But results far more important than merely the determination of the value of Homeric commodities may be obtained as regards the weight-standards of Europe and their congeners in Asia. For by taking as our primitive unit the cow or ox, we may be able to give a much more simple account of the genesis of those standards than that which hitherto has been the received one. We have found the Homeric ox and talent identical with the didrachm or stater of the Euboic-Attic standard. All the silver coinage of Greece proper was struck either on this standard or the Aeginetic, and what is still more important for us it was on the Euboic-Attic standard alone that gold was estimated in every part of Greece. Practically the stater of this system was of the same weight as the famous Persian daric which in historical times formed the chief coin-unit of all Asia from India to the Aegean shores. CHAPTER II.

Let us here propound the doctrine which seeks to obtain an explanation of the origin for weight-standards more in accordance with the facts of history and the process of development as exemplified both in ancient and modern times. In early communities[17] all commodities alike are exchanged by bartering the one against the other. The man who possesses sheep exchanges them for oxen with the man who possesses oxen, the owner of corn exchanges his commodity for some implement or ornament of metal with the owner of the latter. The metals are only regarded as merchandise, not yet being in any degree set apart to serve as a medium of exchange in the terms of which all other commodities are valued. This is the practice which prevails in so civilized a country as China down to our own days. The only coinage which the Chinese possess is copper _cash_. According to M. le Comte Rochechouart (_Journal des Économistes_, Vol. XV. p. 103) both gold and silver are treated simply as merchandise, and there is not even a recognized stamp or government guarantee of the fineness of the metal. The traveller must carry these metals with him, as a sufficient quantity of strings of _cash_ would require a waggon for their conveyance. Yet in exchanging silver or gold he is sure to suffer loss both from the falsity of balances and of weights and the uncertain fineness of the metal.
