Each region received the name from the main constellation in it predominant and all those cut by the line of the ecliptic (line that in the sky, seen of the Land, represents the way covered for the Sun during the year) had passed to be considered zodiacais. It agrees to explain that the zodiac is a circle or band of 17 degrees in the sky, that encloses all the celestial sphere and that it has in the center the line of the ecliptic. It was in such a way, then, that the zodiac finished for being awardee with 13 regions or constellations, that are: Aries, Bull, Twin, Cancer, Lion, Virgin, Pound, Scorpion, Ofico, Sagitrio, Capricrnio, Aquarium and Fish. It agrees to point out again that to be considered zodiacal the constellation it must be crossed by the line of the ecliptic, that is, the sun must cross it throughout the year. It happens that after passing for Pound and Scorpion, the sun crosses Ofico of 30 of November the 17 of December, before entering in Sagitrio. However, this ticket of the sun for Ofico is not considered by the astrology.
In the way as it was organized sky for the UAI, all the thirteen constellations occupy different spaces throughout the line of the ecliptic, what it means to say that the division of the zodiac in twelve signs of thirty degrees each one is purely arbitrary and follows only the tradition of the old peoples. Ofico is a in such a way extensive constellation one, being also known for Serpentrio. In mythology Greek, this grouping of stars was associated the Esculpio, god of the medicine. According to legend, Esculpio started to dedicate the art to it of the cure after to see a serpent to make over again another one with some grass that brought in its mouth.
