Strabo’s explanation, which seems from his words to have been the current one in his day, is extremely plausible, and it appears highly probable that from the first dawn of history the torrent-swept treasures of the Colchian land were well known to the dwellers in both Asia Minor and Europe. But this was not the only place in Asia Minor where gold was found. We shall have occasion again and again to refer to the Electrum of Sardis, obtained from the sand of the river Pactolus which flowed down from Mount Tmolus. Scholars are familiar with the account which Herodotus gives of these gold deposits, but probably the most convenient thing for our present purpose will be to quote Strabo’s enumeration of the kings and potentates of antiquity in Asia and Europe who were famous for their wealth, as he has added in each case the source from which their wealth was obtained. The current account as given by Callisthenes and others was, “that the wealth of Tantalus and the Pelopidae was derived from the mines of Phrygia and Sipylus, whilst the wealth of Cadmus came from the mines of Thrace and Mount Pangaeum, but that of Priam from the gold-mines at Astyra in the vicinity of Abydus, of which even now there are still scanty remnants. But the quantity of earth cast up is vast, and the diggings are proofs of the ancient mining operations. But the wealth of Midas came from the mines round Mount Bermion, whilst that of Gyges and Alyattes and Croesus came from the mines in Lydia. But in the district between Atarneus and Pergamus there is a deserted city, with places containing worked-out mines[103].” This passage gives a good picture of the gold-fields which in ancient days were worked round the shores of the Aegean. In the time of Strabo some of them were already worked out and gave but a scanty yield, for he says, “above the territory of the people of Abydus lies in the Troad Astyra, which now belongs to the people of Abydus, a ruined city, but aforetime it was independent, possessing gold-mines, now affording but a scanty yield, as they are exhausted, just like the mines on Mount Tmolus in the neighbourhood of the Pactolus.” The latter district was still productive in the days of Herodotus, who declared that the land of Lydia had few marvels to chronicle except the gold-dust that is borne down from Tmolus[104]. Strabo too, elsewhere[105], when describing the river system of this part of Asia Minor says, “the Pactolus flows from Tmolus, carrying down that ancient gold-dust from which they say that the famous wealth of Croesus and of his ancestors became renowned. But now the gold-dust has failed, as has been stated.”
