Franciscus Kieser, Cabala chymica. Mühlhausen,
Johann & Martin Spies, 1606

Franciscus Kieser, a follower of Paracelsus, published a Paracelsist compendium in which he asserted that the highest secrets could not be attained without thorough experience of magic and Kabbalah: all those who had been in possession of the Philosophers' Stone had been magi and kabbalists, which could easily be proved.
