What is Astrotheology?

Excerpted from The 2010 Astrotheology Calendar

...In order to give meaning to and pass along knowledge about these entities and elements, the ancients personified and attached colorful stories to them. They also incorporated this ancient astrotheology and nature-worshipping religion into their daily lives, and entire cultures were built upon them, such as the Egyptian, but also the Greek and Roman to a large extent.

Thus, in ancient times sundry stories were passed on from one generation to the next, instructing them about the natural world and guiding them when to plant and when to harvest food, as one important example. Converting natural phenomena into myth was thus an easy way to relay the cycles of the sun, moon, planets, constellations, etc., onto later generations, enabling them to keep time.
