Fanlights
were first introduced in the 1720's. Adding Fanlights and glazing into
doors enabled more light to enter the previously dark hallways. Georgian
designs first started with glass being set within wooden or metal semi-circular
frame. Designs became more elaborate as metal work techniques improved.
Rectangle frames became popular in late Georgian designs.
