Final answer:
Abbot Suger was motivated by religious ideas such as the divinity of light, the concept of the church as a representation of Heaven on Earth, and the desire to express the growing power of the monarch. These ideas influenced the design of the choir of Saint-Denis.
Step-by-step explanation:
Abbot Suger was motivated by several key religious ideas in the design of the choir of Saint-Denis. One of these ideas was the belief in the divinity of light. Suger believed that light could transport people to a more heavenly and spiritual place, so he incorporated extensive use of stained glass windows in the choir to create an ethereal, illuminated space.
Another religious idea that motivated Suger was the concept of the church as an expression of the holy Jerusalem, a representation of Heaven on Earth. Suger wanted to create an architectural style that would honor both the royal occupants of Saint-Denis (the traditional burial place of French kings) and their God, so he aimed to make the church more ornate and grand.
A third religious idea that influenced Suger's design was the growing power of the monarch. Suger wanted to express the expanding power of the kings of France through the architecture of Saint-Denis. By creating a more elaborate and impressive design, Suger sought to symbolize the strength and authority of the monarchy.
