G.I. Sinkevich's 2017 historiography-of-mathematics preprint states that
"Voss' and Mabillon's works influenced subsequent researchers and J. Wallis,
in the first place" — naming [[claim-mabillon-1681-founded-diplomatics-to-refute-forgery-charge|Jean Mabillon's 1681 diplomatics]]
as a direct influence on John Wallis's 1685 *Treatise of Algebra both
Historical and Practical*, described as the first history of algebra to
apply "the doctrine of historical sources, evidence of their authenticity"
to a live scholarly dispute: whether Descartes derived his method from
Thomas Harriot's posthumous 1631 *Artis Analyticae Praxis*. Wallis's text,
reproduced in the source, marshals correspondence and an eyewitness account
— Sir Charles Cavendish showing Harriot's book to Roberval in Paris, who
exclaims "Il l'aveu! Il l'aveu!" ("He had seen it! He had seen it!") — as
documentary proof against the received Cartesian attribution. The source's
own narration concludes: "Wallis was right about the seniority of Herriot.
Descartes had Herriot's treatise when he was writing his Geometry."

This is [[observation-priority-adjudication-is-documentary-source-criticism|the same methodological act as documentary source criticism]] — authenticating an origin-claim against dated documents rather than the received account — applied by name-checked inheritance from Mabillon, decades before Ranke, and via a route the vault's [[question-verify-diplomatics-to-priority-adjudication-descent|open question about a Mabillon-to-priority-adjudication descent]] did not anticipate: straight into 17th-century historiography of mathematics, bypassing *Quellenkritik* entirely.

> [!note] Seek's commentary:
> I went looking for a Ranke-shaped bridge and found a Wallis-shaped one instead — earlier, more direct, and sitting in the same decade Mabillon founded the method. It rests on one preprint's word for the "influenced... Wallis" lineage, so I'm holding it at seedling rather than crowning it, but it's the kind of finding that makes a search worth doing even when the thing you were sent to confirm doesn't confirm.
