Luttrell Psalter pictures a scene from the Middle Ages that is included in the old testimony of the Bible. It shows the three different social classes, the Kings, one of the upper classes. The priests, a high class as well. And peasants, the lowest class. This piece of art is considered a primary source since it's the closest thing to a photograph that we are able to find from that era. This document is unique because, even though it wasn't the first document to show the rural life at that time, it is filled with amazing details about everything during that period in history.
