On this occasion he came to Memphis by barge, in grand state, where he was met by the priests of Upper and Lower Egypt, and crowned in the temple of Phtah with the double crown, called Pschent, the crown of the two provinces. After the ceremony, the priests made the Decree in honour of the king, which is carved on the stone known by the name of the Rosetta Stone, in the British Museum. Ptolemy is there styled King of Upper and Lower Egypt, son of the gods Philopatores, approved by Phtah, to whom Ra has given victory, a living image of Amon, son of Ra, Ptolemy immortal, beloved by Phtah, god Epiphanes most gracious. In the date of the decree we are told the names of the priests of Alexander, of the gods Soteres, of the gods Adelphi, of the gods Euergetae, of the gods Philopatores, of the god Epiphanes himself, of Berenice Euergetis, of Arsinoe Philadelphus, and of Arsinoe Philopator. The preamble mentions with gratitude the services of the king, or rather of his wise minister, Aristomenes; and the enactment orders that the statue of the king shall be worshipped in every temple of Egypt, and be carried out in the processions with those of the gods of the country; and lastly, that the decree is to be carved at the foot of every statue of the king, in sacred, in common, and in Greek writing. It is to this stone, with its three kinds of letters, and to the skill and industry of Dr. Thomas Young, and of the French scholar, Champollion, that we now owe our knowledge of hieroglyphics. The Greeks of Alexandria, and after them the Romans, who might have learned how to read this kind of writing if they had wished, seem never to have taken the trouble: it fell into disuse on the rise of Christianity in Egypt; and it was left for an Englishman to unravel the hidden meaning after it had been forgotten for nearly thirteen centuries.
