Through the interplay of light, color, and visual storytelling, these windows communicated Christian doctrine and reinforced the authority of both the Church and secular rulers to largely illiterate audiences. This essay explores the origins and expansion o
f stained glass across medieval Europe, examining its symbolic meanings and its role in shaping spiritual understanding and collective identity. By analyzing their iconography and cultural context, the study highlights how stained glass functioned as a visual medium that educated, inspired, and legitimized power within medieval society.
