As for thinking the Rosetta Stone was a Spanish porn star *sigh* the Rosetta Stone was a basalt slab discovered in Rosetta at the western mouth of the Nile, during Napoleon's occupation of Egypt in 1799. It was the first trilingual monument discovered, displaying text in Egyptian hieroglyphics, demotic Coptic-style Egyptian language, and Greek and directly led to the decipherment of Egyptian hieroglyphics.
