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.

You might want to look up "Saros Cycle".

Re:Methodologies

http://wikipedia.org/wiki/Saros_Cycle OMG that is awsome. This is helping me on my mapping project to which yesterday I established a method for calculating the "azimuth" I believe they call It (for height relative to the horizon, or sea level( depending on the case))
I have a seasonal clock based onthe constellations for any of you who may be interested.

Oh and this is awsome to http://en.wikipedia.org/wiki/Category:Time_in_astronomy
Good looking out man.

Ancient astronomers were very good at observational astronomy. They built many edifices apparently designed for that purpose. Unfortunately, they were mostly tools of religious authorities in their cultures.
