The first zodiacal constellation, originally corresponded to the vernal point, that is
to the point in which the eclittica (the apparent run of the Sun on the celestial time)
intersected the celestial equator and also the moment in which it began the spring
season: for this motive the Aries has always been symbol of the rebirth (from the dark
and from the winter cold), power, first movement of the life.
The Aries substantially founds its myth upon that Roman, in base to which a ram
aries by the gold fleece saved Frisso and Elle, children of Nefele, from a conspiracy
of their stepmother that they wanted offered in sacrifice for charm a
famine from her provoked. Elle fell, dying, during the trip in rump on the ram, on
the river that was called Ellesponto in his honor. Frisso, brought instead in safe
in the Colchide, it sacrificed the ram to Zeus, it nailed the gold fleece of it to an
oak and image (bare of the fleece, for this not very bright) it was set
in the sky by Nefele in memory of the savior of his/her children.
Frisso, decided to get the hand of the daughter of the terrible King Aeta, he/she
offered the fleece to her father, that left it on the oak guarded by a big
sleepless snake.
Subsequently Frisso died and his cousin Pelia became unjustly the sovereign of Iolco
in Tessaglia  title that was up to in reality to Giasone. Pelia one day
challenged Giasone to bring him the gold fleece of the Aries, in exchange of its
throne: it was so therefore that Giasone and other 55 heroes (the Argonauts)
undertook the famous trip on board of the ship Argon, to the conquest of the fleece.
The Argonauts introduced him to the King Aeta, that refused their
request. Meanwhile Medea, the daughter of Aeta, fell in love him of Giasone,
and she contrived for him a plan to steal the fleece: she convinced with the
deception the sleepless snake to fall asleep, of way that Giasone could easily remove
the fleece from the oak and to escape away with her, pursued by the sentries of the King.
They arrived healty and save and they used the fleece like a nuptial cover.
