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.
Ashur-rabi II Aššur-rabi II, inscribed "aš-šur-""-bi", "(the god) Aššur is great," was king of Assyria 1012–972 BC. Despite his lengthy reign (41 years), one of the longest of the Assyrian monarchs, his tenure seems to have been an unhappy one judging by the scanty and laconic references to his setbacks from later sources.
