Astrolabium, Das ist: Gründliche Beschreibung - Ritter, Franz [Franciscum] - 1659. 
Christoff Gerhard for Paul Fürst, Nuremberg, Germany - No date but about 1659-1660. Text in German. Two parts in one: 1) Astrolabium, Das ist: Gründliche Beschreibung und Unterricht, wie solches herrliche und hochnützliche Astronomische Instrument, auff allerley Polus Höh, so wol auch nach eines jeden selbst gefälligen Gröss auffgerissen, und verfertigt werden soll. Darnach wei dasselbe vielfältig zu gebrauchen: Mit Kupferstücken verfertiget; 2) De usu Astrolabii, Posterior Pars. Full vellum binding, possibly contemporary but likely somewhat later. Vellum age-faded and with occasional pinpoint splotches. Remnants of label to spine, with handwritten title and author. Roman numeral IV appears at spine tail. Moderate chipping at spine head and tail. Front corners moderately bumped and abraded. Hinges cracked and binding threatening to detach from text block. 7 x 5.75 inches (18 x 14.5 cm.) On rag content, laid paper. With 136 and 64 numbered pages, additional engraved title-page by P. Troschel, woodcut initials and tailpieces, and 21 engraved plates in first part, as called for. All 21 plates remarkably clean, apart from light age-toning. Note that this copy lacks the 15 large folding engraved plates that appeared in the second part of some issues. The signatures comprising the text block appear soundly bound together, except that the front title pages are loosening and the signature comprising pp. 27-30 is loosening. A few names and dates in neat ink hand to front pastedown and opposite FEP. Age toning at the very edge of all pages. Age darkening to the preliminaries, especially the last several pages. Of uncertain provenance but illustrated title page and final text page with inscription, "Coll. Sue. Jesse Bamberg" [?]. Else a rather clean copy. Downgraded to Good Plus chiefly on account of the state of the binding. Deemed worthy of restoration and conservation. With thanks to W. P. Watson Antiquarian Books for the following: "Illustrated treatise on the construction and use of astrolabes. The two parts were first published separately in Nuremberg in 1613. There appear to be numerous variant editions. This one conforms to that of Yale and Brown, which they date to the 1640s, but other authorities give 1659 and 1660 as the dates of publication. The plates in the first part are printed from the same coppers used in the 1613 edition. The second part of the 1613 edition was unillustrated. Franz Ritter was an astronomer and innovative cartographer, famous for his 'sundial' world map. Ritter specialized in the design and manufacture of astrolabes, sundials, and other astronomical, horological and cartographical instruments." Size: 12mo - over 6¾" - 7¾" tall [Attributes: Hard Cover]
