Begin with the source’s own compact description: “1640s BC” is decade. The dossier treats that line as a proposition to test through 1640s and decade, not as a finished interpretation.
Why this record matters
The phrase “decade” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 3, 2025. The linked authority identifier is Q2851880. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1649, 1640, 1650 and 1622.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
