[Carl Jung and Astrology, Pisces, Aquarius]
The northerly, or easterly, fish, which the spring-point entered at about the beginning of our era, is joined to the southerly, or westerly, fish by the so-called commissure.
This consists of a band of weak stars forming the middle sector of the constellation, and the spring-point gradually moved along its southern edge.
The point where the ecliptic intersects with the meridian between the two fishes coincides roughly with the sixteenth century, the time of the Reformation, which as we know is so extraordinarily important for the history of Western symbols.
Since then the spring-point has moved along the southern edge of the second fish, and will enter Aquarius in the course of the third millennium.[Footnote 84.]
Astrologically interpreted, the designation of Christ as one of the fishes identifies him with the first fish, the vertical one.
Christ is followed by the Antichrist, at the end of time. The beginning of the enantiodromia would fall, logically, midway between the two fishes.
We have seen that this is so. The time of the Renaissance begins in the immediate vicinity of the second fish, and with it comes that spirit which culminates in the modern age. ~Carl Jung; Aion; Page 94
Since the delimitation of the constellations is known to be somewhat arbitrary, this date is very indefinite.
It refers to the actual constellation of fixed stars, not to the zodion noeton, i.e., the zodiac divided into sectors of 30 each.
Astrologically the beginning of the next aeon, according to the starting-point you select, falls between A.D. 2000 and 2200.
Starting from star “O” and assuming a Platonic month of 2,143 years, one would arrive at A.D. 2154 for the beginning of the Aquarian Age, and at A.D. 1997 if you start from star “a 113.”
The latter date agrees with the longitude of the stars in Ptolemy’s Almagest.
