In the Old English epicBeowulf Ongentheow is described as a fearsome warrior and it took two warriors Eofor and Wulf Wonreding to take him down. The epic tells that the Geats under their new king Hæþcyn captured the Swedish queen, but old king Ongenþeow saved her, at a hill fort called Hrefnesholt, although they lost her gold. Ongentheow killed Hæþcyn, and besieged the Geats at Hrefnesholt. The Geats were, however, rescued by Hygelac, Hæþcyn's brother, who arrived the next day with reinforcements. Having lost the battle, but rescued his queen, Ongenþeow and his warriors returned home. However, the war was not over. Hygelac, the new king of the Geats, attacked the Swedes. The Geatish warriors Eofor and Wulf fought together against the hoary king Ongenþeow. Wulf hit Ongentheow's head with his sword so that the old king bled over his hair, but the king hit back and wounded Wulf. Then, Eofor retaliated by cutting through the Swedish king's shield and through his helmet, giving Ongentheow a death-blow. Eofor took the Swedish king's helmet, sword and mail and carried them to Hygelac. When they came home, Eofor and Wulf were richly awarded, and Eofor was given Hygelac's daughter. Because of this battle, Hygelac is referred to as Ongentheow's slayer. Ongentheow is also mentioned in passing by the earlier poem Widsith as the king of Sweden:
Egil
In Ari Þorgilsson's Íslendingabók and in Historia Norwegiae, he was called Egil Vendelcrow. Snorri Sturluson, however, gave the name Vendelcrow to Egil's son Ottar. In these sources, Egil was the son of Aun the Old, and like him, not very warlike. After he had made the thrall Tunni responsible for the treasury, Tunni rebelled against Egil. They fought eight battles after which Egil fled to Denmark, according to the Ynglinga saga. Snorri wrote that Fróði, the Danish king, aided Egil in defeating Tunni, and made Egil a tributary to the Danish king. Egil was killed by a bull during the sacrifices at Gamla Uppsala. The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation: The even earlier source Íslendingabók also cites the line of descent in Ynglingatal and it also gives Egil as the successor of Aunn and the predecessor of Óttarr: xvi Aun inn gamli. xvii Egill Vendilkráka. xviii Óttarr.
Interpretation
The argument for connection between Ongenþeow and Egil being the same figure are as follows. It is important, though, to note that this is an interpretation of the facts and not definite proof of a connection. The two versions seem contradictory, but it has been shown that the two stories may very well describe the same event, and that Ynglingatal was probably misinterpreted by Snorri due to a different dialectal meaning of the wordfarra. In Ynglingatal, it says If there is any authenticity behind the traditions, the origin of Ynglingatal was most probably a Swedish poem which has not survived. In Old Swedish, farra did not mean "bull" but it meant "boar". Moreover, in Old NorseTrjóna normally meant a pig's snout. Flæmingr meant "sword". Moreover, the sword of the snout can hardly refer tothe horns of a bull, but it is more natural to interpret it as the tusks of a boar. In English, the lines can be translated as but the giant beast coloured its tusk red on Egil. In Old English, the name eofor meant "boar" and consequently Ynglingatal could very well relate of Eofor killing Egil with kennings for boars. These kennings, sung originally by Swedes, were later misinterpreted by Norwegians and Icelanders as literal expressions due to the different dialectal meanings of farra. Moreover, according to Schück, the name Tunni which has no meaning in Old Norse should in Proto-Norse have been *Tunþa and derived from *Tunþuz. Consequently, it would have been the same word as the GothicTunþus which meant "tooth". This would mean that the name of Egil's enemy, actually meant "tooth" and Tunni and the bull/boar would consequently have been the same enemy, i.e. Eofor. Some scholars have suggested that the name Ongentheow is connected to the Danish king Ongendus, who appears in one sentence of Alcuin's life of Willibrord.
