Aqua astra (Abu Ali Al - Khayyat) theory of the whole star height (prosperity and adversity) contains the following methods

A month, day, day and night third ruler

Aqua astra from Greek spirit of astrology, emphasize the power of a picture plate root is associated with day and night, this is the most easy to detect human upon earth astronomical phenomenon: day and night change.Astrologers believe that Greece is dictated by the sun during the day time, night is dictated by the lunar time.

Therefore, when we get a picture plate, after the Greek astrologer told we must first understand the picture was born was born during the day or evening?To know this problem, only to watch the position of the sun on the chart can be learned.

When the sun fell on the ground plane, that is, from the 12th GongShun clockwise to the six house, the seventh house is born during the day.When the sun fell on the ground plane, which is the first palace counterclockwise to the sixth this six palace, was born at night.

The commonly used method in the middle ages after the "four quadrant palace method" (such as Alchabitius, Placidus...) is easy to understand, but if it is using the Greek tradition "the palace" (Whole - Sign House), will have error, must degree (Asc) and the order of the degree of the zodiac can correctly determine the sun falls on the first day and night, seven palace.

Secondly we must first understand what is three main (triplicity)?Three main records, the earliest for more than a century or so ambrosius AD's book, he mentioned three points in accordance with the four elements's star sign to differentiate,

Fire sign three points as follows: star MuTu

Wind three points for the star sign: soil shuimu

Water sign three points as follows: star month gold the fire

Earth sign three points as follows: star gold on fire

Refer to the appended drawings, such as more drag le dense puts forward three main, can know more ambrosius, using three main sequence for day and night, condominium.And drag of three points only two star, respectively in charge of the day and night.

Back to our topic, aqua astra tells us, to understand a picture of the whole star of high and low, you need to know it is a stranger, night and day, a stranger or a picture set during the day because the sun is dominated, and in the evening is lunar dominated, thus to view of lunar night and day, is born of the sun, why the sign, and in accordance with the days and designate three star constellation in which the month, day and night.

Designate three points in the main, must pay attention to the order of Bai Tiansheng order: day and night, condominium, night life order: night and day, condominium.

Day after day and month of three main, astrologers are in accordance with the three stars to understand the man at the end of the life of three phase of the basic life.In accordance with the aqua astra, three main xi in acquired strong house, and from the Angle of cut infortune.

Refers to the so-called strong palace: 1, 10, seven, four palace, the four strong palace called "Angle palace" (Angle), planets in Angle of house is strongest, followed by further palace (succedent) : 11, five, two, eight, if the planet is in fruit house is (cadent) : nine, three, six, twelve, it's unfavorable position, more difficult to benefit.

So-called infortune refers to: Saturn and Mars, relative to its fortunes: Jupiter, Venus, in addition, the general will be the sun, the moon as a assistant, mercury to neutral.

So-called crossing Angle, if by Greek astrological system, refers to the form with me: 60 degrees, ninety degrees, one hundred and twenty degrees, one hundred and eighty degrees of the house of the seven, and star telecom with palace is generally not known as a phase (Angle).This concept with the middle ages and modern astrology in crossing Angle are not the same.

Greek astrological crossing Angle is used throughout the house to theory, rather than the planet degree.Jupiter in Pisces octave, therefore Mars in cancer 20 degrees, according to the Greek astrology, fire wood is the relationship between each other have a triad of palace, but according to astrology or modern astrology, medieval, because of the large phase allows for fire wood does not form a triad crossing Angle.(The zodiac /astro/)

Suggestion is that if a planet of each other within the permissible degree, its effect is relatively strong and clear, if not of permissibility, but is still of palace, Yun within the effect is not obvious.If use the Greek astrological method, this paper to give priority to with Greek of palace, consider of the permissibility of intensity theory.
