Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE SNAKE AND THE THORN BUSH
There was a grapevine next to a river, and a thorn bush had been planted as
a fence around the vine. When the river rose, the thorn bush was swept away
by the water, and a snake who had entwined himself in the thorns was also carried
away. When someone saw the snake riding on the thorn bush, he said, 'A wicked
ship, and worthy of its sailor!'
The story shows that a wicked person deservedly comes to a bad end by keeping
company with other wicked people.
