of that age is obvious, when we reflect on their habits and manners;--that
the precious metals would be a powerful attraction, and would be regarded
as cheaply acquired by the most hazardous enterprizes, is equally obvious.
If Sir Walter Raleigh, sound as he was for his era in the science of
political economy, was so far ignorant of the real wealth of nations, as to
be disappointed when he did not find El Dorado in America, though that
country contained much more certain and abundant sources of wealth,--can we
be surprized if the Greeks, at the time of the Argonautic expedition, could
be stimulated to such an enterprize, only by the hope of obtaining the
precious metals? It may, indeed, be contended that plunder was their
object; but it does not seem likely that they would have ventured to such a
distance from Greece, or on a navigation which they knew to be difficult
and dangerous, as well as long, for the sake of plunder, when there were
means and opportunities for it so much nearer home. We must equally reject
the opinion of Suidas, that the Golden Fleece was a parchment book, made of
sheep-skin, which contained the whole secret of transmuting all metals into
gold; and the opinion of Varro, that the Argonauts went to obtain skins and
other rich furs, which Colchis furnished in abundance. And the remarks
which we have made, also apply against the opinion of Eustathius, that the
voyage of the Argonauts was at once a commercial and maritime expedition,
to open the commerce of the Euxine Sea, and to establish forts on its
shore.

Having rendered it probable, from general considerations, that the object
was the obtaining of the precious metals, we shall next proceed to
strengthen this opinion, by showing that they were the produce of the
country near the Black Sea. The gold mines to the south of Trebizond, which
are still worked with sufficient profit, were a subject of national dispute
between Justinian and Chozroes; and, as Gibbon remarks, "it is not
unreasonable to believe that a vein of precious metal may be equally
