I'm looking for a word or term I heard once in a modern art class that refers to an art piece that contains multiple layers from different eras. The example used in the class that I distinctly recall is the following: imagine an ancient Roman artwork, which a Renaissance artist painted over, which a contemporary modern artist painted over, and now the layers from each period are becoming exposed.
A more metaphorical interpretation would be to imagine a modern movie, that references a silver screen movie, which in turn was an adaption of a Shakespearean play.
To my best recollection, I don't believe the term had to do with simulacra and referents (a la Baudrillard), but I may be mistaken, as I don't know much about that philosophy; rather, I think the term had to do with a specific physical technique or archaeological term. However, it's not impossible that the term was symbolic/philsophical.
