Read the text.

For a long time, historians faced a big issue when studying ancient Egyptian culture. No one knew how to read ancient Egyptian writing, which is called hieroglyphics. The answer to the puzzle came in 1799, when a soldier found a piece of rock called the Rosetta Stone. The Stone had a decree carved into it three times: once in hieroglyphics, once in ancient Greek, and once in another Egyptian writing system. Many people already knew how to read ancient Greek, so they used the text to figure out how to read the hieroglyphics.
