Page "Ivar the Boneless" Paragraph 25

* Ivar The Boneless appears in Harry Harrison's Hammer and Cross series which begins with the death of Ragnar and the invasion of the Heathen Army but then departs from historical events through the actions of the imaginary character Shef Sigvarthsson who eventually defeats Ivar in single combat.

Different characters offer different explanations for the appellation " the boneless "; some claim it refers to impotence, while others assert that it is because godar in shamanic trances see Ivar in the otherworld as a giant serpent.
