Excavated evidence
Archaeology
What excavation actually established at Eridu and Uruk, read from
publications this project holds — and, where the evidence stops, the exact place
it stops.
Every row below walks back through the chain
SITE → EXCAVATION → STRATIGRAPHIC CONTEXT → LEVEL/PHASE
→ DATING BASIS → DATE → PUBLICATION.
An empty link is a named gap. A date without a stated basis is not displayed at all.
Site comparisons
Each pair is compared on held evidence only. Where the two cannot
be placed on a common absolute scale, the panel says so rather than implying an age
ranking.
Chronology walkback
A modelled range is not a date. Click any model below to walk it back to
the individual measurements and contexts that fed it. Nothing is overwritten: the raw
determination, its calibration and the model output stay three separate things.
Cross-site comparison
Similarity and proposed relationship are different things, and the
database stores them differently. Every row below ends with what it does not
establish.
Known order, unknown year
Some sequences are documented well enough to know what came before
what, and not well enough to say when. That is a real state and it is shown as one.
Transcription chain
Levels read from page images, with what it took to read them. Where
the page could not be read, no transcription exists and the reason is given.
