The registry kills Demotic

Status: Already answered

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Demotic — the everyday Egyptian script with a thousand-year notarial tradition behind it — stops being used for contracts early in Roman rule, and the standard picture blames a slow decline of Egyptian literacy. This conjecture joins the disappearance instead to an enforcement rule: Roman administration channelled property documents through Greek-language record offices, and an instrument that could not be processed there was legally dead paper regardless of who could read it. If enforceability rather than culture was the mechanism, the decline should be a cliff, not a slope — Demotic legal instruments collapsing within about one generation of the registration regime — while Demotic in genres that never needed enforcement (religious, literary, epistolary) persists for centuries. If this holds, a single administrative rule killed a legal language, and apparent 'language death' in documentary records generally must be re-read as enforceability death.

Prediction clause (verbatim)

Primary clause: in papyri.info, the count of dated Demotic legal instruments falls by at least 80% from the period 30 BCE-14 CE to 14-68 CE, while dated Demotic non-legal texts fall by less than 40% over the same span (the differential is the test). Secondary clause: the residual post-cliff Demotic legal texts cluster in temple-adjacent transaction types least dependent on state enforcement.

Kill-dataset (verbatim)

papyri.info, which includes the Demotic corpus alongside Greek documents and supports the language-by-genre-by-date counts required.

Novelty / leakage triage

already answered in the literature

The enforceability explanation is the published account: Lewis's 'The Demise of the Demotic Document: When and Why' (JEA 79, 1993) and subsequent grapheion scholarship attribute the rapid collapse of Demotic legal instruments to Roman registration/administrative policy rather than literacy decline, with non-legal Demotic persisting.
