('''') and his sons,
Ivar and Ubba, worshipping pagan idols, as it appears on folio 39r of British Library Harley 2278. This illustration depicts the pagan Danes as elaborately dressed Muslim
Saracens, wearing tall
turban-like headdresses and forked beards. Other illustrations in the manuscript, depicting Ivar and Ubba, show Vikings armed with curved swords. Although Ubba and Ivar are associated with each other by
Passio sancti Eadmundi, the men are not stated to be related in any way. The earliest source claiming kinship between the two is the
Annals of St Neots, an 11th- or 12th-century account stating that they were brothers of three daughters of Lodbrok ('
). This source further states that these three sisters wove a magical banner named ' that was captured at the ''
conflict. Although certain versions of the Anglo-Saxon Chronicle
also note the capture of a raven banner, named '' ("Raven"), they do not mention any magical attributes, or refer to Lodbrok and his progeny. Lodbrok appears to be an early reference to
Ragnar Lodbrok, a
saga character of dubious historicity, who could be an amalgam of several historical 9th-century figures. According to Scandinavian sources, Ragnar Lodbrok was a Scandinavian of royal stock, whose death at the hands of Ælla in Northumbria was the catalyst of the invasion of Anglo-Saxon England—and Ælla's own destruction—by Ragnar Lodbrok's vengeful sons. None of the saga-sources for the legend of Ragnar Lodbrok accord him a son that corresponds to Ubba. The latter is only specifically attested by sources dealing with the East Scandinavian tradition. One of these sources is the 13th-century
Gesta Danorum. According to this text, Ubba was the son of Ragnar Lodbrok and an unnamed daughter of a certain Hesbernus.
Gesta Danorum does not associate Ubba with Anglo-Saxon England in any way. According to the 13th- or 14th-century
Ragnarssona þáttr, a source that forms part of the West Scandinavian tradition, Ivar had two
bastard brothers, Yngvar and Husto, who tortured Edmund on Ivar's instructions. No other source mentions these sons. It is possible that these figures represent Ivar and Ubba, and that the composer of
Ragnarssona þáttr failed to recognise the names of Ivar and Ubba in English sources concerned with the legend of Edmund's martyrdom. By the 13th century an alternate rendition of the story appears in sources such as
Chronica majora, and both the Wendover and Paris versions of
Flores historiarum. For example, the Wendover account states that Lodbrok ('
) washed ashore in East Anglia, where he was honourably received by Edmund, but afterwards murdered by Björn ('), an envious huntsman. Although the latter is expelled from the realm, he convinces Lodbrok's sons, Ivar and Ubba, that the killer of their father was Edmund. As such, East Anglia is invaded by these two sons, and Edmund is killed in a case of misplaced vengeance. A slightly different version of events is offered by
Estoire des Engleis, which states that the Vikings invaded Northumbria on behalf of Björn (''''), who sought vengeance for the rape of his wife by the Northumbrian king, Osberht. On one hand, it is possible that the theme of vengeance directed at Edmund is derived from the tradition of Ælla's demise in Northumbria at the hands of Ragnar's progeny. On the other hand, the revenge motifs and miraculous maritime journeys presented in the accounts of Edmund are well-known elements commonly found in contemporaneous
chivalric romances. There is reason to suspect that the legend of Ragnar Lodbrok originated from attempts to explain why the Vikings came to settle in Anglo-Saxon England. The core of the tradition may have been constructed as a way to rationalise their arrival without assigning blame to either side (as illustrated by the sympathetic Wendover account). As such, the legend could have been intended to justify Edmund's violent demise. The tales may have evolved at an early stage of Viking settlement, and may have functioned as an
origin myth of the emerging
Anglo-Scandinavian culture. The shared kinship assigned to Ivar and Ubba within the legend of Ragnar Lodbrok may stem from their combined part in Edmund's downfall as opposed to any historical familial connection. ==In popular culture==
