How to see through the astrolabe

Astrolabe (Greek:? στρολ? β ν Astrobon' Star Picker' is an important astronomical instrument used by ancient astronomers, astrologers and navigators for astronomical measurement. It has a wide range of uses, including locating and predicting the positions of the sun, the moon, Venus and Mars-related celestial bodies in the universe, determining local time, latitude and longitude, triangulation and so on.

A birthday chart or a NatalHoroscope (hereinafter referred to as the astrolabe) is a star chart with the same arrangement position of the stars in the sky at the moment of your birth. Therefore, in order to discharge a correct astrolabe, we must first have an exact date, time and place of birth.

With the personal constellation after the time and place of birth, we can take conversion of time as standard time (GMT, Greenwich Mean Time) and find out the latitude and longitude of the place of birth. After completing this step, early astrologers had to compare these data with ephemeris, find out the exact position of each star, and then calculate the angular relationship between them one by one, but thanks to science and technology, there are many softwares that can do this work for them now.

Let's just say. The constellation seems to be a musical score. You are a performing singer. You can't call this a rubbish song just because you can't understand the meaning of the lyrics and can't sing well. Sometimes, a good singer can turn ordinary songs into natural sounds.

In this earth's magnetic field, you did choose this song, which cannot be changed. It depends on your singer. Music score is one of the expressions of songs, and it is the product of two dimensions, just like a constellation. Only used to describe your life, written because of songs. Similarly, it is because of you that this astrolabe was created.

Charts are used to describe and analyze you. It is your soul that chose to be born under such a starry sky, not the stars that deliberately arranged to disturb you. As for why your soul chose this way, we can't go further and further here. We can only explain it briefly. For example. Why do people choose to watch horror movies to scare themselves? Knowing that the movie is fake, I'm really scared. Why go to see it? Simple, to experience that feeling and taste. No way, perfection is actually boring, so God left the experience of imperfection to mankind.

Development of astrolabe

The earliest astrolabe was invented in ancient Greece around 200 BC. The earliest inventor is not recorded, and general historians generally believe that hipparchus is its inventor. This astrolabe can effectively solve many problems related to analog calculation in astronomical measurement. (Note: Evans (1998: 155) "The astrolabe is actually an invention of ancient Greece."

Krebs company. Krebs(2003:56) "Usually used by Greek astronomers, the astrolabe is a tool for measuring the height of the stars and the zodiac, which was invented in BC 1 century and the 2nd century. Some historians owe their invention to Hippak.

Astrologer: It is an ancient astrological computer that can solve the problem of time and tell the position of stars in the sky. Although it was invented by the ancient Greeks, the Islamic prophet was the first person to invent the portable astrolabe, which was a revolutionary astrological discovery.

Legendary inventors include Bruno Chase, Apollonius and others, but they lack sufficient evidence. The earliest record of the astrolabe may be Ptolemy's Motto, in which he used a whole section to describe the structure and usage of the astrolabe in detail. He didn't say clearly whether it was the creation of predecessors or his own invention. But the astrolabe structure he described has been very consistent with the physical objects seen by later generations.

The main body of the astrolabe consists of a disk surface and a copper ring. The upper gray ring is called "rete" (Latin Rete, from Arabic "Spider Web"), which can rotate on the lower disk with the north celestial pole axis. The pole is also centered on the north celestial pole and can rotate freely on the astrolabe plane. Using geometric projection method, the horizon coordinate network is projected onto the disk surface of the altimeter. Special attention should be paid to the determination of the position of the zenith in the horizon coordinate system-the angular distance between the zenith and the north celestial pole (or the position of the north celestial pole in the horizon coordinate system of the altimeter) changes with the change of local geographical latitude. In other words, any such astrolabe can only be used at a certain geographical latitude to obtain accurate data. Curved stars (some astrolabes are also made straight) are used to represent those special stars (such as stars that are particularly bright or have special astrological significance).

Although the astrolabe is not large and its structure is not too complicated, we have to admit that it is indeed a very clever instrument-it can be used for many purposes, such as:

1. Demonstrate the Sunday apparent motion of local stars. As long as the net ring is rotated, the sharp stars on the ring indicate the trajectories drawn by these stars in the local horizon coordinate network.

2. Determine the time. Hanging the altimeter vertically, first observing the horizon latitude of the sun; Then rotate the position of the sun on the ecliptic to the observed horizon latitude circle, so that the two intersect at one point; Then the line connecting this point with the north celestial pole is extended to the time circle with the datum, and its intersection point represents the observation time. When using this method, you can also use a star instead of the sun, so it can be implemented day and night.

Astral disk symbol

1, palace position

Let's look at the inner circle with Arabic numerals written on it. 1, 2, 3 ... There is a symbol next to each Arabic numeral. What does this mean?

Among them, 1, 2, 3 ... points to twelve sector areas with different sizes marked with numbers, which are called palaces. Similarly, the small symbol represents the ruler of the house. In the second paragraph of the text area on the right, the positions of various palace lords are listed. For example, 1 stands for Mars and 2 stands for Venus. ...

There are two straight lines through the astrolabe. The horizontal line runs through the horizon, and the longitude line goes from top to bottom. The east and west ends of the horizon, that is, the heads of the first and seventh houses, are called rising points and falling points respectively. The upper and lower ends of the meridian are the heads of the tenth and fourth houses, which are called zenith and nadir respectively. The constellation where the rising point is located is the so-called rising constellation. These planets and houses represent the zodiac and the afterheaven. What does the zodiac mean the day after tomorrow? This is the fifth chapter of this book' Twelve Mysteries of Fate' to tell you.

2. Stars

Now let's look at the innermost circle.

There are ten scattered star symbols just introduced, and each star is located in a different position. Stars are shown as marker points in the central region of the astrolabe. The third paragraph in the text area on the right lists the specific positions of the stars. For example, Jupiter is in Sagittarius and the moon is in Capricorn. What do these stars mean? The above is the content of the third chapter of this book,' Special Tiangong Map for Special You'.

The abbreviations of major stars are as follows:

Sun Sun Moon Moon Mercury Venus Mars

Jupiter Saturn Uranus Neptune Pluto
