from Wikipedia Website. Thule as Tile on the Carta Marina by Olaus Magnus. Thule (also Thula, Thyle, Thile, Thila, Tile, Tila, Tilla, Tyle, or Tylenbeing Î¸Î¿ÏÎ»Î· in Greek) is in classic sources a place, usually an island. Ancient European descriptions and maps locate it either in the far north, often northern Britain or Scandinavia, or in the west and north, often Iceland or Greenland.
Stuart Fiedel gives the mainstream account of a migration that took around 100-150 years. The Thule culture, which is ancestral to recent Inuit or Eskimo groups, developed on the west coast of Alaska and spread by a swift coastal migration from northern Alaska to Greenland and Labrador (McGhee 1984). Thule people traversed this distance of about 1,500 to 2,000 miles in less than 150 years, between A.D. 900 and 1050 (fig. 7.1). 1
