The term Labours of the Months refers to cycles in Medieval and early Renaissance art depicting in twelve scenes the rural activities that commonly took place in the months of the year. They are often linked to the signs of the Zodiac, and are seen as humankind's response to God's ordering of the Universe. The Labours of the Months are frequently found as part of large sculptural schemes on churches, and in illuminated manuscripts, especially in the calendars of late medieval Books of Hours. The manuscripts are important for the development of landscape painting, containing most of the first painting where this was given prominence. The most famous cycle is that painted in the early 15th century by Hermann, Pol and Johan de Limbourg in Tres Riches Heures du Duc de Berry. In the early 16th century, long after the term was established, the miniaturist Simon Bening produced cycles which link the Limbourgs with the landscape paintings of Peter Breughel the Elder.

A typical simple scheme was: January - Feasting February - Sitting by the fire March - Pruning trees, or digging April - Planting, enjoying the country or picking flowers May - Hawking, courtly love June - Hay harvest July - Wheat harvest August - Wheat threshing September - Grape harvest October - Ploughing or sowing November - Gathering acorns for pigs December - Killing pigs, baking However, there could be many other variations than the above, especially in major wine-growing areas, where more wine related scenes were included. Italian cycles often advance the agricultural scenes a month earlier than the ones from the Low Countries or England. The impact of the onset of the Little Ice Age has been detected in differences between early and late examples. Sculpture cycles Most sculptured cycles in Europe, especially when compressed into the archivolt of a portal, consist of an astrological symbol beside,
