How is an 'icon' defined in religious art?

In religious art, an 'icon' is best defined as a symbolic representation of a sacred personage. This definition aligns with the role of icons in various religious traditions, such as Christianity, where they serve to represent holy figures like Christ, Mary, and the saints. Icons are not merely images; they are imbued with spiritual significance and are often used as tools for veneration and meditation.

The term 'icon' implies a deeper connection beyond visual representation; it denotes an embodiment of the spiritual essence of the personage it represents. This ability to convey spiritual truths through a symbolic image distinguishes icons from ordinary religious art and emphasizes their importance in the context of worship and devotion.
