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.
