They traded with Tyre in the "persons of men" and in "vessels of brass" or copper.[987] Copper is found abundantly in the mountain ranges of these parts, and Xenophon remarks on the prevalence of metal vessels in the portion of the region which he passed through--the country of the Carduchians.[988] The traffic in slaves was one in which the Phoenicians engaged from very early times.
They were not above kidnapping men, women, and children in one country and selling them into another;[989] besides which they seem to have frequented regularly the principal slave marts of the time.

They bought such Jews as were taken captive and sold into slavery by the neighbouring nations,[990] and they looked to the Moschi and Tibareni for a constant supply of the commodity from the Black Sea region.[991] The Caucasian tribes have always been in the habit of furnishing slave-girls to the harems of the East, and the Thracians, who were not confined to Europe, but occupied a great part of Asia Minor, regularly trafficked in their children.[992] Such was the extent of the Phoenician land trade, as indicated by the prophet Ezekiel, and such were, so far as is at present known, the commodities interchanged in the course of it.

It is quite possible--nay, probable--that the trade extended much further, and certain that it must have included many other articles of commerce besides those which we have mentioned.

The sources of our information on the subject are so few and scanty, and the notices from which we derive our knowledge for the most part so casual, that we may be sure what is preserved is but a most imperfect record of what was--fragments of wreck recovered from the sea of oblivion.

It may have been a Phoenician caravan route which Herodotus describes as traversed on one occasion by the Nasamonians,[993] which began in North Africa and terminated with the Niger and the city of Timbuctoo; and another, at which he hints as lying between the coast of the Lotus-eaters and Fezzan.[994] Phoenician traders may have accompanied and stimulated the slave hunts of the Garamantians,[995] as Arab traders do those of the Central African nations at the present day.
Again, it is quite possible that the Phoenicians of Memphis designed and organised the caravans which, proceeding from Egyptian Thebes, traversed Africa from east to west along the line of the "Salt Hills," by way of Ammon, Augila, Fezzan, and the Tuarik country to Mount Atlas.[996] We can scarcely imagine the Egyptians showing so much enterprise.
