Attribution of a Portrait to Leonardo da Vinci

Part of the Law, Governance and Technology Series book series (LGTS, volume 23)


In this chapter a case study is conducted to test the capability of the Carneades Argumentation System (CAS) to model the argumentation in a case where forensic evidence was collected in an investigation triggered by a conflict among art experts on the attribution of a portrait to Leonardo da Vinci. A claim that a portrait of a young woman in a Renaissance dress could be attributed to Leonardo was initially dismissed by art experts. Forensic investigations were carried out, and evidence was collected by art history experts and scientific experts. The expert opinions were initially in conflict, but new evidence shifted the burden of proof onto the side of the skeptics. This chapter presents an analysis of the structure of the interlocking argumentation in the case using argument mapping tools to track the accumulation of evidence pro and con.
