Like the shadows on Judas’ face and the coin purse that he holds in the painting, the spilled salt is a reference to the fact that Judas will betray Jesus hours after the scene. For example, a container of salt lies, toppled, next to Judas’ right arm, because spilled salt was widely considered a bad omen. Narrative details in the painting stand out in the Giampietrino and Boltraffio version. Yet another copy, this one painted by Leonardo himself, was rediscovered in 2018 and likely created based on the same cartoon-a full-scale guide-as the mural. The students’ copy was even used as a reference when the original was restored between 19. The painting has been a useful resource for scholars because it is about the same size as the original Leonardo, though it lacks the top third of the piece, and it hasn’t faded as severely with time. The copy of The Last Supper held by the Royal Academy was likely created between 15 and is attributed to his pupils Giampietrino and Giovanni Antonio Boltraffio. In 1652, a doorway was cut through the mural, removing Jesus’ feet. But because of the technique that Leonardo used, as well as its poor treatment in the Dominican monastery in which it was painted (and where it's still visible today)-Napoleon used the room as a stable when he invaded Milan, according to a Google walkthrough of the new scan-many key details have faded or been lost. In the 1498 Leonardo work, each figure is depicted with a unique gesture and expression to reflect their reaction in the biblical story. Scenes of the Last Supper depict the moment when Jesus reveals that one of his 12 disciples will betray him. With the new scan, users can zoom into the image as if observing it from inches away, as artnet Newsreports. Google applied its Art Camera to scan The Last Supper, and 19 other works from the Royal Academy, in “gigapixel” resolution, creating a final image with over one billion pixels. Now, that oil painting is available online after a partnership between England’s Royal Academy of Arts and Google Arts & Culture, the latter says in a statement. Luckily, Leonardo’s pupils created a copy using oil paint on canvas that has better stood the test of time.


When he painted it, Leonardo used an experimental technique using egg tempera and oil paint on plaster, so it began to fade soon after it was completed. Leonardo da Vinci’s The Last Supper is a masterpiece.
