Let us now take a general survey of the region over which we have travelled. In the far east we had both the literary evidence of the Rig Veda and the evidence of the traditions and legends handed down by the historians to show that well back in the second millennium B.C. the gold deposits of Thibet were known and worked. Silver is as yet unknown to the people of the Rig Veda. Again in the region of the Altai and Oural mountains, the tale of the “Arimaspian pursued by a griffin” pointed to great antiquity for gold-mining in this district; the barbarous Massagetae[150], who occupied the modern Mongolia and Sangaria, were rich in gold; and to the west the Scythians, who used neither silver nor copper, had abundant store of gold. These tribes stretched right across Russia until they touched on the west the Getae and the other tribes of the great Thracian stock. Gold must early have been known throughout all Thrace. Greek tradition and history unite in demonstrating the great antiquity of the first Phoenician gold-seeking in Thasos and on the mainland. The evidence in Greece itself puts it beyond doubt that gold was in use 1500 years B.C. The Balkan Peninsula was occupied on the north-west by Illyrian tribes, some of whom, like the Dardani, dwelt interspersed among the Thracian clans. The Illyrians inhabited all the northern end of the Adriatic, and originally much of the east side of all Italy, although under the pressure of the Umbrians and Kelts they had been almost completely crushed out of the Italian Peninsula, only maintaining themselves in the extreme southeast where the Messapians remained independent of both Italian and Greek alike. The Keltic tribes were their neighbours in Noricum, where they had succeeded the ancient Rhaetian stock, the survivors of which, like the Salassi, had managed to maintain themselves in the fastnesses of the Alps. We found strong evidence that these Rhaetians must long have known the art of working gold, for they had devised elaborate pieces of engineering work for the purpose of developing their gold fields; added to this was the fact that gold as an ornament seems to have been used by the inhabitants of the Swiss lake dwellings in the neolithic age. The Kelts must have been in contact with this people for a considerable time before they ever invaded Italy; again in Spain we found every token of great antiquity in the working of gold and silver. Again, before they invaded Italy, the Kelts must have been long in contact with the Iberians of what in later days was Aquitania, for the Keltic conquest of Northern Spain can hardly be placed later than in the fifth century B.C., and it is most probable that that conquest only took place after long and stubborn struggles. The Kelts too in Southern Gaul must have come in contact with the Ligyes (or Ligurians), whose territory at one time extended from the Iberus (Ebro) along the coast of the Mediterranean to the frontiers of Etruria.
