Why was this made, and how was it used?
The Crusader Bible was probably made as a personal religious book for King Louis IX or as a gift for someone in his circle. The original manuscript had no text, so the pictures alone would guide the viewer through the story. By looking at the illustrations, the viewer could contemplate the story, its connection to their life, and their own connection to God.
The Crusader Bible was also used to underscore King Louis IX's power and wealth. A manuscript the size of the Crusader Bible would have required the killing of upwards of 50 calves to make parchment, a sizeable expense even before labor and other materials are factored in. King Louis's ability to purchase such a manuscript reflected on his own wealth. The content and style of the manuscript also highlight King Louis's political agenda. The scenes of the manuscript center the themes of power, leadership, and war. King Louis IX is linked to powerful biblical kings, particularly David, the king of the Israelites who established Jerusalem as the capital of Israel.
