I am your father's spirit,
Doomed for a certain time to walk the night,
And during the day I am confined to burn in fires,
Until the evil crimes I had done in my life
Are burnt and purged away. If I were not forbidden
To tell the secrets of my prison house,
I could tell a tale whose lightest word
Would crush your soul, freeze your young blood,
Make your two eyes, like stars, jump from their sockets,
Your knotted and combined hair to separate,
And each particular hair to stand on end
Like quills on the angry porcupine.
But this eternal description must not be given
To ears of flesh and blood. Listen, listen, O, listen!
If you ever loved your dear father —
