Abstract

From February to May 2025, Lambeth Palace Library hosted Unfolding Time: The Medieval Pocket Calendar. The exhibition brought together a rare and remarkable type of medieval folded book for the first time—the concertina-fold almanac—and set them alongside treasures from Lambeth’s own collection. Folded in a zigzag pattern to form a neat, easily transportable packet of information, their playful form is emphasised by their colourful and almost entirely pictorial content, all of which relates to time.
