Napoleon Plague Screenshot — Book Identification, Citation Forensics, and Claim Decomposition
TL;DR: The circulated page is almost certainly from Daniel Roytas, Can You Catch a Cold? (2024). The famous public image of the episode is Antoine-Jean Gros, Bonaparte visitant les pestiférés de Jaffa (1804, Louvre) — state propaganda between empire and coronation, advised by Egypt veteran Vivant Denon, not a neutral record. Witnesses split: Berthier silent; Bourrienne “fast pace”; Desgenettes “grabbed the sick”; Peterson cites one corpse carried in a ward (11 Mar 1799). Roytas compresses Pyramids + Murad Bay + zero deaths; Gros compresses sack/opium scandal into touch-the-bubo heroism. Cross-read: virus isolation audit, Franklin screenshot hunt.
Status: Open — book on disk (~/dev/wget/roytas-2024-can-you-catch-a-cold/); footnote 8 = Winterbottom 1828; Winterbottom primary and Murad Bay literal still to verify.

1. Why someone would write this — without assuming fraud
People rarely fabricate whole book pages when a published 2024 title already carries the same paragraph in reviews and Substack summaries. The more ordinary explanations:
| Mechanism | Plausibility |
| Real book, compressed secondary history | High — anticontagionist shelf literature routinely merges Desgenettes, Napoleon’s morale visits, Clot-Bey’s experiments, and post-Pyramids Giza HQ into one rhetorical block. |
| Typo / ear mistake: Murad Bey → “Murad Bay” | High — after the Battle of the Pyramids (21 July 1798), Napoleon’s HQ is attested at Murad Bey’s palace, Giza (napoleon-empire.org — Pyramids). “Bay” is not a standard toponym in the campaign. |
| Conflated “sixty” | High — Napoleon’s 1799 intelligence on Acre reported >60 deaths/day from plague inside the besieged city (Peterson / Howard 1961), not “sixty enemy soldiers at Murad Bey’s house.” |
| Conflated corpse-handling date | High — Desgenettes’ attested corpse lift is 11 March 1799 at Jaffa, not “around the Pyramids” in July 1798 (Desgenettes 1802). |
| Motivated oversell (germ-theory skeptic pipeline) | Medium — Roytas/Bailey lane sells failed contagion narratives; survival after exposure becomes proof unless readers track ~1,700 expedition plague deaths (InsideGMT). |
| Pure hoax page | Low — matches known book; red pen underlines look like study markup, not random meme text. |
Author stake (why Paradigm Threat cares): The screenshot is a trace in the same contagion-memory war as Flexner, COVID isolation headlines, and ætheric-disease framing — not because every sentence is true, but because finding the book lets us grade which claims are Roytas, which are Roytas’s sources, and which are compression error.
2. Book identification — Roytas (2024)
2.1 Matched publication
| Field | Value |
| Title | Can You Catch a Cold?: Untold History & Human Experiments |
| Author | Daniel Roytas (editor credited); Dr Samantha Bailey (co-author on retail listings) |
| Year | 2024 (Goodreads: 23 Mar 2024; Amazon ISBN 9781763504400 / 1763504417) |
| Scope | Germ-theory skepticism; 1798–mid-20th c. transmission experiments; 1,000+ citations (publisher blurb) |
| Retail | Google Books, Amazon, Goodreads |
2.2 Independent echo of the exact screenshot paragraph
Unbekoming — The Physician Who Smeared Himself with Smallpox (Dec 2025) quotes Roytas verbatim on Napoleon:
Napoleon himself reinforced the demonstration. He grabbed the corpses of soldiers who had died from plague with his bare hands and lifted them about. He remained unaffected. Following the Battle of the Pyramids, Bonaparte, Desgenettes, and their staff occupied quarters at Murad Bay where sixty enemy soldiers had died of the plague just days prior. Despite living within those pestilent walls for some time, not a single Frenchman contracted the disease.
That match means the screenshot is very likely a photograph of Roytas’s book (or a downstream quote of it), not an anonymous paste.
2.3 Footnotes on the Napoleon block (Chapter 11) — resolved from local EPUB/PDF
Local mirror: ~/dev/wget/roytas-2024-can-you-catch-a-cold/ (roytas-2024-can-you-catch-a-cold.epub, .pdf, INDEX.md).
Passage: Ch. 11 Contagion Trailblazers, The Pioneers of Human Transmission (1798 – 1900), pp. 204–206.
| Note | Roytas citation | Clause anchored |
| 5 | Harris JC. 2006. Arch Gen Psychiatry. 63(5):482 | Plague after fortress liberation |
| 6 | Kelly C. 2010. Can Bull Med Hist. 27(2):321–42 | Desgenettes self-inoculation / remained well |
| 7 | Coudray F. 1926. Arch Med et Pharm Milit. 85(4):387–403 | Desgenettes thread (military-medical) |
| 8 | Winterbottom T. 1828. Edinb Med Surg J. 30(97):321–44 | Murad Bay; sixty enemy dead; no Frenchman infected |
| 9 | Bulmus B. 2012. Plague, Quarantines and Geopolitics…, pp. 130–51 | Clot-Bey 1835 injections |
Footnote 8 verdict: Roytas’s immediate source for the screenshot’s zero-infection / Murad Bay clause is Winterbottom (1828), not Gros (1804), not Desgenettes (1802). TODO: Read Winterbottom pages 321–44 for literal “Murad Bay,” “sixty,” and army-wide zero cases vs Roytas compression.
Book quirks: spells Renée Desgenettes; uses Murad Bay (mainstream maps: Murad Bey’s palace, Giza).
Not Arthur Firstenberg: The Invisible Rainbow is EMF-focused; no hit for this Napoleon block in quick passes.
3. Screenshot claims — decomposition table
| # | Claim in graphic / book | Preliminary verdict | Best mainstream anchor |
| 1 | Napoleon knew plague was not contagious | Partial — acted with anticontagionist medical staff; also feared plague, used isolation, cited “germs” at Acre | Ackerknecht — Egypt 1798–99; Peterson |
| 2 | Grabbed corpses with bare hands, lifted them about | Distorted — Desgenettes: one corpse carried, 11 Mar 1799; Gros 1804 shows touch bubo + earlier sketch of carrying soldier (§5) | Desgenettes 1802; Louvre — Gros 1804 |
| 2b | Public “memory” = Gros painting | Propaganda — not Berthier’s report; Salon 1804 | §5 |
| 3 | Bonaparte remained unaffected | Supported for Napoleon personally | Same |
| 4 | Around Battle of the Pyramids | Misdated for corpse stunt — Pyramids Jul 1798; hospital visit Mar 1799 | Battle of the Pyramids |
| 5 | Murad Bay quarters; 60 enemy plague dead | Unverified / likely error — Murad Bey’s palace, Giza; “60/day” fits Acre reports, not attested for palace | napoleon-empire.org; Peterson |
| 6 | No Frenchman in quarters caught plague | Contradicted at expedition scale — ~1,700 plague deaths; 54 medical officers | InsideGMT |
| 7 | Alleviated soldiers’ fears | Partial — Jaffa visit had intended morale effect | Peterson |
4. Belief vs evidence — Napoleon and the medical corps
4.1 Documented medical anticontagionism (expedition)
When plague struck the Egyptian/Syrian campaign (1798–99), French medical commanders Assalini and Desgenettes, and British Sir Robert Wilson, held plague to be non-contagious in the period’s sense (Ackerknecht 2009, abridging 1948 lecture).
Desgenettes inoculated himself with bubo material (1798) — attested in anticontagionist literature and V&A lithograph series (“calmer leur imagination”) — V&A — Desgenettes lithograph.
4.2 Napoleon — behavior and attributed psychology
- Fear + politics: Recognized plague could destroy the army; visited lazaretto to reduce terror (Peterson).
- Attributed quote (Malus 1892, secondary): Fear/imagination kills; moral courage and march are prevention — not a laboratory theorem.
- Not a clean doctrine: Suggested opium for plague-stricken troops; plague ravaged French ranks regardless of stunts.
Conclusion for §4: Evidence supports that Napoleon operated inside a staff that denied person-to-person contagion as then understood; it does not support the banner’s modern “plague is not contagious” without qualification (WHO plague fact sheet).
5. Antoine-Jean Gros, Bonaparte Visiting the Plague Victims of Jaffa (1804)
This section is the visual and propaganda layer most people “remember” when they hear about Napoleon and plague. It is not interchangeable with Roytas’s 2024 prose or with a single eyewitness paragraph — but it shapes what later books, memes, and contagion debates think happened.
5.1 Work — facts on the canvas
| Field | Detail |
| French title | Bonaparte visitant les pestiférés de Jaffa (11 mars 1799) |
| Artist | Antoine-Jean Gros (1771–1835), pupil of Jacques-Louis David |
| Date painted | 1804 (Salon 18 Sept 1804, no. 224) |
| Commission | Napoleon as First Consul → Emperor propaganda pipeline; ordered via Ministry of the Interior (Louvre collections record) |
| Studio | Jeu de Paume, Versailles |
| Advisor | Dominique Vivant Denon — artist of the Egyptian expedition, later Louvre director; present at Jaffa in March 1799 per Musée Condé account |
| Medium / scale | Oil on canvas, 532 × 720 cm (~17 × 23 ft) — monument scale for Paris Salon |
| Current location | Musée du Louvre (ark:/53355/cl010062570) |
| Salon subtitle (1808) | Bonaparte, général en chef de l’armée d’Orient, au moment où il touche une tumeur pestilentielle en visitant l’hôpital de Jaffa |
Alternate English titles: Bonaparte Visiting the Plague Victims of Jaffa; Napoleon Visiting the Pest House in Jaffa (Smarthistory).
5.2 What the painting shows (composition)
Setting (often mis-described): Not a mosque — the courtyard of the Armenian Saint Nicholas Monastery, Jaffa, used as a military plague hospital (Wikipedia — composition; Louvre description: “Cour de mosquée servant d’hôpital militaire” — Ottoman-era wording).
Central gesture: Napoleon, lit like a hero, touches the armpit bubo offered by a sick soldier. An officer behind him reaches as if to stop the contact. Another officer covers mouth and nose (period “miasma” fear, not yet flea theory).
Foreground / margins:
- Prostrate and dying soldiers; stretcher with likely corpse (left background — two men carry a covered form).
- Arab doctor treating a patient; blind man moving toward Bonaparte.
- Orientalizing staff: bread distribution, horseshoe arch, oversized French flag on breached Jaffa walls, smoke.
Iconographic program (Scholarly consensus):
- Christ healing the sick (Christian miracle grammar applied to a general) — Smarthistory.
- Apollo Belvedere pose — divine + military hero fused.
- Royal touch for scrofula — Bourbon sacred kingship recycled for Bonaparte’s empire moment (Wikipedia — royal touch).
Style: Proto-Romantic — warm color, suffering bodies in foreground; breaks David’s cool neoclassicism. Darcy Grimaldo Grigsby situates the canvas in “extremities” of empire — plague as colonial crisis painted in Paris, not observed neutrally (Extremities, Yale UP 2002, cited on plague/Jaffa in Wikipedia via p. 65).
5.3 Event date and campaign context
| Date | Event |
| 7 Mar 1799 | French capture and sack of Jaffa — massacre of prisoners, atrocity reports |
| From Jan 1799 | Bubonic plague in army (identified before March) |
| 11 Mar 1799 | Hospital visit — date on Louvre title and most military histories (Peterson quotes Desgenettes 1802 for ~1.5 hours in hospital + corpse carried) |
| 21 Mar 1799 | Date used in some art-history teaching (Smarthistory) — treat as secondary to 11 March military sources |
| 23 Apr 1799 | Bonaparte suggests fatal opium to Desgenettes for plague patients (refused) — Acre siege |
| 27 May 1799 | Second visit to plague victims (Wikipedia) |
| 1804 | Painting finished for Salon — five years later, under empire politics |
Plague in Jaffa was real regardless of contagion theory: within days of occupation, hospitals filled; ~30 deaths/day in garrison at peak per Malus (via Peterson); expedition totals still ~1,700 plague dead overall.
5.4 Why Napoleon commissioned it — propaganda tasks
The painting is state media, not journalism. Documented aims include:
Counter opium-euthanasia rumors — Reports that Bonaparte ordered ~50 remaining plague patients poisoned on retreat from Syria (Wikipedia; controversial in historiography — some survivors alleged, Desgenettes refused mass euthanasia per Peterson).
Counter Jaffa atrocity press — Sack, ~3,000 prisoners killed, “mission civilisatrice” contradicted (Wikipedia — historicity; Grigsby 2002 footnote chain).
Morale / contagion panic — Same function as live visit: show commander unafraid of plague touch so troops return to duty.
Empire timing — Exhibited between proclamation as emperor (18 May 1804) and Notre-Dame coronation (2 Dec 1804) — image of compassionate thaumaturge-general for domestic audience.
Smarthistory states plainly: Napoleon “masterfully manipulated his image,” and the work is “pure propaganda.”
5.5 Historicity — witnesses vs canvas
| Source | What it says about the visit | Tier |
| General Berthier — campaign report | No mention of hospital-theater visit | A (negative witness) |
| Bourrienne — private secretary | Crossed lazaretto at a fast pace only | A |
| Desgenettes 1802 — cited by Peterson | ~1.5 h in hospital; helped carry hideous corpse with burst bubo; Bonaparte calm | A (physician witness) |
| Desgenettes — Wikipedia summary of memoirs | “Grabbed the sick” and helped transport them | B |
| Gros painting | Touches live bubo; heroic light; officer restrains | C (1804 artwork) |
| Musée Condé — preparatory history | Gros’s first idea: Bonaparte carrying plague-stricken soldier in his arms in bare hospital room — closer to Roytas “lifted” rhetoric (Condé notice PE-428) | B (composition evolution) |
| Denon | At Jaffa March 1799; fed Gros memories for Orientalist detail | B |
Forensic takeaway:
- Something happened on 11 March 1799 — multiple lines agree Bonaparte entered the pest house.
- Bare-hand touch of bubo is the Salon fiction optimized for miracle and empire; corpse-lifting is Desgenettes-specific and appears in Gros’s earlier compositional idea, not the final giant canvas centerpiece.
- Roytas (“grabbed corpses … lifted them about”) aligns with merged memory: Desgenettes corpse carry + Gros carrying-soldier sketch + anticontagion stunt lore — not with a single clean primary that says Napoleon toured corpses at the Pyramids.
5.6 Medicine in the picture vs period belief vs modern biology
Inside the frame:
- Doctor incising bubos (heroic but ineffective — weakens patient).
- Touch-as-courage against miasma / contagion panic.
Period medical split (same army):
- French officers often anticontagionist (§4).
- Soldiers still knew buboes meant plague; doctors initially told them otherwise to limit panic (Peterson).
Modern note (Wikipedia, post-Simond 1898): Bubonic plague is not reliably spread by touch alone; fleas matter; pneumonic cases can aerosolize. The painting’s “touch proves non-contagion” meme imports 1804 theater into 21st-c. germ debates — both sides can cherry-pick.
Paradigm Threat read (cross-link, not proof): The canvas is predictive programming for germ triumph’s mirror image — it freezes one frame of fearless contact so later textbooks can say “see, they thought courage beat plague,” or skeptics say “see, contagion disproved.” Both reads skip expedition mortality and retreat conditions (§6–8 in virus media PP — state + spectacle disease grammar).
5.7 From painting to Roytas screenshot — memory pipeline
Why this matters for the repo: When validating contagion history, the painting is an artifact of war propaganda, not a lab result. Treating Gros as camera footage is the same class of error as treating Roytas as Desgenettes without footnote 8.
5.8 Scholarly and museum sources (reading list)
| Resource | Use |
| Louvre — collections record | Provenance, Salon payment 16,000 francs, physical description |
| Smarthistory / Khan Academy | Teaching text; propaganda + iconography |
| Wikipedia — full composition analysis | Witness table, medical detail, royal touch |
| Grigsby, Extremities (2002) | Empire, plague, failure motifs in post-revolutionary history painting |
| O’Brien, After the Revolution: Gros, Painting and Propaganda Under Napoleon (2008) | Cited by Louvre — TODO: read pp. 90–91 |
| Musée Condé — preparatory sketch PE-428 | Carrying soldier first composition; Denon at Jaffa |
| New Orleans Museum of Art — preparatory sketch | Alternate comp study |
| V&A — Desgenettes lithograph | Parallel propaganda: inoculates plague before soldiers (“calmer leur imagination”) |
6. Murad “Bay” hypothesis — Bey’s palace + merged anecdotes
Working forensic thesis: Roytas (or his footnote 8 source) collapsed three coordinates into one paragraph for rhetorical force. That is sloppy history, not necessarily fiction.
7. Book hunt and verification plan
| Step | Action | Status |
| 1 | Acquire Roytas 2024 PDF/paper (library, purchase, Anna’s Archive slug 1763504417) | TODO |
| 2 | Locate screenshot page; photograph footer 8 and full References for Napoleon subsection | TODO |
| 3 | Pull primary named by note 8 (expect Desgenettes Histoire médicale de l’armée d’Orient, Herold 1962, Maclean, or Clot-Bey) | TODO |
| 4 | Compare Roytas wording to Gutenberg Desgenettes (French) for self-inoculation / oil-on-bubo passages | TODO |
| 5 | Log whether later editions fix Murad Bay → Murad Bey | TODO |
Archive searches (2026-05-22): "Murad Bay" + Napoleon → no hits in Internet Archive snippet API; phrase appears Roytas-dependent.
8. Related investigations (cross-reference)
| Investigation | Rhyme |
| Virus media — predictive programming | State spectacle disease grammar; Gros as frozen frame (§5.6) |
| Virus isolation — skeptical audit | Lane B denial vs Lane C ætheric; failed challenge literature as CO-shaped fork |
| Viruses — reader essay | Institutional capture of disease ontology |
| Franklin Palatine screenshot hunt | Real book page vs witness mismatch workflow |
| Exorcism / disease / colonial memory | Demon–disease overlap without single origin at crusades |
| Napoleonic artillery / airship (open) | Same Napoleonic technology-memory lane (weak direct tie) |
| Napoleon — Egypt, Siberia, Curie (dossier) | Elite science hubris, corrected French dates, Fomenko Egypt, mutant PP |
| Lay article — Napoleon carried corpses | Reader essay — Gros, empires, Curie rhyme, captured medicine |
Thematic (not proof): Roytas paragraph supports terrain/anticontagion readers who already doubt COVID isolation headlines; Paradigm Threat should cite the book when discussing the screenshot, and decompose errors so the strong parts (Desgenettes experiment, morale theater) are not lost in debunk of the weak parts (Murad Bay, zero mortality).
9. Questions to clarify, verify, or debunk
| ID | Question | How to adjudicate |
| Q0 | Did Roytas footnote 8 cite Gros, Desgenettes, or a modern anticontagionist retelling? | Closed: Winterbottom 1828 — not Gros/Desgenettes |
| Q1 | What does Roytas footnote 8 cite verbatim? | Closed: Winterbottom T. 1828. Edinb Med Surg J 30(97):321–44 — see ~/dev/wget/roytas-2024-can-you-catch-a-cold/INDEX.md |
| Q2 | Does any pre-Roytas text use “Murad Bay” (not Bey)? | Google Books N-gram / HathiTrust "Murad Bay" plague |
| Q3 | Is sixty enemy soldiers in Murad Bey’s palace in Desgenettes, Herold, or La Jonquière? | Primary read |
| Q4 | Did Roytas conflate Clot-Bey 1835 prisoner injections with 1798 campaign? | Roytas ch. + Clot primary |
| Q5 | Page layout: which chapter is the screenshot? | Match pagination to TOC |

Limits and disclaimers
Prisca sapientia (epistemic foundation): This investigation assumes prisca sapientia—the historical and philosophical belief that the ancients possessed a vast, profound understanding of the universe, nature, and theology that was subsequently lost or degraded. Modern consensus science and institutions are not treated as default truth; evidence tiers below adjudicate specific claims.
This file identifies the source book and grades screenshot claims against mainstream military-medical history. Footnote 8 is transcribed from the local EPUB (Winterbottom 1828); the primary still needs reading. It does not assert that bubonic plague is non-infectious, that Roytas is correct on all counts, or that Napoleon’s stunts prove germ theory false. Author thesis material elsewhere in the repo (ætheric disease, anticontagion sympathy) is cross-linked, not imported as automatic proof here.
