Art Detectives: Forgery, Provenance, and the Science of Authentication (Osher Online)
Osher Online - Fall | Available (Membership Required)
The public often sees the art world as the domain of wealth, trendsetters, and high rollers, yet deception lurks behind the façade. After weapons and drugs, art is the third most lucrative illicit trade, with reports suggesting that more than half of artworks are fake or misattributed. In this course, we will ask: When is a copy simply a copy, and when is it a forgery? What techniques do master forgers use? Does a collector hold true title, and how important is provenance? What can science tell us about art authenticity? We will uncover riveting stories of criminal art activity, gallery closings, and master forgeries.
