The Origin of the Palace Separation System

The palace division system developed in the15th century, and has reached more than 50 kinds after years of research, among which 6 kinds are common, including Placidus, Koch, Regionmontanus, Campanus, Topocentric and Equal.

Placidus was founded by Italian monk Placidus de Titus in17th century, and it is quite popular in low latitudes. Koch is very popular in Germany and was invented by Dr. Walter Koch (1895- 1970). Kan Panouse's calculation method is close to the stereographic projection principle, which was advocated by Joseph and Matthew Kan Panouse in the15th century. The disadvantage of this system is that in high latitudes, the horoscope will be distorted so much that it can't be calculated. Reggiomontanus was invented by the German astronomer Reggiomontanus in the15th century, and the calculation result in equatorial region is the same as that in Panouse. Topological center is not a palace division system derived from mathematical methods, but is calculated by Argentine astrologers Andrew Polich and Anthony Nelson Page according to empirical statistics. The palace allocation calculated by Topocentric is quite close to Pacidus in many cases, but the calculation method is quite different from Pacidus. Equal palace system, divide the obtained 12 palace into 12 equal parts from Dongsheng point. Equality is a method used in ancient astrology. It is said that in Ptolemy era (AD 1 century), ancient Greek astrologers used the flat palace system. Generally speaking, astrologers will use Placidos, and Germany will use Koch. Fashion doesn't mean it's the best. What kind of palace division system is best? Everyone has his own preferences, and there is no uniform standard. The calculation method of the palace position division system is to calculate the belonging point and the science benefit (MC) according to the latitude and longitude of the birth time and place. Dongsheng point is the point where the horizon intersects with the ecliptic in the east of the birthplace at the moment of birth. Compared with the Dongsheng point, the intersection of the western horizon and the ecliptic is Dsc (Dscendant). These two points are connected to represent the horizon of birth. Above the horizon are the stars visible in the daytime, and below the horizon are the stars visible at night. Zenith is the highest point of the ecliptic in the celestial sphere at that time; Relative to the zenith, the lowest point of the ecliptic is the zenith (ic). After calculating the Dongsheng point, the celestial sphere at that time was divided into 12 parts according to the position of the Dongsheng point, and projected onto the ecliptic by projection method or other mathematical calculation methods, that is, the distribution of 12 houses on the altimeter.

The difference of palace division system lies in the different concepts and calculation methods of Houtiangong, but they are all located at Dongsheng point and zenith, so no matter which palace division system is used, Dongsheng point and zenith will not change. It is difficult to evaluate which palace division system is the most correct. No one has done research to distinguish clearly. Most astrologers imitate and adopt Pacidus or Koch. Some astrologers pursue the spirit of originality and carry forward the ancient Greek astrological tradition of using the equal sign. Some people adopt different palace separation systems according to different needs.

The zodiac sign of the day after tomorrow has its astrological significance, and it can often play a role in judgment. Ancient astrologers, for the zodiac signs of the day after tomorrow, paid attention not to the scope of the signs, but to the existence of the signs. The head of the palace is not the border of the palace, but the center of the palace This is why the four corners of the astrolabe are the first, fourth, seventh and tenth houses. Inferred from this concept, no matter whether the star obsidian falls in the same house or not, the star obsidian near the head of the palace will have a great influence on the house.

Other opinions about the palace are also worth remembering. When the head of the palace falls in the constellation, the constellation becomes a house. If the head of the third house is in Gemini, then the effective range of the third house is the whole Gemini, regardless of whether the head is at the head or tail of Gemini. This system of palace division is used in Indian astrology. After all, Indian astrology and western astrology are two different astrology systems and should not be confused.

Another problem with the palace division system is that the palace is unevenly distributed in the high-latitude astrolabe. The latitude and longitude of the place of birth will greatly affect the calculation of buying a house. Near the equator, the purchased houses are almost evenly distributed. When the latitude is extremely high, some houses in the astrolabe occupy two constellations, while some constellations contain the heads of two houses. For example, in Bill Gates' astrolabe, if Pacidus is used, the eleventh house is headed by Aries, which is completely contained in the eleventh house, and the second and third houses are headed by Leo at the same time; For example, when using Koch, the eleventh house is dominated by Taurus, and Aries is completely included in the tenth house. This problem will appear in all other systems except the flat palace system. Astrologers are very careful when judging the astrolabe.
