In 1211, Reims Cathedral became known for being the first Gothic cathedral to use bar tracery with rose windows. Besides, showing up later in Rhenish art around 1200, the circular window was almost never used in Romanesque architecture and never considered to be important for lighting. Early Gothic Style Example(s): Laon Cathedral (12th–13th centuries A.D.) 1180–90 marked the date for the two transept large rose windows which were made up of several juxtaposed multi-foils.
