Italy (Assisi)

Comprehensive In-Depth Stylistic and Historical Analysis of the Rose Window at the Upper Basilica of San Francesco in Assisi

2613

Italian Gothic period, constructed circa 1230–1253 CE (traditionally attributed to master architect and sculptor Fra Guglielmo da Pisa working alongside local Umbrian masons during the mid-13th-century construction campaign of the Upper Basilica).

Positioned high on the western facade, the window served to flood the nave of the Upper Basilica with divine, colored light (Lux Nova), illuminating the groundbreaking cycle of frescoes inside. Symbolically, it acted as a visual wheel of creation, a cosmic mandala, and a manifestation of Franciscan theology, which viewed the natural world and light as direct reflections of God's supreme beauty.
