There was a saying of Phalereus in reference to the eagerness of the miners of Laurium in Attica, that they dug as continuously and earnestly as if they expected to drag up Pluto himself. This saying Posidonius quotes anent the energy and vigour of those who worked the Spanish mines, for they cut deep and winding galleries, and by means of 'Egyptian pumps' combated the springs which burst into the workings ."

So rich were the silver mines of New Carthage (Cartagena) that in the time of Polybius (140 ) 40,000 men were employed in working them for the Roman State, and the daily out-put was reckoned at 25,000 drachms, or roughly speaking about 3,000 ounces Troy.

Diodorus Siculus gives an account of mines and mining in Spain, which, as it is clearly derived from the same passage of Posidonius as the account of Strabo, is worth quoting, especially as it gives probably in extenso what Strabo has summarized. For although it more particularly refers to the discovery of silver mines, yet it is very relevant to our subject, since silver invariably is later in point of discovery than gold; thus if we can fix at an early period an inferior limit for the knowledge of silver in Spain, we may with confidence fix the inferior limit for the knowledge of gold at a still earlier epoch. Diodorus has been describing the range of the Pyrenees, which like all the early geographers he represents as running north and south, and thus proceeds: "Since there are on them (the Pyrenees) many forests dense with trees, they say that in ancient times the whole mountain region was completely burned by some shepherds having cast away a firebrand. Then since the fire kept burning on for many days continuously, the surface of the earth was burned and the mountains from the circumstance were called Pyrenaean ([Greek: Pyrênaia], scorched), and the surface of the burnt region flowed with much silver, and since the natural ore had been smelted, there ensued many lava-like streams of pure silver. But inasmuch as the natives did not understand the use of it, the Phoenicians trading with them, and having learned about the occurrence, bought the silver for some small
