Review Questions

• How did Babylonian astronomy influence their agricultural practices and societal organization?
  • Babylonian astronomy played a key role in agriculture by enabling the prediction of seasonal changes through observations of celestial bodies. By understanding lunar cycles and planetary movements, they could determine optimal planting and harvesting times. This knowledge was essential for food production and helped organize society around agricultural calendars and festivals tied to celestial events.
• In what ways did ancient Babylonian astronomical observations contribute to the development of mathematical concepts still used today?
  • The Babylonians' use of a sexagesimal (base-60) system laid foundational principles for modern mathematics and astronomy. Their ability to measure time with precision—such as dividing the day into 24 hours—stemmed from their astronomical calculations. This mathematical approach allowed them to make accurate predictions about celestial events and influenced future astronomical models across various cultures.
• Evaluate the significance of astrology in Babylonian culture alongside their advancements in astronomy.
