Heoroweard and Hrólfr Kraki, by Jenny Nyström

Hrólfr Kraki, Hroðulf, Rolfo, Roluo, Rolf Krage (early 6th century  was a legendary Danish king who appears in both Anglo-Saxon and Scandinavian tradition. His name would in his own language (Proto-Norse) have been *Hrōþiwulfaz (famous wolf).

Both traditions describe him as a Danish Scylding, the nephew of Hroðgar and the grandson of Healfdene. The consensus view is that Anglo-Saxon and Scandinavian traditions describe the same people. Whereas the Anglo-Saxon Beowulf and Widsith do not go further than treating his relationship with Hroðgar and their animosity with Froda and Ingeld, the Scandinavian sources expand on his life as the king at Lejre and on his relationship with Halga, Hroðgar’s brother. In Beowulf and Widsith, it is never explained how Hroðgar and Hroðulf are uncle and nephew, but in the Scandinavian tradition, Halga conceived Hroðulf by raping Yrsa, not knowing that she was his own daughter.
