Terra machinis mota : dissertationes geometricae, mechanicae, physicae, hydrostaticae : in quibus machinarum coniurgatarum vires inter se comparantur : multiplici noua methodo terrae magnitudo & grauitas inuestigatur : Archimedes terrae motionem spondens ab arrogantiae suspicione vindicatur
A 1658 Latin mechanics treatise by the Jesuit mathematician Paolo Casati, printed in Rome, aimed at scholars and natural philosophers defending Archimedes' idea of moving the earth with machines. Its pictures are plain geometric diagrams: a circle with a centre, radii, and tangent lines drawn in fine black strokes on the printed page, with letters labelling points. A designer could take their clean, schematic line work and the simple circle-and-tangent compositions as a template for minimal technical diagrams.
