Question

Quizplus · Accepted Answer

The addition of a transept actually helps to give the cathedral a more balanced and symmetrical appearance, rather than contributing to its perceived lightness and airiness. Flying buttresses and thin walls pierced by huge stained glass windows, on the other hand, are both key innovations that allowed for the use of pointed arches and ribbed vaults, which helped to distribute weight more efficiently and create the illusion of upward movement.
