Final answer:
A symbol in art represents an idea, concept, or emotion that the artist is trying to convey, adding layers of meaning to the artwork.
Step-by-step explanation:
A symbol in art represents an idea, concept, or emotion that the artist is trying to convey. It is not the interpretation of the overall meaning of the artwork, but rather a visual element used to communicate a deeper message. For example, in Leonardo da Vinci's painting 'The Last Supper,' the cup with wine may symbolize the blood of Christ. Symbols can add layers of meaning and enhance the viewer's understanding of the artwork.
