- Contains 12 Calendar Pages from "The Calendar of the Prayer Book" by J. Parker, 1866.
- Contains an added introduction and a brief guide to further reading.
The calendar pages display 50 symbols from medieval clog almanacs, wooden calendars which were used before the invention of printing. They helped uneducated people keep track of Christian festivals and to calculate the phases of the moon. Those who used clog almanacs may not have been able to read but they knew the Bible and they knew stories about the saints.
