B.) It provides an opportunity to decipher the unknown hieroglyphs by matching them to the known Greek language.
The Rosetta Stone is a famous ancient artifact that played a crucial role in deciphering Egyptian hieroglyphs. It contains a decree issued by King Ptolemy V in three different scripts: hieroglyphs, demotic script, and ancient Greek. At the time of its discovery, hieroglyphs were largely undecipherable, as the knowledge of how to read them had been lost for centuries. However, scholars already knew how to read ancient Greek.
By having the same text inscribed in both hieroglyphs and Greek on the Rosetta Stone, it provided a key to unlock the meaning of the hieroglyphs. Scholars could compare the known Greek text to the unknown hieroglyphic text and identify corresponding words and phrases. This comparison allowed them to make educated guesses about the meaning of hieroglyphic symbols and eventually decipher the entire hieroglyphic script.
Therefore, the appearance of hieroglyphs and the Greek alphabet together on the Rosetta Stone created an opportunity for scholars to decode the mysterious hieroglyphs by utilizing the familiar Greek language as a reference point.
