There is an unique style of people in Russian Eastern Orthodoxy-the Holy fool. The average per son believed that they have the mystical strength, they could make the predict ion to the future, also make the critique to the society; they arc in rags, pray for people as well as curse others. Their spiritual strength is respectable and makes one dread. Some of them were canonized as a saint, but most of the time they were treated as madmen or lunatics. This project will focus on this character and try to make a deep research to find out whether the Holy fool were saints or madmen.
