Mundane astrology, often referred to as political astrology, is a branch of astrology that focuses on the affairs of nations, states, and cities. It is concerned with politics, government, and the laws that govern these entities. This article examines the techniques and practices used in mundane astrology, highlighting how astrologers interpret celestial phenomena to make predictions about political events and the fate of nations.
Astrological Charts and Horoscopes
In mundane astrology,
the affairs of a nation are often judged from the horoscope set up at the time of its official inauguration or the birth chart of its leader. Astrologers also consider various celestial phenomena such as eclipses, lunations, great conjunctions, planetary stations, comets, and ingresses. These elements are used to interpret the potential outcomes and characteristics of a nation.
For example, the United States is thought to have an astrological chart based on July 4, 1776, the day the Declaration of Independence was signed. This date is considered the "birth" of the United States as a nation, and July 4 is celebrated as a major national holiday, symbolizing the country's "birthday." Such charts are used to analyze the nation's characteristics and predict future events.
Ptolemy's Contributions
The techniques of mundane astrology were discussed in detail by the Alexandrian astronomer Ptolemy in his work Tetrabiblos. Ptolemy outlined the principles of mundane astrology, emphasizing the importance of understanding the general temperament of a community before assessing individual birth charts. He argued that the circumstances of individual lives are influenced by the fate of their community.
Ptolemy's work includes an association between planets, zodiac signs, and the national characteristics of 73 nations. He identified three core principles of mundane astrology: the familiarity of fixed stars with countries attributed to the sign of their ecliptic rising, the use of the time of a city's founding to establish its characteristics, and the significance of the Sun, Moon, and chart angles in determining a nation's fate.
Historical Practices
The practice of mundane astrology has a rich history, with evidence of its use by English astrologer Richard Trewythian. Trewythian's notebooks, dating from 1430 to 1458, reveal his construction of horoscopes for the Sun's ingress into Aries and his predictions for various years. His work demonstrates the application of astrological logic to political events, such as wars and the health of the king.
Trewythian's predictions were based on planetary aspects and luminary applications, illustrating the practical use of mundane astrology in medieval England. His work highlights the enduring relevance of astrology in political decision-making and its role in shaping historical events.
