The Money Mountain (II)

To work the mines, the Spaniards at first relied on paying wages to the inhabitants of nearby villages. But conditions were so harsh that from the late sixteenth century a system of forced labour (la mita) had to be introduced, whereby men aged between 18 and 50 from the sixteen highland provinces were conscripted for seventeen weeks a year.1 1 Mortality among the miners was horrendous, not least because of constant exposure to the mercury fumes generated by the patio process of refinement, whereby ground-up silver ore was trampled into an amalgam with mercury, washed and then heated to burn off the mercury. The air
down the mineshafts was (and remains) noxious and miners had to descend seven-hundred-foot shafts on the most primitive of steps, clambering back up after long hours of digging with sacks of ore tied to their backs. Rock falls killed and maimed hundreds. The new silver-rush city of Potosi was, declared Domingo de Santo Tomâs, 'a mouth of hell, into which a great mass of people enter every year and are sacrificed by the greed of the Spaniards to their "god".' Rodrigo de Loaisa called the mines 'infernal pits', noting that 'if twenty healthy Indians enter on Monday, half may emerge crippled on Saturday'. In the words of the Augustinian
monk Fray Antonio de la Calancha, writing in 1638: 'Every peso coin minted in Potosi has cost the life of ten Indians who have died in the depths of the mines.' As the indigenous workforce was depleted, thousands of African slaves were imported to take their places as 'human mules'. Even today there is still something hellish about the stifling shafts and tunnels of the Cerro Rico.

The Cerro Rico at Potosi: the Spanish Empire's mountain of money

A place of death for those compelled to work there, Potosi was where Spain struck it rich. Between 1556 and 1783, the 'rich hill' yielded 45,000 tons of pure silver to be transformed into bars and coins in the Casa de Moneda (mint), and shipped to Seville. Despite its thin air and harsh climate, Potosi rapidly became one of the principal cities of the Spanish Empire, with a population at its zenith of between 160,000 and 200,000 people, larger than most European cities at that time. Valer un potosi, 'to be worth a potosi', is still a Spanish expression meaning to be worth a fortune. Pizarro's conquest, it seemed, had made the Spanish crown rich beyond the dreams of avarice.
Money, it is conventional to argue, is a medium of exchange, which has the advantage of eliminating inefficiencies of barter; a unit of account, which facilitates valuation and calculation; and a store of value, which allows economic transactions to be conducted over long periods as well as geographical distances. To
perform all these functions optimally, money has to be available, affordable, durable, fungible, portable and reliable. Because they fulfil most of these criteria, metals such as gold, silver and bronze were for millennia regarded as the ideal monetary raw material.

The earliest known coins date back as long ago as 600 BC and were found by archaeologists in the Temple of Artemis at Ephesus (near Izmir in modern-day Turkey). These ovular Lydian coins, which were made of the gold-silver alloy known as electrum and bore the image of a lion's head, were the forerunners of the Athenian tetradrachm, a standardized silver coin with the head of the goddess Athena on one side and an owl (associated with her for its supposed wisdom) on the obverse. By Roman times, coins were produced in three different metals: the aureus (gold), the denarius (silver) and the sestertius (bronze), ranked in that order according to the relative scarcity of the metals in question, but all bearing the head of the reigning emperor on one side, and the legendary figures of Romulus and Remus on the other. Coins were not unique to the ancient Mediterranean, but they clearly arose there first. It was not until 221 BC that a standardized bronze coin was introduced to China by the 'first Emperor', Qin Shihuangdi. In each case, coins made of precious metal were
associated with powerful sovereigns who monopolized the minting of money partly to exploit it as a source of revenue.
