In 1316, the use of glass in architecture expanded significantly, particularly in the construction of cathedrals and public buildings across Europe. This innovation allowed for larger windows and more natural light, enhancing the aesthetic appeal of structures. The incorporation of glass transformed architectural design and the experience of space within buildings.

The increased use of glass in architecture inspired poets to explore themes of light, transparency, and the interplay of the physical and spiritual realms. The imagery of light filtering through stained glass became a powerful metaphor in poetry, influencing writers like Dante, who used such imagery to convey deeper philosophical and spiritual ideas. This connection between architecture and poetry enriched the cultural narrative of the time.
