Summing up: you say, the older a source seems to be, the more likely it is fake. I disagree. And I'm afraid we'll just have to leave it there.
As for the Tabula Peutingeriana, you're of course free to question its authenticity. But if your only piece of evidence for that is the fact it was "found" in the 18th century, well, then I will remain unconvinced. But maybe you should discuss this with the experts over in the "Medieval history" section. I may be biased after all the Napoleonic memoirs I've read only to figure out that many of them are of rather questionable authenticity.
