La pratique du trait à preuves, de Mr Desargues ... pour la coupe des pierres en l'architecture
A 1643 French treatise on stone cutting by Girard Desargues, engraved by Abraham Bosse and printed in Paris by Pierre Des-Hayes, written for stonemasons and architects. Its pages are paired geometric plates of semicircular arches, lines, letters and angled rays, with labels such as sans taille, avec taille, Montée and Descente, showing how a stone's cut faces are projected.
