_{The Macrocosm:}

The heavens as well as the earth, have long fascinated people, and the Collections have a fine selection of books on astronomy. Among these are two incunabula.

Johannes Mueller (Regiomontanus). Calendarium.
Venice: Bernhard Maler (Pictor), Erhard Ratdolt, Peter Löslein, 1476.

This incunabulum contains astronomical tables and shows predicted times of solar and lunar eclipses, beginning in -- and extending to --. The German astronomer Johannes Müller (1436-1476), known as Regiomontanus from his birthplace, was a mathematician, the founder of an observatory, and a compiler of calendars. The printer of this book, Ratdolt, was one of the most skilled artisans in his profession. Although most incunabula do not have title pages but include the information about publication at the end (the colophon ), the Kalendarium is the first printed book to have an ornamental title page.
