During the Renaissance ideas, art, and architecture of Classical Antiquity were reborn. Architects of the Renaissance were fascinated by geometry and mathematics. All building elements were aligned proportionally, and building facades appeared stringent and rhythmical, with windows positioned to mirror the inside of the building. Often the windows were proportioned to fit within the house’s timber-frame.  

Renaissance windows consist of lead lights inserted in wooden casements. The glass is crown glass, or cylinder glass. The casements, transom and mullion are often decorated with carvings.
