How were people able to predict eclipses in ancient times?
Ancient astronomers were able to predict eclipses, even though they did not have as much knowledge as we do today. Their methods were based on centuries of observing the sky, numerical cycles and very precise records.
Although the Egyptians had a highly advanced calendar, they left hardly any written records of solar eclipses. This was probably because they considered them to be a sign of bad luck, so they avoided talking about them. Their knowledge was based more on observation and mythology than on mathematical models for predicting them.
The Babylonians were the most accurate predictors of eclipses before the Greeks. They based their predictions on centuries of observing the sky and on highly detailed records on clay tablets. This is how they discovered the Saros cycle (which states that eclipses recur every 18 years, 11 days and 8 hours), showing that eclipses recur approximately every 18 years. This enabled them to foresee when an eclipse might occur, although they also interpreted them as omens sent by the gods.
The Maya (250–900 AD) developed a highly accurate system of astronomy based on calculations, calendars and lunar cycles. They carefully observed the movements of the Sun and the Moon and used a complex calendar system to predict eclipses. The Dresden Codex contains tables listing hundreds of lunar cycles, which enabled them to achieve a level of accuracy comparable to that of modern methods.
