Fixed Zodiac, and despite the fact that with the outer planets the difference between the tropical and the sidereal periods
becomes considerable. These values, in tropical years, are:
Jupiter.... 11.858
Saturn..... 29.42
Uranus..... 83.75
Neptune... 163.74
Pluto..... 245.33
The hypothetical Fixed Zodiac is measured along the Invariable Plane, to which the Ecliptic has a minimum inclination
of 0° and a maximum of 3°6'. Its zero point coincides with the point of beginning of the precessional movement of the
Poles of the Ecliptic, but the location of this point has not been determined. Probably it should be the Nodes of
intersection of the Invariable Plane with some as yet undiscovered superior orbit. However, one can assume an arbitrary
point, and from that point compute both the total precession and its changing rate during a given period. There is some
justification for assuming a coincidence of the moving and fixed zodiacs at 28 A.D., less a correction of 281y for lag
and lead. Applying to this the true rate of precession during the intervening period yields the year 1906 as possibly the
commencement of the Aquarian Age in terms of the Equinox, and 2169 in terms of the Pole.
Jupiter Cycle. The ancients noted these first and second order recurrence cycles in connection with the orbits of Jupiter
and Saturn, which they termed the great chronocrators, because of the way the cycles subdivided time into large units of
hundreds of years, and the economic and political evolution which followed in step with these advancing cycles.
Jupiter conjoins Saturn in 19.859 years at an advance of about 123 degrees. After three conjunctions, 59.577 years, it
recurs at a mean advance of 8.93° - the first order recurrence cycle of Jupiter-Saturn. With this 9-degree advance every
60 years, in 40 conjunctions the advance moves around the circle and in 794.37 years returns to within 0.93° of the
starting point - the second order recurrence cycle. This 1° discrepancy would thus locate a third order recurrence cycle
in 360 times 800 years, roughly speaking, a period too far in excess of recorded history to be useful as a frame of
reference.
The first order recurrence cycle of Jupiter-Saturn, 59.577 years - all values are mean values, based on mean motions - is
probably the 60-year cycle of which the ancients spoke so much: the period of "social lag," or the time between the
introduction of a new invention or social innovation (Uranus), and its adoption and spread on the institutional level of
organized society (Jupiter-Saturn). The second order recurrence cycle of these two planets is the Great Mutation cycle
which meant so much in the Mundane Astrology. of the ancients. More recent is the discovery of a cycle of this length
by a modern non-astrological historical investigator, Dr. J. S. Lee, who with the aid of Lin Yutang and Dr. Hu Shih, one
of China's great scholars, studied the incidence of civil conflict in China from 1100 B.C to 1930 A.D. His graph of the
amount of civil conflict in five-year intervals from 230 B.C. to 1930 A.D. reveals an 809-year cyclic interval from the
Chin Dynasty of 221 B.C. to the Sui Dynasty of 589 A.D.; followed by a 779-year cyclic interval from this Dynasty to
the Ming Dynasty of 1368 A.D. Averaging Bogy and 779y gives a mean value of 794y, which would end the third cycle
about 2.159 A.D. In the first half of each cycle, other than for two short-lived peaks of violence the country was
completely peaceful and prosperous, with unity prevailing. In the second halves there are 5 peaks of violence and no
interval of sustained peace. The start of each of the three cycles was marked by great building and engineering activities:
in the Chin, by the Great Wall and huge palaces; in the Sui, by the Grand Canal and huge palaces; in the Ming, by the
rebuilding of the Great Wall and several systems of canals. Notable, astrologically, is the fact that the first Jupiter-
Saturn conjunction in a Water Sign, Scorpio, occurred 3 years before the Chin Dynasty, 18 years before the Sui Dynasty
and 3 years before the Ming Dynasty. The change of clement, in this case from Air to Water, was anciently termed the
Trigonalis, and deemed to be of prime political and economic import. According to Ralph Kraum, the conjunction of
