8,629 ATTESTATIONS · 834 WORKS · 12TH–20TH CENTURIES

One in four equalities needs a tolerance

When a 13th-century author writes “this equals that”, does it? We machine-recomputed 8,629 gematria claims from 834 works. Three in four hold exactly.

75.3%

6,494 of 8,629 attestations hold with no adjustment. The remaining 2,135 — 24.7% — need im hakolel: plus or minus one. This is not an error of the tradition; it is its tolerance, and nobody had measured it before.

Especially 110: of 106 attestations, 90 rest on the adjustment alone. The equality the tradition repeats most often is almost always one with a tolerance.

For each of the 1,023 values, the earliest attestation found. Two peaks: the 14th century and the 16th. Dates of works are approximate, so this is a picture, not a chronometer.

Counting rule

Mispar hechrachi: alef 1 … tav 400, final letters equal to the ordinary ones, vowel points removed. “Exact” — both sides equal. “With adjustment” — a difference of exactly 1. Every row recomputed by machine; the CSV is open.
