Bisclavret

"Bisclavret" ("The Werewolf") is one of the twelve Lais of Marie de France written in the 12th century. Originally written in French, it tells the story of a werewolf who is trapped in lupine form by the treachery of his wife. The tale shares a common ancestry with the comparable "Lay of Melion", and is probably referenced in Sir Thomas Malory's "Le Morte d'Arthur" with the tale of Sir Marrok, who has a similar story.
Background.
Marie de France claimed that she translated this lay, as well as the other eleven she wrote, from the Breton language, in which she claimed to have heard them performed. There have been many translations of her work into the English language, the translation noted below was done by Eugene Mason.
Synopsis.
Bisclavret, a baron in Brittany who is well loved by the king, vanishes every week for three full days. No one in his household, not even his wife, knows where he goes. His wife finally begs him to tell her his secret and he explains that he is a werewolf. He also says that while in werewolf form he needs to hide his clothing in a safe place so he can return to human form. The baron's wife is so shocked by this news that she tries to think of ways she can escape her husband. She does not want to "lie beside him any more". She conspires with a knight who has loved her for a long time. The following week, the baron's wife sends the knight to steal her husband's clothing. When her husband fails to return, she marries the knight. The baron's people search for him but finally relent, feeling that their absentee ruler has left for good.
A year later, the king goes hunting and his dogs corner Bisclavret, now fixed in wolf form. As soon as he sees him, Bisclavret runs to the king to beg for mercy by taking the king's stirrup and kissing his foot and leg. This behavior so astounds the king that he has his companions drive back the dogs and everyone marvels at the wolf's nobility and gentleness. The king takes Bisclavret, still in wolf form, back to the castle to live with him.
The knight who had married Bisclavret's wife is invited to the castle for a celebration along with all the other barons. As soon as he sees him, Bisclavret attacks the man. The king calls to Bisclavret and threatens him with his staff. Because he never acted so violently before, everybody in the court thinks the knight must somehow have wronged the wolf. Soon after, the king visits the area where the baron used to live and brings the werewolf along with him. Bisclavret's wife learns of the king's arrival and takes many gifts for him. When he sees his former wife, nobody can restrain Bisclavret. He attacks her, tearing off her nose.
A wise man points out that the wolf had never acted so before and that this woman was the wife of the knight whom Bisclavret had recently attacked. The wise man also tells the king that this woman is the former wife of the missing baron. The king has the wife questioned under torture. She confesses all and yields up the stolen clothing. The king's men put the clothing before the wolf, but he ignores it. The wise man advises them to take the wolf and the clothing into a bedchamber and let Bisclavret change in privacy. Bisclavret does so, and when he again sees him, the king runs to his beloved baron and embraces him, giving him many kisses. The king restores Bisclavret's lands to him and exiles the baroness and her knight. Many of the wife's female progeny were afterwards born without noses and all of her children were "quite recognizable in face and appearance."
The word "Bisclavret".
In the first part of the poem, Marie de France seems to use the Norman French word for werewolf, "garwaf", interchangeably with the Breton term, "bisclavret". However, she draws a distinction between ordinary werewolves and Bisclavret. One scholar specifies three evidences for this. "First, [Marie de France's] statement implies that he is unlike the violent werewolves that she has just described; second, her use of the definite article combined with the fact that Bisclavret is capitalized also implies that he is unique, that he is perhaps the only Bisclavret. Finally it is also noteworthy that Marie uses the term "garwalf" when describing the traditional werewolf. She thus once again distinguishes it from Bisclavret."
Influence.
"Bisclavret" was translated into Old Norse as "Bisclaretz ljóð", one of the "Strengleikar". Circulating in Iceland, it was much adapted, becoming "Tiódels saga".
In popular culture.
Hungarian heavy metal band Altar of Storms used the story as inspiration for their song Bisclavert (Werewolf's Night) on their 1999 demo Shreds.
