In these drawings, architectural student Stammers records different styles of window from Ancient Egyptian, Greek and Roman examples through to Renaissance and Baroque windows. In the the 11th and 12th centuries, small windows were safer and less expensive. Later, as glass became cheaper to produce and times more peaceful, windows could become larger and more ornate. The opening was often divided by carved stonework called tracery. Windows usually had pointed arches but circular rose windows were also popular.
