What are the regions corresponding to the twenty-eight constellations?

The twenty-eight constellations are divided into four groups according to the four directions of northeast, southwest, and each group of seven constellations matches four colors and five groups of animal images, called four elephants or four continents. The corresponding relationships are as follows: The eastern Canglong is cyan; the northern Xuanwu is black; the western white tiger is white; the southern red bird is red. The Seven Constellations of the East

1 Dongguan Qinglong

The Seven Constellations of the East include: Jiao, Kang, Di, Fang, Heart, Tail and Ji.

The horn is the dragon's horn. In the modern constellation organization system, Spica belongs to the constellation Virgo. The brighter Spica and Spica are first-magnitude and third-magnitude stars respectively. Modern times call them Virgo alpha and Virgo zeta. The ecliptic passes between these two stars, so the sun, moon and planets often pass near these two stars. This is why ancient books call the two stars Tianguan or Tianmen.

Kang is the dragon's throat. "Erya Shiniao" says: "Kang, bird's throat", annotation: "Kang means swallowing, commonly known as shouting." Kang constellation also belongs to Virgo, but it is smaller than Spica, and the stars in it are also fainter, mostly four. Wait for the following. In late April in Nanjing area, Virgo is in mid-air in the southeast around 9 p.m.

Di, "Shuowen": "Di, Zhiye; Congshi, with -, -, ground.". "Erya Shitian": "The root of the sky is Di." Note: "The horns are tied to Di, just like a tree with roots." Therefore, Di can be understood as the front legs of a dragon. The star belongs to the constellation Libra. Among them, the star γ is Libra, the star γ is Libra, and the star 1 is α Libra. They are all brighter stars of the second to third magnitude. These three stars form An isosceles triangle is formed, with Aldehyde at the vertex falling on the ecliptic.

The chamber is the chest chamber. "Historical Records of Heavenly Officials": "The house is the mansion, and it is also the Tiansi." The mansion is connected to the fu organs. "Erya Shitian": "Heavenly Si, Fang also." Note: "The dragon is Tianma, so the four stars of Fang are called Tiansi." Fangsu belongs to Scorpio, and the four stars of Fang are the heads of scorpions. They are both two , a brighter star of third magnitude (Scorpius beta, delta, pi, rho).

The heart is the heart of a dragon. The heart star, the famous Antares (Scorpio alpha), was called fire, fire, or business star in ancient times. It is a red giant star, red in color, and a first-magnitude star. Antares also belongs to Scorpio, and the three stars of Antares form the body of the scorpion.

The tail is the tail of the dragon. "Zuo Zhuan": "The nursery rhyme goes, 'In the morning of Bing, the dragon's tail lies in the morning'". The note says: "The tail of the dragon is also the tail star. The meeting of the sun and the moon is called Chen." , the sun is at the end, so the tail star is invisible. "Osu also belongs to the constellation Scorpio, which is the tail of the scorpion. It is composed of eight or nine brighter stars, among which the Scorpio lambda at the tip of the scorpion's tail is brighter than the second magnitude.

The dustpan, as the name suggests, looks like a dustpan. "Shi Xiaoya": "There is a dustpan in Weinan, which cannot be winnowed." It refers to it. Jisu belongs to the constellation Sagittarius, and the four stars of Jisu (Sagittarius gamma, delta, epsilon, eta) form a quadrilateral, shaped like a dustpan. In the Nanjing area, the above Di Fang Xin Wei Ji Wu Su appeared one after another in the mid-air in the south in the early morning.

2 Xiguan White Tiger

The Western Seven Constellations include: Kui, Lou, Wei, Pleiades, Bi, Shen, and Xiang.

Kui, "Shuowen": "Between the two thighs", "Guangya": "The crotch, Kui." Kui constellates the sixteen stars, and the left and right halves are just like the shape of the two thighs. "Bu Tian Ge" describes Kui Su as: "The waist is as thin as a broken shoe, and the tip of the head is like a broken shoe, and sixteen stars are born around the shoe." Kui Su 1 to 9 belong to Andromeda, and Kui Su 10 to 16 belong to Pisces. Most of these sixteen stars are dark stars of fourth or fifth magnitude, among which the brightest Kuisujiu (Fairy beta) is a second-magnitude star. Above Kuisuqi (that is, near the toe of Kuisu's shoe) there is a bright spot of about fourth magnitude, which is the famous Andromeda Nebula (M31).

Lou, Tonghu. Hu, "Shuowen": "Yijuye", "Jiyun": "Yiye, commonly known as Lou", "Gongyang": "cow and horse Weilou", annotation: "Tie the horse and say Wei, tie the cow and say "Lou." "Historical Records of Tianguan": "Lou is for gathering people." In ancient astronomical classics, Lou Su is regarded as a place in charge of pastoral sacrifices or gathering troops. The three stars belong to the constellation Aries (Aries alpha, beta, gamma), and the brightest star among them is the second-magnitude star. Lousu is located near the intersection of the ecliptic (the path of the moon) and the ecliptic.

Stomach, "Explanation of Names": "Stomach, surrounding, surrounding food." "Historical Records of Tianguan Shu": "The stomach is the warehouse." The three stars of the stomach belong to Aries (Aries delta, zeta, 63), are all small stars of fourth and fifth magnitude.

Pleiades, "Historical Records of Heavenly Officials": "Pleiades is called Maotou", Mao, "Shuowen": "Faye". Pleiades are also called Liu, which means clustering and grouping. For example, fruits with many seeds and clusters are called pomegranates, and fruits caused by the accumulation of diseased blood are called tumors. The Pleiades is composed of a group of small stars. People with good eyesight can distinguish seven stars. They are called the "Seven Sisters (Pleiades)" in Greek mythology. The ancients used Pleiades to determine the four seasons. "Yao Dian" of Shangshu states: "The short sun and Pleiades mark the middle of winter." This means that if you see Pleiades appearing in the mid-heaven at sunset, you can know that the winter solstice has arrived. The Pleiades belong to the constellation Taurus and are made up of a cluster of small stars.

Bi, "Rituals": "The clan members hold Bi first and enter first", and the note says: "The shape of Bi is like Yi". "Poetry Xiaoya": "There is Bi Tianbi", Zhu Xi's note: "The Bi sky is also the Bi star, which looks like Bi covering a rabbit." Aldebaran belongs to the constellation Taurus. Its shape is like a small fork, and it also looks like the English letter Y. "Song of the West": "The stars of Aldebaran are like a small net, and a pearl in the left corner shines brightly." The bright star in the left corner is Aldebaran (Taurus alpha), a first-magnitude star. "Historical Records of the Heavenly Officials" says: "The space between the Pleiades and the Pleiades is the Heavenly Street", which means that the sun, moon and planets often pass through here, and Mercury is currently located between these two stars. "The Book of Songs" says: "When the moon leaves at the end of the day, the waves are pouring." It refers to the onset of the rainy season when the moon passes through Biju.

Rigel and Rigel are called Orions in the West, and these two names are well-known at home and abroad. "Xibu Tiange": "Rigel is a bright candle at night, two shoulders, two feet and three are waists." This shows how eye-catching Rigel is in the night sky. From winter to early summer, Rigel is the most prominent constellation in the night sky. Rigel 1, 2, and 3 (Orion delta, epsilon, zeta) make up the hunter's belt. "Tang Feng": "Three stars, ginseng." Shen is a pictographic writing, which symbolizes the three stars of the belt. "Zuo Zhuan" uploaded: "In the past, the Gaoxin family had two sons. The uncle was called Yan Bo and Ji was called Shi Shen. They lived in the open forest and could not get along with each other. They often fought with each other to conquer each other. The later emperor did not know Zang and moved to Yan Bo. Shangqiu is the main star. Therefore, Chen is the star of Shang. "Chen is the star of Antares. The right ascension of Rigel and Antares is about 180 degrees different. People in the same place." They cannot be seen at the same time, so there is a folk saying that "participating in business does not meet each other". Betelgeuse (Orion alpha) is the hunter's right shoulder, Rigel (Orion gamma) is the left shoulder, Rigel (Orion kappa) is the right foot, and Rigel (Orion beta) is the left foot. They are all bright stars.

Above the shoulders, the shape can be associated with the horn-like beak, hence the name.

Edit this paragraph The Seven Constellations in the North

3 Beiguan Xuanwu

The Seven Constellations in the North include: Dou, Ox, Female, Virtual, Danger, Room, and Wall.

Dou, also known as Nandou. Like the Big Dipper, the South Dipper also looks like a dipper in the sky, hence the name. However, the scope and brightness of the South Dipper are inferior to those of the Big Dipper. Douban and Jisu among the seven Eastern constellations belong to the Sagittarius constellation, and the ecliptic passes between Douban (the Sagittarius lambda) and Douban (the Sagittarius mu). The winter solstice is currently located five degrees to the right of the midpoint between these two stars.

Cows were called morning oxen in ancient times; women were called Wu Nu or Xu Nu in ancient times. It is said that the names of Niu and Nu are derived from the two stars Cowherd and Weaver. The morning glory in the ancient poem "Far Altair Star, Bright River Han Girl" refers to the three stars of the river drum (the two river drums are the Cowherd). In 1978, the tomb of Marquis Yi of Zeng in the early Warring States period was excavated in Suixian County, Hubei Province. Among the unearthed cultural relics was a lacquer box. The lid of the box had the names of the twenty-eight constellations written in seal script. Among them, the two constellations of cow and female were written as Morning Glory and Wu Nu. It can be seen that The names of these two stars have a long history and are not necessarily derived from the two stars Cowherd and Weaver Girl. Ox and female are both inconspicuous constellations. Among the stars, Taurus

(Capricorn beta) and Taurus (Capricorn alpha) are third-magnitude stars, and the rest are fifth- and sixth-magnitude stars.

Among the female stars, only the brightest one (epsilon) is a fourth-magnitude star. By making an imaginary line from Weaver Girl to Cowherd and extending the distance by about double, you can find Niu Su. The Altar One is located to the left of the Taurus star. In Nanjing in early May, these two constellations can be found in the mid-air in the south before sunrise. "The Book of Rites and the Moon Order" says: "The month of Mengxia... Dan Wu Nu Zhong." This means that if you see the position of Nu Nu in the south at dawn, you will know that early summer is coming.

Xu, "Shuowen": "Qiu called it Xu." Ancient cities were often inhabited by Qiu. After the destruction of the city, Qiu was renamed as a ruin. Xu is located in the center of Beiguan. "Erya Shitian" says: "Xuan'er is Xu." Note: "Xu is in the true north, and the color of the north is black. The word "Xu" means "waste", and "loss" is also the meaning of "xu". Therefore, "Xu" has great meaning. Qiu means old place and waste. The Xu constellation has been quite famous in ancient times. The Xu constellation was recorded in the Sizhong Zhongxing in the "Shangshu Yaodian" written in the Zhou Dynasty. Appears at Midheaven in the south in the evening before and after. Make an imaginary line from Taurus to Taurus and extend it about one and a half times. The third-magnitude star encountered is Alpinia, which also belongs to Aquarius (beta Aquarius). Above the constellation is a fourth-magnitude star, belonging to the constellation Equus (alpha pony).

Danger means above the house. "Historical Records Suoyin" quotes "Book of Rites" as saying: "The middle house is in danger, so build a raised house to avoid soldiers." "Historical Records of Tianguan Shu": "Danger means building a house." "Jin Shu Tianwen Zhi": "Danger is the reason for building a house." Three stars, the main star of Tianfu City. "The three stars of Weisu include Alpha, Theta and Epsilon, all of which are second and third magnitude stars. The shape of this three-star star is like a pointed roof.

The room and the wall are two connected rooms. In ancient times, there was a camp room, also known as the east wall. The camp originally had four stars in a square shape, with two stars on the east wall and two stars on the west wall, just like a palace.

"Zi Ren, Official of the Zhou Dynasty": "Turtles and snakes roam around like a camp room." Then the east wall separated from the camp room and became a room with two walls. The lid of the lacquer box on the tomb of Marquis Yi of Zeng calls these two places Xiying and Dongying. The four stars on the east wall and the west wall are the famous Pegasus quadrilateral. Murojuku 1 (Pegasus alpha) and Murojuku 2 (Pegasus beta) are the west wall, also known as Ding. "Poetry?#123;Feng": "Dingzhifangzhong was created in the Chu Palace." During the Spring and Autumn Period, Murojuku was in The evening in late autumn and early winter appears in the south. This is the slack season for farming. People use this time to build houses to prepare for winter, so they are called barracks. Aldea (Gamma Pegasus) and Aldea (Fairy Alpha) are on the east wall. The right ascension of these two stars is very close to 0 degrees. If you connect a line from Aldea to Aldea and extend it approximately twice, you can Find the approximate location of the current vernal equinox.

Edit this paragraph The Seven Southern Constellations

4 Nanguan Suzaku

The Seven Southern Constellations include: Well, Ghost, Willow, Star, Zhang, Yi, and Zhen.

Well, "Historical Records and Tianguan Shu": "East Well is about water." The shape of the eight stars in the well is like a water well, hence the name. Jingsu belongs to the constellation Gemini, and the brightest one is Jingsu (Gemini gamma), which is a second-magnitude star. Pollux forms an isosceles triangle with Castor and Pollux (the twins alpha and beta). Wells is located between Pollux and Rigel. This is one way to find Wells.

Ghost, also known as ghost. Yu, "Ji Yun": "Zhongye", so Yugui can be understood as the meaning of all ghosts; "Shuowen": "Yu, the bottom of a car", the four stars of Guisu are in a square shape, like a car, this may be another symbol One layer of meaning. "Bu Tian Ge": "The four-star book is square like a wooden cabinet, and the white one in the center has accumulated corpse energy." "Observing Xiang Wuzhan": "The white center of the ghost is like pink catkins, which is said to have accumulated corpse energy. One is called Tianzhi. The main death temple. "Ghost belongs to the constellation Cancer, and the four stars of Ghost (Cancer gamma, delta, eta, theta) are all small stars of the fourth and fifth magnitudes. The so-called corpse air in the center is a star cluster, called Beehive in the West, and its scientific name is M44. In the popular Japanese comic "Saint Seiya" a few years ago, the Cancer Gold Saint's unique move is called "Corpse Energy Underworld Wave". Galileo once thought that the corpse gas was a star. When he first used a telescope to observe this star cluster, he found that there were more than 40 stars in it, and he couldn't help but be surprised. More than a thousand years ago, the summer solstice was located in the constellation Cancer, and the sun shined directly on the Tropic of Cancer on the summer solstice. Therefore, the Tropic of Cancer was called the Tropic of Cancer in the West. Venus is currently orbiting near M44.

Liu’s original name is 宮, 宮 means bird’s beak, which is similar to the meaning of horns, which are dragon horns. "Erya Shitian": "The willow is called Liu, Liu, quail fire", and the note says: "Quail, the name of the bird; fire belongs to the south." Liusu Baxing has a curved shape, like a bird's beak, and also like a weeping willow. "Bu Tian Ge": "Liu Baxing, the curved head is as heavy as a willow." Liu, Xing, and Zhang Sansu all belong to the constellation Hydra. Liu Su is located at the head of the snake. The brightest one is Liu Xing (Zeta Hydra), a third-magnitude star.

Star, also known as seven stars, there are seven stars in the world. "Book of Rites·Yue Ling" says: "The moon of Meng Chun is among the seven stars on the first day", which refers to it. "Historical Records of Tianguan Shu": "Seven stars, neck, are officials, responsible for urgent matters", "Historical Records Suoyin": "Neck, the neck of a red bird. Officials, throat. Things in the throat will not stay for a long time, so Urgent matter. "The stars are located in the heart of Hydra. The brightest one is Hydra Alpha, which is a second-magnitude star. "Bu Tian Ge": "Seven stars are like hooks and willows growing below, and the stars are in the shape of seventeen Xuanyuan", which points out the relative positions of the stars. Regulus here is a famous star group, called Leo in the West, and Regulus is the alpha star of Leo.

Zhang, "Erya": "The bird Zhang Cui", annotated: "Cao, the place where birds eat." It can be seen that Zhang Su took the intention of the red bird. "Historical Records" has another reference: "Zhang means that everything is Zhang." The six stars of Zhangsu are shaped like an open bow and arrow, and they are all small stars of fourth and fifth magnitude, among which the brighter one is Zhangsuer. (long snake lambda). Wings are also taken from the red bird. "Historical Records Tianguan Shu" states: "The wings are feathers."

The twenty-two stars of the Wings are shaped like outstretched bird wings, part of which belongs to the constellation Hydra, and the rest to the constellation Giant.

Zhen is written as a chariot on the lid of the lacquer box of Zeng Hou Yi’s tomb. "Historical Records of Tianguan Shu": "Zhen is a chariot", and "Suo Yin": "Zhen has four stars in the middle and two more stars. "Zhen" refers to the small iron rod inserted on the axle to prevent the wheels from falling off. The four stars of Zhensu and the left and right stars all belong to the constellation Corvus. "Xibu Tiange" says: "The four stars of Zhensu are not square, and the black one of Changsha is hidden in the middle." Changsha is a fifth-magnitude star, and its scientific name is Zeta Corvus.
