About This Work
The Treatise on Astronomy from the Book of Han (c. 82 CE), compiled by Ban Gu, is the earliest surviving dynastic astronomical record. It documents solar and lunar eclipses, comets, planetary conjunctions, supernovae, and sunspots with dates and positions, establishing the institutional framework for over two millennia of continuous state-sponsored celestial observation in China.

Why This Matters
This text is part of the living archive of Chinese intellectual achievement — a tradition that produced systematic astronomical observation, mathematical innovation, medical frameworks still in clinical use, and engineering at continental scale, centuries before comparable developments in Europe.
The question "did ancient China have science?" misunderstands what science is. Science is not a single cultural tradition — it is the systematic observation of nature, the rigorous documentation of phenomena, the testing of ideas against evidence, and the building of knowledge across generations. By every one of these measures, the works in this catalogue are scientific. They used different conceptual frameworks — correlative rather than mechanistic, systemic rather than reductionist — but these frameworks produced real knowledge: accurate star catalogues, effective medical treatments, precise calendar computations, and technologies that transformed civilization.
