The design is derived from a medieval flushwork motif. Flushwork is a distinctive style of architectural decoration which was popular in the 14th Century, particularly in the South-East of England. It consists of decorative designs outlined in ashlar stone and then infilled with grey flint. It was used to adorn churches and important civic buildings, the designs often based on principles of sacred geometry or copying heraldic motifs.
