Macro-Astrology is a new and innovative branch of astrology focusing upon the precessional ages such as the Age of Pisces, Age of Aquarius etc. Macro-astrology is closely related to mundane astrology. Macro-astrology was titled to differentiate it from mundane astrology and former research upon the precessional ages. To date, precessional ages are probably the most undervalued area of astrology. This is because so much confusion has surrounded them.

The main confusion is that to date, no one has been able to say when one age ends and a new age starts. Macro-astrology does not have this confusion - macro-astrology is based on a relatively accurate rectification of the ages. This high level of accuracy is due to rectification.

Zodiacal Constellations

The main problem to date with precessional ages is the zodiacal constellations. The zodiacal constellations exist in a band around the earth that contains the sun's apparent annual path around the earth. These zodiacal constellations were named in antiquity, probably by at least 2000BC in Mesopotamia. Regardless of their original location and size, the current zodiacal constellations are uneven in size and have been adjusted over the millennia. However the position of the vernal point in the `modern' zodiacal constellations is taken as the key calibrator of the precessional ages.

The point of reference used in studying the precessional ages is the position of the sun at the vernal equinox (spring equinox for the Northern Hemisphere) relative to the background constellations. The vernal equinox is currently in the Constellation of Pisces. The Constellation of Pisces is much larger then the average zodiacal constellation. Therefore it is assumed that the Age of Pisces has a longer duration than most other ages.

Whether by accident or intention, based on the current rectification of macro-astrology, the zodiacal constellations are about half a sign late. Even if the zodiacal constellation were redrawn to be exactly equal size of thirty degrees each, their overall position is half a sign out of phase. However this difference between the position of the vernal point, currently located in the Constellation of Pisces, and a rectification of the ages indicating we are in the Aquarian Age does not mean that the zodiacal constellations are `incorrect'.

There is no guarantee that the ancient astronomer-astrologers used the vernal point as their definitive factor. They may have used the zodiacal constellation differently then the modern method of resorting to the vernal point. One common practice in antiquity was the view of the constellations on the western horizon immediately after sunset. After sunset, the first 12 to 15 degrees above the western did not display any stars or constellations due to the light from the suns' rays. The ancient astronomer-astrologers may have assigned the zodiacal constellations half sign out of place to take this situation into account.

Until it is resolved how the ancient astronomer-astrologers actually used the zodiacal constellations, no conclusion can be reached as to the knowledge the ancient astrologers had about the precessional ages. It is possible that the method used by many present day astrologers is out of synch with the ancient practices. This may explain why very little information with any practical use is has been extracted from these precessional ages in modern times.


Once the zodiacal constellations are removed from the equation, a fresh start can be introduced in any examination of precessional ages. However a second stumbling block has also prevented proper clarification of the ages. This second stumbling block relates to smaller divisions of the ages. Many astrologers in their research on precessional ages have made use of sub-periods or sub-ages of precessional ages. Without fail, a system of dividing each age into 12 sub-ages has been adopted. But a catastrophic approach is then employed to assign signs to these sub-ages.

The catastrophe relates to the methodology. Precessional ages are like a new frontier with no settlers and only a few distant observers gazing through their telescopes at the fabled territory. In trying to get bearings in a foreign territory it is better to use systems that previously have enjoyed success. Instead, astrologers have invented new systems to try and explain this new territory. This new system is the method of assigning signs to sub-ages of precessional ages.

Precessional ages, due to the astronomical nature of the precession of the equinoxes, are permanently retrograde. Normally Aries is the first sign, followed by Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and finally Pisces then back to Aries for a new cycle. The precessional ages reverse this trend. After the Age of Aries, the next age is the Age of Pisces, the Age of Aquarius, Age of Capricorn and so on. No astrologer disputes this.

However when it comes to the subdivision of these ages into sub-ages the most exotic systems are employed. Astrologers stumble over the possibility that these subdivisions also are retrograde. Instead they put in place subdivisions that are in the normal forward order within ages that are retrograde. Astrologers regularly employ sub-divisions of signs in natal astrology, and especially with progressions. However in natal astrology, whenever a planet goes retrograde the signs' subdivisions are not reversed.

The main sub-divisions employed in western astrology are the threefold division of signs into decanates (decans) and the twelve-fold division into dwadasamsa (duads). Astrologers, in applying sub-ages to the precessional ages, are prone to insert the sub-ages in their normal `forward' order while their parent age s are going `backwards'. For example, a Pisces Age with the first sub-age Pisces followed by Aries and so on until Aquarius. If they had taken the lead from natal astrology, the sub-ages should be in reverse of their normal order like their parent ages. Some astrologer even get more exotic and decide that the first sub-age of each age is Aries, followed by Taurus, Gemini and so on until Pisces.

Macro-astrology does not use exotic systems for the subdivision of the ages. If the ages are retrograde - then so are the sub-ages! There is a more `scientific' way of justifying this approach that relies upon the degrees of the zodiac. For example, Aquarius controls from 300 degrees to 330 degrees of the 360 degrees zodiac. The duads of Aquarius, are Aquarius (300 degrees to 302 ½ degrees), Pisces (302 ½ degrees to 305 degrees), Aries (305 degrees to 307 1/2 degrees) and so on until the last duad of Capricorn (327 ½ degrees to 330 degrees). When the world enters the Age of Aquarius, after leaving the Pisces Age behind, it is entering Aquarius at 330 degrees, not 300 degrees. At 330 degrees it first meets the Capricorn duad (327 ½ degrees to 330 degrees).

Though there is ample evidence to support retrograde sub-ages within retrograde ages, this technique, to my knowledge, has not been used outside of macro-astrology. This stumbling block is as fatal as the erroneous zodiacal constellations and has prevented any meaningful progress in the understanding of precessional ages to date.


Macro-astrology ignores the zodiacal constellations and utilises retrograde sub-divisions within retrograde ages. Almost the final piece in the jigsaw puzzle is rectification. The process of rectification depends upon the subdivision of ages. The first sub-age in the Age of Aquarius is Capricorn. An age is approximately 2,150 years long, while a sub-age is only 179 years long. Isolating 179 years periods is easier then looking for the thread that passes through 2,150 years. Historical accuracy only goes back to approximately 1000BC, so if ages were the only criteria in the rectification process then only about one and a half ages are available. In comparison, the same 3,000 years provide approximately 16 sub-ages spread over the 12 signs as vibrant examples for synchronicity to historical events.

The Overflow Effect

Early in my research I discovered the final piece of the jigsaw puzzle, without which the whole rectification process is virtually impossible. This final piece does exist in natal astrology, especially in progressions, but it is overlooked and generally not taken into account. However what is inconsequential in natal astrology takes on another meaning in macro-astrology due to the difference in magnitude. This final piece is what I term the Overflow Effect.

In the technique of progressions in natal astrology, signs do not behave in a staccato fashion. For example, if Capricorn or the 10th House of Career is activated by some strong progression, it can be expected that the person could get promoted, demoted or fired amongst other possibilities. If for example, the person is promoted, when the precipitating progression moves on to Aquarius or the 11th House, this does not automatically undo the previous Capricorn or 10th House developments. Normally whatever Capricorn or 10th House event that was precipitated will `live on' until something directly contrary to it is encountered.

The same is observed with the precessional ages and their sub-divisions. This effect was not discovered through the examination of ages, but through the examination of the sub-ages. For example the first sub-age in the Age of Aquarius is the Capricorn Sub-Age. It theoretically rules a period of time of some 179 years. However what actually happens is that immediately it comes into operation the alert observer will notice an increase in Capricorn activity, albeit sporadic and at a low level. From this point it slowly builds up to its strongest energy at the end of its 179 years period at which point it breaks like a wave and washes over the next sub-age (Sagittarius) and more.

There is a very good reason why sub-ages, ages and any period in macro-astrology are strongest at their ends. This quirk is again due to the retrograde nature of the precessional ages. A quick examination of Capricorn, be it an age or a sub-age reveals two things. Firstly, the three decans of Capricorn are Capricorn, Taurus and Virgo. Due to the retrograde nature, the first decan encountered in Capricorn is Virgo, followed by Taurus and finally Capricorn. Secondly, in a similar fashion, the first duad encountered in Capricorn is Sagittarius, then Scorpio, Libra and so on until the final duad is Capricorn.

At the beginning of Capricorn it is a Capricorn period with a Virgo decan and a Sagittarius duad. At the end of the Capricorn period it is a Capricorn period, Capricorn decan and Capricorn duad. The strongest place for Capricorn or any sign in macro-astrology is at its very end!

Once this Overflow Effect was applied to the 179 years sub-ages it became rapidly obvious that a sub-age would build up its momentum for 179 years then flow over the following 179 years period and more. It made it very difficult to say exactly where each 179 years sub-age should be located, though their location in general was obvious following some minimal research.


The problem with identifying the actual start and end of a sub-age was partially overcome with the further twelve-fold division of sub-ages into micro-ages of approximately 15 years each. Micro-ages follow the same mechanics as sub-ages and ages. Instead of trying to exactly locate a 179 years sub-age with its overflow, the rectification process drilled down to rectifying 15 years micro-ages. These micro-ages also develop slowly over 15 years until they reach their peak energy, then overflow into the following period.

It is due to these 15 years micro-ages that the claim is made in macro-astrology that the rectification of say the start of the Aquarian Age is accurate to within 15 years. The confirmation of the rectification process depends upon each micro-age examined clearly corresponding to historical events and the same for each sub-age. Furthermore it was discovered that the decans of ages and the decans of sub-ages also provide historical synchronicity. All these various periods must demonstrate workable correspondences to historical events using mainstream history.

The Aquarian Age

It is due to the wealth of supporting evidence relating historical events to ages, age-decans, sub-ages, sub-age-decans and micro-ages that, with confidence, I can state that the Aquarian Age arrived within 15 years of 1447 AD. Due to the nature of the Overflow Effect, the 15 years `error' means that the Aquarian Age arrived in 1447 AD or up to 15 years earlier.

Though the Aquarian Age commenced within 15 years of 1447 AD, it remains an infant because astrological periods in macro-astrology are weakest at their beginnings. The overflow from the Pisces Age however is incredibly strong, and I believe that it remains the dominant sign in the world today. Aquarius has extracted some concessions - the discovery of the New World (America), the scientific revolution plus the rapid growth of democracy and personal freedom in the last 500 years to name a few major examples. It is early days yet for Aquarius. The experience of Aquarius in full swing must wait until around 3600AD and beyond, in its overflow. In the meantime the world must muddle its way through the Pisces Age Overflow.


Over ten years of research has clearly indicated to me that historical events tightly correspond to the ages, sub-ages, micro-ages etc, but only for an Aquarian Age commencing in the mid 15th Century. No other rectification to date comes even close to this
