The Romans came up with the idea of the goddess fish in the myth of Venus and her son Cupid.

To make sure that not be lost, were tied with a rope. In the sky we see, therefore, to both mother and child, which are united by a rope.

Pisces, the 12th zodiacal constellation, it is difficult to locate because the stars that compose it are very faint; none of them exceeds the magnitude 4. The figure consists of two fish tied by their tails with a rope; the fish eastern swims in the vertical direction, while your partner is oriented toward the west and located just a few degrees above the equator, more or less parallel to this. A ring of five stars, which in some occasions, they have received the name of the wheel, is located immediately south of the great Square of Pegasus, and to the south, but slightly to the east of the bright star Markab. The head of the fish, that swims, toward the north is about to collide with Andromeda, and it is easy to find it exactly to the south of Mirach. In the eastern end of this constellation, the rope that binds the fish is indicated by the star Alrischa. Pisces has its peak between the end of September and principles of October.

Its height is given at the beginning of August, but the combination of clear skies and its location at the south of the equator make this constellation is appreciated very little since middle and high latitudes in the northern hemisphere. You can locate by drawing a line from Vega (constellation Lira) that pass by Altair (from the constellation of the Eagle) going through the Milky Way, until you reach Algedi and Dabih, which are the stars alpha and beta of the horns of the goat.

Libra


Mythology:
The balance symbolized the identical duration of the day and night in the equinoxes: two millenniums ago, the passage of Sun to Pound marked the equinox of September. Were the roman’s astrologers who interpreted the scales of Libra as justice, subject by Astrea, the goddess of justice.

Libra is the seventh sign of the zodiac, is situated between Virgo to the west and Scorpio, to the east. Due to its low visual charm, it is easier identification from Scorpio. To do this we will have to extend the claws of the scorpion to form a few large claws. The tip of the scales, Zuben Elgenubi is almost exactly on the ecliptic, half way and a few degrees north of a line that extends between Spica (Virgo) and Antares (Scorpio). Pound has its peak at the beginning of may; you can see it from all latitudes except from the arctic region.

Their stars more significant are:
- Zuben Elgenubi, which means "clip of the south". It is a blue star-white of magnitude 2.8 .
- Zuben Eschamali, means "clip of the north". This star is emerald green in color and its magnitude is 2.6 .
