Hrólf Kraki Tradition Onela was, according to Beowulf, a Swedish king, the son of Ongentheow and the brother of Ohthere.
He usurped the Swedish throne, but was killed by his nephew Eadgils, who won by hiring foreign assistance.
In Scandinavian sagas a Norwegian king by the same name exists, Áli (the Old Norse form of Onela, also rendered as Ole, Åle or Ale), who had the cognomen hinn Upplenzki ("from Oppland").
[11] By a conjectural emendation of line 62 of this poem some editors represent Onela as the son-in-law of Healfdene/Halfdan king of Denmark.
By the time Ynglingatal was used as a source by Snorri Sturluson, there appears no longer to have been a Scandinavian tradition of Áli as a relation of Eadgils.
[3] In Skáldskaparmál, compiled by Snorri Sturluson and in Arngrímur Jónsson's Latin summary of Skjöldunga saga, the battle hinted at in Beowulf is treated in more detail.
Snorri relates that much is told about this event in the Skjöldunga saga, and that Adils took Hrafn (Raven), Áli's horse.
