If one searches long enough and hard enough, one can discover hints that just about any ancient culture you care to name set foot in the New World well before the Vikings and Columbus. Old coins, inscriptions, language concordances, and the like are taken by many as proofs that Egyptians visited Oklahoma, the Chinese moored along the Pacific coast, the Celts toured New England, and so on. Now, according to Professor V. Belfiglio, the ancient Romans had Texas on their itineraries.
Belfiglio's evidence is fourfold, and so are mainstream criticisms:
Roman coins found in Texas. The most convincing example came from the bottom of an Indian mound at Round Rock. This mound is dated at approximately 800 AD. Skeptics suppose that the coin was dropped on top of the mound in recent times and was carried to the bottom by rodents and tree roots. Hmmm!
The remains of a shipwreck. Circa 1886, the wreck of an unusual ship was found in Galveston Bay. Belfiglio says this ship's construction is typically Roman. Nautical experts doubt this. but they will admit that real Roman craft were perfectly capable of sailing to Texas.
The remains of an ancient bridge. Also in Galveston Bay, the timbers of an old bridge were found under 15 feet of sediment. A similar divergence of opinion prevails here.
Language concordances. Belfiglio has pointed out many similarities between Latin and a dialect of the now-extinct Karankawas tribe. No comment here from the language experts.
