Given the significance of the notion of authenticity in preservation and restoration, the present study aims at investigating this concept and other related concepts (like value, integrity, and the artist’s intent) in the history of preservation and restoration. The article attempts to reconsider authenticity and determine various approaches regarding authenticity throughout the history of preservation and restoration. In doing so, the history of preservation and restoration is to be reviewed and explored. The qualitative method of research and content analysis strategies are employed to carry out the research. The study of concepts such as value, authenticity, integrity, artist’s intent, and the preservational-restorational approach in historical artifacts across time reveals that the values expressed in historical artifacts and cultural heritage are transformed by the particular philosophical perspectives, schools of thought, and events of each era. These factors have indirectly exerted influence on authenticity, integrity, artist’s intent, and eventually on the preservational-restoration approach.
