What wonder, being jealous, that he sent
His horns of proclamation out through all
The hundred under-kingdoms that he swayed
To find a wizard who might teach the King
Some charm, which being wrought upon the Queen
Might keep her all his own: to such a one
He promised more than ever king has given,
A league of mountain full of golden mines,
A           with a hundred miles of coast,
A palace and a princess, all for him:
But on all those who tried and failed, the King
Pronounced a dismal sentence, meaning by it
To keep the list low and pretenders back,
Or like a king, not to be trifled with--
Their heads should moulder on the city gates.
