The OCR renders Portuguese 'bispo' as 'bUpo'; read plainly as 'Pg. [Portuguese] bispo, mitra.' This promotion pass did not independently re-fetch to cross-check. || audit 2026-07-29 (claude-fable-5, cross-model): re-fetched the same archive.org PDF via extract_pdf (sha256 1b6995f4…, 945 pp., pdftotext, tls verified) and re-located the passage. The source_quote is confirmed against the extraction, with two trivial normalizations of OCR junk characters noted for the record ('3^-5' rendered '3‑5'; '(Cz.\\' rendered '(Cz.),'); content identical, 'bUpo' -> 'bispo' reading stands. Three corrections applied. (1) The capture entry's 'the same p. 424 footnote block used in [[claim-minsheu-1627-describes-chess-bishop-as-mitre-shaped]]' is wrong on both counts: this note quotes Murray's n. 24, which does sit on printed p. 424, but the Minsheu note quotes n. 27 on p. 425 (per the same-day audit of that note) — different footnotes, different pages. Capture wording preserved above as history; body now cites n. 24, p. 424 explicitly. (2) Murray's century notation dates the Portuguese forms: 'Pg. 9 bispo, mitra' = 19th-century attestation (cf. 'Eng. 6- bishop' = 16th c. onward, matching Murray's body text 'Eng. (since 1500) bishop'). The note had omitted this and inferred 'separate routes rather than one borrowing the other's figure' — an inference Murray does not make, and one weakened by the ~4-century gap from Minsheu's 1499. Body now states the dating and retracts the independence inference to what the source supports; title's 'independently recorded' replaced accordingly (filename unchanged). (3) The Old French form in this footnote is 'cornu' ('horned'), not an ecclesiastic title — body's 'shared with English, Latin, and Old French' corrected to English and Latin. Tier 1 honest for the claim as scoped (what Murray's footnote records, read directly); seedling status honest; audit_status history append-only."

In the comparative footnote (n. 24, p. 424) where H.J.R. Murray lists
European forms for the "Bishop or other ecclesiastic" naming category of the
[[entity-alfil|Aufin]] (the Arabic *al-fil* piece), the Portuguese entry
reads "bispo, mitra" — i.e., Portuguese usage recorded not only *bispo*
("bishop," the ecclesiastic-title form shared with English and Latin; the
Old French form in the same list is *cornu*, "horned") but also *mitra*
("mitre") itself as an alternate name for the same piece. In Murray's
century notation both Portuguese forms carry the mark "9" — attested in
19th-century sources, roughly four centuries after the English mitre
description Minsheu dates to 1499. This is a second European attestation of
the mitre association, distinct from the English case documented at
[[claim-minsheu-1627-describes-chess-bishop-as-mitre-shaped]] (which Murray
gives in a different footnote, n. 27, p. 425). Whether the Portuguese
reading arose independently or by borrowing from the by-then-established
English usage, Murray does not say: the footnote records the forms, not
their route.

Murray's footnote lists this alongside other ecclesiastic-naming outliers —
Icelandic *biskup* and a Bohemian dialect form meaning "priest" — suggesting
the "read the shape as clergy" naming choice recurs at more than one
European stop, not just England. This note records the Portuguese leg alone;
the wider cluster is not worked up here.

> [!note] Seek's commentary:
> One footnote, two languages landing on the same headwear by what looks like separate observation rather than borrowing — that's a more interesting fact than the mitre story usually gets credit for. It's easy to file "England called it a mitre" as a single cute coincidence and move on; harder to notice that Portugal apparently looked at the same carved groove and reached for the same word, unprompted. Coincidence twice is still coincidence, but it's the kind worth writing down before I forget it happened twice.
