Blood rain
Encyclopedia
Blood rain or red rain is a phenomenon in which blood is perceived to fall from the sky in the form of rain. Cases have been recorded since Homer
's Iliad
, composed ca eighth century BC, and are widespread. Before the 17th century it was generally believed that the rain was actually blood. Literature mirrors cult practice, in which the appearance of blood rain was considered a bad omen, and was used as a tool foreshadowing events, but while some of these may be literary devices, some occurrences are historic.
Recorded instances of blood rain usually cover small areas. The duration can vary, sometimes lasting only a short time, others several days. By the 17th century, explanations for the phenomenon had moved away from the supernatural and attempted to provide natural reasons. In the 19th century blood rains were scientifically examined and theories that dust gave the water its red colour gained ground. Today, the dominant theories are that the rain is caused by red dust dissolved in the water (rain dust
), or due to the presence of micro-organisms. Alternative explanations include sunspots and aurora
e, and in the case of the red rain in Kerala
in 2001, dust from meteorites and extraterrestrial cells in the water.
's Iliad, in which Zeus
twice caused a rain of blood, on one occasion to warn of slaughter in a battle. The same portent occurs in the work of the poet Hesiod
, writing around 700 BC; The author John Tatlock suggests that Hesiod's story may have been influenced by that recorded in the Iliad. The first-century Greek biographer Plutarch
also recounts a tradition of a rain of blood during the reign of Romulus
, founder of Rome. Roman authors Livy
and Pliny
record some later cases of blood rain, with Livy describing it as a bad portent.
Unusual events such as a rain of blood were considered bad omens in Antiquity, and this belief persisted through the Middle Ages
and well into the Early modern period
. Throughout northern and western Europe there are many cases of rains of blood which were used by contemporary writers to augur bad events: the Anglo-Saxon Chronicle
records that in 685, "there was a bloody rain in Britain. And milk and butter were turned to blood. And Lothere, king of Kent, died". Tatlock suggests that although the Chronicle was written long after the events, it may have basis in historical truth. He notes that although the rain may seem to be foreshadowing the death of Lothere, medieval chroniclers often noted unusual occurrences in their works "merely for their general interest". Gregory of Tours
records that in 582 "In the territory of Paris there rained real blood from the clouds, falling upon the garments of many men, who were so stained and spotted that they stripped themselves of their own clothing in horror". Although the work of Geoffrey of Monmouth
, a 12th-century writer who popularised the legends of King Arthur
, is regarded as "fantastical" rather than reliable, he too notes the occurrence of blood rain. This event was further expanded on by Layamon
in his poem Brut (written around 1190), who described how blood rain was one of several portents, and which itself led to destruction:
Many works which record occurrences of blood rain, such as that of Layamon, were written significantly after the event was supposed to have taken place. The 14th-century monk Ralph Higden in his work, the Polchronicon, recounts that in 787 there was a rain of blood, perhaps intended by the author as an indication of the coming Viking
invasion. Written in the 12th century, the Book of Leinster
records many sensational events, including showers of silver; it records a shower of blood in 868.
In the work of William of Newburgh
, a rain of blood proves the drive and determination of Richard the Lionheart
. According to William of Newburgh
, a contemporary chronicler, in May 1198 Richard and the labourers working on the castle were drenched in a "rain of blood". While some of his advisers thought the rain was an evil omen, Richard was undeterred:
In Germany, a shower of blood was one of several portents for the arrival of the Black Death
in 1348–1349. The phenomenon gained exposure to a wide audience in the 16th century, during the Renaissance
, when it was used as an example of the power of God; a form of literature using prodigies such as blood rain as cautions against immorality proliferated across Europe having originated in Italy. In Germany, such works were particularly popular amongst Protestants. Although unusual events such as rains of blood were still treated with superstition, often as demonstrations of godly power, Nicolas-Claude Fabri de Peiresc
(1580–1637) was one of the few who proposed natural causes; after hearing of a bloody rain in Aix-en-Provence
, he suggested it was caused by butterflies. Although his theory would later be rejected, he helped the likes of Pierre Gassendi
and René Antoine Ferchault de Réaumur
to lay the foundations for removing superstition from explanations of the phenomenon.
In Europe, there were fewer than thirty recorded cases all together of blood rain in the 13th, 14th, and 15th centuries. There were 190 instances across the 16th and 17th centuries; there was a decline in the 17th century when only 43 were recorded, but this picked up again with 146 in the 19th century. There is little literature on the subject of blood rain, although it has gained the attention of some naturalists. The phenomenon received international coverage in 2001, after red rain fell in Kerala
, India.
rejected the idea and instead suggested that the red rain may be caused by "ex aliqua contagion terrena", "from some earthly contagion". The two cases in the Iliad are explained by Heraclitus
as simply red-coloured rain rather than literally blood; however, a later scholiast (a critical or explanatory commentator) suggests that it was precipitation of blood which had evaporated earlier: after a battle, blood would flow into nearby water courses, evaporate, and then fall as rain. This explanation demonstrating unfamiliarity with the properties of distillation
was echoed by Eustathius of Thessalonica
, a 12th-century archbishop.
Tatlock, in a study of some medieval cases of blood rain, notes that the medieval cases of blood rain "agree well" with their classical counterparts. Although there are variables – for example the rain sometimes lasted only for a short period, while on other occasions it can last days – they were widely considered to be bad omens, and warnings of events to come. He also suggests that the phenomenon may only be recorded in small areas because the colour of the rain would not always be noticed, and may only be obvious against pale backgrounds. In the classical period, events such as a shower of blood was seen a demonstration of godly power; in the medieval period, Christians were less inclined to attribute the phenomenon to such reasons, although followers of nature-religions
were happy to do so.
In the 19th century, there was a trend towards examining events such as rains of blood more scientifically; Ehrenberg conducted experiments at the Berlin Academy, attempting to recreate "blood rain" using dust mixed with water. He concluded that blood rain was caused by water mixing with a reddish dust mostly composed of animal and vegetable matter. He was unclear on the origin of the dust, stating that it lacked the characteristics of African dust which might have indicated it came from the Sahara Desert. Instead, he suggested that the dust came from dried swamps where it was picked up by violent winds and would later fall as rain. This explanation has persisted, and the Academic Press
Dictionary of Science and Technology (1992) attributes the colour of blood rain to the presence of dust containing iron oxide
.
Other reasons for blood rain aside from dust are sometimes given. Schove and Peng-Yoke have suggested that the phenomenon may be connected to sunspot
s and aurora
e. When red rain fell in Kerala, dust was the suspected cause. Alternative theories included dust from a meteorite and extraterrestrial cells in the water. These were later dismissed. The particles causing the red colour in Kerala were "morphologically similar" to algae and fungal spores.
