The Deposed Serpent of Gloucester (1817)
Eight witnesses swore before a Justice of the Peace to a large marine animal in Gloucester Harbor, each interrogated separately on the same 25 questions. Two centuries later, we ran the record's wording-independence measure over their depositions. The 1817 protocol passes.
8
people deposed under oath in August 1817, interrogated separately by Justice of the Peace Lonson Nash, who wrote: "no one knowing what the others had testified."
What they kept saying:
In their own words

What the evidence shows
Points toward something real
- Measured wording independence: TYPICAL 0.703, in the mostly-independent band; no pair of depositions approaches duplication (worst phrase-overlap 0.29, where real copying runs 0.8 and above)
- The closest pair's shared phrases trace to the committee's own 25 questions echoed in the answers, and to the notary formula, not to shared narrative
- Disagreements were preserved rather than smoothed: Nash himself recorded that Allen differed from the others on the animal's motion and visible portions
- Convergent on substance, idiosyncratic in wording: the same two-sided signature honest independent testimony shows in modern data
Points the other way
Nothing yet that argues against the pattern. If you have something, send it.
Ordinary explanations people have offered
- A 2019 re-analysis proposes the sightings are consistent with known marine animals seen under unusual conditions; the committee's own later examination of a supposed juvenile specimen found it to be a deformed common snake
Still unanswered
- What the eight deponents actually saw in the harbor remains unidentified in the record itself
- The measurement says the witnesses were independent; it says nothing about what they witnessed
The numbers behind this case
Wording independence near 1.0 means people described it in their own words. A low number means some accounts may be echoing each other, and we show it either way.
