Rosetta Stone decree
The Rosetta Stone decree, also known as the Memphis Decree, is an official Ptolemaic edict issued on 27 March 196 BC by a synod of Egyptian priests assembled at Memphis to honor King Ptolemy V Epiphanes for his suppression of native revolts and benevolence toward the temples, establishing his divine cult and granting the priesthood tax exemptions, increased stipends, and financial support for religious institutions.[1][2][3]
Composed in the tradition of prior honorary decrees such as those of Canopus and Raphia, it praises Ptolemy V's coronation, military victories, and policies like debt remission and temple restoration, while mandating the erection of commemorative stelae in temples across Egypt.[4][1]
The decree's inscription in three scripts—hieroglyphic, demotic Egyptian, and Koine Greek—facilitated its dissemination in a multilingual society, with multiple copies produced, one fragmentary example of which, discovered in 1799, proved instrumental in deciphering ancient Egyptian writing.[1][2]
