on the revolutions of the heavenly spheres

We had built pyramids, great walls, explored the world and moved away from the idea of a flat Earth (good news for all those sailors on long voyages – no risk of falling off the edge). Human civilization was already over 5000 years old by the times of Copernicus (1473-1543). Photo and copyright Nuwanthika Fernando ©, all rights reserved. First edition print of Nicolaus Copernicus’s ‘On the Revolutions of Heavenly Spheres’. Its age is not the only reason why it’s so valuable – this is where he introduced the ‘heliocentric’ model of the solar system, where the Earth is taken out of the centre of the solar system to be replaced with the Sun. The carefully preserved first edition print of Nicolaus Copernicus’ ‘On the Revolutions of Heavenly Spheres’ is 473 years old and valued at just over US$1 million. It is suitable for both beginners and advanced students, as it provides the indispensable core of astrological knowledge, at the same time allowing more experienced students to organize their knowledge into a coherent system.Nuwanthika Fernando is an astronomy guide at Sydney Observatory, and studies the dynamics of satellite galaxy planes for her PhD at the University of Sydney.ĭuring a recent conference visit to the Astronomical Observatory of Capodimonte in Naples, Italy, I was lucky enough to catch a glimpse of a book that created a true paradigm shift in the way we think. This practical how-to book is one of a kind, and the one that will teach you the traditional methods and you reach into the past to benefit from the knowledge of the authors and astrologers from ancient Babylonia through the medieval period. In addition, more than two hundred fifty illustrations make the traditional principles easy to understand and use in chart interpretation. It avoids cookbook-type methods and centers on the practical understanding of the astrological concepts, presenting the Tradition in present-day language. Their method is the traditional and time-honored one, and includes, among others, chapters on: The Planets The Zodiac and the Signs The Essential Dignities The Houses The Aspects Chart Dynamics The Condition of the Planets The Fixed Stars The Parts The Power of the Planets Using this traditional method, it is possible not only to thoroughly and completely read the natal chart but to do so with a breadth and depth of meaning not found in the modern methods of astrological interpretation. The rules and principles here presented apply to all branches of astrology,natal, mundane, horary and elective. It is out of this tradition that Helena Avelar and Luis Ribeiro have written this extensive book on astrology. For most of these millennia, astrologers used only the seven visible planets: Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn. Out of these early observations and subsequent refinements came what today is known as astrology. Thousands of years ago, people first observed a correlation between the heavenly bodies and events on Earth.
