French artisan who is credited with the design and construction of the most famous of the three rose windows that adorn Notre Dame Cathedral in Paris. This beautiful rose medallion stained-glass window, entitled "The Glorification of the Virgin" and attributed to de Chelles, was added to the north face of the massive cathedral in 1240-45. In addition to the rose window, de Chelles also added a bay and elaborate façade to create the north transept and began construction on a bay and south transept, which were finished under the direction of another artisan, Pierre de Montreuil.
