"Salvator Mundi" is a powerful painting believed to be by Leonardo Da Vinci, depicting Jesus Christ as "Savior of the World." It's incredibly valuable not just for its artistic merit, but also because it's one of fewer than 20 Da Vinci paintings known to exist. This painting famously sold at a Christie's auction in 2017 for an astonishing $450.3 million, making it the most expensive artwork ever sold. Its current location is often debated, though it's thought to be owned by the Saudi Royal Family.
