About halo

A halo, also called a nimbus, aureole, glory or gloriole, is a crown of light rays, circle or disk of light that surrounds a person in works of art. The halo occurs in the iconography of many religions to indicate holy or sacred figures, and has at various periods also been used in images of rulers and heroes. In the religious art of Ancient Greece, Ancient Rome, Christianity, Hinduism, and Buddhism, sacred people may be depicted with a halo in the form of a circular glow, or flames in Asian art, around the head or around the whole body—this last form is often called a mandorla.
