Thule (/ˈθjuːliː/; Greek: Θούλη, Thoulē), also spelled Thula, Thila, or Thyïlea, is, in classical European literature and maps, a region in the far north. Though often considered to be an island in antiquity, modern interpretations of what was meant by Thule often identify it as Norway, an identification supported by modern calculations. Other interpretations include Orkney, Shetland, and Scandinavia. In the Late Middle Ages and Renaissance, Thule was often identified as Iceland or Greenland. Another suggested location is Saaremaa in the Baltic Sea. The term ultima Thule in medieval geographies denotes any distant place located beyond the "borders of the known world". Sometimes it is used as a proper noun (Ultima Thule) as the Latin name for Greenland when Thule is used for Iceland.
