Idea of revolution

I was permitted to sit, I felt that my senses were leaving me. The sentence, the dread sentence of death, was the last of distinct accentuation which reached my ears. After that, the sound of the inquisitorial voices seemed merged in one dreamy indeterminate hum. It conveyed to my soul the idea of revolution, perhaps from its association in fancy with the burr of a mill-wheel. This only for a brief period, for presently I heard no more. Yet, for a while, I saw, but with how terrible an exaggeration! I saw the lips of the black-robed judges.
