In the third post Atlantean epoch or cultural age is the Egypto/Chaldean Age. Unlike the previous Persian Age one could say that the individual human being had a sentience that , which came about from the divine, and brought forth wisdom. this was the time for the development of what in Anthroposophy as the "sentient soul".
the Chaldean scientist brought this sentient ability to the cosmos and effectually were the precursors of our modern science of astronomy/astrology and science in general.

The ratcheting down of the human consciousness from Persia to Chaldea is manifested in this science with the human being having an "instinctive sentience' through which "wisdom or knowledge" evolved. this is also apparent in the Egyptian world,during this period of time in which the Egyptian saw the heavens as the "script of the gods". This Egyptian also saw themselves as contained within this script and actually made of this stellar script.
This Egyptian, through initiate wisdom and related to the Pharough, would then guide his culture and life in the sense that he and all of mankind were moving together with the progression of the stars (includes the planets). You and I may know of this from grammar school history that the Egyptians planted crops referent to the flooding of the Nile but it was more of a inner cognition of the regularity of heavenly movements. An example ws that the movement of the sun, relative to the stars, presented a regularity as the rhythm of the heartbeat in relationship to the breath presented a regularity. The Inner Egyptian sensed these regularities within the "sentient soul" which led to wisdom.
Again, the intellect had not come to earth, within man, but there were the beginnings of writing or script during this time period. Ancient languages were written down to a lesser or greater extent.
A very interesting presentation came about which has become known to us as "The Platonic Year".

From reading the reference it becomes almost inconceivable, given our present intellectual understanding, as to how the ancient Chaldean/Egyptian scientists could come to this realization.
I'll give what I've got and the reference may help. the Great Year consists of a period of about 25,920 years. This number is ascertained by observation of the sun traveling through the universal space and noting when the spring equinox appears with the 12 zodiacal star formations in the background.
Eight hundred years before the birth of Christ the sun entered into the sign of Aries and we are now within the sign of Pisces. The Lamb or sacrificial lamb is associated with the Aries sign or lamb. prior to this the sun was within the sign of Taurus the Bull (Egyptian period) and the Egyptians worshiped Apis and the Persians worshiped Mithra the bull. In the first post Atlantean time (Old Indian) the sun rose in Cancer or interweaving spirals.
To get the picture, the sun travels and in the background are the Zodiacal stars and each year the sun travels from on sign to the next. This period of movement is 25,920 years to complete the cycle. OK, now sit on your hands and note that I previously wrote that each of the cultural ages were of a period of 2160 years; 2160 * 12 = 25,920.
I'm really only trying to give the idea that the ancient Egyptian/Chaldean had a inner sentient ability to read the stars or cosmos and bring forth this wisdom or knowledge. The mental abilities (better word?) of humankind is in evolution .
I've posted this before but to me its amazing so if , on average, the human being takes 18 breaths per minute within one hour the number of breaths is 60*18= 1080 breaths per hour *24 hours in a day = 25,920 breaths per day. the cosmos within.... Peace
