De re metallica - Agricola - comemoração


Faz este ano 450 anos sobre a publicação do tratado De re metallica da autoria de Georg Bauer (1494-1555), conhecido por Agricola. Este livro, profusamente ilustrado , trata de assuntos mineralógicos e problemas relativos à exploração mineira. O facto de Agricola ser oriundo da Saxónia e de ter vivido grande parte da sua vida nessa região, terá condicionado certamente os seus interesses. A Saxónia era uma região mineira rica o que a tornou um local privilegiado para o desenvolvimento da mineralogia como ciência.
