- n. The doctrine of the devil; diabolical lore: as, the diabology of Milton's “Paradise Lost.”
Sorry, no etymologies found.
Dr. Oliver Wendell Holmes even called the old theology largely "diabology."
Remember the theology and the diabology of the time.
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.
