Astrological Houses' System

There are several methods to get the astrological houses , their principles , advantages and disadvantages , so that everyone can choose for themselves which system will adopt. Of the approximately 200 existing methods , and presented highlight : Campanus , Regiomontanus and Placidus .
The choice is given for two reasons : they are systems Houses Quadrants ( the Ascendant and Mid- Heaven correspond to the cusps of the houses I and X respectively ) and can be represented astronomically .
The criteria used to select and compare the methods are :
Consistency Astronomical : The method represents the local space time of birth of the native ?
Consistency astrology : The method fits the astrological principles laid down ? Allows derivative techniques ( Primary Directions ) ?
Interpretative coherence : Which language or information that are more appropriate to the method ?
The systems of houses and Wendell Koch - Page ( topocentric ) have astronomical representation , although quadrant houses systems , and therefore do not fulfill the first criterion.
Primary direction is a predictive method which relies entirely on astrological houses , and for this reason it is always used to validate a given house system . Based on the principle that observed with the Primary directions , at a given house system , we obtain the correct dates , so this method is reliable.
Therefore, the first two criteria are partly interchangeable , since the method that validates the second criterion relies heavily on concepts boosts.
The house system is a representation ... but of what?
This question was conceptually the minds of many astrologers and collides with another even greater problem , which is carrying a reference system for three-dimensional representation in two dimensions , such as a sheet of paper. Therefore , the difficulties are numerous.
So we need some initial concepts :
Each astrological house represents a sector or field of activity of human life , an area of action , with its particular symbolism due to its position in the zodiac , his ruler and the stars contained therein .
In the system of houses Quadrants , the Ascendant corresponds to the cusp of the house and I Half Heaven , the house cusp X. It is further considered that the cusps of the houses opposite also oppose ( lying in the same degree , the opposite sign ) .
To make the division that results the rest of the cusps , we have some possibilities , methods that result in major division of the houses :
Ecliptic (or zodiac ) : Once obtained the positions of the Ascendant ( and descending ) and the Mid- Heaven ( MC ) and Fund of heaven (CI ) , divides the region between the Ascendant and MC , the ecliptic , in three equal sections , obtaining the cusps houses XI and XII. Likewise , it proceeds dividing the ecliptic in the region between the IC and the ascendant in three equal regions for the house cusps II and III. Once the houses are opposed to each other , all other houses will be determined. Example : Method Porphyrio .
Time : Once obtained the positions of the Ascendant ( and descending ) and MC ( and IC ) , calculate the time the MC took the degree Ascending culminating . This value is divided by three , and projected from a reference system on the ecliptic , thereby obtaining the house cusps XI and XII. The same process is repeated for the MC to the descending degree being equally divided by three to arrive at the house cusps VIII and XI. Example : Placidus method .
Space : The Ascendant and MC are in the Local Sphere or Sphere Universal . Either are equally divided and projected on the ecliptic to obtain the other cusps . Example : Methods Campanus ( Local Sphere ) and Regiomontanus ( Universal Sphere ) .
In recent times , other astrologers have proposed different solutions for obtaining the house cusps , without resorting to methods of dividing up or relinquishing system Quadrant Homes .
The method of Campanus
Developed by the monk Giovanni Campani (1233-1296) , it is a system based on the Space Place . Basically rejected the idea of simply divide the ecliptic to get the house cusps , as was the method Alcabitius then in force .
Took as a reference the Prime Vertical , ( a circle that intersects the maximum points east and west of the Horizon , crossing even the Zenith and Nadir at right angles to the observer's meridian ) , which is divided into sections of 30 degrees each , with the poles the cardinal points north and south circles thus obtained intercetam the Ecliptic , resulting in the house cusps .

Método Campanus

The fact of taking the First Vertical reference for obtaining the cusps meet the criterion of consistency astronomical, as it represents faithfully the Local Space and divide properly.

Método Campanus II

Most critical to this system due to the fact of the ecliptic (or zodiac ) have secondary importance to focus on the Zenith and Horizon through the Prime Vertical . The ecliptic is the apparent path of the Sun and therefore argue that this method makes its symbolism ( the Sun ) is also placed in the background .
The Zodiac and the stars that are in heaven ( Universal Space ) are seen in this way , through the houses , placing the individual at the center of the whole space formed by the local and universal , but focused on first. For this reason , the method has been advocated by Dane Rudhyar and some other astrologers who postulated one Astrology centered on the individual . In fact , when we approached the house system of Campanus in more detail , we observe that the houses crossing the zodiac arcing and not exactly straight sections , as quoted by the Dane Rudhyar .
At this point , we can conclude that the second criterion is also valid , because the method Campanus fits the astrological principles provided to adequately represent each sector or field of activity of human life , absolutely centered on the individual , in a three-dimensional view .
As in most systems of astrological houses distortions also occur at high latitudes ( above 66 °) due to the obliquity of the ecliptic . Critics of this system argue that there is still a great distortion with stars of high latitude , as is the case of several stars . This is not a distortion of fact , once the homes represented in the ecliptic are a consequence of the projection that occurs from the Prime Vertical , and not from the Zodiac problem in most systems houses .
The method of Regiomontanus
Created a widespread belief that the Placidus system has become the standard used in the nineteenth and twentieth centuries to be the only one that had tables easy to use. But this is only partially true , because the same can be said of those made ​​by Regiomontanus . If Campanus also had, surely would have been the standard system of that period .
The person known as Regiomontanus was called Johann Müller and was born in Germany in 1463 , graduating as a mathematician and astronomer . With the assistance of Martin Bylica and find that there are shortcomings in the method of Campanus ( existing for nearly a century , but little used due to its complexity ) , Regiomontanus produced a set of tables from your own system .
Regiomontanus attended the team of astronomers and mathematicians who held the Julian calendar reform , the papacy of Sixtus IV , which resulted in the current Gregorian calendar. Their boards were the first houses to be printed regularly. His method has supplanted the Alcabitius , used throughout the Middle Ages.
In the system of Regiomontanus , the celestial equator is divided into arcs of 30 degrees from East Point ( EP ) , intercetando the North or South Poles The intersection of these circles with the ecliptic results in cusps astrological houses . It is therefore a system based on the universal space houses and rests partially in the local space (PE is obtained by the intersection of the first Vertical with Horizon ) .

Método Regiomontanus

In the diagram, the horizon is the great circle arc that divides the sphere into two. Where the Ecliptic interceta Horizonte is the Ascendant. The points on the equator are divisions of 30 degrees crossing the cardinal points North and South The cusps are projections from the Equator to the Ecliptic intercetam.
Also known as Rational System has been widely used by astrologers as Lilly, Cardan, Morin and Bacon. His method was only supplanted by the Placidus, and the system of standard homes for about 200 years.
This method is supported by astronomical. The ecliptic is not placed in the background as in Campanus, another point that favors this method. The fact that it is supported on Ecuador also allows easy correlation with time (longitude and time are interchangeable).
Although it represents perfectly the Universal Space, the same does not happen with the Space Place. Therefore, this method is not centered on the individual only includes the world (in the world). Distortion at high latitudes are smaller than those found by the method of Campanus, including the stars of high ecliptic latitude.
From an interpretive standpoint, the astrological houses represent sectors or fields of experience broader and less specific, portraying their relationship with the world.


The method of Placidus
From the nineteenth century, the tables Placidus houses become more affordable declining employment Regiomontanus houses, considered quite complex in its calculation and preparation.
This system takes the name of the Benedictine monk Placidus of Marmosets (1603-1668) who popularized its use during the seventeenth century.
As we have seen in previous systems, it is commonly accepted that Placidus did not create this method since this type of table was already available a year after its birth, and appeared around the year 1305. In the twelfth century, an astrologer Abraham Ibn Ezra Hebrew called himself known this method as employed by Ptolemy, but was Placidus who gave support, crediting the credit also to Ptolemy.
The system, Placidus houses is absolutely based on the time and says that is in harmony with the planetary hours.
Therefore, it is quite likely to be a system of old houses and maybe connected to that old system of counting time, associated with the passage of constellations by Zenith and Horizon, reinforcing the symbolism of the passage of the stars homes. Thus, each house represent two-hour diurnal motion of the Sun


It still seems that this was the house system used by Ptolemy in Primary Directions, and because of this, many astrologers end up defending this system. However, there is no evidence attesting to the veracity of this claim.
Anyway, the system Placidus houses is by far the most popular method in our own day. The boards Raphael Homes in greatly contribute to this popularity, although the "spirit" contained in the preparation of system houses should be equally respected.
Although the existing concepts in this method are quite simple, the calculation is by far the most complex because it is based on the projection of circles schedules, similar to Alcabitius and Koch. What differentiates one from the other method is the way to perform this projection.

Método Placidus

In the system of Placidus homes, homes cusps XI and III are points on the ecliptic obtained by semi-arches in a ratio of 1/3 of the distance meridian and house cusps XII and II, the ratio 2/3 . In other words, we can say that the cusps of the houses in the Placidus system correspond to points of the Ecliptic progressed, the ratio of 1/3 and 2/3 respectively, projected along their respective quadrants.
In case that the points of the ecliptic are no circumpolar obtaining the house cusps, which occur at latitudes that correspond to the complement of the obliquity of the ecliptic (about 23.5 degrees).
From an astronomical point of view, this method represents the partial Local Space will not be true, because it references itself primarily through Universal Space ecliptic, completing the second criterion, the consistency of astrology.
Distortion at high latitudes
When the latitude of the place to which you want to get the houses meet in the polar regions (from the circle of latitude 66.5 degrees), there will be problems in calculating the Ascendant and Mid-Heaven, from which the other homes are obtained.
In the Arctic and Antarctic polar circles, the ecliptic coincides with the horizon at certain times of the day. This implies that the Descending and Ascending can be anywhere (or none). Likewise, these occasions there will be Mid-Heaven or Fund of Heaven In this case, you can not get a house system, since these angles are needed for their calculation.


And even if the ecliptic does not exactly match the horizon, we are facing a critical situation because the slightest inaccuracy will lead to huge differences in the division of astrological houses.
If we take the example of a latitude of 66.5 degrees, we see that for a minute before the ecliptic coincides with the horizon, the second and fourth quadrants occupy slightly less than 20 'of arc. And two minutes, the same quadrants will occupy approximately 359.5 degrees.
Specifically in the polar regions, a part of the Zodiac never rises the horizon, implying that certain signs will never occupy the Ascendant. This situation occurs in certain areas of Norway, Alaska or Siberia, for example. In these regions, Sagittarius and Capricorn never rise in the horizon, while Gemini and Cancer never put. This means that the natives of these parts of the world will never have these Upward.
In extreme situations, the poles, the intersections of the zodiac with Horizon are in the same grade, which means that the signs of Aries to Virgo can be permanently above the horizon while their opposites are below. In this case, we have an Ascendant "stationary".


Querying a table of houses (quarters), we see that there is the same difficulty with respect to the Mid-Heaven.
We then conclude that the distortion at high latitudes is conceptual and stems from the way the Ascendant and Mid-Heaven are defined in System Quadrant Homes, and is not a particularity of either method.
However, in methods employing the semi-arches this distortion is more pronounced.
