Explanation:
The first consistent style was called Romanesque, which was at its peak between 1050 and 1200. Romanesque churches used art, largely painting and sculpture, to communicate important things
There are many artistic tasks that the monks and nuns performed at the time. Here are some of such options:
1. painters - given that they had some free time, monks and nuns resorted to painting to kill time
2. weavers - nuns would usually weave or embroider in order to create beautiful patterns of cloths
3. carvers - especially monks did this - carving wooden objects was a good way to both train and entertain themselves
