it is not less absurd, then strange, to see how some Men… wil not forebeare to ranke True Magicians with Conjurors Necromancers, and Witches…who insolently intrude themselves into Magick, as if Swine should enter into a faire and delicate Garden, and, (being in League with the Devill) make use of his assistance in their workes, to counterfeit and corrupt the admirall wisdome of the Magi, betweene whom there is as large a difference as between Angels and Devils.
(Elias Ashmole : Theatrum Chemicum Britannicum. 1652, p.443.)
