The Rosetta Stone is one of the most important objects in the British Museum as it holds the key to understanding Egyptian hieroglyphs—a script made up of small pictures that was used originally in ancient Egypt for religious texts.
The Rosetta Stone is special in the modern day because it gave modern day humans a way to decipher the Ancient Egyptian language.
Explanation:
For centuries, the Ancient Egyptian language was gone. Then, in 1799 the Rosetta Stone was discovered. It contained the same text three times, once in Ancient Greek, once in Demotic (a mix of Greek and Egyptian from when Greeks ruled Egypt), and once in Ancient Egyptian. Nobody knew what the Egyptian words meant, but they DID know the Greek words. Using those Greek words, the Egyptian tongue was slowly deciphered.
The actual text on the Stone isn't very important, but the languages used on it and the fact that they all say the same thing is very important.
