Systema compendiosum totius mathematices, hoc est, geometriæ, opticæ, astronomiæ et geographiæ,
A 1621 Hanau mathematics textbook by Bartholomaeus Keckermann, compiling geometry, optics, astronomy and geography for university students and teachers of the period. Its pictures are small line diagrams of circles, intersecting arcs, tangent lines and labelled Greek-letter points, set beside Latin text, offering a designer clean geometric motifs and compass-drawn construction patterns.
