Very nice - is that Jan Jansson? 30 years later and with print on pasteboard rather than manuscript on parchment. (I should really have tagged #volvelles and #astrolabes originally.)

Four astrolabe latitude plates from Giovanni Paolo Gallucci’s Corporum Coelestium… (1603), unneeded but preserved for potential future use by being stuck into the blank opening after the book’s title page. My photograph 16/1/2025

Of all the (many) copies I’ve inspected, this one most closely respects the instructions to booksellers and binders for the DIY assembly of its dozens of #volvelles. It even preserves the unused latitude plates of the “multipurpose rotula” (a mini-astrolabe). @drkarrschmidt.bsky.social 13/25

my love for #volvelles cannot be understated

A page from "Der Nöthige Gefehrte" (VD17 39:156118Z) showing an illustration on how to calculate correctly in an astronomical way. Access a digital copy from the Forschungsbibliothek Gotha (Theol 8° 00686a (04)) here: https://dhb.thulb.uni-jena.de/receive/ufb_cbu_00040114

The Necessary Companion (in German "Der Nöthige Gefehrte") was a perpetual calendar published in 1675 Leipzig, Germany. The pamphlet provided detailed information on how to use this #almanac: including 3 #volvelles to calculate correctly. This was an #earlymodern learning tool to teach #astronomy.

Penn Libraries has what looks like a great exhibit of #movablebooks up through December 13 - wish I could get over there and see it! In the meantime this article will have to suffice. #popupbooks #volvelles
