Jean-Baptiste Pérès
French physicist

Jean-Baptiste Pérès (1752–1840) was a French physicist best known for his 1827 pamphlet Grand Erratum, a polemical satire, translated into many European languages, that attempted "in the interest of conservative theology, to reduce to an absurdity the purely negative tendencies of the rationalistic criticism of the Scriptures then in vogue" (as Frederick W. Loetscher described what he called "the celebrated pamphlet" in The Princeton Theological Review 1906) through humorously suggesting ways in which the history of Napoleon Bonaparte could be shown to be an expression of an ancient sun myth.
Pérès was professor of mathematics and physics at the University of Lyon, later a government attorney and finally librarian at Agen.
Grand Erratum
The pamphlet's complete title in French was Comme quoi Napoléon n’a jamais existé ou Grand Erratum, source d'un nombre infini d'errata à noter dans l'histoire du XIXe siècle ("It seems Napoleon never existed or Grand Erratum, source of an infinite number of errata as noted in the history of the 19th century").
The pamphlet's satire was directed at Charles François Dupuis (1742–1809) and his influential work Origine de tous les Cultes, ou la Réligion Universelle (1795), which attempted to prove that all religions were equally valid and based on common and universal imagery and magic numbers.
Pérès presents an overly rationalistic interpretation of the analogies and etymologies of elements in the popular understanding of Napoleon's life in order to show how, just as the Scriptures or other religious texts could be argued to be mythical, so could Napoleon's life.
Summary of the pamphlet
(The following summary is based on Sonnenfeld; see below. Direct quotations also come from Sonnenfeld.)
The name of Napoleon is suggested to be similar to that of the Ancient Greek sun god Apollo - the name supposedly from the verb apollyô or apoleô, "to exterminate" (the initial N in "Napoleon" could be derived from the Greek prefix nè or nai, "veritable"). Pérès derives the name from the event during the Trojan War when the Sun shone with unusual force, killing many of the Greek soldiers, as revenge for Agamemnon capturing Chryseis, the daughter of the priest of Apollo, Chryses. The family name Bona parte ("good part") could be seen as coming from a dualistic view of the good or light as one extreme, with mala parte ("bad part") being the opposite, darkness or hell (Pérès refers to the proclamation abi in malam partem, made by the priest during the ritual of exorcism).
Several other aspects of Napoleon's origin and family could also be cast as betraying supposedly mythological origins:
The location of Napoleon's birthplace, Corsica, in relation to France, corresponds to that of Delos, which is the mythical place of Apollo's birth, in relation to Greece.

Why this record matters
The phrase “french physicist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 27, 2026. The linked authority identifier is Q2344605. VIAF identifies the subject as 14925393. The Library of Congress control number is n91032771. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1752, 1840, 1827 and 1906.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
