Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE EAGLE AND THE FARMER
An eagle was caught by a farmer but the farmer let him go when he realized what
he had caught. The eagle did not forget this good deed, and when he saw the
farmer sitting under a wall that was on the verge of collapsing, he snatched
the bandana from the man's head, wanting to rouse the man from his seat and
make him stand up. After the man set off in pursuit, the kindly eagle dropped
what he had snatched and thus fully repaid the man's good deed: the man would
have been crushed by the wall's collapse if he had stayed there any longer.
After a while the man came back to where he had been sitting and found that
the upright section of the wall had fallen to the ground.
This fable shows that if anyone does you a favour you must repay them in
