Where was this produced?
The Morgan Bible is believed to have been produced in Paris, France under the rule of King Louis IX. Paris became the capital of manuscript illumination in France in the mid-thirteenth century. King Louis IX of France also commissioned the royal chapel known as the Sainte-Chapelle in Paris in the thirteenth century, around the same time as the Morgan Bible.
The Morgan Bible would likely have been produced in a decentralized workshop environment in Paris, where tasks could be distributed amongst several artists.
