Die Grubenbaukunst
Die Grubenbaukunst is a German mining engineering treatise by Franz Ludwig von Cancrin, published in 1774 by the Andreäische Buchhandlung for mine builders and engineers. Its numbered copperplate plates show shaft linings, timber supports, and underground excavation details drawn in fine parallel hatching, which a designer might take as a model for dense engraved texture and architectural cross-sections.
