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. This establishes that manuscript illumination was a popular method at the time of King Louis IX’s reign in France; both the popularity of illuminated manuscripts and the reign of King IX can be attributed to mid-thirteenth-century France. The Morgan Bible, also, contained only illuminations on manuscripts that support the idea of the Bible being produced in thirteenth-century France, before the widespread literacy movement.
King Louis IX of France also commissioned the Sainte-Chapelle in the thirteenth century; believed to be the same decade as the Morgan Bible.
The modern clothing of the characters of the Bible is consistent with thirteenth-century apparel in France.
The “biblical kings wear crusader armor and have fleur-de-lis crowns and scepters, reinforcing the associations and royal patronage” which alludes to the apparel of thirteenth-century France at the time of the Crusades. The aggressive militant nature depicted in the Morgan Bible reigns true to the stance King Louis IX withheld to protect Christianity under his rule.
In a broader sense, the Morgan Bible would likely have been produced in a decentralized workshop environment, where tasks could be distributed amongst several artists.
