Maya-Astronomy encompasses the extensive knowledge and observations of celestial bodies by the Maya Civilization. The Maya developed one of the most sophisticated systems for tracking time and understanding celestial events in the pre-Columbian Americas:
History and Development
- The roots of Maya-Astronomy can be traced back to the Preclassic period (2000 BC to 250 AD), where early Maya societies began observing the sky for agricultural and ceremonial purposes.
- By the Classic period (250-900 AD), the Maya had refined their astronomical knowledge, which was integral to their religious practices, agriculture, and political structure. This period saw the construction of observatories like the El Caracol in Chichen Itza.
- The Postclassic period (900-1521 AD) witnessed further developments, particularly in the synchronization of the Maya Calendar with astronomical cycles.
Key Astronomical Achievements
- Venus Cycle: The Maya tracked the cycles of Venus with great precision, recognizing its 584-day cycle. They associated Venus with war and used its cycles to plan military campaigns.
- Eclipses: They predicted solar and lunar eclipses using a 260-day calendar known as the Tzolk'in and a 365-day solar calendar called the Haab. Their records, like the Dresden Codex, contain eclipse tables.
- Constellations and Star Lore: The Maya had their own constellations, with many stars having specific names and stories. They observed the Pleiades, known to them as "Tianquiztli" or "marketplace," to mark the beginning of the agricultural year.
- Alignment of Structures: Many Maya structures were aligned with astronomical phenomena. For instance, the pyramid at Chichen Itza aligns with the setting sun during the equinoxes, creating the illusion of a serpent descending the pyramid's steps.
Tools and Methods
- The Maya used observational methods, often employing simple instruments like the Zenith Tube to track the sun's zenith passage, which helped in determining the exact dates of the solar year.
- They developed mathematical systems and used their Maya Numerals to record long counts of time, which were crucial for astronomical calculations.
Cultural Significance
- Astronomy was deeply intertwined with Maya religion and cosmology. Celestial events were seen as omens or messages from the gods, influencing everything from farming practices to royal ceremonies.
- The Maya Cosmology described the universe as a layered structure, with the heavens above and the underworld below, and the earth in between, all connected by the World Tree or Ceiba Tree.
