In the 16th century a man widely known as Paracelsus proclaimed that the sylphs were small aerial beings that lived in a place called Fairyland.
Paracelsus also dubbed the sylphs as the "highest of the elementals, their vehicle is the wind."
All these physical theories are blended with a mystical theosophy, of which the most remarkable example is, perhaps, the chemico-astrological speculations of Paracelsus (1493-1541).
Of the followers of Paracelsus some became mere mystical quacks and impostors.
SYLPH, an imaginary spirit of the air; according to Paracelsus, the first modern writer who uses the word, an air-elemental, coming between material and immaterial beings.
The medicine of the 17th century was especially distinguished by the rise of sytems; and we must first speak of an eccentric genius who endeavoured to construct a system for himself, as original and opposed to tradition as that of Paracelsus.
Hahnemann (1753-1844) was in conception as revolutionary a reformer of medicine as Paracelsus.
Paris was the stronghold of conservatism, and Germany was stirred by the teachings of one who must be considered apart from all schools - Paracelsus.
He published several pieces bearing on medicine, astrology and alchemy, and attacking the system of Paracelsus.
The chief immediate result we can trace is the introduction of certain mineral remedies, especially antimony, the use of which became a kind of badge of the disciples of Paracelsus.
