To the Jews, solar eclipses meant that the moon was passing between the sun and the earth, thereby blocking the suns light. Notwithstanding the physical explanation of a solar eclipse, there is also spiritual significance to it: At the time when the sun is eclipsed, it is an unfavorable period for the world. A parable: This can be compared to a human king who made a feast for his subjects, and placed a lantern before them.
In 2013, researchers found evidence that ancient Maya could accurately predict solar eclipses. An astronomical calendar from the 11th or 12th century predicted an eclipse that took place on 11 July, 1991. Solar eclipses were known as chi' ibal kin, or 'to eat the sun'. What they understood or believed about eclipses is unknown, however, with missionaries destroying almost all the written records in the 1600s.
