THE SCENE: The Viking king Frothi was not above engaging in dueling during his leisure time activities, but doing so apparently cause him great annoyance.
THE TEXT: After these operations Frothi returned to his kingdom and was received with a banquet by a certain Skat, who meant to sweeten his king’s martial toils with some pleasurable relaxation. In his hall Frothi, lying regally on a couch upholstered in cloth and gold, was challenged to combat by one Hunding, and though his mind was bent on the joys of conviviality, exhilarated by the scent of battle more than the feast before him, he wound up the dinner with a duel, and the duel with victory. Although he had received a possibly dangerous wound, he was again stung to action [and] had two valets, who were clearly convicted of lese-majeste, drowned in the sea with great boulders attached to their bodies, a punishment to match a crime of weighty intent.
