Manuscript, 17th cent., black and red pen and ink, 165 lvs., num. drawings/ diagrams/ tables, 6 fold. engr. maps/ plates, without binding.

- Contents loose(ning); first and final lvs. sl. waterst./ frayed; plates w. sm. tears on folds; some lvs. empty.

= Contains 7 chapters of an (autograph?) work on cosmography, with astronomical propositions and mathematical computations, specifically regarding the position of the stars/ constellations and the calculation of time (paragraphs on i.a. the caelum stellatum, sphoera, theorica planetarum and horologia). We could not trace the manuscript's contents to any published work. The text is accomp. by rare engr. plates from printed works, i.a. the fold. world map by GIOVANNI MAGINI ("Orbis terrae compendiosa descriptio", the reduced Mercator-Porro map, orig. publ. Cologne, 1597. Shirley 202) and 4 fold. maps/ plates by JACOB VAN DER HEYDEN: two planispheres (from Habrecht and Sturm's Planiglobium coeleste, et terrestre, orig. publ. Strasb., 1628), a sundial ("Praeterit hicce dies, nescitur origo secundi, an labor, an requies: sic transit fabula mundi", possibly after E. Welper, ±1630) and "Cubus Sciothericus" (±1620). The drawings show i.a. a volcano, an astronomer, the phases of the moon and sundials. The second part of the manuscript contains (the calculations for) a calendar of saints.
