The symbolism of the linear Zodiac differs somewhat from that of the round one because the circular Zodiac reflects the situation in astrological time, the linear one reflects it in physical time, which always moves forwards.
In the left and right halves of the linear Zodiac the Decans (time) sail in boats along the body of the goddess Nut, who symbolizes cosmic space. Each boat should contain one Decan if they reflect the normal course of events. Let us begin by looking at the left-hand side. The direction of the Decans movement – top to bottom on the left, then moving over to the right, expresses anticlockwise motion as on the round Zodiac.
Beneath the constellation of Leo Decans 1 and 2 are depicted, each in its own boat. Everything is proceeding normally. Then Nut gives birth to the Scarab (Cancer). Time shifts to the right half. The two halves are the symbolic division of the scale of time (history) into two parts: the left before the flood, the right after (the birth of a new time).
In the second half, in the sector of the new-born Scarab (Cancer), at first a little boat floats along the body of Nut containing a Cobra-Decan standing on a lotus (3), but ahead of it are three figures together in a single boat (4). Here is the overlap. This section is marked by the circle.
Three Decans in one boat is an indication of an exceptional event, when three Decans were crammed into the time span of one. Three Decans ended up in one boat because after the catastrophe the Sun recoiled zodiacally two Decans backwards and then resumed its normal motion along the line of the ecliptic through the Decan (1), making a total of three. In other words, in the time allotted to one Decan the Sun passed through three Decans in the sky, which accords with what is shown on the circular Dendera Zodiac.
Combining the testimony of both Zodiacs, it is possible to state with assurance that the entire course of the event in zodiacal terms was as follows: the Earth passed through the Age of Leo and entered the Age of Cancer, spending the first minute of the first degree there, that is to say, one shortened Decan. Therefore, the boat in which the Cobra sits is a small one. And then comes the catastrophe. In terms of the zodiac the Earth makes a "leap in time" recoiling backwards into the Age of Leo. Then, passing once more through the zone from the heart of the Lion to the Crab, the Earth returned to the place where it had been at the moment of catastrophe. Thus, the Earth went through part of the Age of Leo and the initial Decan of the Age of Cancer twice.
The little Decan (3) after which comes the boat with three Decans (4) indicates that the period from the catastrophe and "the breakdown of the precessional mechanism" or "recoil of zodiacal time" to the restoration of the mechanism of precession was brief in comparison with the normal course of zodiacal time in which three Decans of 720 years are equal to an Age of 2,160 years. In the framework of physical time it all took place in the course of a single Decan.
Let us return to the circular Dendera Zodiac. From the point B when, after the restoration of the precessional mechanism, the Sun resumed its normal motion along the line of the ecliptic, if we count off the "new era", just over 18 complete Decans have passed. If we divide the number of years since the catastrophe (13,669) by the duration of a single Decan (720 years) we arrive at a figure of 18,9 Decans. The difference between the timescale in the Dendera Zodiac and simple arithmetic calculation comes to 0.9 Decans. Converting that into years, we get a figure of 648. This means that the "wrinkle in time" (the backward shift of zodiacal time) amounted to something over 600 years.
All these peculiarities with the Decans (in the compilation of the Zodiacs, taking into account the margin of error due to the gradual, almost imperceptible change in the tilt of the Earth's axis) produce the discrepancy of 608 years that exists between modern astronomy and astrology.
Lacking a belief in the profundity of the Ancients' knowledge, neither astronomers nor astrologers have even thought to seek an explanation for this obvious divergence in their views from the Egyptians. Meanwhile Egyptologists, archaeologists and historians are insufficiently versed in the fundamental sciences to, at the very least, properly formulate the question.
In practical terms, the events described above led to the world's zodiacal clock today showing the incorrect time – everything has long since changed. Yet not in a single publication, nor in conversations with professional astrologers will you manage to find out the reason why astrologically the Earth is considered to have already entered the Age of Aquarius. The spring equinox, the event that determines the name of the Age, occurred on 18 March in 2006. On that day the sunrise showed that roughly three-fifths of the distance through the constellation of Pisces had been covered and that the transition of the equinoctial sunrise into the constellation of Aquarius will take place in another 608 years. The International Astronomical Union has designated 2614 as the date the Age of Aquarius will start. It's quite easy to work this out for yourself by looking attentively at the sky and doing a little work with a calculator. Thus, people who travel the ocean of life trusting in the astrologers and astrological charts have found themselves (and will continue to do so) in the same position as Christopher Columbus, trying to find America with an antediluvian map. As you will recall, he missed his intended destination by almost a thousand miles! The same thing awaits those who try to orientate themselves in the confused currents of life using an old astrological chart. In practice, the astrological rhythms of horoscopes do not in any way accord with the real rhythms of cosmo-energetic and cosmo-social cycles; hence astrology exists in an abstract time and so is still not considered a science and exists in a state of discontinuity with reality.
In concluding this section, it is worth noting that the main motive for the conclusion drawn above is not connected with the ethics of astrology. There are things incomparably more important. Astronomers and astrophysicists who study the question of an asteroid threat state that the Earth collides with a substantial cosmic body less than 100 metres across once every hundred years and with one over 100 metres across once every 5000 years. A collision with an asteroid a kilometre across is possible once in 300,000 years. Once in a million years a collision with something over five kilometres across is a possibility.
The surviving ancient chronicles and our research summarized above shows that the real picture is not so optimistic. In the past 16,000 years large asteroids, dozens of kilometres across, have struck the Earth twice: 13,669 years ago (the Azores asteroid) and 2500 years before that (the Pacific asteroid).
