crèche, in Christianity, a three-dimensional representation of the Nativity scene. Those represented usually include the infant Jesus in a manger, Mary and Joseph, animals, shepherds, angels, and the Magi. Although St. Francis of Assisi (1181/82–1226) is credited with popularizing it, devotion to the crèche probably existed earlier. Use of the crèche reached its zenith during the 17th and 18th centuries in southern Europe. It is still displayed in many churches, homes, and shops during the Christmas season, generally until Epiphany (January 6).
