Okay TruckKun, so I may have been too hard on you about the Damascus Steel part but, to even attempt to try and make Damascus Steel which no one knows how they made it. You would have to invent some stuff before you can try to make Damascus Steel. Like a Kiln and maybe even a blast furnace. Plus, I want to say a source of iron outside of iron meteorites, since finding enough to smelt it and steel, if that is possbile and make swords may be hard or not viable if you want to mass-produce it.   

And again, parchment has not been invented yet. That was invented in the 2nd century BC. So your char cannot just write down the blueprints for a galley. They would have to find something to write stuff down since your char would not have to know how to invent parchment.

What did they use for writing then? because when i looked it up all i could find was that they had advanced past the point of clay tablets/slate
