There can be no doubt that the idea of such a coinage was derived from that of St. Louis of France; and, just as in France, the issue seems to have been premature. Probably neither in the one country nor the other did there exist a sufficient store of the precious metal itself, nor sufficient activity of trade to attract such a store, or indeed to make a gold coinage at all a matter of mercantile advantage. It is only a developed and active or considerable trade that demands so enhanced a medium of exchange. Accordingly, just as in France, there is a noticeable gap between the first actual minting of gold by the predecessors of St. Louis, and the minting of it in such quantities as to make a factor in commercial and monetary history, in the days of Philip le Bel (1295); so, in England, the first issue of Henry III. was followed by an interval of nearly ninety years, during which no coinage of gold by our kings took place. The real introducer of this metal into English currency and commerce was Edward III., and the first practical issue of it is to be dated in 1344, rather than 1257. It will be seen at a glance what this statement implies. The issue of Henry III. in 1257 had been premature--an act of kingly rivalry and show, rather than of commercial necessity. But the succeeding century saw a rapid development in the commerce of Northern Europe, and a gold coinage had gradually become both a possibility and a necessity. One after the other--in the order of time just detailed--the various commercial states with which England had intercourse had adopted it and profited by it. That England should follow in the movement scarcely more than sixteen years later than Germany, and a year or two before Flanders, is some evidence of the organisation of her trade, as well as of the intimacy of inter-commercial relationships. So purely a matter of trade and natural growth was this vast movement of the adoption of a gold coinage--a revolution indeed as it proved, though yet unwritten, more momentous in its influence on European civilisation than either the Renaissance or the Reformation. [Sidenote: CHARACTERISTICS OF THE FIRST PERIOD] Approximately, therefore, the fourteenth century may be taken as the starting-point for a history of European bimetallism. The first period of that history embraces all the movements of the previous metals, from such starting-point up to the discovery of America in 1492--a matter of two centuries, roughly speaking.
