The Aderlasskalender for the year 1457, also known as the Laxierkalender, was issued in Mainz, printed in the type of the 36-line Bible, presumably in 1456. It survives in only one incomplete copy in the Bibliothèque nationale de France (ISTC No. ia00051700).
"Bleeding- and purgation-calendars, which gave details of the lucky and unlucky days on which to bleed or take medicine in a given year, were popular in the Middle Ages. They maintained their popularity with the coming of the printed book. According to Osler, 'forty-six of these bleeding-and purgation-calendars were printed before 1480; one hundred of them before 1501 have been collected. . . .' The Mainz Kalendar for 1457 is much more a purgation-than a bleeding-calendar" (Berry & Poole, Annals of Printing  13).
