[Aztlan] E-Groups

[Robert Hall]

     Pursuing the thread of nadir passage and E-groups I am providing below for the listeros' consideration a paragraph from a larger manuscript paper that I have been circulating among colleagues for comment:
 
    "As they were originally calculated, using the now abandoned Spinden correlation, dates associated with the Uaxactun Group E stelae were not found to relate to any special seasonal station of the sun, though such a relationship might have expected for architecture thought to have solar orientations. Later reductions of the Uaxactun dates using GMT constants generated dates in January and February that were also not recognized at the time as having any special solar significance. The Uaxactun dates, using the 584283 constant, are February 1, 357 AD, for the LC date 8.16.0.0.0 on Stelae 18 and 19 and January 28, 495 AD, for the date 9.3.0.0.0 on Stela 20. Each LC date marks a katun-ending. These dates turn out to actually be quite significant. Uaxactun has a latitude of 17.40 degrees north. . . . At that latitude the sun makes its first nadir passage on January 31. The dates on the Group E stelae are the only katun-ending dates that ever had been
 or that ever would be so close to a day of first nadir passage of the sun for the latitude of Uaxactun during the entire course of Maya civilization. One must now consider that this could have had considerable significance for the Maya of this site, because the sun’s annual first nadir passage was possibly also considered by the authors of these stelae to be an anniversary of the Maya Creation. This assumes that the nadir-passage proximity of the date for the ChortÍ celebration of the Creation (discussed earlier) reflects some once more broadly distributed reality. That reality would be a Creation not tied to the 4 Ahau 8 Cumku era base of the Long Count but to an earlier calendar."

Here is an interesting nadir perspective from Susan Milbrath as noted in her
book “Star Gods of the Maya.”

“Just as the first solar zenith is important because it coincides
approximately with the onset of the rainy season in Mesoamerica, a complimentary
event known as the second solar nadir coincides with the beginning of the dry
season. For example, at the latitude of Chichen Itza (20 degrees 41 minutes) the
sun reaches its solar nadir on November 22 and on January 21 in the Gregorian
calendar. Further south, at 18 degrees N latitude, the second solar nadir falls
on January 30. The contemporary Quiche Maya determine the date of the nadir by
watching the full moon pass overhead at midnight.”
