What does the term "lux nova" refer to in Gothic architecture?

The term "lux nova," which translates to "new light," is specifically associated with the way light is utilized and experienced in Gothic architecture, particularly through the use of stained glass windows. In Gothic cathedrals, large and colorful stained glass windows allowed natural light to pour into the interiors, creating a mystical and otherworldly atmosphere that was integral to the spiritual experience of the space. This innovative use of light was viewed as a manifestation of divine presence and played a crucial role in elevating the aesthetic and liturgical significance of churches during the Gothic period.

The other options relate to different aspects of art and architecture, but "lux nova" distinctly captures the essence of light as it interacts with the architectural elements of Gothic cathedrals and enhances the spiritual ambiance of the interior.
