The Fraumünster church in Zurich, Switzerland, founded in 853, is known for its five large stained glass windows created by Chagall in 1967. Each window is tall by wide. Religion historian James H. Charlesworth notes that it is "surprising how Christian symbols are featured in the works of an artist who comes from a strict and Orthodox Jewish background." He surmises that Chagall, as a result of his Russian background, often used Russian icons in his paintings, with their interpretations of Christian symbols. He explains that his chosen themes were usually derived from biblical stories, and frequently portrayed the "obedience and suffering of God's chosen people." One of the panels depicts Moses receiving the Torah, with rays of light from his head. At the top of another panel is a depiction of Jesus' crucifixion.
