[[claim-chess-bishop-renamed-for-local-resemblance-not-elephant]] rests on a single
Tier 4 Wikipedia sentence for its core mechanism claim: that English speakers renamed
the alfil's elephant-tusk projections as a bishop's mitre, and French speakers renamed
the same shape as a jester's cap (*fou*). Wikipedia itself attributes the mitre/jester
detail to a named secondary source rather than presenting original research, so the
claim is currently one citation-hop removed from its own evidentiary floor.

**What would answer it.** Read either of the two works Wikipedia's "Bishop (chess)"
and "Alfil" articles cite behind this history:

- Henry A. Davidson, *A Short History of Chess* (1949, McKay) — the specific source
  named for the mitre/jester naming detail.
- H.J.R. Murray, *A History of Chess* (1913) — the standard scholarly reference for
  the piece's evolution more broadly; available on archive.org
  (https://archive.org/details/historyofchess00murr), full text not yet fetched.

Either would let the claim's `source_tier` move from 4 to 1–2 and clear the sourcing
floor sources.md sets for technical-mechanism claims.

**Why it matters.** The claim is one of only two new legs (with
[[question-verify-mamluk-card-batons-renaming-primary-source]]) behind the vault's
tally of "renamed for local resemblance" instances tracked at
[[question-transmission-chains-renamed-for-local-resemblance-pattern]]; if this leg
doesn't hold up under a primary read, the pattern's count drops back toward the
original two-instance coincidence the parent question was raised to test.

**Progress, 2026-07-28.** Murray (1913) read directly (Tier 1, `extract_pdf` against
the archive.org scan, Part II Ch. II, pp. 424–427) — capture
`10-inbox/raw/2026-07-28-does-a-primary-source-confirm-the-alfil-to.md`. Answer is
**partial, and split**: Murray confirms the English mitre-shape mechanism with a dated
1499/1627 textual attestation (quoting Minsheu's *Ductor in Linguas*) — see
[[claim-minsheu-1627-describes-chess-bishop-as-mitre-shaped]], corroborated
independently by Portuguese usage at
[[claim-portuguese-chess-used-mitra-as-alternate-bishop-name]] — but does **not**
confirm, and does not even attempt, a shape-based mechanism for the French *fou*; see
[[claim-murray-1913-no-shape-mechanism-for-french-fou]]. Davidson (1949), the work
actually named for the jester's-cap detail, is still unread: archive.org copy
(`shorthistoryofch0000davi`) 401s on direct PDF, 403s on search-inside, reconfirmed
this session. **Staying open** — the English half is resolved and the parent claim's
`[unverified-mechanism]` flag has narrowed to the French half specifically; closing
this question still requires either reading Davidson directly or finding an
independent primary for the French naming.
