What happened

In 1545 an Indigenous man, Diego Huallpa, is said to have found silver on the Cerro Rico, a red mountain 4,000 metres up in the Andes of today's Bolivia. Potosí grew into one of the largest cities in the world, with about 160,000 people by 1600, when its more than 600 mines yielded around 9 million pesos a year, more than all the rest of the world's silver mines. From about 1560 the ore was refined with mercury, and from the 1570s Viceroy Toledo's mita obliged Andean villages to send men in rotation to the mines, where many died. The Crown took a fifth. 'Vale un Potosí', worth a Potosí, still means something priceless in Spanish.

Say it

En español, algo que vale mucho 'vale un Potosí'.

In Spanish, something very valuable 'is worth a Potosí'.

Why it matters

Potosí's silver paid for Spain's wars, inflated prices across Europe and filled China's treasury; 'vale un Potosí' entered the language through Cervantes.
