Auszug aus den Anfangsgründen und dem Lehrbegriffe der mathematischen Wissenschaften
An 1781 German mathematics textbook by Wenceslaus Johann Gustav Karsten, printed and published by Anton Ferdinand Röse, covering geometry, optics, and time measurement for students of the mathematical sciences. Its plates are dense engraved geometric diagrams of circles, triangles, and ray lines, with lettered points and numbered figures. A designer could draw on their precise linework, radiating construction lines, and labelled schematic layouts for technical or diagrammatic graphics.
