This piece by Marc Chagall is called Calvary Christus gewidmet. It is an oil on canvas painting made in 1912. It is a painting dedicated to Christs crucifixion. This paint to me resembles both prayer because people are gathering at the foot of the cross praying for Christ. This painting by chagall is abstract, but it also has a subject point, we know what the painting is about, unlike most abstract paintings.
