The zodiac is a belt-shaped region of the sky that extends approximately 8° north and south of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. Also within this zodiac belt appear the Moon and the brightest planets, along their orbital planes. The zodiac is divided along the ecliptic into 12 equal parts ("signs"), each occupying 30° of celestial longitude. These signs roughly correspond to the astronomical constellations with the following modern names: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
A horoscope is an astrological chart or diagram representing the positions of the Sun, Moon, planets, astrological aspects and sensitive angles at the time of an event, such as the moment of a person's birth. The word horoscope is derived from the Greek words ōra and scopos meaning "time" and "observer". It is claimed by proponents of astrology that a horoscope can be used as a method of divination regarding events relating to the point in time it represents, and it forms the basis of the horoscopic traditions of astrology, although practices surrounding astrology have been recognized as pseudoscientific since the 18th century. Horoscope columns are often featured in print and online newspapers.
Western astrology is the system of astrology most popular in Western countries. Western astrology is historically based on Ptolemy's Tetrabiblos, which in turn was a continuation of Hellenistic and ultimately Babylonian traditions.
Most horoscopic traditions of astrology systems divide the horoscope into a number of houses whose positions depend on time and location rather than on date. In Hindu astrological tradition these are known as Bhāvas. The houses of the horoscope represent different fields of experience wherein the energies of the signs and planets operate—described in terms of physical surroundings as well as personal life experiences.
In astrology, an aspect is an angle that planets make to each other in the horoscope; as well as to the Ascendant, Midheaven, Descendant, Lower Midheaven, and other points of astrological interest. As viewed from Earth, aspects are measured by the angular distance in degrees and minutes of ecliptic longitude between two points. According to astrological tradition, they indicate the timing of transitions and developmental changes in the lives of people and affairs relative to the Earth.
Hindu astrology, also called Indian astrology, Jyotisha and, more recently, Vedic astrology, is the traditional Hindu system of astrology. It is one of the six auxiliary disciplines in Hinduism that is connected with the study of the Vedas.
Horary astrology is an ancient branch of horoscopic astrology in which an astrologer attempts to answer a question by constructing a horoscope for the exact time at which the question was received and understood by the astrologer.
The Age of Aquarius, in astrology, is either the current or forthcoming astrological age, depending on the method of calculation. Astrologers maintain that an astrological age is a product of the Earth's slow precessional rotation and lasts for 2,160 years, on average.
Astrology and astronomy were archaically treated together, but gradually distinguished through the Late Middle Ages into the Age of Reason. Developments in 17th century philosophy resulted in astrology and astronomy operating as independent pursuits by the 18th century.
An astrological age is a time period which, according to astrology, parallels major changes in the development of human society, culture, history, and politics. There are twelve astrological ages corresponding to the twelve zodiacal signs in western astrology. One cycle of the twelve astrological ages is called a Great Year, comprising 25,772 solar years, at the end of which another cycle begins.
Mundane astrology, also known as political astrology, is the branch of astrology dealing with politics, the government, and the laws governing a particular nation, state, or city. The name derives name from the Latin term mundus, 'world'.
Essential dignity, in the context of an astrological horoscope or natal chart, refers to the relative “strength” or “weakness” of a planet based on its zodiac sign and specific degree. This strength or weakness is referred to as the planet’s essence—what the 17th-century astrologer William Lilly called "the strength, fortitude or debility of the Planets [or] significators."
In astrology, a planet's domicile is the zodiacal sign over which it has rulership. This is a separate concept from the houses of the horoscope. A planetary ruler is given to each sign, over which the planet is said to have a more powerful influence when positioned therein. The ruling planet associated with a sign is also used as an implied focus of interpretation for the signs on house cusps in a chart. A planet is considered to be in domal dignity when it is positioned in the sign it rules. This is the strongest of the five essential dignities of a planet. Domicile is an archaic term in infrequent, specialist uses today; most astrologers use the simpler term "sign".
In astrology, accidental dignity occurs when a planet gains strength for any reason other than its zodiacal position. Accidental dignity should not be confused with essential dignity which is where a planet gains strength from its position in the zodiac. To understand the difference between accidental dignity and essential dignity, think of essential dignity as being relevant to the 'nature' of the planet and accidental dignity as relevant to how that planet 'finds itself', or its 'power to act'. As an example, in a horary question, the significator for a lost valuable ring may have good essential dignity, but may have little accidental dignity.
Tetrabiblos, also known as Apotelesmatiká and in Latin as Quadripartitum, is a text on the philosophy and practice of astrology, written by the Alexandrian scholar Claudius Ptolemy in Koine Greek during the 2nd century AD.
Jean-Baptiste Morin, also known by the Latinized name as Morinus, was a French mathematician, astrologer, and astronomer.
In astrology, certain stars are considered significant. Historically, all of the various heavenly bodies considered by astrologers were considered "stars", whether they were stars, planets, other stellar phenomena like novas and supernovas, or other solar system phenomena like comets and meteors.
Locational astrology is any of various types of astrology that factor in specific locations of the Earth. The different types also carry a range of astrological techniques.
In astrology, planets have a meaning different from the astronomical understanding of what a planet is. Before the age of telescopes, the night sky was thought to consist of two similar components: fixed stars, which remained motionless in relation to each other, and moving objects/"wandering stars", which moved relative to the fixed stars over the course of the year(s).
Christian Astrology, written in 1647 by the English astrologer William Lilly, is considered a seminal work of Western astrology. William Lilly successively treats the rules of western astrology, horary astrology and 'nativities', about erecting and analysing a birth chart in natal astrology. He wrote the book when he was ill and had to stay at home. Running away from the plague in London, he spent a year in the countryside to study, reflect, and write Christian Astrology.
