Come and explore medieval concepts of the past, present and future through a rare and remarkable group of manuscripts: concertina-fold almanacs. Within the zigzag folds of these extraordinary books, time is vividly expressed in colourful pictures, poems, tables and devices.

With fewer than thirty manuscripts known to exist, this exhibition brings a group of them together for the first time and sets them alongside treasures from Lambeth Palace Library.

About Our Funders

Unfolding Time is made possible with The National Lottery Heritage Fund. Thanks to National Lottery players, we have been able to bring these precious manuscripts together, and make them freely accessible to the public.

The National Lottery Heritage Fund is the largest funder for the UK’s heritage. Using money raised by National Lottery players we support projects that connect people and communities to heritage. Our vision is for heritage to be valued, cared for and sustained for everyone, now and in the future. From historic buildings, our industrial legacy and the natural environment, to collections, traditions, stories and more. Heritage can be anything from the past that people value and want to pass on to future generations. We believe in the power of heritage to ignite the imagination, offer joy and inspiration, and to build pride in place and connection to the past.

Generous additional support comes from the Friends of Lambeth Palace Library.
