How did the Rosetta Stone Help Decipher Egyptian Hieroglyphs?

After being discovered in Rosetta, Egypt, in 1799, the Rosetta Stone features a decree issued in 196 BCE inscribed in Greek, Demotic, and Hieroglyphic scripts. Because scholars could already read ancient Greek, they used the Greek text as a reference to decode the other two scripts.

The real breakthrough in the Rosetta Stone deciphering came on September 27, 1822, when French scholar Jean-François Champollion realized that hieroglyphs were not just symbolic but also phonetic. In other words, they represented both sounds and ideas.


For example, Champollion compared the repeated names of rulers, such as "Ptolemy" and "Cleopatra," across ancient Greek and Egyptian texts, as well as being able to match hieroglyphic signs to specific sounds and words.


This major discovery allowed scholars to read thousands of inscriptions from ancient Egypt, closing up a centuries-old mystery on ancient Egyptian history, religion, and daily life.
