BIFORA. — This term refers to any window divided into two adjacent sections, generally separated by a small column and enclosed within a single architectural frame, whether arched or not. It already appears as a decorative element on the facades of Lombard churches of the 12th century (Pavia, S. Michele) and in others from Umbria and Apulia of the same period. It enjoyed greater popularity during the Gothic age and early Renaissance, taking on a wide variety of forms depending on the location, up to the characteristic examples at the Certosa of Pavia, where the dividing column is replaced by a candelabrum.
