What is the theme in The Vinland Sagas: The Norse Discovery of America ?

Discovery of the New World is the main theme. Medieval Norwegians had an unusual penchant for exploration. Most medieval communities were composed of serfs with few life prospects. The vast majority of Europeans would rarely leave their city-states, much less their countries. Widespread emigration not forced by conquest or circumstance is a phenomenon much more characteristic of later centuries. One impressive feature of the Vinland Sagas is the presentation of Norwegian and Icelandic elites as bold explorers long before their time, possessing a degree of individuality largely unknown during their time period.
