An Ancient Lens That May Prove The Assyrians Used Optics

Unearthed in Iraq in 1850, the Nimrud Lens, a 3,000-year-old piece of rock crystal, offers a tantalizing glimpse into ancient Assyrian technology.

This small artifact has the potential to significantly alter our perception of scientific knowledge in the ancient world.
