Fun aspect of ancient history is when you look for political or cultural accounts the historians all say "no one can really say if this took place, or if this guy really existed, but we know that around this time a person may have instituted a policy of some sort that might have ..." and then when they're talking about a battle suddenly the detail level skyrockets and its like "thirteen guys moved in on the left, it was drizzly out, this spearman was left-handed, he ordered them to flank on the right and then changed his mind a few seconds later..." etc. Its the historical version of intuiting an artists fetish by how hyper-detailed the feet are in an otherwise totally normal drawing
I wonder how much of this is down to the historians today assembling the information or the people in ancient times not bothering to write down anything that happened unless it was cool
