Psalters, Breviaries and Books of Hours opened with a Calendar listing the religious events to be celebrated in the course of the year. Some other types of information, e.g. deaths in the family or suitable days for bloodletting, could also be contained in its text. In more luxurious copies of these texts, Calendar could be illustrated. This illustration usually consisted of two parts: the signs of the Zodiac and a survey of seasonal, mostly agricultural, activities. These are traditionally called the 'Labours of the Month'. For the gallery below, we have selected a typical activity for each month. Variations can be found by clicking the invitation to see more images.
