Rosetta Stone, carved around 196 BC, found in 1799, let us understand Egyptian Hieroglyph.
The top part is Hieroglyph. Middle is Demotic. Bottom is Greek.
The Rosetta Stone is a granodiorite stele, found in 1799, inscribed with
three versions of a decree issued at Memphis, Egypt, in 196 BC during the
Ptolemaic dynasty on behalf of King Ptolemy V. The top and middle texts
are in Ancient Egyptian using hieroglyphic script and Demotic script, respectively,
while the bottom is in Ancient Greek. As the decree has only minor differences
between the three versions, the Rosetta Stone proved to be the key to deciphering
Egyptian hieroglyphs, thereby opening a window into ancient Egyptian history.
