Then Nadi Astrology in the 28th deccan which would be the culminating deccan at the what we would call like the equal house midheaven basically the 90 degree point from the rising deck in was associated with livelihood the 25th deccan was said to be associated with weakness the 19th deccan which is the setting deccan opposite to the rising deccan was associated with injury
So the 17th decan was associated with marriage and the person's wife the 10th deccan was associated with death and that's the deccan that would be associated with like the equal house ic or the lowest point in the chart in some sense and then finally that they called the eighth deck in the door of hades and it was the place that signified children so we don't know very well the timing of this text and when it came from basically we don't know when this text dates do.
But we we assume we think it dates to sometime around the first century bce or maybe the second century bce so it may represent this stage where the egyptians were using the deccans to create something like a prototype for what later became the concept of the 12 houses which is where you divide the diurnal rotation into different sectors and then you start associating or assigning it topics based on where the signs of the zodiac fall relative to the rising sign in this context
There starts to be exchanges that start start happening between the astrologers in mesopotamia and egypt and the earlier astrological traditions from mesopotamian egypt start being synthesized at least by 300 bce where we start seeing the zodiac appearing and being merged with the egyptian deccans in egyptian temples at this time and we start seeing the zodiac like appearing in egyptian temples and that's kind of an important development because all of a sudden it indicates that the astrologers were exchanging information.
And their traditions were starting to interact in a really significant way so eventually this reaches a really crucial but somewhat mysterious turning point around 100 bce when we see the emergence over the course of the next century basically in the first century bce of what we now call today hellenistic astrology and hellenistic astrology is a type of astrology that emerged during the hellenistic period after the conquests of alexander it came out of egypt
But egypt was under the control of greek-speaking rulers at the time a dynasty that was started by one of alexander's generals named ptolemy installed themselves as the the king or the pharaoh in egypt and then there was a long dynasty of rulers that came after that that spoke greek this is also when we get the founding of the famous library of alexandria and other things like that astrology.
So one of the things that comes about after a century or two of that is this new system of astrology kind of appears out of nowhere to some extent and it's it represents the establishment of the four-fold system of astrology that we still use today that uses the planets and most of the things that we associate with the planets today the signs of the zodiac and most of the qualities
That we still associate with the signs of the zodiac today the concept of the 12 houses and most most of the basic meanings of the houses that we still use today and the concept of aspects which is the fourth other major piece of the system which which is introduced at that time and is still for the most part the core of it is still essentially the same today 2000 years later
So this basically represents the emergence of hellenistic astrology represents the introduction of all of the basic concepts of western astrology or most of the basic core concepts that we still use to this day and it partially represents a synthesis of the earlier mesopotamian and egyptian astrological traditions and it also partially represents at the same time some new innovations and some new techniques that don't appear to have existed prior to that point being introduced at this time
So it's this interesting and weird balance between inheriting the old traditions and synthesizing them together with some new innovations that are being introduced around that time which is a a thing that we'll see come up over and over again in the history of astrology over the next several centuries so what seems to have happened is they took the 12 signs of the zodiac which is the movement of the planets along the ecliptic and they started to merge it with the concept of the 36 decans
