英语寓言故事-The Herdsman and the Lost Bull

A HERDSMAN tending his flock in a forest lost a Bull-calf from
the fold.  After a long and fruitless search, he made a vow that,
if he could only discover the thief who had stolen the Calf, he
would offer a lamb in sacrifice to Hermes, Pan, and the Guardian
Deities of the forest.  Not long afterwards, as he ascended a
small hillock, he saw at its foot a Lion feeding on the Calf.
Terrified at the sight, he lifted his eyes and his hands to
heaven, and said:  "Just now I vowed to offer a lamb to the
Guardian Deities of the forest if I could only find out who had
robbed me; but now that I have discovered the thief, I would
willingly add a full-grown Bull to the Calf I have lost, if I may
only secure my own escape from him in safety."
