Gold as Money

Gold, measured out, became money. Gold's beauty, scarcity, unique density (no other metal outside the platinum group is as heavy), and the ease by which it could be melted, formed, and measured made it a natural trading medium. Gold gave rise to the concept of money itself: portable, private, and permanent. Gold (and silver) in standardized coins came to replace barter arrangements, and made trade in the Classic period much easier.

Gold was money in ancient Greece. The Greeks mined for gold throughout the Mediterranean and Middle East regions by 550 B.C., and both Plato and Aristotle wrote about gold and had theories about its origins. Gold was associated with water (logical, since most of it was found in streams), and it was supposed that gold was a particularly dense combination of water and sunlight.

Their science may have been primitive, but the Greeks learned much about the practicalities of gold mining. By the time of the death of Alexander of Macedon (323 B.C.), the Greeks had mined gold from the Pillars of Hercules (Gibraltar) all the way eastward to Asia Minor and Egypt, and we find traces of their placer mines today. Some of the mines were owned by the state, some were worked privately with a royalty paid to the state. Also, nomads such as the Scythians and Cimmerians worked placer mines all over the region. The surviving Greek gold coinage and Scythian jewelry both show superb artistry.

The Roman Empire furthered the quest for gold. The Romans mined gold extensively throughout their empire, and advanced the science of gold-mining considerably. They diverted streams of water to mine hydraulically, and built sluices and the first 'long toms.' They mined underground, also, and introduced water-wheels and the 'roasting' of gold-bearing ores to separate the gold from rock. They were able to more efficiently exploit old mine-sites, and of course their chief laborers were prisoners of war, slaves, and convicts.

A monetary standard made the world economy possible. The concept of money, (i.e., gold and silver in standard weight and fineness coins) allowed the World's economies to expand and prosper. During the Classic period of Greek and Roman rule in the western world, gold and silver both flowed to India for spices, and to China for silk. At the height of the Empire (A.D. 98-160), Roman gold and silver coins reigned from Britain to North Africa and Egypt.
Money had been invented. Its name was gold.
