The poem
Beowulf introduces
Hroðulf as kinsman. Later, the text explains that Hroðulf is Hroðgar's nephew and that "each was true to the other". Hroðgar is given three siblings, brothers
Heorogar and
Halga and an unnamed sister, all the children of
Healfdene and belonging to the royal
clan known as the
Scyldings. The poem does not indicate which of Hroðgar's siblings is Hroðulf's parent, but later Scandinavian tradition establishes this as Halga. Hroðgar and queen
Wealhþeow had two young sons,
Hreðric and Hroðmund, and Hroðulf would be their guardian in case Hroðgar dies. In a deliberately ironic passage it appears that the queen trusts Hroðulf, not suspecting that he will murder her sons to claim the throne for himself: No existence of any Hreðric or Hroðmund, sons of Hroðgar, has survived in Scandinavian sources (although Hreðric has been suggested to be the same person as Hroerekr/Roricus, a Danish king generally described as a son or successor of
Ingjald). This Hroerekr is sometimes said to have been killed by Hrólfr, vindicating the foreshadowing in
Beowulf. The Scyldings were in conflict with another
clan or tribe named the
Heaðobards led by their king
Froda and his son
Ingeld. It is in relation to this war that Hroðulf is mentioned in the other
Anglo-Saxon poem where he appears,
Widsith.
Hrólf and Hroðulf A common identification is that Hrólf Kraki is the same as the character Hroðulf (
Hroðgar's nephew) in
Beowulf. There seems to be some foreshadowing in
Beowulf that Hroðulf will attempt to usurp the throne from Hroðgar's sons
Hreðric and
Hroðmund, a deed that also seems to be referred to in
Saxo Grammaticus's
Gesta Danorum (Book 2), where we find: "... our king, who laid low
Rorik, the son of Bok the covetous, and wrapped the coward in death."
Rorik is the form we would expect
Hreðric to take in Danish and we find personages named
Rorik or
Hrok or similar in most version of the Hrólf Kraki tradition, but differently accounted for, seemingly indicating that Scandinavian tradition had forgotten who exactly
Hreðric/
Rorik/
Hrok was and various story tellers subsequently invented details to explain references to this personage in older poems. The future slaying of Hreðric may be the occasion of the future burning of the hall of
Heorot in the beginning of the poem – though some take it instead to refer to the legendary death of Hrólf Kraki, who in
Icelandic sources is said to have died in the burning of his hall by his brother-in-law
Hjörvard.
Beowulf and Bjarki The standard view is that, if
Beowulf himself has a 'cognate' character in Rolf Kraki's story, it is
Bödvar Bjarki (Bodvar Biarke), who also has a younger companion, Hjalti (Hialte) – perhaps matching the Beowulf character
Wiglaf. Beowulf comes from Geatland (=
Götaland) and one of Bödvar Bjarki's elder brothers,
Thorir, becomes a king of Götaland. Moreover, like Beowulf, Bödvar Bjarki arrives in Denmark from Götaland (Geatland), and upon arriving in Denmark he kills a beast that has been ravaging the Danish court for two years. The monster in
Hrólf Kraki's saga, however, is quite unlike the
Grendel of
Beowulf; but it does have characteristics of a more typical
dragon, a creature which appears later in
Beowulf. Just as Beowulf and Wiglaf slay a dragon at the end of
Beowulf, Bödvar Bjarki and Hjalti help each other slay the creature in Denmark. Proponents of this theory, like
J. R. R. Tolkien, argue that both the names
Beowulf (lit. "bee-wolf", a kenning for "bear") and
Bjarki are associated with bears. Bodvar Bjarki is constantly associated with bears, his father actually being one. In some of the Hrólf Kraki material, Bödvar Bjarki aids Adils in defeating Adils' uncle Áli, in the
Battle on the Ice of Lake Vänern. In
Beowulf, the hero Beowulf aids Eadgils in Eadgils' war against
Onela. As far as this Swedish adventure is concerned, Beowulf and Bödvar Bjarki are one and the same. This match supports the hypothesis that the adventure with the dragon is also originally derived from the same story.
Hrothgar and Hróar As for the king of the Danes,
Hroðgar, he is identical to
Hróar or
Ro, the uncle of Hrólf Kraki who in other sources outside of
Beowulf rules as a co-king with his brother Helgi. But in those sources it is
Hróar/
Hroðgar who dies before his brother or who departs to
Northumberland to rule his wife's kingdom leaving
Helgi/
Halga the sole rule of Denmark. In
Beowulf Halga/Helgi has died and Hroðgar is the primary ruler with Hroðulf son of Halga as a junior co-ruler. Furthermore, the Swedish kings referenced in Beowulf are adequately matched with the 5th and 6th century
Swedish kings in
Uppsala (see also
Swedish semi-legendary kings): This has obviously nothing to do with a common origin of the Beowulf and Hrólf Kraki legends in particular but simply reflects a shared genealogical tradition. ==
