The Rosetta Stone was found by Napoleon’s soldiers in Egypt in 1799. It was read by Jean-François Champollion in 1822, and thus became the key to unlock Egyptian hieroglyphics. The Rosetta Stone is now displayed in the British Museum in London, where it has been since 1802.

Beautiful picture! I would love to see it someday. Thanks for sharing.
One of the highlights of my last trip to London was standing in front of the Rosetta Stone. Thanks for the memory.
