The idea if is based on something mentioned by the Greek author Plutarch. Did they reach Canada in around AD56? A character in a text of Plutarch is said to have claimed he had recently returned from 'a great continent' – and that is about all the evidence is. What was a great continent in the eyes of the sailor. The newly conquered Britain (by the Romans) is bigger than your average Mediterranean island. Was it a reference to Britain and Ireland – as Greek sailors in AD56 may well have served in Roman boats. The researchers however choose another island – Newfoundland. There is no archaeology to support their theory – but there is evidence of the Vikings a thousand years later …
… there is no reason why Greek sailors, or Phoenicians come to that, may have stumbled upon the Americas – but AD56 appears to be a bit late for that.
