How to Read This Log
This log records how the beginner questions were separated into brief religion-related guardrails, period, civilization, object history, and legal character. The update centers concrete legal examples, other cuneiform law collections, and how such legal texts were treated at the time.

Research Instruction
- Topic: the Code of Hammurabi
- Request: explain what it is, which religion it belongs to, whether it is related to Muhammad, whether it belongs to the age of ancient civilizations, whether the object exists, how many there are, and where it is now.
- Follow-up request: change the title if religion is not the main subject; add quotations from concrete provisions, application examples, related materials, how law collections were treated at the time, and roughly five concrete examples.

Research Design
| Angle | Checked | Use in the Article |
|---|---|---|
| Religious classification | Whether it is Islamic or connected to Muhammad | Treat briefly as a guardrail against confusion |
| Period | Eighteenth century BCE, Old Babylonian period | Place it in ancient Mesopotamian history |
| Civilization | Mesopotamia | Clarify the ancient civilization context |
| Object | Louvre stele and Susa discovery | Confirm the surviving physical object |
| Legal character | 282 legal judgments and non-modern code status | Explain the gap from modern law |
| Concrete cases | Laws 5, 7-12, 48, 117, 196-199, and 229-233 | Show judging, proof, debt, status, and builder liability |
| Comparison | Ur-Nammu, Lipit-Ishtar, Eshnunna, Hittite law, and Assyrian law | Avoid isolating Hammurabi as the first law |
Source Selection
The Louvre was prioritized for the surviving object, dimensions, date, and interpretive caution. Museum and encyclopedia sources were used for period context. Yale Avalon was used as a supporting public translation for individual provisions. Britannica and CDLI were used for cuneiform law and other law collections. Encyclopaedia Iranica was used for the Susa excavation context.
Excluded Material
- Tourism pages and social media posts without clear source control.
- Simple claims that it is the oldest law in the world.
- A full comparison with later religious law.
- Direct comparison with biblical law or Mosaic law, which would require a separate comparative legal-history report.
Judgment Criteria
The article does not make religious classification the main frame. It acknowledges the divine image on the stele as royal legitimation, while centering civilization, surviving object, and legal character. The concrete examples were chosen to avoid reducing the Code to harsh punishments: procedure, contractual proof, agricultural risk, debt labor, bodily injury, and professional liability are all represented.
Future Update Triggers
- The Louvre changes its object page, room information, or display context.
- A newer standard interpretation in Old Babylonian legal studies needs to be reflected.
- The report is expanded into a comparison with other Mesopotamian legal collections.
- The report is adapted for a school-level explainer.
