Mythology of  Piscis

     Piscis or the fish, hay several versions of why both fish appear in the sky. Higinio speaks of an egg that fell to the Éufrates river, being given back to the Earth by fish. Then Aphrodite left the egg and, in gratefulness to the fish it placed them in the sky. In another one of the versions it is spoken about two fish that rescue to Aphrodite and its Eros son when their lives are in danger.

            Another one of the versions says that terrified by the giant Typhoon, Venus and Cupido they were thrown to the Éufrates river and they became fish. In order to commemorate this event, Minerva placed to the fish in the firmament. The Babylonians knew this constellation like Kun, or the tails; also he knew himself him like the Traílla, to which the two goddesses were tied fish, Anunitu and Simmah.

          Piscis, is a great constellation weak in stars and díficil to detect at first, solely visible in nights I am transparent and far from the lights of the cities. It is visible an equatorial constellation and therefore in all the planet for more than six months between Julio and December, for more than thirty days the Sun remains in her, therefore the ecliptic or apparent line of the movement of the Sun through the constellations crosses the constellation of this a the west, therefore, during months we can observe always some planet or the same Moon crossing it of this a the west.

         Form leaves from the zodiacal sign and at the moment, by the precession of the equinoxes is the first point of Aries that indicates the position of the Sun when the spring in the North hemisphere begins or cuts the ecliptic of the south to north, does more than two thousand years the first point of Aries was in the constellation of Aries.

            One is in a moved away zone of the equator of the Milky Way or our galaxy for that reason he is observable few stars and an important amount of galaxies, since it represents a window opened the deep sky of the observable galaxies from our planet Earth.

            Piscis limits the north with the constellations of Andromeda and Pegasus, to the east with Pegasus and Aquarius, to the south with the constellations of Aquarius and Cetus and to the west with Cetus, Aries and Triangulum.

            Piscis I located the 24 to it of August of 1982 at the age of 16 years from the locality of Can Picafort, Majorca, Spain.
