Clip | Carthage's Lost Warriors - Examining the petroglyphs on the Rock of the Ingá

Countless figures and symbols have been engraved into the monolith since the Itacoatiara culture existed in Rio Paraíba. At an early stage local archaeologists noticed that many of the petroglyphs on the Rock of the Ingá displayed similarities with writing from the Old World in classical times.
