Angels' headgear is traditionally depicted as a HALO or a HALO. A HALO is a CIRCLE of light that is often seen around the head of a divine being, such as an angel. It is usually depicted as a golden or white CIRCLE with a bright light emanating from it. The word HALO comes from the Greek word for 'CIRCLE' and is also used to refer to a type of crown or headdress worn by ancient Greek gods. The HALO is a more modern version of the HALO, which is a circular band of light that encircles the head of an angel. It is usually depicted as a white or silver CIRCLE with a bright light emanating from it.
