1. - BLOODLETTING CALENDAR FOR 1462 [Vienna: Ulrich Han? late 1461]
- Curatorial Note:
- It was a fundamental belief of ancient and medieval medicine that there are good and bad days for bloodletting and taking purgatives, governed by the phases of the Moon. Gutenberg printed a bloodletting Calendar for the year 1457 using his DK type, uniquely preserved at the Bibliothèque Nationale de France. The present Calendar states that its New Moon and Full Moon times are calculated on the meridian of Vienna. These times are not printed, but added by hand, as Arabic numerals, in red ink, and they are of remarkable accuracy. It has been supposed that they were calculated by the famous astronomer-mathematician Regiomontanus, who at this time was in Vienna. The small images representing the opposite phases of the Moon are woodcuts. Thus printmaking, typography, and calligraphy are combined to create the calendar.
