saw the Rosetta Stone CD thread and it made me thing of the real thing. Basically, I understand it to be a tripartite stone in greek, demotic greek (?), and hieroglyph or something. people knew the 1st two, but not the 3rd.
how is the actual decryption process of the hieroglyph actually done? how do they know with a reason certainty that the translations they’ve developed (and eventually I guess there’s thousands of inscriptions translated over time that there’s no doubt???). I understand a similar process was done with Akkadian or something. I mean, at least with Shang inscriptions, there’s a little carryover with the script.
