Each man worthy of the part
Has a serpent in his heart,
Installed as on a throne, and who,
If he says: "I will" says: "No!"

Plunge into the eyes--so bright!--
Of satyress or Water-sprite,
The Tooth says: "Think of what is right!"

Beget a child or plant a tree,
Sculpt marble, polish poetry,
The Tooth says: "Will you outlive tonight?"

No matter what he hope or plan,
There is no moment left when man
Is not subject to the constant
Warnings of this odious serpent.
