Sigurd Hlodvirsson (
circa 960 – 23 April 1014), popularly known as
Sigurd the Stout from the
Old Norse Sigurðr digri, was an
Earl of Orkney. The main sources for his life are the
Norse Sagas, which were first written down some two centuries or more after his death. These engaging stories must therefore be treated with caution rather than as reliable historical documents.
