Leonardo da Vinci's "Salvator Mundi," c. 1500, was, for years, thought to have been destroyed. It was only re-discovered in the last five years and will go on public display for the first time in London in November.
Pictured is a detail from a mid-treatment photograph of the "Salvator Mundi." Through careful cleaning and infrared imaging, a "pentimento" or alteration in the composition of the blessing hand was found, leading scholars to believe that this was the work of da Vinci.
