The Aztec Astronomers Who Tracked Venus and Predicted the End of the World

Long before the Spanish arrived, the Mexica of Tenochtitlan were expert skywatchers. They built the Templo Mayor aligned to the sun's path, carved the great Sun Stone to track cosmic cycles, and feared the moments when Venus disappeared from the sky—believing it signaled the possible end of the world. In this episode, Lucas and Luna explore the astronomical knowledge of the Aztec priest-scientists: how they observed the movements of Venus, the Pleiades, and the sun; how they interwove astronomy with agriculture, warfare, and human sacrifice; and why the Spanish chroniclers like Bernardino de Sahagún recorded their celestial lore with awe. We meet the tonalpouhque (day-keepers) who read the 260-day ritual calendar, and learn how the 52-year 'New Fire' ceremony reset the cosmos. This is the science behind the myths, showing a civilization that understood the heavens as deeply as any in the ancient world. #AztecAstronomy #Tenochtitlan #Venus #NewFireCeremony #Tonalpouhque #BernardinoDeSahagun #FlorentineCodex #TemploMayor #SunStone #Pleiades #Mesoamerica #Mexica #CalendarRound #Archaeoastronomy #History #FexingoHistory #AztecScience #PreColumbian Keep every episode free: buymeacoffee.com/fexingo
