Atlas of 51 star maps, with the addition of the biblical constellation figures engraved by L. Kilian after M. Kager, and later states of Schecksius' charts. Cf. Warner, D.K. The sky explored, p. 229-230. Engraved t.p. Includes Jakob Bartsch's "Tabulae constellationum synopticae" and "Tabula canonica," p. 126-134. Errata: last page. Contains celestial cartography in the form of mainly regional constellation maps showing the northern and southern hemispheres, from the external perspective, and using both the equatorial and ecliptic coordinate systems. Plates are in two sets. Set A, Plates 1 - 54, feature stars-only constellation maps for regions centered around one or a few constellations--note the Adler's copy features different maps than those usually described (ours are not counterproofs). Tabula I and Tabula II in set A show equatorial hemispherical maps centered on the vernal and autumnal equinoxes respetively, with two small polar projections. Set B, Plates 1 - 54, show individual and regional maps featuring large-scale depictions of Schiller's new "Christianized" constellation creations. Set B, Tabula I and II show equatorial hemispherical maps of Schiller's new "Christianized" constellations centered on the vernal and autumnal equinoxes respectively, with two small polar projections.
