Traité des pratiques geometrales et perspectives : enseignées dans l'Academie royale de la peinture et sculpture
Abraham Bosse's 1665 Paris treatise on geometrical and perspective practice, engraved and published by the author for students of the Académie royale de peinture et de sculpture. The plates are etched line diagrams: cubes, prisms and wall planes set on ground grids, with dotted construction lines, cast shadows, lettered vertices and figure numbers, plus scale bars in feet; useful for hatching textures, technical line work and geometric abstraction.
