Answer:
We can decipher Hieroglyphics thanks to the Rosetta Stone.
Step-by-step explanation:
The Rosetta Stone is a large rock containing a decree issued during the Hellenistic period in Egypt (Ptolemaic Egypt).
The decree is written in two different hieroglyphic scripts, and also in Ancient Greek.
Because the Ancient Greek version of the script is the translation of the hieroglyphics, the Rosetta Stone became the key to translate the Ancient Egyptian Script.
