It will be observed that Scylax says nothing in this passage of any traffic for gold. We can scarcely suppose, however, that the Phoenicians, if they penetrated so far south as this, could remain ignorant of the fact that West Africa was a gold-producing country, much less that, being aware of the fact, they would fail to utilise it. Probably they were the first to establish that “dumb commerce” which was afterwards carried on with so much advantage to themselves by the Carthaginians, and whereof Herodotus gives so graphic an account. “There is a country,” he says,[9108] “in Libya, and a nation, beyond the Pillars of Hercules, which the Carthaginians are wont to visit, where they no sooner arrive than forthwith they unlade their wares, and having disposed them after an orderly fashion along the beach, there leave them, and returning aboard their ships, raise a great smoke. The natives, when they see the sample, come down to the shore, and laying out to view so much gold as they think the wares are worth, withdraw to a distance. The Carthaginians upon this come ashore again and look. If they think the gold to be enough, they take it and go their way; but if it does not seem to them sufficient, they go aboard ship once more, and wait patiently. Then the others approach and add to their gold, till the Carthaginians are satisfied. Neither party deals unfairly by the other: for they themselves never touch the gold till it comes up to the worth of their goods, nor do the natives ever carry off the goods until the gold has been taken away.” The nature of the Phoenician trade with the Canaries, or Fortunate Islands, is not stated by any ancient author, and can only be conjectured. It would scarcely have been worth the Phoenicians’ while to convey timber to Syria from such a distance, or we might imagine the virgin forests of the islands attracting them.[9109] The large breed of dogs from which the Canaries derived their later name[9110] may perhaps have constituted an article of export even in Phoenician times, as we know they did later, when we hear of their being conveyed to King Juba;[9111] but there is an entire lack of evidence on the subject. Perhaps the Phoenicians frequented the islands less for the sake of commerce than for that of watering and refitting the ships engaged in the African trade, since the natives were less formidable than those who inhabited the mainland.[9112]
