Maravilla americana (Mexico, 1756): painters called as expert witnesses

On 30 April 1751 the collegiate chapter of the Guadalupe sanctuary outside Mexico City assembled the most credited painters of the city, took the glass off an image, and asked them to judge by the rules of their art whether it could be human work. Miguel Cabrera printed his report in 1756 with the signed statements of three of the men who were there. The same pages that record the examination record who convened it and what they wanted from it.
