Gesta Danorum - Deeds of the Danes In the early years of the thirteenth century the Danish writer Saxo Grammaticus provided his people with a History of the Danes, an account of their glorious past from the legendary kings and heroes of Denmark to king Gorm. It is one of the major sources for the heroic and mythological traditions of northern Europe, though the complex Latin style and the wide range of material brought together from different sources have limited its use.
