  • "1. In architecture: A division, typically of stone, between the lights of windows, screens, etc. Mullions were first used toward the close of the twelfth century, and reached their most perfect development about the middle of the thirteenth century. In the later medieval architecture, while becoming constantly more elaborate in design and in moldings, and exhibiting much science in the methods of assembling, the mullions are artistically less satisfactory in their lines. The word is in the plural almost synonymous with tracery. See also cuts under batement-light, geometric, decorated, flamboyant.

    2. One of the divisions between panels in wainscoting. Formerly monial.

    3. To form into divisions by the use of mullions."
