As on the road he moved, a clown he met,
Who with his stick an adder tried to get,
From out a thicket, where it hissing lay,
And hoped to drive the countryman away:
Our knight his object asked; the clown replied,
To slay the reptile anxiously I tried;
          met, an adder I would kill:
The race should be extinct if I'd my will.
