Ragnars sona þáttr
Also known as: Ragnars sona thattr, The Tale of Ragnar's Sons, Tale of the Sons of Ragnar


A short legendary saga recounting the deeds of Ragnar Loðbrók’s sons—especially their vengeance on King Ælla for Ragnar’s death—blending heroic genealogy, conquest narratives, and cunning stratagems.
Description
This þáttr (short tale) forms part of the Ragnar tradition, focusing on the exploits of Ragnar Loðbrók’s sons—Ívarr the Boneless, Björn Ironside, Hvitserk, Sigurðr Snake-in-the-Eye, and Ubbi—after their father’s death in Ælla’s snake pit. Guided at times by their mother Aslaug/Kráka, they wage campaigns across the North Atlantic and into England. Central episodes include Ívarr’s diplomatic ingenuity in Northumbria, the famous ox-hide ruse used to claim a fortress site, and the capture and execution of Ælla by the so-called blood-eagle. The narrative closes with the partition of realms among the brothers and etiological notes linking Scandinavian and Insular dynasties to the Ragnarsson line.
Historiography
Preserved within the legendary-saga corpus, the þáttr is an Icelandic prose compilation dependent on earlier oral traditions and cognate narratives (e.g., Ragnars saga loðbrókar, Saxo’s Gesta Danorum). Its historicizing details intersect with English and Irish annals that mention figures resembling Ívarr and Ubba, though episodes like the blood-eagle are debated. Manuscript transmission varies in scope and order, and later redactions harmonize genealogies with broader Scandinavian king-lists.
Date Notes
Legendary-material compilation; prose redaction likely in Iceland drawing on older Danish/English traditions.
