Nimrud lens

From Wikipedia, the free encyclopedia

The Nimrud lens is a 3000 year old piece of rock crystal, which was unearthed by Austen Henry Layard at the palace of Nimrud in what is now Iraq (originally in Assyria).^[1] It may have been used as a magnifying glass, or as a burning-glass to start fires by concentrating sunlight. Assyrian craftsmen made intricate engravings, and could have used such a lens in their work.^[1]

Italian scientist Giovanni Pettinato of the University of Rome has proposed that the lens was used as part of a telescope by the ancient Assyrians.^[1] This would explain why the ancient Assyrians knew so much about astronomy. Experts on Assyrian archaeology are unconvinced, and doubt that the optical quality of the lens is sufficient to be of much use. The ancient Assyrians saw the planet Saturn as a god surrounded by a ring of serpents, which Pettinato suggests was their interpretation of Saturn's rings as seen through a telescope.^[2] Other experts say that serpents occur frequently in Assyrian mythology, and note that there is no mention of a telescope in any of the many surviving Assyrian astronomical writings.^[1]

The Nimrud lens is on display in the British Museum.

"If one Italian scientist is correct then the telescope was not invented sometime in the 16th century by Dutch spectacle makers, but by ancient Assyrian astronomers nearly three thousand years earlier. According to Professor Giovanni Pettinato of the University of Rome, a rock crystal lens, currently on show in the British museum, could rewrite the history of science. He believes that it could explain why the ancient Assyrians knew so much about astronomy."

They saw more in the night sky than was possible with the naked eye alone. For example, the Assyrians saw the planet Saturn as a god surrounded by a ring of serpents. Pettinato says that would be a logical assumption to make if they saw Saturn's rings through a primitive telescope."
