Between the January 1589 and the spring of 1590, at Helmstedt, Giordano Bruno wrote "The Lulliana Medicine”. This work consists of a practical application of the Lullian System in the medical astrology. The text incorporate large sections of Explanatio Compendiosaque Applicatio Artis Illuminati Doctoris Magistri Raymundi Lulli (1235-1315), edited by the Franciscan Bernard de Lavinheta (c.1517). The work opens with the premise that health is determined by the balance of four elements, fire hot and dry, the air hot and humid, the water cold and wet and the earth dry and warm. Regarding the astrological studies applied to the medical art, Bruno gave to the world a vision of nature alive full of magic and spirituality.
