Mormius, Peter (17th c.) Alchemist and Rosicrucian. In 1630 Peter Mormius, a noted alchemist and author of Rosicrucian works, sought to introduce Rosicrucianism into Holland by petitioned the States-General for a public audience. Mormius said that he had a plan to make Holland the richest and happiest nation on Earth with the help of the Philosopher's Stone and Elementary Spirits. Unimpressed, state officials turned him away. Mormius then thought that he could force this issue by publishing his alchemical book which he did during the same year in Leyden. The Book of the Most Hidden Secrets of Nature was comprised of three parts: perpetual motion, transmutation of metals, and universal medicine. This failed as well.
