These two were sore about their father Ragnar Lodbrok, who had shipwrecked in England — maybe East Anglia, maybe elsewhere — and allegedly been thrown into a snakepit.
According to the hagiographic account, these Danish heathens attempted to force Edmund to renounce Christianity. Edmund demurred.
Then those wicked men bound Edmund, and shamefully insulted him, and beat him with clubs, and afterwards they led the faithful king to an earth-fast tree, and tied him thereto with hard bonds, and afterwards scourged him a long while with whips, and ever he called, between the blows, with true faith, on Jesus Christ; and then the heathen because of his faith were madly angry, because he called upon Christ to help him. They shot at him with javelins as if for their amusement until he was all beset with their shots, as with a porcupine’s bristles, even as Sebastian was.
The martyr-king’s body was ultimately interred at the aptly-namd Bury St. Edmunds. This locale thereafter became a major, and lucrative, pilgrimage spot in Britain.
Edmund himself became the patron saint of England until he was supplanted just before the Norman invasion by omnibus patron saint George. As George had nothing to do with England, there’s been some latter-day push to revert the honor to the native king.
On an unknown date in (perhaps) the 860s, Norse raider Ragnar Lodbrok (or Ragnar Lothbrok) was allegedly put to death in the Indiana Jones-esque manner of being cast into a pit of snakes.
Ragnar is a half-legendary character who plundered France and Britain in the mid-ninth century, the heyday of Viking marauders; he’s also the lead character of the cable TV series Vikings.
He’s known from Scandinavian sagas, like the Ragnarssona Þattr, which describes Ragnar’s final battle after shipwrecking in Northumbria.
At that time, there was a king called Ælla ruling over Northumbria in England. And when he learns that raiders have come to his kingdom, he musters a mighty force and marches against Ragnar with an overwhelming host, and hard and terrible battle ensues. King Ragnar was clad in the silken jacket Aslaug had given him at their parting. But as the defending army was so big that nothing could withstand them, so almost all his men were killed, but he himself charged four times through the ranks of King Aella, and iron just glanced off his silk shirt. Finally he was taken captive and put in a snake-pit, but the snakes wouldn’t come near him. King Aella had seen during the day, as they fought, that iron didn’t bite him, and now the snakes won’t harm him. So he had him stripped of the clothes that he’d been wearing on the day, and at once snakes were hanging off him on all sides, and he left his life there with much courage.
Here’s Ernest Borgnine as Ragnar in the 1958 film The Vikings, dying in a pit full of wild dogs, not snakes. Well, it’s the same animal kingdom.
“How the little pigs would grunt if they knew how the old boar suffers!” he’s supposed to have exclaimed, keeping to the nature theme.
