L'art de jetter les bombes
A 1683 Paris treatise on artillery and ballistics by Blondel, Broebes, Langlois and Le Cointe, written for gunners and engineers who needed to calculate bomb trajectories. Its pictures are geometric diagrams of parabolic arcs, lettered construction lines, circles and right triangles drawn in fine black ink on cream paper, useful to a designer for stark line-based trajectory and motion graphics.
