Agricola, Georg. V 66 9 A27g
Georgius Agricola de re metallica; tr. from the first Latin edition
of 1556, with biographical introduction, annotations and appendices
upon the development of mining methods, metallurgical processes,
geology, mineralogy & mining law from the earliest times to the 16th
century by H. C. Hoover and L. H. Hoover. 1912. Mining Magazine.
"Bibliographical notes," p.599-606.
"De re metallica" is the most important of the writings of Agricola (whose real
name was Georg Bauer). It was the first extensive systematic treatise on mining and
metallurgical processes.
"During 180 years it was not superseded as the text-book and guide to miners and
metallurgists. ..That it passed through some ten editions in three languages at a period
when the printing of such a volume was no ordinary undertaking is in itself sufficient
evidence of the importance in which it was held, and is a record that no other volume
upon the same subjects has equalled since." Translator's preface.
