Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE ONAGER, THE DONKEY AND THE DRIVER
An onager saw a donkey standing in the sunshine. The onager approached the donkey
and congratulated him on his good physical condition and excellent diet. Later
on, the onager saw that same donkey bearing a load on his back and being harried
by a driver who was beating the donkey from behind with a club. The onager then
declared, 'Well, I am certainly not going to admire your good fortune any longer,
seeing as you pay such a high price for your prosperity!'
