Institutions astronomiques
Institutions astronomiques is an 1746 French astronomy textbook by Pierre-Charles Le Monnier, published in Paris by Hippolyte-Louis and Jacques Guerin for students of the subject. Its pictures are engraved geometric plates of circles, arcs, and orbital diagrams with lettered points and fine hatching, offering a designer clean, precise linework for diagrammatic patterns, celestial motifs, and technical schematics.
