We look back at three interviews about the most expensive painting ever sold at auction. In a short clip from a November 2017 chat, Judd Tully tells us about the atmosphere at Christie's as the Salvator Mundi sold. The Leonardo scholar Martin Kemp explains his view that the painting is a true Leonardo, in an interview from March 2018. And in a wide-ranging conversation from April 2019, Ben Lewis explores the painting's history and the continuing debates about its provenance, attribution and present whereabouts.
