Romeo Hristov argues that a Roman ship, or the drifting of such a shipwreck to the American shores, is a possible explanation of archaeological finds (like the Tecaxic-Calixtlahuaca bearded head) from ancient Rome in America. Hristov claims that the possibility of such an event has been made more likely by the discovery of evidence of travels by Romans to Tenerife and Lanzarote in the Canaries, and of a Roman settlement (from the 1st century BCE to the 4th century CE) on Lanzarote.
