Forced them into a core of fire
Like the glede of a covetous desire,
Shut them fast in the heart of a stone.
And hard, and harder than the sword,
They made the crystal, fiery-cored;
On steel that oft had steel withstood
Might it grave the word it would.
A gem of beauty and of bale,
A prisoned force in narrow pale,
Evil-perfect, pure of good!
