From Unreported Heritage News, 23 December 2010:
New archaeological discoveries show that Iceland was inhabited around AD 800 – nearly 70 years before the traditional dating of its Viking settlement.
One possibility is that these early inhabitants may have been related to Irish monastic communities found throughout the Scottish islands at that time, and described in Viking-Age and medieval texts.
“Questions surrounding Iceland’s first settlement in the early medieval period have been of longstanding interest for scholars,” said Professor Kristján Ahronson of Prifysgol Bangor University in Wales and Visiting Professor at the University of Toronto. He led the team that made the discoveries.
