# Star polygons in art and culture

Star polygons and polygonal compounds are the basis for numerous figures of significance in arts and culture. The figure may be the border or interior of the polygon, or one or more closed polygonal paths that include all of the border and also have some legs crossing the interior. The name is derived from the polygon's similarity to the diffraction spikes of astronomical stars, but specific uses may exploit the connection or not. Stars often represent the unity of states within a country when they are used as a part of the flag.

## Emblematic use

* In heraldry, a mullet is a star with straight arms and typically five points. A star with wavy rather than straight rays is called an estoile. The mullet, used as an heraldic charge, is the ensign of knightly rank, and every order of knighthood incorporates this symbol in some way. It has traditionally been used in British heraldry as a mark of cadency for the third son.

The golden five-pointed star is a very common ideogram in the western world, and has particularly strong associations with military power and war. Many communist countries (such as China and Vietnam) and symbols also incorporate five-pointed stars.
