A pediment is the triangular shape above a door or entrance. In a scroll pediment the ends of the sloping sides are shaped as a scroll, imitating paper or vellum. Where the sloping sides show a scroll only at the top, they are sometimes known as swan-neck pediments.
In addition, Canterbury door surrounds show good examples of scroll brackets – see images 3 and 4.
