The concept of the zodiac was originally proposed by the Babylonians before 2000 BC C., as a schedule to be displayed over time.
Experts say that the trail of the origin of our constellation is found among the Sumerians, but it is the priest-astronomers or astrologers if you will, of ancient Egypt who reported their observations of the sky to the Greeks, who in turn were a source of knowledge for astronomers and scientists from the Middle Ages.
In astrology, the zodiac constellations defined by the twelve zodiacal signs used historically as a method of divination and preparation of horoscopes. The sign present at the time of birth is linked to the being who had just been born, "brand" for life.
The twelve signs as we know them today were listed by the Greek astronomer Claudius Ptolemy in the second century, based on the Sumerian astrological system.
Although we use the same names for the twelve astrological signs that twelve of the fourteen astronomical constellations of the zodiac, there is a significant difference. While the signs are geometric sections of equal size, each spanning 30 ° and corresponds to a period of approximately one month, the constellations have irregular shapes, not in any case both correspond
The constellations of the zodiac, unlike the rest of the sky are those along which the Sun, Moon and planets on their journey in the sky throughout the year. The Zodiac "the way of animals," consists of 12 constellations are: Aries, Aquarius, The Crab, The Goat Marina, The Scorpion, The Twins, The Lion, The Fishes, El Toro, La Balance, Sagittarius and Virgin, not to mention the constellation of Ophiuchus "The Serpent", which some consider him the 13th constellation of the Zodiac.
