Quote :

"the nature of them (spirits of Saturday) is to sow discords, hatred, evil thoughts and cogitations, to give leave to kill and murder, and to lame or maim every member."

"Those spirits who appear in a kingly form, have a much higher dignity than them who take an inferior shape; and those who appear in a human shape, exceed in authority and power them that come as animals; and again, these latter surpass in dignity them who appear as trees or instruments, and the like: so that you are to judge of the power, government, and authority of spirits by their assuming a more noble and dignified apparition."
