Die Markscheidekunst, welche die Arithmetik Geometrie und ebene Trigonometrie enthält
A mining-surveying textbook by Franz Ludwig von Cancrin, published in 1775 by the Andreäische Buchhandlung, teaching arithmetic, geometry and plane trigonometry to surveyors and miners. The plates are numbered engraved geometric diagrams of circles, inscribed triangles, squares, parallelograms and dividing lines, labelled with letters at each point. A designer could draw on their crisp, schematic line work, precise lettering and clean geometric structure for diagrammatic or technical graphics.
