All about the ancient tribes
Maya calendars, mythology, and astrology were all incorporated into an unified set of religious beliefs and practices. The Maya were able to forecast solar and lunar eclipses, the cycles of the planet Venus, and the motions of the constellations by careful observation of the sky and the use of calendars.
Ancient Mayan Astronomy. Their highly exact calculations in astronomy and their advanced mathematics were immersed in religion and omens, and their priests were able to detect the will of the gods behind the occurrences of natural events using these calculations.
Maya culture and the sky above it. The Maya had the belief that the Earth was the permanent and unmovable center of everything in the universe. It was believed that the sun, moons, stars, and planets were gods, and that the movements of these celestial bodies represented the gods journeying between Earth, the underworld, and other locations in the cosmos.
Mayan Astronomy and the Stars The stars travel across the sky in the same way as the planets do; but, unlike the planets, they do not change their positions in relation to one another. The Maya placed a lower priority on the stars in their mythology than they did on the sun, the moon, Venus, and the other planets.
According to Mayan beliefs, all humans died and went to the underworld, with the exception of those who died during childbirth or during a sacrifice. The Maya attached a great deal of significance to astronomy, as evidenced by the fact that the majority of their monumental pyramids and temples were designed to correspond to the motion of various heavenly bodies.
