Thūle

, an island in the most northern parts of the German ocean, to which, on account of its great distance from the continent, the ancients gave the epithet of ultima . Its situation was never accurately ascertained, hence its present name is unknown by modern historians. Some suppose that it is the island now called Iceland or part of Green land, whilst others imagine it to be the Shetland isles.
