Lisa Morpurgo Dordoni (Soncino (CR), 19 May 1923 - Milan, 9 May 1998) was a writer and astrologer.Lisa gained a degree in literature at the Università Statale di Milano.She started to be interested in astrology while working as a translator for book publishers.Lisa was first intrigued by astrology while translating the French book " Lo Zodiaco - Segreti e sortilegi " by François-Régis BastideThe translation of this book about zodiacal signs peculiarities awakened her curiosity for astrology, a matter up to that moment so distant from her cultural background. Thanks to her thorough study of this new form of knowledge she had been able to sketch the zodiacal map of some of her remarkable friends - mostly writers, such as Eugenio Montale, Dino Buzzati, Guido Piovene, Gabriel García Márquez, Mario Vargas Llosa - an interesting work that considerably improved her knowledge and urged her to unveil the reasons why zodiacal mechanisms seemed to effectively work.From this starting point on, an impressive amount of discoveries took place: she could no longer accept the obsolete and fideistic dogmas of traditional astrology. Therefore she set on the search for those astrological mechanisms – based both on observation and science - which lay under each phenomenon. Her unprecedented practice meant a real revolution in astrology as it had been considered up to that time and opened new roads to research, applied with seriousness and thoughtness. She was the starter of a new current of thought both through her lessons and her books, the real milestone for astrologers and for those interested in the zodiac.In 1968 Lisa published her first novel, Madame andata e ritorno. In 1972 she published her first astrological book Introduzione all'astrologia e decifrazione dello Zodiaco, a real milestone for zodiac knowledge, that reached tens further editions, as a long seller, in several countries.In 1975 she published Macbarath, a science-fiction novel which anticipated her future astrological discoveries.In 1979 she published what was defined her most important astrological book Il convitato di pietra.In 1988 she published her fourth novel : La noia di Priapo. Between 1983 and 1992 she published Lezioni di Astrologia in order to further her astrological theories: La natura dei segni, La natura dei pianeti, La natura delle case, La natura dei transiti.Among other books, she wrote L'astrologia e l'amore and Bimbo astrologo.In her theories Lisa applied a logical and rational approach to astrology.She revisited astrological theories reconfiguring the system of domiciles and exaltations of the planets.This approach gave more value to astrological theories which suggested the existence of two more planets.Lisa defined them as X-Demetra and Y-Eolo. X would signify the great female principal, in complementary opposition to the meaning of Pluto.Y would signify the great ruler of long and slow time and low frequencies - lord of meteorological and geological phenomena, in complementary opposition to the meaning of Neptune.Lisa organised and directed 12 congresses of astrological studies.The first one in Laveno in 1976, others in Ferrara, Varese, Mantova, Verona, Riccione, the last one in 1993.The main characteristic of Lisa's work was the attempt to link empirical observation to zodiacal symbology with the objective of denying or confirming astrological traditional beliefs and suppositions by means of rational observation of phenomena.In a few words, we can say that Lisa Morpurgo achieved the complete zodiac deciphering on the basis of strict logical and geometrical principles, identifying all its components. But she was particularly brilliant at deciphering what was hidden inside that heavenly mechanism: the interpretation code of cosmic reality that, through two different zodiacal systems A and B (each with its two specific Zodiacs), completes the map of the real Cosmogony.
