High Quality Content by WIKIPEDIA articles! The word quatrefoil etymologically means "four leaves", and applies to general four-lobed shapes in various contexts. In heraldic terminology, a quatrefoil is a representation of a flower with four petals, or a leaf with four leaflets (such as a four-leaf clover). It is sometimes shown "slipped", i.e. with an attached stalk. However, it is not defined as a flower, but called a "foil". In architecture and traditional Christian symbolism, a quatrefoil is a symmetrical shape which forms the overall outline of four partially-overlapping circles of the same diameter. The quatrefoil enjoyed its peak popularity during the Gothic Revival and Renaissance, but can still be seen on countless churches and cathedrals today. It is most commonly found as tracery, mainly in Gothic architecture, where a quatrefoil can often be seen at the top of a Gothic arch, sometimes with stained glass on the interior.
