Halo

Halo (optical phenomenon)

A halo is an optical phenomenon produced by light interacting with ice crystals suspended in the atmosphere. Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky. Many of these appear near the Sun or Moon, but others occur elsewhere or even in the opposite part of the sky. Among the best known halo types are the circular halo, light pillars, and sun dogs, but many others occur; some are fairly common while others are extremely rare.

Halo (religious iconography)

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.
