The renowned miner Bartolom de Medina is the figure who brings us together to read this book and learn about his major contributions to metallurgy. In a historical context filled with geographical discoveries followed by conquests and colonizations, mining became a decisive economic factor in what was then New Spain. Born in Seville, Medina also stood out as a merchant within the mining industry for his significant contributions; among them, the first practical application of the amalgamation method--a process he developed himself to extract silver--in Pachuca, Hidalgo, at the end of 1544. This volume undoubtedly preserves memorable documents detailing the life and work of this tireless metallurgist, whose alchemical breakthrough bore fruit not only in Mexico, but also across South America and Europe.
