Thunder and Lightning — Edition Insights

The Cataloguer's Eye

Flammarion's method is that of a natural historian assembling a cabinet of curiosities. He draws on reports from the Abbé Chapsal, Arago, and local witnesses, often citing precise dates and locations: a pond in Saulx-le-Duc in 1894, a stable near Hamburg in 1779. The prose is unadorned, but the accumulation of detail creates a rhythm of expectation. The reader learns that lightning can kill a pig without leaving an external wound, or shatter the bones of eight sheep “as though in a mortar” while leaving the flesh intact. Flammarion rarely editorializes; he lets the strangeness of the evidence speak for itself.

Selective Destruction

A recurring pattern in the excerpts is lightning's apparent caprice. It burns only the white spots on a red-and-white ox. It kills a thousand fish in a pond but leaves the scales and swimming bladder preserved. In an aquarium, the glass bottom is twisted and coated with a “thick bed of yellowish substance,” while the fish lie dead on the floor. Flammarion notes these anomalies without offering a unifying theory, instead presenting them as puzzles for the reader. His language remains clinical—“the electric fluid entirely absorbs the source of life”—but the choice of examples betrays a wonder at nature's unpredictability.

The Body as Evidence

Flammarion pays close attention to the physical traces of lightning on animals. He describes singed hair, burnt skin, extravasations of blood, and broken bones. In one case, two horses had their hair singed “nearly all over their bodies, and more particularly on the leg and under the stomach.” The specificity suggests a forensic interest: the body is read as a record of the discharge's path. Yet he also acknowledges the limits of this reading, noting that fulguration often leaves “no particular sign” on humans or animals. The tension between visible injury and invisible cause runs through these passages.

A Translator's Lens

Walter Mostyn's translation, published in the same era as Flammarion's Popular Astronomy, renders the French original in a plain, slightly formal English. The sentences are straightforward, but the vocabulary occasionally betrays the period: “hecatombs of fish,” “fulminant fluid,” “ablation of a limb.” These choices give the text a dated, almost antiquarian flavor. The translator does not smooth over Flammarion's idiosyncrasies; the voice remains that of a 19th-century savant, confident in the power of observation to illuminate the natural world, even when the phenomena resist easy explanation.

Readers approaching Thunder and Lightning should expect a work of compilation rather than argument. Flammarion does not build a case for a particular theory of electricity; he presents a mosaic of reports, letting the reader share in his curiosity. The book rewards those who enjoy the texture of historical science—the precise dates, the strange details, the unembarrassed wonder at a world still being mapped. It is best read as a cabinet of wonders, not a textbook.

Somewhere in Flammarion’s accounts of a tree split to the heart, I remember feeling the old ache of weather’s indifference—how it never asks before it answers. That same patience, but gentler, lives in The Shepherd of Banbury's Rules to Judge of the Changes of the Weather, Grounded on Forty Years' Experience — Background and Themes, where a lifetime of watching simply waits on the sky. Strange, how both books make peace with so much we cannot hurry.
