Archaeological evidence has been found of settlers living on the Faroe Islands in two successive periods prior to the arrival of the Norse, the first between 400 and 600 AD and the second between 600 and 800 AD. Scientists from Aberdeen University have also found early cereal pollen from domesticated plants, which further suggests people may have lived on the islands before the Vikings arrived. Archaeologist Mike Church noted that Dicuil (see below) mentioned what may have been the Faroes. He also suggested that the people living there might have been from Ireland, Scotland or Scandinavia, with possibly groups from all three areas settling there.
