In 2014, the first and last pages of the Serpent Calendar, was what I thought I had

solved completely. Especially with the One-IMIX in the first column, together with

the two KIMI’s {Death} which appeared in columns 45 and 46. One IMIX was dated

for the Maya Calendar system

solved completely. Especially with the One-IMIX in the first column, together with

the two KIMI’s {Death} which appeared in columns 45 and 46. One IMIX was dated

for the Maya Calendar system

The dates were pre-dated to Diego de Landa’s manuscripts dated from 1549 to-1579.

In 1978, Williams Gates published a Dover edition of his translation in a chapter

called “Yucatan,” with notes which included his note about the “common 52-year

cycle” of the Mesoamerican calendars, referred to by de Landa.

Gates also inferred de Landa made no mention of a 30-day calendar month, even

though it was necessary to use 30-days since the year was once 360-days within

each year of 52 weeks. [Gates, (1978,j Sec. XXXIV, 59)

each year of 52 weeks. [Gates, (1978,j Sec. XXXIV, 59)

The daily difference when the 5.24 days were added made such a small change

per day that the number of weeks stayed the same. During a year the difference

was only 0.015 of a degree per day.

per day that the number of weeks stayed the same. During a year the difference

was only 0.015 of a degree per day.

So where did I go wrong? Stating that a 52-year computation is wrong is one thing,

but proving it is another. And apparently, I was unable to make a strong enough

statement with so little information. So the thing to do next is: go the Floyd L

ounsbury’s original article and find the “if’s” and the “maybe’s,” especially, when

there is a strong “NO” in his proposal.

Floyd left the following statement for all students to mull over and experiment with

since he knew there was no verification from the Maya corpus itself. He threw in

the 52-years, in spite of the astronomy and the 350-year that he agreed with. T

hen,he adjusted the figures that could not or would not fit the formulae he decided upon.

“The Maya left no treatises or mathematical or astronomical methods or theories.

There is no posing of a problem, proof of a therem, or statement of an algorithem----none

of trhe usual kinds of souce material for the history of science, Their writing system, if

not actually prohibitive of such disquisitions was at least conductive to brevity in the

extreme. What they left are the various end products of the application of their methods.

It is up to the students to decipher what the problems were and how they have been the

methods employed in their solution…” ”...It can hardly take the form of a history of

Maya mathematics, calendars, and astronomy.”

In short, Floyd Lounsbury himself was the student he inferred in the above quotation.

The data that he compiled seemed to fit, except that he did not understand how the

horizontal Serpent Calendar of the Madrid Codex used the vertical Trecena

as 4 X 3 units, plus One.= 13 units.

The 52-week horizontal calendar in the Madrid Codex is only a workday calendar.

They are equal to our workday calendars which leave out Saturdays and Sundays.

Those two days are for personal or civil activities that cannot be accomplished

during:the weekends.

The only way the Serpent Calendar will mesh with the following 4-year unit, is

when the glyphs : BEN, ET’ZNAB, AKBAL and LAMAT, in that order, are

placed in the first row of the empty cartouches.

IK: Spring time Slash and Burning a clearing for the milpas

MANIK: Summer time Planting and caring for the milpa maize growth

EB: Autumn time Preparing for the Harvest and sttorage or sale of the Maize

CAVAN: Winter time, preparing for thanks to god and his/her helpers and for civil celebrations.

Each if the four horizontal years must mesh with the vertical year. The best way

to understand the horizontal version, is to number the beginning of each 20-day

unit, separate each 20-day unit, by cutting them apart; then fit them back together

according to the original page drawings; noting the way each column was drawn.

One can then see better the sequences needed for milpa care to regenerate the necessary

soil nutrients for future harvests in the same plot of ground. Then the other two

4-year vertical units are related to two other milpas to be used following the same

cycle so each plot has enough nutrients for a good harvest.

If you are not farmers, or come from a 4-H family, the above sequence for

three plots of land per household may seem like overworking the system.

However, it is a very precise procedure to regenerate the necessary nutrients

from what is a very thin layer of soil on top of bare rock.
