The first scientific revolution may have started in Mesopotamia.
In short: Long before the Renaissance, Babylonian priest-scribes were moving beyond mere observation to develop an internal logic for the universe. By treating celestial movements as mathematical problems rather than just myths, they laid the foundation for every subsequent era of Western and Eastern science.
During the 8th and 7th centuries BC, Babylonian astronomers shifted toward a new empirical approach. They began documenting their belief systems while simultaneously employing internal logic to create predictive planetary models. This transition—moving from simple recording to systematic, logical prediction—is so significant that modern scholars often categorize it as a 'scientific revolution.' This methodology was later adopted and expanded by Greek and Hellenistic astronomers.
The Babylonians were the first civilization to possess a functional theory of the planets. They utilized a unique sexagesimal (base-60) numeral system, which allowed them to calculate both incredibly large and small numbers with ease. To map the heavens, they divided the 360-degree sky into 12 zodiacal signs of 30 degrees each. Their records were so precise that they identified repeating patterns, such as the 18-year Saros cycle of lunar eclipses, which were documented in systematic astronomical diaries.
While their work was deeply tied to divination—where celestial omens were seen as powerful but avoidable messages from gods like Ea—the math remained rigorous. While many believed they relied solely on arithmetic, recent analysis of tablets dated between 350 and 50 BC reveals that they also used geometrical methods to describe the motion of Jupiter in abstract mathematical space. This sophisticated interplay of math and observation paved the way for modern astrology and global scientific astronomy.
Despite these achievements, much of their specific planetary theory remains lost. Our knowledge survives only in fragments: clay tablets containing diaries, ephemerides (tables of celestial positions), and procedure texts. One notable find is the 'ivory prism' from Nineveh, which served as a unit converter for calculating the movements of constellations.
