Description of the signs of zodiac

Aries:

In Hellenistic astrology, the sign of the ram was mythologically associated with the golden winged ram that rescued Phrixos and his sister Helle from the altar where they were to be offered as a sacrifice to Zeus. The golden ram carried them to the land of Colchis but on the way Helle fell into the sea and drowned. When Phrixos arrived at Colchis he sacrificed the ram to Zeus and presented the Golden Fleece to his father-in-law, the King of Colchis. The fleece was then hung upon a sacred oak and guarded by a dragon until rescued by Jason and the Argonauts. The myth recounts that Zeus was so moved by the ram's fate that he gave it the greatest honour of being moved to the heavens

Taurus:

In Greek mythology, Taurus was identified with the bull whose form Zeus took to rape Europa, a legendary Phoenician princess. In illustrations, only the front portion of this constellation is depicted; in Greek mythology this was sometimes explained as Taurus being partly submerged as he carried Europa out to sea. Greek mythographer Acusilaus marks the bull Taurus as the same that formed the myth of the Cretan Bull, one of The Twelve Labors of Heracles. 

Gemini:

The ancient Greek tale of the egg-born brothers Castor and Pollux, born to their mother Leda after she was seduced by Zeus in the guise of a swan. Their consummation, on the same night as Leda lay with her husband, Sparta's King Tyndareus resulted in the birth of immortal Pollux, who possessed great physical strength, and mortal Castor who possessed great ingenuity. Upon Castor's death Pollux begged Zeus to let him share his own immortality with his twin to keep them together and they were transformed into the Gemini constellation.

Cancer:

According to an ancient Greek legend, the figure of a crab was placed in the nighttime sky by the goddess Hera to form the constellation Cancer. Hera swore to kill Heracles, the most famous Greek hero. Hera attempted to kill Heracles in many different ways, but each time his incredible physical strength allowed him to survive. Hera cast a spell of madness on Heracles, causing him to commit a great crime. In order to be forgiven, he had to perform twelve difficult tasks. One of these tasks was destroying the terrible nine-headed water-serpent, Hydra.

During the battle between Heracles and Hydra, the goddess Hera sent a crab to aid the serpent. But Heracles, being so strong, killed the crab by smashing its shell with his foot. As a reward for its service, Hera placed the crab's image in the night sky.

Leo:

The Lion of Nemea, killed by Heracles, who strangled him, because his skin was impenetrable. The hero with his own claws (the one thing that could hurt him) skinned and stayed skin as its symbol.

Virgo:

Erigone was the name by which the first century astrologer Marcus Manilius referred to the constellation. As the sign of the harvest, Virgo held strong connections with the time that grapes were gathered for the production of wine and Erigone represents an aspect of this association. She was the daughter of Icarius, who received the secret of wine making from the Wine God, Dionysus, and was murdered by peasants who believed they had been poisoned by his wine. Erigone was led to discover his body by their faithful dog and hanged herself in grief. The gods were moved to pity over the tragedy and transported the family to everlasting glory in the heavens: Icarius became Boötes; Erigone became Virgo, and the dog Maera, the constellation Canis Minor.

Libra:

The symbol for Libra is the Scales. In Roman mythology, Libra is considered to depict the scales held by Astraea, the goddess of justice. Libra is also considered the goddess of balance and truth. She also corresponds with Egyptian mythology as Ma'at, the goddess of the scales or balance.

Scorpio:

In Greek mythology, the Scorpio is featured in the myth of the giant hunter Orion and the Goddess Artemis. According to the Phenomena of Aratus, Orion was enjoying the slaughter of all manner of beasts when he laid his hands upon Artemis's robes. In anger she proved his vulnerability by rousing the deadly scorpion whose unsuspected bite destroyed the supposedly invisible hunter. The goddess raised the Scorpion to the heavens in gratitude, placing its constellation in opposition to that of Orion. The scorpion and the hunter are thus said to be linked forever in conflict in the sky, such that Orion flees beneath the western descendant whenever his murderer rises in the east.

Sagittarius:

The centaur Chiron was a great educator in music, art, hunting, medical and surgical. Heracles accidentally shot an arrow poisoned with the Hydra’s blood during a fight with the Centaurs, whom fled to the abode of Chiron. He contracted a painful wound incurable, which led him to give up his immortality to Prometheus, and to die and escape the pain. He was promoted to heaven as the constellation Sagittarius.

Capricorn:

Represents a half goat half fish Amalthea, who breed and fed Zeus when he was a baby, in whom Rhea entrusted to protect him from his father Cronus. Amalthea and her daughter raised Zeus with honey and milk, she had impressive horns that grew and spilled nectar and ambrosia, and when they broke filled it with fruit and offers it to Zeus. From that event, Zeus placed her in one of the constellations in the sky.

Aquarius:

Aquarius is identified with Ganymede, a beautiful youth in Greek mythology with whom Zeus fell in love and, in the disguise of an eagle (represented by the constellation Aquila), carried off to Olympus to be "cup-bearer" to the gods.

Pisces:

According to one Greek myth, Pisces represents the fish into which Aphrodite and her son Eros transformed in order to escape the monster Typhon; they are tied together with a cord on their tails, to make sure they do not lose one another. Alternatively, the twin fish were placed in the heavens in honor of their heroic deed of saving Aphrodite and Eros from Typhon on the river Euphrates.

*Ophiuchus:

Astronomy join Ophiuchus in 2011 as the thirteen zodiac sign, since then has been discussed in astrology about add this sign, there are a group, what say that the astrology must follow with the Babylonian tradition of twelve signs, and another part believe that this sign should be added to give an answer to certain type of personality that so far has not been represented by the current zodiac signs, this second stream is very important in the eastern tradition. His mythological history we can indentify in the ancient Greece, Ophiuchus corresponds to Asclepius, son of the god Apollo and Coronis. He developed such skill in medicine, stating that he could even raise the dead. Very offended by it, Hades asked Zeus to kill him for violating the natural order of things, to which Zeus agreed. However, as a tribute to his worth, he decides to place it in the sky surrounded by the serpent, a symbol of renewed life.
