Artificial intelligence (AI) can be trained to see details in images that escape the human eye. In 2023, an AI neural network identified something unusual about a face in a Raphael painting: It wasn't actually painted by Raphael. Scholars have, in fact, long debated whether or not the painting is a Raphael original. The method has previously been shown to have a 98 percent accuracy level when it comes to identifying Raphael paintings. "So, then we tested the individual parts and while the rest of the picture was confirmed as Raphael, Joseph's face came up as most likely not Raphael."
