Sky Observation in Ancient Times
Long before men raised crops depended on hunting as well on land and sea recollections; the Moon with its phases and influence on tides and weather will indicate the time to collect fruits, grain, seafood, fishing time, hunt migrating animals and foretell weather changes with certain exactitude.

As far back as 35 thousand years or more they made small statues representing voluminous women that are called Venus and men with Lion characteristics which are astronomical representation meaning that they depended on the sky observation.

Farther on, the four principal constellations were represented by The Lion, Eagle, Snake and Men; The Lion on the Ground, the Eagle on the Air, the Snake Underground and water and Man that as well could hunt in the tree environments but in addition had more intelligence or the way they provide their food, by force (Lion), audacious (Eagle), ambush (Snake) and intelligence (Man) but all are hunters.

Planet Earth takes 365.25 days to go around the Sun making with it a year, the Moon takes 29.52 days to go around Earth which is about the time of a month and divides the year in twelve parts (known as Solar Year) but in addition the Moon concerning its position in to the Ecliptic takes 27.3 day to go around and arrive to the same point, which divides the ecliptic or year in 13 parts rather than 12 and known as the Lunar Year.

The sun concerning the equinoxes also show an additional movement which is likely the sun rotation around the center of the galaxy, for such reason each 72 years moves one degree giving a total of 25920 years to make a complete circumference. This time period is known by the Precession of the Equinoxes and also as Plato’s year in honor of the Greek philosopher that revealed to the general public its knowledge.
