So here it is I am a mcguyver at heart, And Part of this idealogy is just finding things out. Does anyone have Any Idea about the methodology's of our ancenstors in respect to this forum's topic ( Science ie. discovery of truth ) To no avail have I found exactly how the mayans were able to predict astronomical phenomena( atleast to them ) nor have I found a reasoning for the predictions of eclipses they are so whole heartedly reported to have graphed. I do not believe that they were able to predict the eclipse's so precisely without the aide of a sundial so let me start there with the ideas of how they counted time. I wish to especially know of any calculation of time based on fixed position to constellations at night. Thank you and by the way I am working on such a map or graph of the relationship of constellations to time to position on the planet. Thanks for your help.
