The opinions as to the identity of ancient Thule have been numerous in the extreme. We may here mention six:—1. The common, and apparently the best founded opinion, that Thule is the island of Iceland. 2. That it is either the Ferroe group, or one of those islands. 3. The notion of Ortelius, Farnaby, and Schœnning, that it is identical with Thylemark in Norway. 4. The opinion of Malte Brun, that the continental portion of Denmark is meant thereby, a part of which is to the present day called Thy or Thyland. 5. The opinion of Rudbeck and of Calstron, borrowed originally from Procopius, that this is a general name for the whole of Scandinavia. 6. That of Gosselin, who thinks that under this name Mainland, the principal of the Shetland Islands, is meant. It is by no means impossible that under the name of Thule two or more of these localities may have been meant, by different authors writing at distant periods and under different states of geographical knowledge. It is also pretty generally acknowledged, as Parisot remarks, that the Thule mentioned by Ptolemy is identical with Thylemark in Norway.
