De quadratura circuli mechanici, das ist, Ein neuer, kurtzer, hochnützlicher und leichter mechanischer Bericht von der Vierung oder Quadratur des Circkels ... erster und andrer Theil
A 1653 Nuremberg treatise on squaring the circle, written by Philipp Uffenbach and published by Paul Fürst, a print dealer, for mathematically minded readers and craftsmen interested in mechanical geometry. Its pages are numbered geometric diagrams of circles, triangles and lattices, set out as labelled figures with lettered points and occasional gear and wheel drawings, showing construction steps a designer could adapt as compass-and-ruler motifs, rosette patterns or diagrammatic layouts.
