The rain of blood, also known as blood rain, was an unusual event that was thought to be a bad omen in Antiquity, and this belief persisted into the Middle Ages and well into the Early Modern period.
Blood rain has occurred throughout history, from ancient times to the present. The first literary instance is in Homer’s Iliad, where Zeus causes a rain of blood twice, once to warn of slaughter in a battle. The same portent appears in the work of the poet Hesiod, who wrote around 700 BC; author John Tatlock speculates that Hesiod’s story was influenced by the Iliad.
Plutarch, a first-century Greek biographer, also recounts a tradition of blood rain during Romulus’, Rome’s, reign. Livy and Pliny, Roman authors, record some later cases of blood rain, with Livy describing it as a bad omen.
Enslaved workers in Wilson County, Tennessee, reported in July 1841 that just before noon, a small red cloud appeared in an otherwise clear sky; from the cloud fell a shower of “blood, muscular fiber, adipose matter,” in the words of a local physician, W. P. Sayle, who investigated it on the spot.
Sayle wrote to a chemistry professor at the University of Nashville, enclosing some samples:
“The particles I send you I gathered with my own hands; the extent of the surface over which it spread and the regular manner in which it exhibited on some green tobacco leaves leave very little or no doubt of its having fallen like a shower of rain….I have sent what I think to be a drop of blood, the other particles composed of muscle and fat, although the proportion of the shower appeared to be a much larger quantity of blood than of other properties.”

G.W. Bassett of Virginia, another doctor, described the incident in a letter to a colleague in the spring of 1850:
“Around four o’clock yesterday, Good Friday, a small cloud passed over Mr. Chas. H. Clarke and several of my servants, a few paces from the south bank of the Pamunkey River in the lower end of Hanover County, Virginia, on the estate called Farmington, and discharged various pieces of flesh and liver, too well defined in each sort to allow any mistake in their character.
I gathered from the spot this morning from four to six ounces, distributed over the above-mentioned surface; the pieces picked up at the farthest points, in a line from N.W. to S.E., were about 25 paces apart and weighed close to an ounce. The cloud’s direction was from N.E. to S.W., as described by Mr. Clarke, who is a gentleman of intelligence and established credibility.
Mr. Brown and I went to the spot this morning, and we all helped in picking up 15 to 20 pieces, which I have by me at the moment, and from which I send you a sample, which I hope will be passed over to Dr. Gibson so that he can determine what kind of flesh it is. The flesh and liver are in perfect condition at the moment, and the latter part I will put in alcohol for future inspection by the curious.”
A similarly grisly rain is said to have taken place the previous February 15 in Simpson County, North Carolina, were pieces of flesh, liver, brains, and blood, all looking fresh, fell out of a red cloud and splattered over an area of thirty feet wide and 250 to 300 yards long.
According to the San Francisco Herald of July 24, 1851, blood and flesh, with pieces ranging in size from a pigeon’s egg to a small orange, descended in a two- to three-minute shower on an Army station at Benicia, California, covering a spot of ground thirty yards wide and 300 yards long.

One Sunday in July 1869, blood was said to have fallen from the sky and landed on two acres of a cornfield near Los Angeles. Those who saw it — a funeral party that included members of the clergy — had no doubt that the substance was blood. It was not only a thick, vivid red, but it also contained hairs and organ fragments.
It’s easier to believe that stories like these are entirely fabricated than it is to believe that the fallen material was actually water colored by dust or plant matter. After all, we have rational, educated witnesses here.
Furthermore, these are not the only such stories. During a storm on October 16 and 17, 1846, a vividly red and bloodlike rain caused widespread terror among French witnesses.
A chemist who examined the material under a microscope noticed a “large quantity of corpuscles.” More specifically, the Italian Meteorological Bureau identified the red stuff that rained on Messignadi, Calabria, as bird’s blood.
On March 8, 1876, “flakes of meat” came down out of the sky to land on a Bath County, Kentucky, field, and one brave witness tasted a “perfectly fresh” sample. According to Scientific American (March 1876), it reminded him of “mutton or venison.”
This widely publicized occurrence sparked considerable debate and quickly fell victim to two conventional, contradictory, and unconvincing explanations.
