noun and verb. / əˈtriˌbyo͞ot /
1). An attribute is a symbol associated with a specific person, like a saint, that is used to identify them in art.
Example: According to Christian tradition, Saint Lucy was separated from her eyes before she was martyred. Therefore, the saint is depicted with a set of disembodied eyes as attributes.
2). When experts attribute a work of art to an artist, they certify that it is likely made by that artist -- likely but not definitely. Attribution is a step below authentication in certainty.
