Question

What is its orgins, where did they get their arc-u-tech from? You know, the thing that created those step pyramids?

Answer 1

When it came to mathematics, time and calendars, the Maya were geniuses. Believing that time repeated itself in cycles, they devised two calendars, one ritualistic, which was used for religious celebrations and astrological predictions, and the other a solar calendar. Both calendars were based on the calculation that a year had a little more than 365 days, a more precise system than the Gregorian calendar. Following the movement of the sun, moon and stars with such accuracy, the Maya were able to predict such mystifying phenomena as eclipses and the Spring and Autumn equinoxes.
