This rose window honors three figures of great significance in Christian history. Saint Gregory, one of the most influential popes, is known for his leadership in shaping the Church’s teachings and establishing Gregorian chant, which continues to inspire sacred music. Saint Cecilia, the patron saint of music, represents devotion and the power of worship through song, reflecting the deep connection between faith and the arts. King David, the shepherd-turned-monarch, was chosen by God to lead Israel and composed many of the Psalms that continue to be central to Christian prayer. Together, these figures symbolize leadership, devotion, and the enduring role of music in worship.
