9.3 Developments in science and astronomy

Kassite Babylonia made huge strides in astronomy. They compiled star catalogs, tracked planets, and found eclipse patterns. These discoveries laid the groundwork for future astronomical advancements.

The Kassites blended science and religion in their stargazing. They saw the sky as a divine message board and linked gods to planets. This mix of math and myth shaped Mesopotamian astronomy for centuries to come.

• Enūma Anu Enlil compiled during Kassite period encompassed 70 tablets of celestial omens predicting earthly events based on astronomical phenomena (lunar eclipses, planetary movements)
• MUL.APIN originated in Kassite era cataloged constellations and provided astronomical knowledge for calendars and agriculture (heliacal risings, weather predictions)
• Venus tablet of Ammisaduqa recorded 21-year cycle of Venus appearances establishing long-term observation practices (morning star, evening star phases)
• 18-year Saros cycle discovery enabled accurate predictions of lunar and solar eclipses advancing understanding of celestial mechanics
• Sexagesimal number system refinement facilitated complex astronomical calculations and timekeeping (base-60 system)

Kassite contributions to Babylonian astronomy

• Systematization of astronomical knowledge compiled and organized older observations creating comprehensive reference works
• Mathematical astronomy improved developing accurate prediction methods for planetary positions and eclipses
• Zodiacal system expanded dividing ecliptic into 12 equal parts laying foundation for later astrological practices
• Lunar calendar refined implementing intercalation methods to align lunar months with solar year (adding extra month periodically)
• New astronomical instruments introduced including water clocks (clepsydras) for precise time measurements
• Professional class of astronomers established with scribes dedicated to celestial observations and interpretations (temple astronomers)

Astronomy and religion in Kassite Babylonia

• Celestial divination interpreted astronomical phenomena as divine messages guiding royal decisions and predicting events
• Astral deities associated gods with celestial bodies (Shamash-Sun, Sin-Moon, Ishtar-Venus)
• Temple observatories conducted astronomical observations in religious contexts combining scientific and spiritual pursuits
• Calendrical rituals timed religious ceremonies according to celestial events (New Year's festival at spring equinox)
• Horoscopy developed early forms of personal astrology linking individual fates to celestial positions at birth
• Mythological explanations integrated astronomical phenomena into religious narratives (eclipses as divine battles)

Influence of Kassite astronomy on Mesopotamia

• Neo-Assyrian astronomy adopted and expanded Kassite astronomical texts creating extensive libraries (Library of Ashurbanipal)
• Neo-Babylonian advancements further refined mathematical astronomy developing complex predictive models (System A, System B)
• Persian period developments integrated Babylonian astronomy into broader scientific traditions influencing Achaemenid scholarship
• Hellenistic astronomy transmitted Mesopotamian knowledge to Greek astronomers shaping early Western astronomical thought (Ptolemy)
• Medieval Islamic astronomy preserved and translated Babylonian astronomical texts influencing Islamic Golden Age science
• Modern astronomical terminology retains concepts and names rooted in Mesopotamian astronomy (zodiac signs, 360-degree circle)
