Deep Time · Side by side

Two chapters, the same questions asked of both

Put two Deep Time chapters next to each other — their evidence base, the dating methods behind them, the live debates, and the questions still open.

Documented1894 – 539 BCE

Babylon

Law codes, astronomy tablets, and the mathematics of a base-60 world.

The evidence base

Law codes, astronomical diaries, administrative and legal tablets, excavated city walls and gates, and later Greek accounts written at a distance.

Royal annals, palace reliefs, the Nineveh library tablets, siege archaeology, and correspondence between kings and provincial officials.

How we know
MethodWhat it constrains
Astronomical diariesDated observation tabletsProvides absolute chronological anchors and a record of observational practice.
Legal and administrative tabletsContracts, loans, court recordsShows law in practice, which often differs from the code's stated penalties.
Excavation and reconstructionCity walls, processional way, glazed brick assemblagesDocuments the built city. Early reconstruction work mixed restoration with interpretation.
MethodWhat it constrains
Royal annals and eponym listsInscribed prisms, cylinders and year-name listsProvides a firm regnal chronology. The narrative content is official self-presentation.
Relief iconographyCarved palace wall panelsShows equipment and tactics as the court wished them seen.
Conflict archaeologySiege ramps, arrowheads, destruction deposits and mass gravesIndependently tests the annals. Where both survive, they often agree on the event and disagree on the outcome.
Where specialists disagree
  • Was the Code of Hammurabi enforced law or royal propaganda?

    Court records rarely cite it, which is the core of the argument.

  • Did the Hanging Gardens exist, and where?

    No Babylonian text describes them; one serious proposal relocates them to Nineveh.

  • How large were Assyrian armies and deportations?

    The annals give round numbers with propagandistic function; settlement archaeology suggests lower figures.

  • Why did the empire fall so quickly?

    Overextension, civil war, coalition attack and climate stress are all argued.

Still open
  • How much of the city remains unexcavated beneath the water table?
  • How were astronomical records transmitted to later traditions?
  • What was the actual reach of royal law across the countryside?
  • How much of the Nineveh collection is still unpublished or lost?
  • What was provincial life like away from the palace record?
  • How much did drought contribute to the final collapse?
