How old is the oldest written work where we have translated what is written on it in correctly that is verified?
Sigh. I've tried writing that sentence in a way that is understandable and am having trouble, which is fairly ironic. I guess I'm looking for the current demarcation of prehistory to history, but from the standpoint of writing that we have successfully translated beyond "we know someone wrote these symbols, but don't know what they were trying to say."
I've read the wiki page on prehistory and it says while in the past prehistory was 'that time before writing,' many historical scholars are moving beyond the writing and into artifacts. I'm currently interested in the oldest translated written works.
