Ragnor Lothbrook is a legendary Viking figure who straddled the line between myth and reality. His adventures and deeds appear in the Viking sagas, but there is little hard evidence for his existence and according to the different sagas he dies on multiple different occasions and in a variety of grisly ways. His sons including Ivar the Boneless, Halfdan Ragnarsson, Björn Ironside, Ubbe and Sigurd Snake-in-the-Eye are undoubtedly real historical figures and themselves lived extraordinary lives. Was Ragnar really their father though or were these men trying to harness the power of legend by claiming descent from this great figure? To help explore that question Dan is joined by historian and author Justin Pollard. Amongst many other exciting projects, Justin was the historical advisor on the hit show Vikings which brought the story of Ragnar Lothbrok into the popular consciousness. Just and Dan discuss what evidence there is for the existence of Ragnar Lothbrok, the lives of his sons and how he goes about creating historical drama.
