Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE CROW AND ATHENA
The crow was making a sacrifice to Athena and invited a dog to the feast. The
dog said to her, 'Why do you foolishly squander these sacrifices? The goddess
clearly hates you so much that she has taken away all credibility from your
omens.' The crow answered, 'That is all the more reason for me to sacrifice
to her: I hope she will change her attitude towards me!'
The fable shows that people are often eager to treat their enemies well
in the hopes of gaining something by it.
