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 ...
