| THE
HOW AND WHY OF THE MAYAN END DATE IN 2012 A.D.
by John Major Jenkins
¾ May 23rd, 1994
Originally published in the Dec-Jan '95 issue
of Mountain Astrologer.
Why did the ancient Mayan or pre-Maya choose
December 21st, 2012 A.D., as the end of their
Long Count calendar? This article will cover some
recent research. Scholars have known for decades
that the 13-baktun cycle of the Mayan "Long
Count" system of timekeeping was set to end
precisely on a winter solstice, and that this
system was put in place some 2300 years ago. This
amazing fact - that ancient Mesoameri- can skywatchers
were able to pinpoint a winter solstice far off
into the future - has not been dealt with by Mayanists.
And why did they choose the year 2012? One immediately
gets the impression that there is a very strange
mystery to be confronted here. I will be building
upon a clue to this mystery reported by epigrapher
Linda Schele in Maya Cosmos (1994). This article
is the natural culmination of the research relating
to the Mayan Long Count and the precession of
the equinoxes that I explored in my recent book
Tzolkin: Visionary Perspectives and Calendar Studies
(Borderlands Science and Research Foundation,
1994).
The Mayan Long Count
Just some basics to get us started. The Maya were
adept skywatchers. Their Classic Period is thought
to have lasted from 200 A.D. to 900 A.D., but
recent archeological findings are pushing back
the dawn of Mayan civilization in Mesoamerica.
Large ruin sites indicating high culture with
distinctly Mayan antecedents are being found in
the jungles of Guatemala dating back to before
the common era. And even before this, the Olmec
civilization flourished and developed the sacred
count of 260 days known as the tzolkin. The early
Maya adopted two different time keeping systems,
the "Short Count" and the Long Count.
The Short Count derives from combining the tzolkin
cycle with the solar year and the Venus cycle
of 584 days. In this way, "short" periods
of 13, 52 and 104 years are generated. Unfortunately,
we won't have occasion to dwell on the properties
of the so-called Short Count system here. The
Long Count system is somewhat more abstract, yet
is also related to certain astronomical cycles.
It is based upon nested cycles of days multiplied
at each level by that key Mayan number, twenty:
Number of Days / Term
1 / Kin (day)
20 / Uinal
360 / Tun
7200 / Katun
144000 / Baktun
Notice that the only exception to multiplying
by twenty is at the tun level, where the uinal
period is instead multiplied by 18 to make the
360-day tun. The Maya employed this counting system
to track an unbroken sequence of days from the
time it was inaugurated. The Mayan scholar Munro
Edmonson believes that the Long Count was put
in place around 355 B.C. This may be so, but the
oldest Long Count date as yet found corresponds
to 32 B.C. We find Long Count dates in the archeological
record beginning with the baktun place value and
separated by dots. For example: 6.19.19.0.0 equals
6 baktuns, 19 katuns, 19 tuns, 0 uinals and 0
days. Each baktun has 144000 days, each katun
has 7200 days, and so on. If we add up all the
values we find that 6.19.19.0.0 indicates a total
of 1007640 days have elapsed since the Zero Date
of 0.0.0.0.0. The much discussed 13-baktun cycle
is completed 1872000 days (13 baktuns) after 0.0.0.0.0.
This period of time is the so called Mayan "Great
Cycle" of the Long Count and equals 5125.36
years.
But how are we to relate this to a time frame
we can understand? How does this Long Count relate
to our Gregorian calendar? This problem of correlating
Mayan time with "western" time has occupied
Mayan scholars since the beginning. The standard
question to answer became: what does 0.0.0.0.0
(the Long Count "beginning" point) equal
in the Gregorian calendar? When this question
is answered, archeological inscriptions can be
put into their proper historical context and the
end date of the 13-baktun cycle can be calculated.
After years of considering data from varied fields
such as astronomy, ethnography, archeology and
iconography, J. Eric S. Thompson determined that
0.0.0.0.0 correponded to the Julian date 584283,
which equals August 11th, 3114 B.C. in our Gregorian
calendar. This means that the end date of 13.0.0.0.0,
some 5125 years later, is December 21st, 2012
A.D.1
The relationship between the Long Count and Short
Count has always been internally consistent (both
were tracked alongside each other in an unbroken
sequence since their conception). Now it is very
interesting to note that an aspect of the "Short
Count", namely, the sacred tzolkin count
of 260 days, is still being followed in the highlands
of Guatemala. As the Mayan scholar Munro Edmonson
shows in The Book of the Year, this last surviving
flicker of a calendar tradition some 3000 years
old supports the Thompson correlation of 584283.
Edmonson also states that the Long Count was begun
by the Maya or pre-Maya around 355 B.C., but there
is reason to believe that the Long Count system
was being perfected for at least 200 years prior
to that date.
The point of interest for these early astronomers
seems to have been the projected end date in 2012
A.D., rather than the beginning date in 3114 B.C.
Having determined the end date in 2012 (for reasons
we will come to shortly), and calling it 13.0.0.0.0,
they thus proclaimed themselves to be living in
the 6th baktun of the Great Cycle. The later Maya
certainly attributed much mythological significance
to the beginning date, relating it to the birth
of their deities, but it now seems certain that
the placement of the Long Count hinges upon its
calculated end point. Why did early Mesoamerican
skywatchers pick a date some 2300 years into the
future and, in fact, how did they pinpoint an
accurate winter solstice? With all these considerations
one begins to suspect that, for some reason, the
ancient New World astronomers were tracking precession.
The Precession
The precession of the equinoxes, also known as
the Platonic Year, is caused by the slow wobbling
of the earth's polar axis. Right now this axis
roughly points to Polaris, the "Pole Star,"
but this changes slowly over long periods of time.
The earth's wobble causes the position of the
seasonal quarters to slowly precess against the
background of stars. For example, right now, the
winter solstice position is in the constellation
of Sagittarius. But 2000 years ago it was in Capricorn.
Since then, it has precessed backward almost one
full sign. It is generally thought that the Greek
astronomer Hipparchus was the first to discover
precession around 128 B.C. Yet scholarship indicates
that more ancient Old World cultures such as the
Egyptians (see Schwaller de Lubicz's book Sacred
Science) and Babylonians also knew about the precession.
I have concluded that even cultures with simple
horizon astronomy and oral records passed down
for a hundred years or so, would notice the slow
shifting of the heavens. For example, imagine
that you lived in an environment suited for accurately
demarcated horizon astronomy. Even if this wasn't
the case, you might erect monoliths to sight the
horizon position of, most likely, the dawning
winter solstice sun. This position in relation
to background stars could be accurately preserved
in oral verse or wisdom teachings, to be passed
down for centuries. Since precession will change
this position at the rate of 1 degree every 72
years, within the relatively short time of 100
years or so, a noticeable change will have occurred.
The point of this is simple. To early cultures
attuned to the subtle movements of the sky, precession
would not have been hard to notice.2
The Maya are not generally credited with knowing
about the precession of the equinoxes. But considering
everything else we know about the amazing sophistication
of Mesoamerican astronomy, can we realistically
continue to deny them this? Many of the as yet
undeciphered hieroglyphs may ultimately describe
precessional myths. Furthermore, as I show in
my book Tzolkin: Visionary Perspectives and Calendar
Studies, the Long Count is perfectly suited for
predicting future seasonal quarters, indefinitely,
and precession is automatically accounted for.
Some of the most incredible aspects of Mayan cosmo-conception
are just now being discovered. As was the case
with the state of Egyptology in the 1870's, we
still have a lot to learn. In addition, Mayanists
like Gordon Brotherston (The Book of the Fourth
World) consider precessional knowledge among Mesoamerican
cultures to be more than likely.
The Sacred Tree
We are still trying to answer these questions:
What is so important about the winter solstice
of 2012 and, exactly how were calculations made
so accurately, considering that precession should
make them exceedingly difficult?
If we make a standard horoscope chart for December
21st, 2012 A.D., nothing very unusual appears.
In this way I was led astray in my search until
Linda Schele provided a clue in the recent book
Maya Cosmos. Probably the most exciting breakthrough
in this book is her identification of the astronomical
meaning of the Mayan Sacred Tree. Drawing from
an impressive amount of iconographic evidence,
and generously sharing the process by which she
arrived at her discovery, the Sacred Tree is found
to be none other than the crossing point of the
ecliptic with the band of the Milky Way. Indeed,
the Milky Way seems to have played an important
role in Mayan imagery. For example, an incised
bone from 8th century Tikal depicts a long sinking
canoe containing various deities. This is a picture
of the night sky and the canoe is the Milky Way,
sinking below the horizon as the night progresses,
and carrying with it deities representing the
nearby constellations. The incredible Mayan site
of Palenque is filled with Sacred Tree motifs
and references to astronomical events. In their
book Forest of Kings, Schele and Freidel suggested
that the Sacred Tree referred to the ecliptic.
Apparently that was only part of the picture,
for the Sacred Tree that Pacal ascends in death
is more than just the ecliptic, it is the sacred
doorway to the underworld. The crossing point
of Milky Way and ecliptic is this doorway and
represents the sacred source and origin. In the
following diagram of the well known sarcophagus
carving, notice that the Milky Way tree serves
as an extension of Pacal's umbilicus. The umbilicus
is a human being's entrance into life, and entrance
into death as well:

Diagram 1: Pacal and the Sacred Tree.
We may also remember at this point that the tzolkin
calendar is said to spring from the Sacred Tree.
The Sacred Tree is, in fact, at the center of
the entire corpus of Mayan Creation Myths. We
should definitely explore the nature of this astronomical
feature.
The first question that came up for me was as
follows. Since Lord (Ahau) Pacal is, by way of
divine kingship, equated with the sun, and he
is portrayed "entering" the Sacred Tree
on his famous sarcophagus lid, on what day does
the sun come around to conjunct the crossing point
of ecliptic and Milky Way? This would be an important
date. In the pre-dawn skies of this date, the
Milky Way would be seen to arch overhead from
the region of Polaris (Heart of Sky) and would
point right at where the sun rises. This (and
the corollary date 6 months later) is the only
date when the Sun/Lord could jump from the ecliptic
track and travel the Milky Way up and around the
vault of heaven to the region of Polaris, there
to enter the "Heart of Sky." It should
be mentioned that 1300 years ago, during the zenith
of Palenque's glory, Polaris was much less an
exact "Pole Star" than it is now. Schele
demonstrates that it wasn't a Pole Star that the
Maya mythologized in this regard, it was the unmarked
polar "dark region" symbolizing death
and the underworld around which everything was
observed to revolve. Life revolves around death
- a characteristically Mayan belief. The dates
on which the sun conjuncts the "Sacred Tree"
are thus very important. These dates will change
with precession. Schele doesn't pursue this line
of reasoning, however, and doesn't even mention
that these dates might be significant. If we go
back to 755 A.D., we find that the sun conjuncts
the Sacred Tree on December 3rd. I should point
out here that the Milky Way is a wide band, and
perhaps a 10-day range of dates should be considered.
To start with, however, I use the exact center
of the Milky Way band that one finds on star charts,
known as the "Galactic Equator" (not
to be confused with Galactic Center). Where the
Galactic Equator crosses the ecliptic in Sagittarius
just happens to be where the dark rift in the
Milky Way begins. This is a dark bifurcation in
the Milky Way caused by interstellar dust clouds.
To observers on earth, it appears as a dark road
which begins near the ecliptic and stretches along
the Milky Way up towards Polaris. The Maya today
are quite aware of this feature; the Quich»
Maya call it xibalba be (the "road to Xibalba")
and the Chorti Maya call it the "camino de
Santiago". In Dennis Tedlock's translation
of the Popol Vuh, we find that the ancient Maya
called it the "Black Road". The Hero
Twins Hunahpu and Xbalanque must journey down
this road to battle the Lords of Xibalba. (Tedlock
334, 35. Furthermore, what Schele has identified
as the Sacred Tree was known to the ancient Quich»
simply as "Crossroads."
This celestial feature was not marginal in ancient
Mayan thought and is still rec- ognized even today.
In terms of how this feature was mythologized,
it seems that when a planet, the sun, or the moon
entered the dark cleft of the Milky Way in Sagittarius
(which happens to be the exact center of the Milky
Way, the Galactic Equator), entrance to the underworld
road was possible, which could then take the journeyer
up to the Heart of Sky. Shamanic vision rites
were probably involved in this scenario. In the
Yucatan, underground caves were ritual places
used by shaman to journey to the underworld. Schele
explains that "Mayan mythology identifies
the Road to Xibalba as going through a cave"
(Forest of Kings, 209). Here we have a metaphorical
reference to the "dark rift" in the
Milky Way by way of its terrestrial counterpart,
a syncretism between earth and sky which is characteristic
of Mayan thinking. Above all, what is becoming
apparent from the corpus of Mayan Creation Myths
is that creation seems to have taken place at
a celestial crossroads - the crossing point of
ecliptic and Milky Way.
To clarify this ever growing picture, we should
stop here and plot out some charts. In addition
to the detailed star maps from Norton's 2000.0
Star Atlas which allowed me to pinpoint the crossing
point of Galactic Equator and ecliptic, I use
EZCosmos to plot these positions3. What I found
answers the question of why the Maya chose the
winter solstice of 2012, a problem seemingly avoided
by astronomers and Mayanists alike. While it is
true that the sun conjuncts the Sacred Tree on
December 3rd in the year 755 A.D., over the centuries
precession has caused the conjunction date to
approach the winter solstice. So, how close are
we to perfect conjunction today? Exactly when
might we expect the winter solstice sun to conjunct
the crossing point of Galactic Equator and ecliptic
- the Mayan Sacred Tree? Any astronomer will tell
you that, presently, the Milky Way crosses the
ecliptic through the constellation of Sagittarius
and this area is rich in nebulae and high density
objects. In fact, where the Milky Way crosses
the ecliptic in Sagittarius also happens to be
the direction of the Galactic Center.4
The Charts
So the quest returns to identifying why December
21st, 2012 A.D. might represent some kind of astronomical
anomoly. I'll get right to the heart of the matter.
Let's look at a few charts.

Chart 1.
Here is a full view of the sky at noon on December
21st, 2012 A.D. The band of the Milky Way can
be seen stretching from the lower right to the
upper left. The more or less vertical dotted line
indicates the Galactic Equator. The planets can
be seen tracing a roughly horizontal path through
the chart, indicating the ecliptic. The sun, quite
strikingly, is dead center in the Sacred Tree.
Let's look closer.

Chart 2.
The field is now reduced from a horizon-to-horizon
view to a field of 30 degrees. Part of the constellation
of Sagittarius can be seen in the lower left portion
of the chart. The planet in the middle-to-upper
left portion of the chart is Pluto, which rarely
travels directly along the ecliptic. The center
square near the sun is placed on the Trifid Nebula
(M20). According to the star chart I used, this
nebula is very close to the crossing point of
Galactic Equator and ecliptic. However, a small
star (4 Sgr) is even closer; it sits right on
the Galactic Equator and its declination is only
00 .08' below the ecliptic. Let's look closer
at these features.

Chart 3.
The field is now reduced to a 5-degree span, what
astrology considers to be within conjunction.
The dot to the lower right of the sun is the star
4 Sgr. Amazingly, the Sun is right on target.
We couldn't have hoped for a closer conjunction.
1 day before or after will remove the sun a noticeable
distance from the crossing point. December 21st,
2012 (13.0.0.0.0 in the Long Count) therefore
represents an extremely close conjunction of the
winter solstice sun with the crossing point of
Galactic Equator and the ecliptic, what the ancient
Maya recognized as the Sacred Tree. It is critical
to understand that the winter solstice sun rarely
conjuncts the Sacred Tree. In fact, this is an
event that has been coming to resonance very slowly
over thousands and thousands of years. What this
might mean astrologically, how this might effect
the "energy weather" on earth, must
be treated as a separate topic.
But I should at least mention in passing that
this celestial convergence appears to parallel
the accelerating pace of human civilization. It
should be noted that because precession is a very
slow process, similar astronomical alignments
will be evident on the winter solstice dates within
perhaps 5 years on either side of 2012. However,
the accuracy of the conjunction of 2012 is quite
astounding, beyond anything deemed calculable
by the ancient Maya, and serves well to represent
the perfect mid-point of the process.
Let's go back to the dawn of the Long Count and
try to reconstruct what may have been happening.
Why: Winter Solstice Sun Conjuncts The
Sacred Tree in 2012 A.D.
First, the tzolkin count originated among the
Olmec at least as early as 679 B.C. (see Edmonson's
Book of the Year). We may suspect that astronomical
observations were being made from at least that
point. The tzolkin count has been followed unbroken
since at least that time, up to the present day,
demonstrating the high premium placed by the Maya
upon continuity of tradition. In this way, star
records, horizon positions of the winter solstice
sun, and other pertinent observations could also
have been accurately preserved. As suggested above,
precession can be noticed by way of even simple
horizon astronomy in as little time as 100 to
150 years. (Hipparchus, the alleged "discoverer"
of precession among the Greeks, compared his own
observations with data collected only 170 years
before his time.) Following Edmonson, the Long
Count system may have appeared as early as 355
B.C. Part of the reason for implementing the Long
Count system, as I will show, was probably to
calculate future winter solstice dates.
We must assume that even at this early point
in Mesoamerican history, the crossing point of
ecliptic and Milky Way was understood as the "Sacred
Tree". Since the Sacred Tree concept is intrinsically
tied into the oldest Mayan Creation Myths, this
is not improbable. At the very least, the "dark
rift" was already a recognized feature. Early
skywatchers of this era (355 B.C.) would then
observe the sun to conjunct the dark ridge in
the Milky Way on or around November 18th.5 This
would be easily observed in the pre-dawn sky as
described above: the Milky Way points to the rising
sun on this date.
Over a relatively short period of time, as an
awareness of precession was emerging, this date
was seen to slowly approach winter solstice, a
critical date in its own right in early Mayan
cosmo-conception. At this point, precession and
the rate of precession was calculated, the Long
Count was perfected and inaugurated, and the appropriate
winter solstice date in 2012 A.D. was found via
the Long Count in the following way.
How: Long Count and Seasonal Quarters
Long Count katun beginnings will conjunct sequential
seasonal quarters every 1.7.0.0.0 days (194400
days). This is an easily tracked Long Count interval.
Starting with the katun beginning of 650 B.C.:
Long Count Which Quarter? Year
6.5.0.0.0 Fall 650 B.C.
7.12.0.0.0 Winter 118 B.C.
8.19.0.0.0 Spring 416 A.D.
10.6.0.0.0 Summer 948 A.D.
11.13.0.0.0 Fall 1480 A.D.
13.0.0.0.0 Winter 2012 A.D.
Note that the last date is not only a katun beginning,
but a baktun beginning as well. It is, indeed,
the end date of 2012.6
The Long Count may have been officially inaugurated
on a specific date in 355 B.C., as Edmonson suggests,
but it must have been formulated, tried, tested,
and proven before this date. This may well have
taken centuries, and the process no doubt paralleled
(and was perhaps instigated by) the discovery
of precession. The Long Count system automatically
accounts for precession in its ability to calculate
future seasonal quarters - a property which shouldn't
be underestimated.
Summary
This has been my attempt to fill a vacuum in Mayan
Studies, an answer to the why and how of the end
date of the 13-baktun cycle of the Mayan Long
Count. The solution requires a shift in how we
think about the astronomy of the Long Count end
date. The strange fact that it occurs on a winter
solstice immediately points us to possible astronomical
reasons, but they are not obvious. We also shouldn't
forget the often mentioned fact that the 13-baktun
cycle of some 5125 years is roughly 1/5th of a
precessional cycle. This in itself should have
been suggestive of a deeper mystery very early
on. Only with the recent identification of the
astronomical nature of the Sacred Tree has the
puzzle revealed its fullness. And once again we
are amazed at the sophistication and vision of
the ancient New World astronomers, the decendants
of whom still count the days and watch the skies
in the remote outbacks of Guatemala.
This essay is not contrived upon sketchy evidence.
It basically rests upon two facts:
1) the well known end date of the 13-baktun cycle
of the Mayan Long Count, which is December 21st,
2012 A.D. and
2) the astronomical situation on that day. Based
upon these two facts alone, the creators of the
Long Count knew about and calculated the rate
of precession over 2300 years ago. I can conceive
of no other conclusion. To explain this away as
"coincidence" would only obscure the
issue.
For early Mesoamerican skywatchers, the slow
approach of the winter solstice sun to the Sacred
Tree was seen as a critical process, the culmination
of which was surely worthy of being called 13.0.0.0.0,
the end of a World Age. The channel would then
be open through the winter solstice doorway, up
the Sacred Tree, the Xibalba be , to the center
of the churning heavens, the Heart of Sky.
Notes:
1Linda Schele and David Freidel, unlike most
Mayanists, continue to support the work of Floyd
Lounsbury in promoting the 584285 correlation.
This is 2 days off from the Thompson correlation
that I use. The decisive factor in supporting
the Thompson correlation of 584283 is the fact
that it corresponds with the tzolkin count still
followed in the highlands of Guatemala. To account
for this discrepency in his correlation, Lounsbury
claims that the count was shifted back two days
sometime before the conquest (not likely), thus
explaining its present placement. This means that
either correlation will give the December 21st
end date. Nevertheless, Schele and Freidel still
report that the end date is December 23rd, 2012
rather than Dec. 21st, an unfortunate faux pas
understandable only because they aren't particularly
interested in the specifics of the correlation
debate. For a detailed discussion of this topic,
refer to my book Tzolkin: Visionary Perspectives
and Calendar Studies.
2Case in point is the mysterious existence of
myths obviously describing precession in the ancient
verses of the Kalevala, the Finnish National Epic.
These myths were relayed from the earliest times
by way of singers. Many of these stories are thoroughly
magical and are filled with sky lore. The Finnish
language is not of Indo- European origin and up
until the late 19th century peasants in Finland
and northwestern Russia had little contact with
Europe. Indeed, their heritage suggests more contact
with Central Asia than Europe. Some of the Kalevala
stories describe a sacred Mill called the Sampo
(derived from sanskrit Skambha = pillar or pole)
with a "many ciphered cover". This spinning
Mill is a metaphor for a Golden Age of plenty
and the starry sky spinning around the Pole Star
(known as the Nail of the North), which in the
Far North is almost straight over head. The Mill
at some point is disturbed, its pillar being pulled
out of its peg, and a new one - a new "age"
- must be constructed. This becomes the chore
of Ilmarinen, the primeval smith. In this legend,
ancient knowledge of precession among unsophisticated
"peasants" who were nonetheless astute
skywatchers, was preserved via oral tradition
almost down to modern times.
3EZCosmos is a graphic software package that
can accurately plot and animate the positions
of planets, stars, nebula and so on, for 14,000
years. It is well suited to this research because
it accounts for precession in its positional calculations.
It also happens to be the software that Linda
Schele used to discover the astronomical meaning
of the Mayan Sacred Tree.
4 Here we briefly converge with the ideas of
Terence McKenna. In the book he co- authored with
his brother Dennis (Invisible Landscape, Seabury
Press 1975 and Harper San Francisco, 1993), Terence
suggests that the position of winter solstice
sun within 3 degrees of the Galactic Center in
the year 2012 A.D. (a "once-in-a-precessional-
cycle" event) may provide the eschatological
end point for his theory of time known as Timewave
Zero. His end date was chosen for historical reasons
and was, apparently, only later discovered to
correspond with the Mayan end date. The McKennas
point out that this unusual astronomical situation
has been noted by other writers, namely, Giorgio
de Santillana and Hertha von Dechend in Hamlet's
Mill (1969). As ACS Publication's The American
Ephemeris for the 21st Century shows, in the year
2012 the Galactic Center is at 27 Sagittarius
(within 3 of winter solstice). Thus McKenna demonstrates
that on winter solstice of 2012, Galactic Center
will be rising heliacally just before dawn, in
a way reminiscent of how the Maya observed Venus's
last morningstar appearance.
5This basically follows the "1 degree every
72 years" rule of precession. In this way,
back in 3114 B.C. the sun conjuncted the Sacred
Tree on Oct 10th, which is 72 degrees, or 1/5th
of the ecliptic from the winter solstice. The
Fall Equinox sun conjuncted the Sacred Tree about
6400 years ago (1/4th of a precessional cycle).
Ancient cultures in Mesopotamia may have recognized
this alignment, and called it a Golden Age. The
fall from this state of alignment may be responsible
for the original Fall from Paradise myth, which
filtered out to the Judaic tradition.
6The Long Count has other strange astronomical
properties. For instance, the 13- katun cycle
of 256 years was known to the Yucatec Maya as
a prophecy cycle. We see it used in the Books
of Chilam Balam. The astronomical reference here
is to conjunction cycles of Uranus and Pluto,
two of which equal 256 years. From another angle,
3 katuns equal exactly 37 synodical cycles of
Venus.

John Major Jenkins (March 4th, 1964, 9:19 p.m.,
Chicago) is a student of Mayan time. On several
trips to Central America in the late 80's, he
worked and lived with the Quich» and Tzutujil
Maya in Guatemala. Observations gathered on these
trips were published in Chicago area newspapers.
Since then he has devoted his time to studying
Mayan cosmo-conception and the mathematical and
philosophical properties of the sacred calendar.
More thought provoking ideas can be found in his
recent book Tzolkin: Visionary Perspectives and
Calendar Studies (Borderlands Science and Research
Foundation, 1994). Additional information on the
Mayan end date alignment is available by writing
