Chapter X—Mining
Surface gathering of metals, anterior to mining—Earliest known mining operations—Earliest Phoenician mining in Phoenicia Proper—Mines of Cyprus—Phoenician mining in Thasos and Thrace—in Sardinia—in Spain—Extent of the metallic treasures there—Phoenician methods not unlike those of the present day—Use of shafts, adits, and galleries—Roof of mines propped or arched—Ores crushed, pounded, and washed—Use of quicksilver unknown—Mines worked by slave labour.
The most precious and useful of the metals lie, in many places, so near the earth’s surface that, in the earliest times, mining is unneeded and therefore unpractised. We are told that in Spain silver was first discovered in consequence of a great fire, which consumed all the forests wherewith the mountains were clothed, and lasted many days; at the end of which time the surface of the soil was found to be intersected by streams of silver from the melting of the superficial silver ore through the intense heat of the conflagration. The natives did not know what to do with the metal, so they bartered it away to the Phoenician traders, who already frequented their country, in return for some wares of very moderate value.101 Whether this tale be true or no, it is certain that even at the present day, in what are called “new countries,” valuable metals often show themselves on the surface of the soil, either in the form of metalliferous earths, or of rocks which shine with spangles of a metallic character, or occasionally, though rarely, of actual masses of pure ore, sometimes encrusted with an oxide, sometimes bare, bright, and unmistakable. In modern times, whenever there is a rush into any gold region—whether California, or Australia, or South Africa—the early yield is from the surface. The first comers scratch the ground with a knife or with a pick-axe, and are rewarded by discovering “nuggets” of greater or less dimensions; the next flight of gold-finders search the beds of the streams; and it is not until the supply from these two sources begins to fail that mining, in the proper sense of the term, is attempted.
The earliest mining operations, whereof we have any record, are those conducted by the Egyptian kings of the fourth, fifth and twelfth dynasties, in the Sinaitic region. At two places in the mountains between Suez and Mount Sinai, now known as the Wady Magharah and Sarabit-el-Khadim, copper was extracted from the bosom of the earth by means of shafts laboriously excavated in the rocks, under the auspices of these early Pharaohs.102 Hence at the time of the Exodus the process of mining was familiar to the Hebrews, who could thus fully appreciate the promise,103 that they were about to be given “a good land”—“a land whose stones were iron, and out of whose hills they might dig brass.” The Phoenicians, probably, derived their first knowledge of mining from their communications with the Egyptians, and no doubt first practised the art within the limits of their own territory—in Lebanon, Casius, and Bargylus. The mineral stores of these regions were, however, but scanty, and included none of the more important metals, excepting iron. The Phoenicians were thus very early in their history driven afield for the supply of their needs, and among the principal causes of their first voyages of discovery must be placed the desire of finding and occupying regions which contained the metallic treasures wherein their own proper country was deficient.
It is probable that they first commenced mining operations on a large scale in Cyprus. Here, according to Pliny,104 copper was first discovered; and though this may be a fable, yet here certainly it was found in great abundance at a very early time, and was worked to such an extent, that the Greeks knew copper, as distinct from bronze, by no other name than that of χαλκος Κύπριος, whence the Roman Æs Cyprium, and our own name for the metal. The principal mines were in the southern mountain range, near Tamasus,105 but there were others also at Amathus, Soli, and Curium.106 Some of the old workings have been noticed by modern travellers, particularly near Soli and Tamasus,107 but they have neither been described anciently nor examined scientifically in modern times. The ore from which the metal was extracted is called chalcitis by Pliny,108 and may have been the “chalcocite” of our present metallurgical science, which is a sulphide containing very nearly eighty per cent. of copper. The brief account which Strabo gives of the mines of Tamasus shows that the ore was smelted in furnaces which were heated by wood fires. We gather also from Strabo that Tamasus had silver mines.
That the Phoenicians conducted mining operations in Thasos we know from Herodotus,109 and from other writers of repute1010 we learn that they extended these operations to the mainland opposite. Herodotus had himself visited Thasos, and tells us that the mines were on the eastern coast of the island, between two places which he calls respectively Ænyra and Coenyra. The metal sought was gold, and in their quest of it the Phoenicians had, he says, turned an entire mountain topsy-turvy. Here again no modern researches seem to have been made, and nothing more is known than that at present the natives obtain no gold from their soil, do not seek for it, and are even ignorant that their island was ever a gold-producing region.1011 The case is almost the same on the opposite coast, where in ancient times very rich mines both of gold and silver abounded,1012 which the Phoenicians are said to have worked, but where at the present day mining enterprise is almost at a standstill, and only a very small quantity of silver is produced.1013
Sardinia can scarcely have been occupied by the Phoenicians for anything but its metals. The southern and south-western parts of the island, where they made their settlements, were rich in copper and lead; and the position of the cities seems to indicate the intention to appropriate these metals. In the vicinity of the lead mines are enormous heaps of scoriæ, mounting up apparently to a very remote era.1014 The scoriæ are not so numerous in the vicinity of the copper mines, but “pigs” of copper have been found in the island, unlike any of the Roman period, which are perhaps Phoenician, and furnish specimens of the castings into which the metal was run, after it had been fused and to some extent refined. The weight of the pigs is from twenty-eight to thirty-seven kilogrammes.1015 Pigs of lead have also been found, but they are less frequent.
But all the other mining operations of the Phoenicians were insignificant compared with those of which the theatre was Spain. Spain was the Peru of the ancient world, and surpassed its modern rival, in that it produced not only gold and silver, but also copper, iron, tin, and lead. Of these metals gold was the least abundant. It was found, however, as gold dust in the bed of the Tagus;1016 and there were mines of it in Gallicia,1017 in the Asturias, and elsewhere. There was always some silver mixed with it, but in one of the Gallician mines the proportion was less than three per cent. Elsewhere СКАЧАТЬ
