What is an aureola in art terminology?

In art terminology, an aureola refers to a halo or nimbus, which is a luminous disk or ring that surrounds the heads of holy figures, symbolizing divinity or elevated status. This term originates from the word "aureole," which is often used to describe the radiant circle of light that indicates a sacred presence. The use of aureola imagery can be found across various cultures and time periods, often denoting important religious figures in Christian art, such as saints and the Virgin Mary.

The other options emphasize different aspects of art but do not capture the specific meaning associated with aureola. While a decorative frame can enhance artworks, it does not serve the same sacred or symbolic purpose as a halo. Similarly, a method of sculpture and a style of perspective refer to artistic techniques and approaches, which are entirely different concepts unrelated to the idea of a luminous or divine presence indicated by an aureola.
