A child finds a shiny rock in a creek, thousands of years ago, and the human race is introduced to gold for the first time.

Gold was first discovered as shining, yellow nuggets. "Gold is where you find it," so the saying goes, and gold was first discovered in its natural state, in streams all over the world. No doubt it was the first metal known to early hominids.

Gold became a part of every human culture. Its brilliance, natural beauty, and luster, and its great malleability and resistance to tarnish made it enjoyable to work and play with.

Because gold is dispersed widely throughout the geologic world, its discovery occurred to many different groups in many different locales. And nearly everyone who found it was impressed with it, and so was the developing culture in which they lived.

Gold was the first metal widely known to our species. When thinking about the historical progress of technology, we consider the development of iron and copper-working as the greatest contributions to our species' economic and cultural progress - but gold came first.

Gold is the easiest of the metals to work. It occurs in a virtually pure and workable state, whereas most other metals tend to be found in ore-bodies that pose some difficulty in smelting. Gold's early uses were no doubt ornamental, and its brilliance and permanence (it neither corrodes nor tarnishes) linked it to deities and royalty in early civilizations .

Gold has always been powerful stuff. The earliest history of human interaction with gold is long lost to us, but its association with the gods, with immortality, and with wealth itself are common to many cultures throughout the world.

Early civilizations equated gold with gods and rulers, and gold was sought in their name and dedicated to their glorification. Humans almost intuitively place a high value on gold, equating it with power, beauty, and the cultural elite. And since gold is widely distributed all over the globe, we find this same thinking about gold throughout ancient and modern civilizations everywhere.

Gold, beauty, and power have always gone together. Gold in ancient times was made into shrines and idols ("the Golden Calf"), plates, cups, vases and vessels of all kinds, and of course, jewelry for personal adornment.

The "Gold of Troy" treasure hoard, excavated in Turkey and dating to the era 2450 -2600 B.C., show the range of gold-work from delicate jewelry to a gold gravy boat weighing a full troy pound. This was a time when gold was highly valued, but had not yet become money itself. Rather, it was owned by the powerful and well-connected, or made into objects of worship, or used to decorate sacred locations.

Gold has always had value to humans, even before it was money. This is demonstrated by the extraordinary efforts made to obtain it. Prospecting for gold was a worldwide effort going back thousands of years, even before the first money in the form of gold coins appeared about 700 B.C.

In the quest for gold by the Phoenicians, Egyptians, Indians, Hittites, Chinese, and others, prisoners of war were sent to work the mines, as were slaves and criminals. And this happened during a time when gold had no value as 'money,' but was just considered a desirable commodity in and of itself.

The 'value' of gold was accepted all over the world. Today, as in ancient times, the intrinsic appeal of gold itself has that universal appeal to humans. But how did gold come to be a commodity, a measurable unit of value?
