Nativity scene is a three-dimensional representation of the birth of Jesus created to commemorate this important Christian holiday. The origins of the nativity scene derive from medieval performances during which actors played important scenes from the life of Jesus or the saints. Saint Francis is considered to be the founder of this form of evangelization, he is credited with creating the first nativity scene in 1223. Over time, the tradition of mystery plays has been incorporated into folk culture, whereas the scenes with real actors have been transformed into a kind of puppet theater, accompanied by the procession of carol singers. At present, Polish cribs from Cracow and Italian cribs from Naples are the most popular.
