suppose that, during Napoleon's campaign in Egypt, a stray cannonball hits what would eventually be discovered as being the Rosetta Stone before it was ever realized as such; there could potentially be bits and pieces of it left behind, but its more or less unrecognizable rubble. what does everyone think the repercussions of this would be? obviously, egyptology is more or less completely unlike how it is IOTL, if it exists at all, with the primary source of hieroglyphic translation lost forever.
