Final answer:
Abbot Suger was motivated by verticality and light, classical Greek architectural forms, symmetry and balance in 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 emphasis on verticality and light. Suger believed that light equated to God and saw the use of light in the design as a metaphor for the presence of God. Another value reflected in Gothic buildings is the utilization of classical Greek architectural forms. Gothic architecture incorporated pointed arches, ribbed vaults, and flying buttresses. Lastly, Gothic buildings emphasized symmetry and balance, as seen in the overall design and layout of the choir of Saint-Denis.
