" A four-cornered cloth cap that is sometimes worn by Anglican clergy. It is soft, flat, and typically black in color. The Canterbury cap reflects a style of academic headgear that developed during the later middle ages. It served to keep the head warm in drafty lecture halls and churches. It is occasionally used by clergy today when ecclesiastical headgear is needed.
