An Ass, being driven along a high road, suddenly started off
and bolted to the brink of a deep precipice. While he was in
the act of throwing himself over, his owner seized him by the
tail, endeavoring to pull him back.
When the Ass persisted in his effort, the man let him go and
said, "Conquer, but conquer to your cost."
(Translated by George Fyler Townsend, 1814-1900)
