Section I Summary presents findings that indicate that the designers of Teotihuacan were Mayan. Identification was made possible by isolating the unit of measure used by the constructors. This permitted comparison of redundant dimensions in the architecture, which led to deduction of the mathematical capabilities of the designers. Astronomical counts form a chronological model of the solar system.

1.) A unit of linear measure was found: the Standard Teotihuacan Unit (STU) of 1.0594(6) meters (41.7111 English inches.) More than 7,000 conversions were made of dimensions in the “Ceremonial” Zone: 1,924,582 square meters (1,714,608 square STU = 756 X 2,268 STU.) Rounding of dimensions of stone structures were held to less than the official photogrammetric aerial map restoration (accuracy, scale of 1:2000, is +/-50 centimeters (see Appendix 3.) Many repeating dimensions are factored by prime numbers 2, 3, 5 and 7.

2.) Dimensions of Teotihuacan appear in the Mayan Dresden Codex, pp. 71 to 73, in the form of 13 counts, corrections every 21,600 days (three Katuns) to obtain 59-year Jupiter/Saturn conjunction counts as multiples of 21,546 days, a Mayan approximation. To achieve precision Mayans used integral numbers, later corrected by adding or subtracting integral days after long-term lapses.

3.) The design triangle of Teotihuacan is formed by the two largest pyramids and the Great Avenue. This triangle defines two 378-day Saturn orbits as 756 STU, the number of 399-day Jupiter orbits for the planet to circle one-third of the Zodiac as 720 STU; and the base leg 231 STU, the number of Katuns to reach the eleventh elapsed count of 400 Saturns of 151,200 days between zero reference in 3,114

B.C. and the 4,400th Saturn in 1,441 A.D. The twelfth and last date was in May of 1,855 A.D. for 4,800 Saturn orbits (uncorrected.)

4.) The “Ceremonial” Zone presents (north/south) the 13-Katun count 93,600 days, encoded twice as “936 STU.” Also shown is a Mayan Oxlahkatun of 1,872,000 days encoded as “1,872 STU.” Distances for Mercury, Venus and Mars orbital counts are given in STU.


5.) In three dimensions the Zone registers volumes in cubic STU that I have named “Numerical Arks.” The volume of this integral numerical box “contains” Saturn synodic orbits, Jupiter synodic orbits and Jupiter/Saturn conjunctions of 7,182 days (one Katun minus 18 days.) “Ark” volume of height 57 STU can be factored to give the reduced scaled area of an earth sphere, the synodic orbital time of the moon and the number of visible Jupiter/Saturn conjunction counts (every third conjunction.)

6.) Painted murals exhibit Mayan solar eclipse day-counts (Dresden Codex.) On factoring the total count by the Jupiter number 720 and the synodic orbit of Mercury of 117 days (Dresden Codex) the mural renders the same precision lunar orbit given by the Dresden Codex and by stone glyphs carved at Palenque’s Palace: 29.5308642 days.

7.) Mayan Long Counts that give anniversary dates for twelve sets of 400 Saturns (multiples of 151,200 days = are the overall Teotihuacan design basis, that also rests on 378 STU, one side of the “Citadel,” that we believe was a “Great Quadrangle of Saturn.”

8.) Dating at Teotihuacan is proposed, based on registers of 400-Saturn anniversaries at Copán and Palenque (631 A.D.) and at Edzna recorded in 1,027 A.D. (see Fig.5, pp.16, Section I.)

9.) This Summary proposes significant new Mayan dates (Fig.5,) importance of the number “9” (Fig.12) and illustrations of the corrected Mayan Zodiac, pp. 23-24, Paris Codex (see Figs. 7 & 10.)
