In astrology, the Imum Coeli (IC; from Latin for "bottom of the sky") is the point in space where the ecliptic crosses the meridian in the north, exactly opposite the Midheaven. [1] It marks the fourth house cusp in most house systems (this is reversed in the southern hemisphere). [2]
The Imum Coeli is said to refer to people's roots and also to the least conscious part of the self. It symbolizes foundations, beginnings in life, what may have been experienced through parental inheritance and homeland influences, need for security and relationships with the home and family life. It also may describe the circumstances that someone will encounter at the end of their life. [3] Because this house was the most distant point possible from the visible part of the horoscope, Hellenistic astrologers considered the IC to be the home of the underworld, or Hades.
In many cases the IC refers to a parent—traditionally, the mother. [4] Modern astrologers may use the IC as a significator for the father, [4] or for both parents. There is no consensus in modern usage for which parent is best represented by the IC. The point is moot for Hellenistic astrologers who considered the fourth house the house of the father, but did not use the Imum Coeli as the cusp of the fourth house.
Using the natural houses system (see cadent houses) and modern quadrant house systems in which the IC is the cusp of the fourth house, some modern astrologers see a correspondence between the fourth house and the astrological sign Cancer. [5] However, traditional astrologers, using whole-sign houses, never made this connection.
In whole-sign house systems the signs and houses have the same boundaries; hence the Imum Coeli can actually appear in the third house, the fourth house or fifth house; in cases of extreme terrestrial latitude, it may even fall in the second or sixth houses. [6]
Astrology is a pseudoscience that claims to divine information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Many cultures have attached importance to astronomical events, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Arab world and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.
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 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.
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 the planets make to each other in the horoscope, also to the ascendant, midheaven, descendant, lower midheaven, and other points of astrological interest. Aspects are measured by the angular distance in degrees and minutes of ecliptic longitude between two points, as viewed from Earth. According to astrological tradition, they indicate the timing of transitions and developmental changes in the lives of people and affairs relative to the Earth.
The ascendant is the astrological sign that is ascending on the eastern horizon at the specific time and location of an event.
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.
Natal astrology, is a system of astrology that can help shed light on an individual’s personality or path in life. The concept is based on constructing a natal chart for the exact date, time, and location of that individual's birth. Natal astrology can be found in the Indian or Jyotisha, Chinese and Western astrological traditions.
The midheaven is a point of definition in the ecliptic coordinate system. It aims to find the part of the ecliptic that corresponds to the highest point in a celestial object's apparent daily traverse of the visible sky, midway between its ascension on the eastern horizon and descension on the western horizon. The midheaven does not represent the point immediately overhead or even the point of the ecliptic closest to it, but the point at which the local meridian intersects with the ecliptic.
In astrology, exaltation is one of the five essential dignities of a planet. The exaltation is a place of awareness for the planet, whereas the fall is a position of weakness concerning the function of the planet. The sign position directly opposite a planet's sign of exaltation is considered to be its fall.
In astrology a planet's domicile is the zodiac 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.
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.
In astrology, an angular house, or cardinal house, is one of four cardinal houses of the horoscope, which are the houses in which the angles of the chart are found. The angular houses of the horoscope are considered to be the most ardent, or forceful, and are considered to have the greatest impact in the chart. The influential 17th-century astrologer William Lilly states simply: "Planets in angles do more forcibly show their effects." Angular houses rule those critical things in our life, such as our appearance and how we behave, our family life, our married life or partnerships, and our career.
In astrology, a cadent house is the last house of each quadrant of the zodiac. A quadrant begins with an Angular house, proceeds to a Succedent house and ends with a Cadent house. There are four quadrants in an astrological chart, providing four Angular, four Succedent, and four Cadent houses.
In astrology, a triplicity is a group of three signs belonging to the same element.
The angles are the four Cardinal points of an astrological chart: the Ascendant, the Midheaven, the Descendant and the Imum Coeli.
Hellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek. The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era.
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.
Bhāva is a term in Jyotisha denoting a fixed zodiacal division of the sky from the perspective of an observer. It corresponds to the concept of "house" in Western astrology. A natal chart is called bhāvachakra
