Interesting take on the legend of Beowulf here courtesy of the Art of Manliness:
For the men of 10th century Europe, these were words to live by. Theirs was a time before the chivalric era, where knightly romance was hardly a dream and virtue and honor had yet to be made into a formal code of conduct. These were the men of the Dark Ages, members of the many Germanic tribes that once roamed across Northern Europe. Their code was a code not of chivalry, but of raw courage, in which strength of character was the greatest, and often the only reward.
