Learning about Viking Age archaeology now -- just getting into it. York (or Jorvik, as it was known) yeilded a very rich site at Coppergate during the 1970s -- and that site also turned up features and artifacts dating back to the Angle's occupation (famously, the helmet), and a Roman garrison town.
But now I'm excited about the 1960s finds in Newfoundland, because a Swedish scientist has recently found a dental connection between Vikings and New World natives -- apparent ritual carving of the teeth.
This implies more than mere encounter. Some intimacy, mutual understanding, and communication may have existed between the two cultures for such a ritual act to be appropriated.
