for what it's worth, i saw and ignored this post when it was just the OP, you guys could have done the same
18th century is probably the nut low for accuracy in history and archaeology
and the real conspiracy theorists out there should not get behind analyzing the ancient greek texts but actually debunking them
much of what we have that is greek is translated from Arabic because we lost it and they preserved it and we later got it back from them so we have no idea what was lost or misinterpreted along the way - to my knowledge, this is the earliest known drawing of Socrates in existence
most of our intact texts are from the renaissance or later, much of them conflict with each other and we often just guess when do author attribution
for example, when in doubt, a scholar would just say "this is probably aristotle" so it got attributed to him, he'd have every incentive to do that as well because unearthing an unknown text by aristotle from a church archives in florence in 12th century would be a whole lot more momentous than unearthing a random and anonymous text
same for forgeries, if you're forging a document for fame or fortune to sell then it'll make a whole lot more sense to attribute it to someone with more name brand recognition

in fact, much of what someone in the 18th century who studied the classics would have studied has long since been proven as either falsely attributed or outright false itself
if you're going to go down rabbit holes based on ancient greece, the possibility that much of what we know is made up fiction is a whole lot more fun
fun fact, i learned all this stuff because i love ancient history and have read most of the original texts in english. I actually was such a fanboy that when I began researching which version of ancient greek to read the originals in, I soon discovered that most of the information we have on the Greeks can't be traced back to the Greek language itself but our earliest copy of it is in Arabic, Latin or some other language...
that's when i went down that historicity of greece rabbit hole and man... I do not recommend it, i'm sure many of you are already labeling me as a nutjob
