The Key to Your Own Nativity

This book first appeared in 1911. Alan Leo himself described it as the most remarkable
book ever published. In his previous books Leo told us how to calculate and interpret
charts, with a distinctly Theosophical slant.
In this book, Leo (1860-1917), gives the prize secrets of the astrologer's craft. Among them, delineations for the Ruler of the Ascendant (aka chart ruler), including by sign and house. More broadly, he delineates each of the planets through the twelve houses in order to turn it about and delineate the rulers of those houses, based on the nature of the houses themselves: Finance (2), Travel (3), Environment (5), Enterprise (5), Sickness (6), Marriage and marriage prospects (7), Legacies (8), Philosophy (9), Profession (10), Friends (11), and the Occult (12). What do these houses in your chart say about you? Peek inside and find out!
Based on his lifetime's study, Leo gives succinct chart summaries. What life will be like if the majority of planets in your chart were in the East or West, above or below the
horizon, or the majority in fire, or air, or water, or earth signs, as well as cardinal, fixed or mutable. He gives special emphasis to the luminaries (Sun and Moon), delineating the pair of them both by element, as well as in all 144 possible combinations
of signs (polarities).
In every chart there is a rising planet. Leo delineates it. The Moon's sign at birth gives a distinct color to the aura. Leo will tell you what yours is. What will the future bring? Leo gives delineations for progressed planets, including the progressed
Moon by both sign and house. He concludes the book with a delineation for the King of England, George V.
In his life, Alan Leo reintroduced astrology to the western world, a phenomenal achievement.
