The Ecbasis captivi (full title: Ecbasis cuiusdam captivi per tropologiam, "The escape of a certain captive, interpreted figuratively") is an anonymous Latin beast fable that probably dates to the middle of the 11th century,[1] and was likely written in the Vosges region of France.
The wolf suggests that the fox should be hanged for his failure to appear and offer a cure.
He offers his cure: flay the wolf and let the lion use his skin as a blanket.
Then, the wolf shows himself to the assembled crowd of animals, which allows the calf to escape.
[7][8] Henry Hallam has written that the poem is unique, not only because it is the first new beast fable to appear in the European Middle Ages, but also because it unites the classical tradition of anthropomorphic fables such as Aesop with the allegorizing Christian bestiary tradition exemplified in the Physiologus and similar popular works.
