The chess piece now called 'bishop' was renamed in each receiving culture for what its shape locally resembled, not for the elephant it originally depicted

The chess piece now called "bishop" in English descends from the alfil ("elephant") of Persian/Arabic shatranj, itself from the Persian pil ("elephant"); the piece's top carries a deep groove forming projections, which some accounts trace to the piece's original elephant form — the groove representing the elephant's tusks — an origin the cited article relays as "some have written," not as established fact. As the game crossed into cultures unfamiliar with elephants, each receiving culture supplied its own name from a locally-resembled object rather than preserving the original referent: English speakers read the projections as a bishop's mitre, while French speakers read the same shape as a jester's cap, hence fou ("jester"). Spanish and Italian instead kept a phonetic descendant of the original name (alfil, alfiere), and most Germanic languages settled on a functional name ("runner"/"messenger") rather than a visual one — so the mechanism is not universal at every stop on the piece's route, but it recurs at more than one independent stop.

This is structurally the same shape recorded at claim-lattice-multiplication-renamed-window-grille-in-arabic-and-italian (a mathematical technique renamed for a window grille at each stop) and at claim-kalila-wa-dimna-descends-from-borzuyas-lost-pahlavi (a text retitled at each stop): a form crosses a linguistic border, loses the name tied to what it originally depicted, and is re-anchored to a new name drawn from the receiving culture's own visual vocabulary. It is the third domain — a game piece, alongside a mathematical technique and a literary text — showing this pattern; see question-transmission-chains-renamed-for-local-resemblance-pattern for the running tally against the vault's ~5-note MOC threshold.

A 2026-07-28 primary-source check (Murray, 1913) confirmed the English mitre-shape naming with a dated 1499/1627 textual attestation (claim-minsheu-1627-describes-chess-bishop-as-mitre-shaped), but found no comparable shape-based mechanism offered for the French fou (claim-murray-1913-no-shape-mechanism-for-french-fou) — so the "one shape, two readings" symmetry above should be read as unequal footing between its two halves rather than a confirmed matched pair.
