consequence of their failing to recognize the great gulf which is fixed between the habits and ideas of a primitive community, slowly evolving principles which are now part and parcel of the common heritage of civilization, and an era like our own, when all progress is effected by the development and application of scientific principles long since discovered.
Electrum was thus coined on the same standard as silver, one talent, one mina and one stater of electrum being consequently equal to ten talents, ten minae, or ten staters of silver. The weight of the electrum stater in each district would depend therefore on the standard which happened to be in use there for silver bullion, or silver in the shape of bars or oblong bricks, the practice of the new invention of stamping or sealing metal for circulation being in the first place only applied to the more precious of the two metals, electrum representing in a small compass a weight of uncoined silver ten times as bulky and ten times as difficult of transport.
The invention was soon extended to pure gold and silver, and there is good reason to believe that by the time of Croesus (568-554 B.C.) both these metals were used for purposes of coinage in Lydia.
The Greeks begin to coin money.
The clever Greeks of Asia Minor, who formed the portal through which so many of the arts of the East reached the Western lands, were not slow to adopt, and by reason of their superior artistic taste to improve, the great Lydian invention. To the Ionic cities such as Phocaea and Miletus we must probably ascribe the credit of substituting artistically engraved dies for the rude Lydian punch-marks, and at a somewhat later period of inscribing them with the name or rather the initial of the people or potentate by whom they were issued.
The official stamps by which the earliest electrum staters were distinguished from mere ingots consisted at first only of the impress of
