Traité de la coupe des pierres, ou, Méthode facile et abregée, pour se perfectionner en cette science
A 1764 Paris treatise on stereotomy, the geometry of cutting stone, written by Jean Baptiste de La Rue and published by Charles-Antoine Jombert for French royal artillery and engineering officers and masons. Its pages are full-page copperplate engravings of stone blocks, vaults and cut joints drawn in shaded isometric projection with construction lines. A designer could draw on their crisp hatched planes and faceted solids for geometric diagrams, architectural line studies, or abstract faceted forms.
