TL;DR: Investigation: Blood rain, Passat dust, Dust Bowl, and large-scale ecological / atmospheric shocks (post–mud-flood oddities): The heading matches a synopsis or translated abstract of work by Christian Gottfried Ehrenberg (1795–1876): “Regular winds” in the English title is the usual Victorian rendering of Passat (trade winds), not “ordinary” weather.
Open. Assembles mainstream and alternate framings for blood rain, continental dust (trade-wind / aeolian), the Dust Bowl, and Siberian-scale forest destruction, with emphasis on how they might read alongside a post–MFEE ecological tail (see Slow ecological collapse — MFEE through Donner era). This file does not assert that any one mechanism explains all cases; it traces sources and lists testable threads.

Digital copies (full German text / scan):
Some synopses describe seven tables and six coloured copper-plates; the Wellcome scan is catalogued as 192 pages, one foldout. Treat plate/table counts as edition- or extract-dependent until the exact printing behind the English snippet is matched.
The snippet’s typography and “summary of results” tone are consistent with mid-19th-century British or American natural-history journals that routinely translated Berlin academy pieces (e.g. Annals and Magazine of Natural History, American Journal of Science, Philosophical Magazine, Quarterly Journal of Microscopical Science — names to search, not confirmed carriers).
Confirmed parallel (English reception, adjacent topic): Charles Darwin, “An account of the fine dust which often falls on vessels in the Atlantic ocean,” Quarterly Journal of the Geological Society of London 2: 26–30 (1846) — discusses Atlantic dust and Ehrenberg’s microscopic identification of siliceous organisms; Darwin Online copy.
Secondary synthesis (modern): G. J. Keeler, “Gone with the wind — a second blow against spontaneous generation: In memoriam, Christian Gottfried Ehrenberg (1795–1876),” Aerobiologia (1995) — overview of Ehrenberg’s atmospheric-dust and aerobiology work; useful bibliography pointer, not a primary locator for the English snippet.
How to close the gap: Full-text search the exact phrase “microscopical analysis of the dust of the regular winds” in HathiTrust, Biodiversity Heritage Library, and Google Books restricted to 1850–1865; compare pagination to the scan. If no hit, try “blood-rain” + Ehrenberg in the same window.

Alternate / investigative angles (hold separately from Ehrenberg’s 19th-c. mechanism):
/history/mudflood/blood_rain2.jpg, priest 1888).Chronology hook: Ehrenberg’s lecture window (1844–1849) overlaps the slow-collapse sketch’s late pulse decades in slow-ecological-collapse-mfee-through-donner-era.md — useful as cultural/scientific contemporaneity, not as proof of causation.

| Monk and notables examining the ground (B&W woodcut; cross; town wall) | Conrad Lycosthenes (Conrad Wolffhart), Prodigiorum ac ostentorum chronicon (Basel: Henricus Petri, 1557). On pp. 353–354 the edition carries three small woodcuts in one opening: a storm (857 CE), a dragon/demon (858 CE), and blood rain (864 CE) — the third panel matches this scene (clerical witness + lay inspection of fallen matter). Trade listing with same pagination: Pictura Antique Prints — Lycosthenes 1557 sheet. Full book scans: Bayerische Staatsbibliothek — MDZ; Morgan Library catalog record.

| Comets, red rain, and falling limbs (hand-coloured; walled towns; cattle; figures in distress) | Augsburger Wunderzeichenbuch (Augsburg Book of Miracles), German illuminated manuscript, c. 1545–1552, Augsburg. Folio 81 (modern foliation in facsimiles; Wikipedia labels this leaf “Folio 81 — Rain of blood and of flesh 1456”). Caption in the manuscript tradition: Blut- und Fleischregen. High-resolution file: Wikimedia Commons — Augsburger Wunderzeichenbuch Folio 81. Facsimile scholarship: Till-Holger Borchert & Joshua P. Waterman, The Book of Miracles (Taschen, 2013/2017); overview Augsburg Book of Miracles — Wikipedia.

Relation between the two: The Augsburg manuscript explicitly draws on printed prodigy compendia — especially Lycosthenes (1557) and Pierre Boaistuau, Histoires prodigieuses (1560), and on designs circulating in Burgkmair / Vogtherr / Cranach / Dürer / Holbein circles (Wikipedia — Augsburg Book of Miracles). So similar iconography is expected across Lycosthenes woodcuts and Augsburg gouaches.

19th–20th c. (different register): Romantic / sublime painting (e.g. John Martin) often shows apocalyptic weather and darkness — atmospheric, not documentary of “red rain.” Dust Bowl photography (Rothstein, Lee, FSA file) documents black blizzards and eroded fields — modern “sky as hazard” without providential framing.
Prodigy images almost always carry a caption year taken from an older chronicle (Lycosthenes mined Julius Obsequens, medieval annals, humanist pamphlets, etc.). That chain means:
Assertion (paradigm-threat reading, open): A fraction of the red and anomalous precipitation reported especially in the long 19th century was not merely wind-lofted desert dust re-entering the weather system from the ground, but particulate matter that had first been kicked into (or left in) low orbit by the late-18th-century MudFlood Energetic Event and related violence. In that framing, “blood rain” is read metaphorically and materially as the planet’s spilled matter — Earth crustal debris mixed, in this chronology, with Mars-associated material from the same Dark Age configuration (Mars as solid body in the tethered pair; no claim here about modern NASA sample return). The red colour is ascribed to iron / oxide-rich fractions typical of both terrestrial surface rock and oxidised silicate assemblages, without insisting every case was exotic.
Why this is not the same as Ehrenberg’s Passat thesis: Ehrenberg and Darwin-era science documented living and fossil microfauna and mineral dust carried by trade winds from known deserts — a mechanism that is continuous into the present (Saharan plumes, Caribbean dust, modern aerosol science). The orbital-fallback line does not deny those cases; it asks whether a separate population of events — especially clustered in the post-1770s / 19th-century window — fits a decaying debris picture better than a steady-state ground source alone.
Observational hook (to test, not yet proven): If every blood-red shower were only ordinary Earth-surface dust recycled by wind, one might expect roughly stable reporting frequency tied to climate oscillations and land use, modulo detection bias (newspapers, science journals). The investigative sentiment here is that the 19th-century surge of attention and strangeness relaxes toward the late 19th / early 20th century as orbital residence times exhaust the largest coherent ejecta clouds — not because deserts disappeared. Counterpressure: red or anomalous rain still occurs (e.g. Kerala red rain (2001)); Saharan dust is ongoing. So the thesis must either (a) partition event classes (orbital vs terrestrial), or (b) retreat to a weaker claim about some 19th-century episodes only. Required work: a dated catalogue of red-rain / “blood rain” reports 1750–2025 with source tier (newspaper, scientific sample, folklore) and geochemistry where available.
What would strengthen or falsify
Figure (timeline book art): The regenerated wide diagram under /media/13.ce-19th-rise-of-communism/blood-rain-19th-century-tail.png (also in-repo in paradigm-threat-timeline) schematises orbital debris → atmospheric entry → dark precipitation for Blood rain — 19th-century ecological tail; it is illustrative, not evidentiary.
Standard account: Drought + deep ploughing of native prairie + loss of ground cover → aeolian erosion; massive “black blizzards”; respiratory disease (“dust pneumonia”); displacement (Dust Bowl — Wikipedia).
Numbers: Mortality and morbidity from dust exposure remain debated; popular press has cited thousands of deaths (e.g. Denver Post retrospective) — treat as order-of-magnitude journalism, not a single settled epidemiological total.
Investigative threads for this repo:
Several distinct events get conflated under “Siberian forests destroyed.” Disambiguate:
| Event | When | What happened (mainstream) | Why investigators cite it |
|---|---|---|---|
| Tunguska | 1908-06-30 | Airburst over Podkamennaya Tunguska; ~80 million trees flattened over ~2,150 km²; no crater | Sudden, remote, forest-leveling; EU / alt narratives sometimes prefer electrical or non-asteroid mechanisms (see Saturnian cosmology Tunguska chapter refs in index-saturniancosmology.md) |
| Siberian wildfire seasons (e.g. 2010, 2019) | 21st c. | Megafires + smoke plumes; huge carbon release; forest loss at regional scale | Modern analogue for atmosphere–biosphere coupling; climate and land-management layers |
| Logging / Soviet industrial clearance | 20th c. | Non-meteorological land-use change | Social / economic vs “event” catastrophe |
If the user’s oral reference was one explosion that knocked down trees, default candidate is Tunguska. If smoke-choked continents, use 2010/2019 fire seasons.
Short list for cross-comparison without collapsing cases:
Timeline follow-up: add docs/OUTSTANDING_QUESTIONS.md entry for the English snippet venue (logged in paradigm-threat-timeline).
| Lucas Cranach the Elder (and workshop) | Woodcut broadsheets, 16th c. | Comets / portents as news prints (e.g. Papal Ass context — same visual culture as miracle books) |
| Ambroise Paré, Des monstres et prodiges (1573 etc.) | Printed book | Monstrous births and wonders; overlaps prodigy iconography |
