Two pyramids stand on the edge of a road; in front of them two dogs howl at the moon; below, a scorpion is seen. One of the pyramids is white and is the emblem of True Science; the other pyramid is black and is the symbol of Error. The two dogs represent Good and Evil, and the scorpion is the emblem of Perversity, the worst feature of vice.
This Arcane, XVIII., means that everything is conspiring against you and you alone are kept in ignorance of the real situation. Enemies of the worst kind are plotting against you, often hiding their treachery under the garb of flattery.
