How long was the rule of the dynasty that was active when the Rosetta Stone was inscribed?
Rosetta Stone 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.
Nanda Empire The Nanda dynasty originated from the region of Magadha in ancient India during the 4th century BCE and lasted between 345–321 BCE. At its greatest extent, the empire ruled by the Nanda Dynasty extended from Bengal in the east, to the Punjab region in the west and as far south as the Vindhya Range. The rulers of this dynasty were famed for the great wealth which they accumulated. The Nanda Empire was later conquered by Chandragupta Maurya, who founded the Maurya Empire.
