The Jesse Tree was the only prophecy in the Old Testament to be so literally and frequently illustrated, and so came also to stand for the Prophets, and their foretelling of Christ, in general. Both the St-Denis and Chartres windows include columns of prophets, as do many depictions. Often they carry banderoles with a quotation from their writings, and they may point to Christ, as the foretold Messiah. The inclusion of kings and prophets was also an assertion of the inclusion and relevance in the biblical canon of books that some groups had rejected in the past.
