Vatican scholar claims Leonardo da Vinci hid the date of the apocalypse in the painting "The Last Supper" Sabrina Sforza Galizia, who studied Da Vinci's manuscripts as a researcher at the University of California, claimed that the "end times" would begin on March 21, 4006, and end on November 1, 2010. According to her, there are clues hidden in the window above Jesus, but other than this claim, there is really no way to prove it.
The 15th-century polymath painted a number of apocalyptic scenes in a series called Visions of the End of the World.
