Researchers have cracked the code to accurately predicting Maya eclipse tables. The discovery has shed new light on the sophisticated astronomical knowledge of the ancient civilization.
The Dresden Codex, one of only four surviving Maya texts, contains a table of eclipses that was initially thought to be created solely for this purpose. However, researchers John Justeson and Justin Lowry have found that the table evolved from earlier lunar month tables. The code, which dates back to the 11th or 12th century, includes a mechanism to ensure accuracy over a long period.
The team used mathematical modeling to compare the predicted eclipse dates with historical records from NASA. They discovered that the Maya had a sophisticated understanding of astronomy and developed a system of adjustments to maintain accurate calculations. The adjustments were made based on empirical observations over time, indicating that the Maya did not simply calculate their predictions but also relied on observational data.
The researchers found that the codex's tables used a series of overlapping calculations, with the tables being restarted at two specific points before the previous one ended. This approach allowed for more accurate predictions and ensured that the calendar remained accurate over time.
This discovery highlights the impressive knowledge and understanding of astronomy possessed by the Maya civilization. The team's work demonstrates that true science is based on empirical observations, constant revision of expectations, and a deep understanding of planetary bodies. What was previously thought to be a simple table for predicting eclipses turned out to be a complex system that relied on observation, calculation, and adjustment.
The study's findings have implications for our understanding of ancient civilizations and the sophistication of their knowledge systems. The Maya calendar remains an important example of the ingenuity and skill of human astronomers throughout history.
