The Chakana emblem on the Tello-Obelisk at Chavin de Huantar guided my astronomical reconstruction of the Andean cross. Looking out for a simpler shape of the same astronomical relevance I discovered a pleasing solution, here given in the form of a numerical fable.
The Chakana plaza of Sipan was a fairly large square, the corners marked with fires burning on poles, Four stairways lead to a lower square, and in the center was a still lower circle.
Here are the numbers. The large square had been subdivided into six by six small squares. The fire poles were placed in the centers of the small corner squares. Between them, stairways were dug into the ground, each covering 2 small squares. Then a wider square was dug into the ground, covering the 4 by 4 inner small squares of the grid. The stairways and the lower square yielded the Andean cross, periphery 24 units, area 24 square units. In the center of the lower square a circle was dug into the deeper ground, lowest level of the sanctuary, radius 1 unit.
A Sipan spider string had 45 knots. The calendar string was 45 fingers long (85.5 cm) and the measuring string 45 palms (342 cm). For the Chanaka plaza and sanctuary a mini string was used, one knot for one day. A small square of the grid measured 93 by 93 mini spiders, the entire grid 558 by 558 mini spiders. The periphery of the Chakana pattern represented 275 years (mistake one point six days on the entire period of 100,440 days). The circumference of the circle represented 72 years (mistake two point three days on the entire period), six time the sacred period of 12 years. And the diagonal distance of the fire poles represented 81 years (mistake seven point eight days on the entire period).
The Chakana sanctuary celebrated the mythic union of the earth goddess Pachamama and the sky above.
