Okay so this picture may look like just a bunch of doodles on a piece of clay, but it actually is hieroglyphs from four ancient Mayan codices that predict with surprising accuracy the 1991 Solar Eclipse. The Mayan astronomers were able to predict within a day, the time of the 1991 solar eclipse. Keep in mind that all of these predictions took place before the 16th century, so that is pretty impressive. The calendar was found to date the eclipse as being either on the 11th or the 12th and however many centuries later in 1991, the eclipse happened on July 12. That’s crazy. It seems like people today tend to assume that all of the stuff we have discovered about the path of the sun and stars has happened in the past couple hundred years, but the people of ancient times were killing it at the astronomy game before we even figured out what electricity was. These guys didn’t have any computers or fancy telescopes, but still managed to figure out when the moon is going to block the sun 500+ years before it actually happens. Serious props to the Mayans.
