girdle calendar
A small medieval folding calendar, so made that it
could be suspended from the girdle or habit cord
of a cleric, or from the belt. Many had covers of
stiff vellum sheathed in velvet, sometimes
overcast at the edges with silk thread, and
ornamented with balls and tassles. Such calendars
generally showed the saints' days and other
religious observances for each month, as well as
various astrological tables. They were generally
written on fold-out leaves of vellum. (347 )
