Do Dresden Serpent numbers hold clues to correlation constant? The 8 "Serpent Numbers" on pages 61-62 of the Dresden codex are displayed in four interleaved pairs, counted from a base date 19.16.3.16.14.11.4 9 K'an 12 K'ayab, more than 4 pictuns earlier, to dates in the 9th or 10th baktun. Four of these, one from each pair (which seems a significant fact) show moon ages which would be correct for a first appearance of new moon, IF we use the correlation constant 584283 (not 584285). Since we do not know that these dates are supposed to refer to new moons, this is simply an intriguing fact. Notice that if we use correlation constant 584285, the moon ages will be too far past new moon for this to be significant (3.3 to 3.8 days for these first four dates). (While I have followed the debates on the correlation constant, and believe I understand them at least mostly, I hope colleagues will forgive me if I am not an active partisan of either of these two correlation constants. I am providing this suggestion regarding the Dresden Serpent Numbers merely as a curiosity, in the hopes others can make progress with it.) The calculations four four dates (numbers 1,3,5,7) are: +4.6.0.13.15.1 -> 9.17.8.8.5 3 Chicchan 18 Xul Moon age 1.3 +4.6.10.9.10.1 -> 10.7.4.3.5 3 Chicchan 13 Yaxk'in Moon age 1.3 +4.6.11.10.7.2 -> 10.8.5.0.6 3 Cimi 14 K'ayab Moon age 1.5 +4.6.1.9.15.0 -> 9.18.4.8.4 3 K'an 17 Uo Moon age 1.8 The other four (dates 2,4,6,8): +4.6.14.11.3.1 -> 10.11.5.14.5 3 Chicchan 13 Pax Moon age 27.8 +4.6.1.11.5.0 -> 9.18.5.16.4 3 K'an 12 Yax Moon age 19.8 +4.6.7.12.4.10 -> 10.4.6.15.14 3 Ix 7 Pax Moon age 12.2 +4.6.9.15.12.19 -> 10.6.10.6.3 13 Ak'bal 1 K'ank'in Moon age 10.0 The first four are also included among the six, the last digit of whose 4-Pictun distance number is 0, 1, or 2 (rather than 10 or 19). Could this be an adjustment mechanism for small decimal or fractional values by using large numbers? The last two serpent numbers, on Dresden page 69, do not have this property: 9.16.8.5.12 4 Eb 5 Ch'en Moon 150 degrees ahead of sun 9.17.15.6.14 9 Ix 12 Zip Moon 120 degrees ahead of sun Notice that the eighth, ninth, and tenth of these dates are the only ones in the set of 10 which do not have "3" as the Tzolk'in number, and they all have Moon ages somewhat short of full moon. A set of astronomical graphs for these 10 dates, displaying the motion of the moon and planets on the ecliptic versus time during a twenty-day period surrounding each of the dates, is available by mail. (The set also includes two graphs of the date which has been suggested recently in National Geographic as the beginning of the Chinese calendar, when "the five planets were lined up like pearls" in Pegasus, just before new moon the beginning of Spring.) It can be obtained by sending \$1 and either a stick-on address label or a self-addressed ordinary #10 envelope (business letter size) to: Ecological Linguistics P.O. Box 15156 Washington, D.C., 20003. Other planetary properties of the 10 dates, which may or may not be significant, here just for information: ------- Date 1 Jupiter just past conjunction with the sun, Mercury rising as morning star Only Saturn far away from sun, around 180 degrees (in retrograde) Date 3 Mercury around maximum elongation as morning star Venus is morning star Date 5 Mercury beginning to fall as evening star Venus and Mars in conjunction as morning stars Date 7 Mercury around maximum elongation as evening star Venus near conjunction with Mercury ------- Date 2 (Saturn around 145 degrees) Date 4 Venus in conjunction with sun (to emerge as evening star) (Saturn and Mars less than 50 degrees away from sun) Date 6 Mercury and Venus nearing maxima as morning stars Mars near conjunction with Mercury (Only Saturn far away from sun, around 260 degrees) Date 8 Mercury at maximum as morning star Venus near maximum as evening star Mars and Jupiter within 50 degrees of sun (Saturn around 110 degrees away from sun) ------- Date 9 Mercury emerging from conjunction, as evening star Mars and (nearly) Jupiter within 50 degrees of sun (Saturn far from sun, around 240 degrees) Date 10 Both Mercury and Venus in conjunction with sun, Mercury to emerge as evening, Venus as morning star (Saturn about 40 degrees from sun, Mars 250, Jupiter 270) Best wishes for your solving some part of this puzzle!
