The most likely locale for Thule is nowadays considered to be the coast of Norway; other historians think it is the Shetland Islands, Faeroer or Iceland, however. In the Middle Ages, the name was sometimes used to denote Iceland.
Some Occult groups, most notably the German Thule Gesellschaft (ca. 1920) thought that it was the original source of the secret wisdom of the Aryan race.
Thule was also mentioned by Traditionalist author Julius Evola in connection with Hyperborea (literally, far north) and Atlantis.
The Romans used the phrase Ultima Thule to denote a distant unknown place.
