The word "halo" refers to a circular band of light that appears to surround a luminous body, such as the sun or moon. In a more figurative sense, it can also describe a glowing aura or quality that surrounds a person or thing, often suggesting holiness or virtue. The term is commonly used in religious art to denote the divine nature of a saint or angel.
The word "halo" originates from the Latin word "halōs," meaning "a circle" or "ring." It is also connected to the Greek word "haloe," which means "to shine." This reflects the visual aspect of a halo as a shining ring around an object.
