The top and middle texts are in Ancient Egyptian using hieroglyphic and Demotic scripts, respectively, while the bottom is in Ancient Greek. The decree has only minor differences across the three versions, making the Rosetta Stone key to deciphering the Egyptian scripts. The stone was carved during the Hellenistic period and is believed to have originally been displayed within a temple, possibly at Sais.
It was probably moved in late antiquity or during the Mamluk period , and was eventually used as building material in the construction of Fort Julien near the town of Rashid Rosetta in the Nile Delta. It was the first Ancient Egyptian bilingual text recovered in modern times, and it aroused widespread public interest with its potential to decipher this previously untranslated hieroglyphic script. Lithographic copies and plaster casts soon began circulating among European museums and scholars.
When the British defeated the French, they took the stone to London under the terms of the Capitulation of Alexandria in Since , it has been on public display at the British Museum almost continuously and it is the most visited object there. Study of the decree was already underway when the first complete translation of the Greek text was published in Major advances in the decoding were recognition that the stone offered three versions of the same text ; that the Demotic text used phonetic characters to spell foreign names ; that the hieroglyphic text did so as well, and had pervasive similarities to the Demotic ; and that phonetic characters were also used to spell native Egyptian words β Three other fragmentary copies of the same decree were discovered later, and several similar Egyptian bilingual or trilingual inscriptions are now known, including three slightly earlier Ptolemaic decrees : the Decree of Alexandria in BC, the Decree of Canopus in BC, and the Memphis decree of Ptolemy IV , c.
Though the Rosetta Stone is now known to not be unique, it was the essential key to the modern understanding of ancient Egyptian literature and civilisation. The term "Rosetta Stone" is now used to refer to the essential clue to a new field of knowledge. The Rosetta Stone is listed as "a stone of black granodiorite , bearing three inscriptions The Rosetta Stone is It weighs approximately kilograms 1, lb. The Rosetta Stone is a fragment of a larger stele.
No additional fragments were found in later searches of the Rosetta site. The top register, composed of Egyptian hieroglyphs, suffered the most damage.
