The Icelandic sagas of the Norse people are thousand-year-old chronicles of brave deeds and timeless romances, but how true to Viking life were they? Writing in Significance, Pádraig Mac Carron and Ralph Kenna use a statistical network of associations between characters to find out.
While the stories involve a cast of thousands, recurring characters have emerged as the stories passed into historical legend. A set of recurring characters living within the same fictional world is not restricted to ancient stories, such as the Norse or Greek myths, but remains a popular device in modern comic and film franchises.
By exploring the number of ‘too-good-to-be-true’ interactions between protagonists, the researchers built a network of recurring characters which in turn could help reveal if the stories are invented or if they are based on a real society.
