There at least used to be some (more than one) forum over on Delphi Forums, run by Roman Piso. Another howler (related to that ridiculous hoax “theory”) was a short-lived (perhaps by the same joker, or perhaps concocted as an elaborate lampoon) “theory” that the Roman Empire was hoaxed ad hoc, as a way to justify the Venetian Empire of the late medieval and the Renaissance. Imagine, Hadrian’s Wall wasn’t built by Hadrian, because there never was a Hadrian. Of course, the wacky “New Chronology” out of Russia (not related to the New Chronology by David Rohl) claims that King Arthur was actually a Russian, that whole dynasties in England were really distorted versions of earlier Byzantine rulers, etc etc.
