How did ancient cultures predict events like solar eclipses?

    They figured out the repeating patterns of the moon’s revolution around the earth, and knew that if the sun was going to be in the sky at a certain time of day when the moon was going to be in the vicinity to block it partially or entirely, that there would be a solar eclipse. Basically, they had to have a good understanding of geometry (to know the angle at which you would look up to find the moon/sun) and an efficient, accurate calendar (to know when it was going to be at which altitude).
