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.
Valley of the Kings The Valley of the Kings (Arabic: وادي الملوك‎ ‎ "Wādī al Mulūk" ), the "Valley of the Gates of the Kings" (Arabic: وادي ابواب الملوك‎ ‎ "Wādī Abwāb al Mulūk" ), is a valley in Egypt where, for a period of nearly 500 years from the 16th to 11th century BC, rock cut tombs were excavated for the Pharaohs and powerful nobles of the New Kingdom (the Eighteenth to the Twentieth Dynasties of Ancient Egypt).
