1433 - Aquarius became heliacal rising constellation at the Vernal Equinox (or as early as 1431)
            The next precessional age, the vernal equinox will be on Pisces/Aquarius.

Graves: "2200 AD" zodiac: scorpion at winter solstice, bowman, goat, waterman at spring equinox, fish, ram, bull at summer solstice, twins, crab, lion at fall equinox, virgin, scales (page 380-381)

For roughly two thousand years official terminology has used only zodiacal "signs," each of which occupies 30 degrees of the 360 degrees of the whole circle. These signs have the names of the zodiacal constellations, but constellations and signs are not congruent, the equinoctial sign (=1 degree - 30 degrees) being called Aries regardless of the constellation rising heliacally on March 21 is Pisces, but the "sign" preserves the name Aries, and will continue to do so when in the future Aquarius rules the vernal equinox. [Hamlet's Mill]

Zodiacal constellations are not inherent but defined by ancient astrologers. They could have made any collection of stars anywhere on the ecliptic into any number of constellations. – which is what happened. The Hindu’s have 29 asterisms or mini-constellations around the ecliptic, while the Egyptians had thirty. Before the 12 zodiacal constellations there were evidently only six according to some archeo-astronomers. The only reason I bring up these points is that the 12 zodiacal constellations are only relevant to the ages if they were defined to calibrate or mark the ages by the ancient astrologers.

Most researchers in this area follow an intellectual approach divorced from substantiation or proof. I prefer support to any argument that I put forward. For example the earliest known depiction of the zodiac shows not only the zodiac but also a `micro-zodiac’ with 12 sub-signs placed within each sign – along the lines of the contemporary Hindu dwadasamsa (abbreviated to dwads). If dwads exist within ages, then each dwad is approximately 179 years each. While it may be difficult to rectify where ages of 2150 years each may sit, these smaller periods of approx 179 years are much easier to locate.

Based on 18 years of research into this area, I have found the dwads of ages and these dwads indicate that the Aquarian age commenced around 1400 AD. This date is astronomically supported by the heliacal rising of the zodiacal constellations. The constellation of Aquarius has been heliacally rising at the Vernal Equinox for centuries as should be expected for an Aquarian age commencing within a few years on 1400 AD.

The Equinoctial Point method that has monopolised the calibration of the ages via the zodiacal constellations since the time of the ancient Greek astrologer Hipparchus (c.125 BC) is incorrect as Hipparchus did not understand the methodology of the ancient astrologers one to two thousand years before his time. It is the ancient astrologers of Mesopotamia that defined the zodiacal constellations – not the ancient Greeks. Because Hipparchus did not understand the background to the zodiacal constellations he messed up the approach he developed.

So while the Equinoctial Point has centuries to go before it enters the constellation of Aquarius, the constellation of Aquarius has been the heliacal rising constellation at the Vernal Equinox for many centuries.

Mayan Sacred Calendar: National Underworld: Heaven 13: Day 7: Fruition - 1617 - October 28, 2011

The most general outbreaks [of the Black Death] in Tudor and Stuart England, all coinciding with years of plague in Germany and the Low Countries, seem to have begun in 1498, 1535, 1543, 1563, 1589, 1603, 1625 and 1636.[34]
The plague repeatedly returned to haunt Europe and the Mediterranean throughout the fourteenth to seventeenth centuries, and although bubonic plague still occurs in isolated cases today, the Great Plague of London in 1665–1666 is generally recognized as one of the last major outbreaks.[35]
Late outbreaks in central Europe include the Italian Plague of 1629-1631, which is associated with troop movements during the Thirty Years' War, and the Great Plague of Vienna in 1679. About 200,000 people in Moscow died of the disease from 1654 to 1656.[36] The last plague outbreak ravaged Oslo in 1654.[37] In 1656 the plague killed about half of Naples's 300,000 inhabitants.[38] Amsterdam was ravaged in 1663–1664, with a mortality given as 50,000.[39]
A plague epidemic that followed the Great Northern War (1700-1721, Sweden v. Russia and allies) wiped out almost 1/3 of the population in the region.[40] An estimated one-third of East Prussia's population died in the plague of 1709-1711.[41] The plague of 1710 killed two-thirds of the inhabitants of Helsinki.[42] An outbreak of plague between 1710 and 1711 claimed a third of the Stockholm’s population.[43] [http://en.wikipedia.org/wiki/Black_Death]

2002 - The equinox axis became perpendicular to the galactic axis. [Cross of Hendaye page 239]
            Leo now falls on the autumn equinox (reverse of 11527 when it fell on the spring equinox)
            Sept 23 sun rose on cusp of Leo/Virgo, with the near-full moon setting on cusp of Aquarius/Pisces (Hendaye page 330)
            2002: autumn equinox = midpoint of last Mayan katun.
            Earth's tilt at balance point, its "fixed standstill" [Cross of Hendaye page 333]

"Standing again on Giza between the paws of the Sphinx, we note that on the morning of the summer solstice, June 21, 1992, there was a partial lunar eclipse in Scorpio, in opposition to the rising sun in Taurus/Gemini. This is the starting point of our twenty-year countdown, and matches the moon-four A's alignment on the Hendaye cross, even to the partial eclipse of the moon face."

"Even better is the winter solstice, December 21, 2012, when the sun rises in perfect alignment with the center of the galaxy on the cusp of Scorpio/Sagittarius, while the moon sets on the cusp of Taurus/Gemini. On the summer solstice at the beginning of our apocalyptic season, the moon was conjunct the center of the galaxy and the sun was in opposition. On the winter solstice, the end point of the period, the sun will be conjunct the galactic center and the moon will be in opposition. . . . Thus the solstice alignments, as revealed on the Hendaye monument, act as brackets or bookends to our midpoint of September 22, 2002, defining a twenty-year period as the season of apocalypse." [Cross of Hendaye page 337]
