I just finished reading 1984 and realized that the Rosetta Stone may have been created to preserve known history.
It had never occurred to me that an entire language and it’s nuances are necessary to maintain historic integrity. We may have been able to decipher hieroglyphs without a translator, but could we do it with precision enough to learn anything truthful. Can we do that now is a thoughtful question as well i guess.
I’m certain this is not an original thought, and only want to talk about the book. I think i heard somewhere that the stone was created for trade purposes as well.
AfaIk, the Rosetta stone contains a Ptolemic decree which was, to be broadly understood, usually published in all three official languages / writings in Ptolemic Egypt, i.e. Greek and ancient Egyptian in Hieroglyphs and Demotic writing.
