Machinæ coelestis pars prior[-posterior]
Machinæ coelestis is a 1673 astronomy treatise by Johannes Hevelius, with assistance from Andreas Stech, printed at Danzig by S. Reiniger for scholars and observers. Its pages show dense tabulated observations of planetary and cometary positions, with ruled columns of degrees, minutes and times, and a plainly set title block, offering a designer dense tabular rhythm and classical letterpress hierarchy.
