De re metallica

De re metallica (Latin for On the Nature of Metals (Minerals)) is a book cataloguing the state of the art of mining, refining, and smelting metals, published in 1556. The author was Georg Bauer, whose pen name was the Latinized Georgius Agricola. The book remained the authoritative text on mining for 180 years after its publication.

Agricola had spent nine years in the Bohemian town of Joachimsthal, now in the Czech Republic.
