Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE LION AND THE FROG
A lion heard a frog croaking loudly and turned towards the sound, thinking that
this must be the sound of some huge beast. After a while, the lion saw the frog
come up out of the swamp. He went over to the frog and as he crushed him underfoot,
the lion said, 'No one should be worried about a sound before the thing itself
has been examined.'
This fable is for a man with a big mouth who talks and talks without accomplishing
