An 18th-century German geometry primer by Adam Friedrich Ernst Jacobi, a preacher to the Saxe-Gotha regiment in Dutch service, published in 1765 by Dieterich for children and self-taught learners. Its plates are engraved diagrams of plane and solid figures, with lettered points, prisms, cones, spheres, and a tower, while the decorative cartouche and a baroque vignette of helmeted figures show the period's engraved ornament a designer could borrow for lettering and framing.
