Traité de perspective pratique, pour dessiner d'après nature : mis à la portée de toutes les intelligences
A perspective treatise by J. P. Thénot, published in Liège in 1845 for students and amateur draughtsmen who wanted to draw from nature. The single plate shows four numbered figures of architectural subjects, a stair and doorway, a building corner, a shed with a figure, and a sloping roofed structure receding toward trees, drawn with fine hatching and orthogonal lines. A designer could take from it the clear use of converging lines and receding planes to build depth in a simple scene.
