He who demands payment for a service from the wicked errs twice:
First, because he helps those who do not deserve it, and then because he can no longer get away with it
without harm.
The wolf, while swallowing, had stuck a bone in his throat; not being able to stand the pain, he began to lure the animals, one by one, with the mirage of a reward, so that they would get rid of that torment. In the end the crane was persuaded by force of oaths and, entrusting to the wolf's throat the entire length of his neck, he performed the dangerous operation. At the claim of the agreed prize the wolf
said: "You are really ungrateful; you managed to take the head out of my mouth and you still come to ask for the reward".
[ Qui pretium meriti ab improbis desiderat,
Bis peccat: primum quoniam indignos adiuvat;
Impune abire deinde quia iam non potest.
Os devoratum fauce cum haereret lupi,
Magno dolore victus coepit singulos
Illicere pretio, ut illud extraherent malum.
Tandem persuasa est iure iurando gruis,
Gulaeque credens colli longitudinem,
Periculosam fecit medicinam lupo.
Pro quo cum pactum flagitaret praemium:
«Ingrata es» inquit «ore quae e nostro caput
Incolume abstuleris et mercedem postules» ]
