little is known, might thus have been a kind of Rosicrucian. For since, as has been said, the intellectual chiefs from whom the poisoners derived their inspiration were men versed in chemistry, in science, in physics, and the treatment of diseases, and since, further, they included alchemists and people professing to be in possession of the Philosopher's Stone, their resemblance with the Rosicrucians is at once apparent. Indeed, in turning back to the branches of magic enumerated by the Rosicrucian Robert Fludd, we find not only Natural Magic, "that most occult and secret department of physics by which the mystical properties of natural substances are extracted," but also Venefic Magic, which "is familiar with potions, philtres, and with various preparations of poisons."
The art of poisoning was therefore known to the Rosicrucians, and, although there is no reason to suppose it was ever practised by the heads of the Fraternity, it is possible that the inspirers of the poisoners may have been perverted Rosicrucians, that is to say, students of those portions of the Cabala relating to magic both of the necromantic and venefic varieties, who turned the scientific knowledge which the Fraternity of the Rosy Cross used for healing to a precisely opposite and deadly purpose. This would explain the fact that contemporaries like the author of the Examination of the Unknown and Novel Cabala of the Brethren of the Rose-Cross should identify these brethren with the magicians and believe them to be guilty of practices deriving from the same source as Rosicrucian knowledge--the Cabala of the
