Branches of Horoscopic Astrology
Traditions of horoscopic astrology can be divided into four branches which are directed towards specific subjects or purposes.
Often these branches use a unique set of techniques or a different application of the core principles of the system to a different area. Many other subsets and applications of astrology are derived from these four fundamental branches.
Natal astrology is the study of a person's natal chart to gain information about the individual and his/her life experience. Katarchic astrology includes both electional and event astrology.
The former uses astrology to determine the most auspicious moment to begin an enterprise or undertaking, and the latter to understand everything about an event from the time at which it took place.
Horary astrology is used to answer a specific question by studying the chart of the moment the question is posed to an astrologer. Mundane or world astrology is the application of astrology to world events, including weather, earthquakes, and the rise and fall of empires or religions.
This includes the Astrological Ages, such as the Age of Aquarius, Age of Pisces and so on. Each age is about 2,150 years in length and many people believe these massive ages correspond to major historical events and current developments in the world.
