In the second part of our alchemical journey, we meet what ancient philosophers called the “noble” metals: mercury, silver, and gold. How did a nineteenth-century set designer harness one of the most captivating—and toxic—materials in the world and wind up as one of the fathers of photography? When does a coin go from a piece of stamped metal to an act of faith? And how did gold in Ghana go from dust in the water to a touchstone of language, story, and the strength of an empire?
