The mountain of Potosí in Bolivia has yielded more silver than any other mountain or region of the world. In the 16th and 17th centuries this wealth flowed through Spain into Europe, while the grueling work of extracting the silver was left to the indigenous population, who were enslaved by the Spanish and died by the thousands. Today, Potosí maintains this unique culture: some 1800 miners work in or around the mountain, scraping for traces of silver and tin and worshiping a devil?represented as a sexually potent Spaniard?in hopes that he won't take their lives. Photojournalist Stephen Ferry documents this stunning realm in 85 large color images.
