Leonardo Da Vinci’s masterpiece “Salvator Mundi” shows Jesus Christ holding a glass orb. However, in the painting, dated around 1500 CE, there are no signs of reflection from the glass orb. Rather, the painting shows Jesus holding a glass orb, enabling the viewer to see clearly through it. Scientists used advanced 3D rendering to study how light would reflect through various different types of orbs. The study revealed that Jesus is holding a hollow rather than a solid orb, which would have appeared the way that da Vinci depicted it. They also investigated Leonardo Da Vinci’s notes where he wrote broadly about the interaction between light and various objects.  He certainly used his understanding of optics and lights to build a true representation.
