Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
ZEUS AND THE ANT
Long ago, the creature who is today an ant used to be a man who was always busy
farming. Still, he was not satisfied with the results of his own labour, so
he would steal from his neighbours' crops. Zeus became angry at his greedy behaviour
and turned him into the animal that now has the name of 'ant.' Yet even though
the man changed his shape, he did not change his habits, and even now he goes
around the fields gathering the fruits of other people's labour, storing them
up for himself.
The fable shows that when someone with a wicked nature changes his appearance,
his behaviour remains the same.
