Addressing one of the most controversial issues in the debate on the relationship between cultural heritage and public memory, this book goes to the heart of the so-called “cancel culture”, offering an interdisciplinary reading of today’s cultural revisionism in art history, art criticism, museology and museography. The volume offers an investigation of the processes of subtraction, forgetting and omission of artistic phenomena from material, narrative and symbolic perspectives. The result is a critical notion of “art history”, engaged with the tensions and upheavals of our past and present.
