THE EAGLE AND THE LION AS PARTNERS
An eagle flew up to a lion and asked him to be his partner. 'I don't see why
not,' replied the lion. 'But first you must give me your long wing-feathers
as a pledge that you will keep your promise. How will I be able to trust you
as a friend if you do not stay here with me?'

You can find a compilation of Perry's index to the Aesopica in the gigantic appendix to his

in the Aesopic fable tradition. Invaluable.
