The Rosetta Stone

Explanation:

The Rosetta stone was discovered in 1799. It was the most important discovery in relation to the interpretation of Ancient Egyptian since it contains a decree issued in 196 BCE in Egypt which contains three different sections, two of them using ancient Egyptian scripts and the other using ancient Greek. Fortunately, since the decree shows minor differences between the three sections, and since ancient Greek was decipherable, it became the key to decipher Egyptian hieroglyphs.
