Artificial intelligence has revealed that a masterpiece by Raphael, 'The Holy Family with the Infant Saint John the Baptist,' hanging at the Museo Nacional del Prado, might have had contributions from other artists. Scientists used an AI algorithm to analyze the painting, and while the artwork is still largely attributed to Raphael, the figure of Joseph is believed to have been painted by a different artist. The revelation has sparked an interesting dialogue about the role of AI in art verification and authentication.
