. ix.) the Peruvians could not work copper as well as gold or silver; yet they made idols, vases, solid staves a yard long with serpents inlaid, and sceptre-heads decorated with condor-like birds. The household vaisselle of the Ynkas consisted of gold and silver, copper and stone. Rivero, analysing Peruvian weapons and tools (hatchets and chisels), found from five to ten per cent. silica: he could not determine whether it was an artificial or an accidental impurity. Tschudi (1841) discovered copper arms in a tomb three leagues from Huaco, and established the fact that the Peruvians used the paddle-sword and the scymitar.[217] A copper axe, found in a Huaca (old grave) at the now well-known Arica, was associated with a thong-sling and with other primitive instruments.
The people of New Granada, according to the tale of Bollaert,[218] ‘gilt’ their copper by ‘rubbing the juice of a plant on it and then putting it into the fire, when it took the gold colour’—a process which reminds us of Pliny’s ox-gall varnish. Ecuador forged copper nippers for tweezers. The Chitchas, or Muiscas (i.e. men), of Bogota, who knew only gold and ignored copper, tin, lead, and iron, made their weapons and tools of hard wood and stone. Thomas Ewbank,[219] of New York, catalogues as breast-plates two laminæ of copper and one of bronze, the latter being notably the lighter. Out of sundry ‘bronzes’ from Peru he found four of pure copper. Chile had abundant mines of copper, and her metal is held to be the toughest: a bar three-eighths of an inch thick will bend backwards and forwards forty-eight times before breaking. Her chief centres are Copiapo (i.e. ‘turquoise’), Huasco, Coquimbo, Aconcágua and Caléo. The Couche range at Guatacondo, in sight of the desert of Atacama, which gave a name to Atacamite (submuriate of copper), is said to supply from the same vein gold, silver, copper, and coquimbite or white copperas called Pampua (packfong?).[220] Gillis (Plate viii. 12, 3) described, amongst the antiquities found near the great Ynkarial High-road, a cast copper axe, weighing about three and a quarter pounds: he doubts, however, that the ancient Chilians worked in that metal. The wild Araucanians called gold ‘copper’ (Bollaert, p. 184). According to Molina, the Puelche tribe extracted from the mines of Payen a copper containing half its weight (?) in gold; and the same natural alloy was found in the Curico mines.
COPPER.
Returning to the Old World, we see copper tools denoted in Egyptian hieroglyphs by a reddish-brown tint;[221] iron and steel, as in Assyria, being coloured, not grey, but water-blue.[222] With these yellow tools the old workmen are seen cutting stone blocks and fashioning colossal statues. Dr. John Forbes, of Edinburgh,[223] had a large chisel of pure copper, showing marks of use, found with a wooden mallet in an Egyptian tomb. A flat piece of copper, apparently a knife-blade, was turned up when boring thirteen feet below the surface where stands the statue of Ramses II. (b.c. 1400).[224] The Abbé Barthélemy proved, to the satisfaction of P. J. Rossignol, that the arms of the Greeks were first of copper; that iron was introduced about the date of the Trojan war (circ. b.c. 1200),[225] and that after this time ‘Athor-Venus’ was no more in use. Ulysses (‘Iliad,’ i. 4, 279) offers Achilles all the gold and copper he can collect, and Achilles will carry off all the gold, the red copper (χαλκὸν ἐρυθρόν), women, and iron or steel (σίδηρον), when Peleides returns that noble answer:
