Tin, which has not been found in a pure state in the remains of the Assyrians, but which enters regularly as an element into their bronze, where it forms from one-tenth to one-seventh of the mass, was also, probably, an importation. Tin is a comparatively rare metal. Abundant enough in certain places, it is not diffused at all widely over the earth’s surface. Neither Assyria itself nor any of the neighboring countries are known to have ever produced this mineral. Phoenicia certainly imported it, directly or indirectly, from Cornwall and the Scilly Isles, which therefore became first known in ancient geography as the Cassiterides or “Tin Islands.” It is a reasonable supposition that the tin wherewith the Assyrians hardened their bronze was obtained by their merchants from the Phoenicians in exchange for textile fabrics and (it may be) other commodities. If so, we may believe that in many instances the produce of our own tin mines which left our shores more than twenty-five centuries ago, has, after twice travelling a distance of many thousand miles, returned to seek a final rest in its native country. Ivory was used by the Assyrians extensively in their furniture, and was probably supplied by them to the Phoenicians and the Greeks. It was no doubt sometimes brought to them by subject nations as tribute; but this source of supply is not sufficient to account, at once, for the consumption in Assyria itself, and for the exports from Assyria to foreign countries. A regular trade for ivory seems to have been carried on from very early times between India and Dedan (Bahrein,?) in the Persian Gulf. The travelling companies of the Dedanim, who conveyed this precious merchandise from their own country to Phoenicia, passed probably along the course of the Euphrates, and left a portion of their wares in the marts upon that stream, which may have been thence conveyed to the great Assyrian cities. Or the same people may have traded directly with Assyria by the route of the Tigris. Again, it is quite conceivable--indeed, it is probable--that there was a land traffic between Assyria and Western India by the way of Cabal, Herat, the Caspian Gates, and Media. Of this route we have a trace in the land animals engraved upon the well-known Black Obelisk, where the combination of the small-eared or Indian elephant and the rhinoceros with the two-humped Bactrian camel, sufficiently marks the line by which the productions of India, occasionally at, any rate, reached Assyria. The animals themselves were, we may be sure, very rarely transported. Indeed, it is not till the very close of the Persian empire that we find elephants possessed--and even then in scanty numbers--by the western Asiatic monarchs. But the more portable products of the Indus region, elephants’ tusks, gold, and perhaps shawls and muslins, are likely to have passed to the west by this route with far greater frequency.
