• "Toledo, I must needs confess and acknowledge that veritably the devils cannot be killed or die by the stroke of a sword, I do nevertheless avow and maintain, according to the doctrine of the said diabology, that they may suffer a solution of continuity (as if with thy shable thou shouldst cut athwart the flame of a burning fire, or the gross opacous exhalations of a thick and obscure smoke), and cry out like very devils at their sense and feeling of this dissolution, which in real deed I must aver and affirm is devilishly painful, smarting, and dolorous."
