St. Valentine became the patron saint of epilepsy through a combination of miracle legends, medieval beliefs about demonic possession, and a linguistic coincidence rooted in the German language. While nearly everyone knows Valentine as the patron of lovers, his association with epilepsy is centuries old, traceable in Christian art from at least the 1400s and in medical terminology that persisted well into the modern era.
The German Word for “Falling”
The most widely cited explanation is surprisingly simple: the name “Valentine” sounds like the German word “fallen,” meaning “to fall.” Epilepsy was commonly called the “falling sickness” across medieval Europe because of the collapse that often accompanies a seizure. In German-speaking regions, epilepsy was known as “fallende Sucht,” and over time the phonetic overlap between “Valentine” and “fallen” cemented the saint’s name to the disease. The term “St. Valentine’s Malady” (or “St. Veltins-Sucht” in German) became a common way to refer to epilepsy, particularly in Germany and neighboring regions.
Martin Luther himself pointed to this linguistic connection. He argued that the legends of the various saints named Valentine contained no actual references to epilepsy, and that the entire patronage likely grew from the sound of the name rather than from any documented miracle. Whether or not Luther was entirely right, the etymological theory remains the explanation most historians find persuasive.
A Healing Legend Added Later
There is a story in Valentine’s hagiography that he demonstrated the truth of Christianity by healing a person with epilepsy. However, scholars who have traced the development of Valentine’s legend believe this episode was a later addition, inserted after the saint had already become associated with the condition. In other words, the miracle story may have been created to justify a connection that already existed for other reasons.
This kind of retroactive storytelling was common in medieval saint cults. Once a saint became linked to a disease, whether through wordplay, local tradition, or folk belief, hagiographers would often add healing miracles to the official record to formalize the connection. The epilepsy miracle in Valentine’s legend follows that pattern. It does, however, explain why Valentine is frequently depicted in art with a crippled or convulsing child at his feet.
Why Saints Were Invoked for Epilepsy
For most of recorded history, epilepsy was considered untreatable by medicine. Even though the ancient Greek physician Hippocrates proposed around 400 BC that epilepsy was a brain disorder, that naturalistic view didn’t gain real traction until the 1700s and 1800s. For the roughly two thousand years in between, seizures were overwhelmingly understood as supernatural events: curses, divine punishment, or demonic possession.
Because no earthly cure existed, people turned to saints as intercessors who could petition God on their behalf. A cult of prayer and pilgrimage grew around St. Valentine specifically, spreading across Europe. Families of people with epilepsy would pray to Valentine, visit churches holding his relics, and hope for miraculous relief. This was not unique to Valentine. Several saints were invoked for epilepsy, including St. Vitus and St. John, but Valentine’s association proved the most durable.
Three Valentines, One Patronage
The history is complicated by the fact that there were multiple saints named Valentine. The two most famous are Roman martyrs from the third century, but a third Valentine, a bishop of Passau in Bavaria who lived around 470 AD, also became associated with epilepsy. Because all three shared the same name, and because the German linguistic connection applied equally to all of them, their identities blurred together in popular devotion. The Bavarian Valentine’s proximity to German-speaking communities likely helped strengthen the “fallen/Valentine” wordplay and spread it further.
Epilepsy in Christian Art
One of the most tangible records of this patronage comes from six centuries of Christian artwork. A study cataloging depictions of St. Valentine found 143 images showing people with apparent epilepsy characteristics alongside the saint. These artworks span from the 15th century to the present day and include people of all ages: 17 infants, 35 children, 7 adolescents, and 84 adults, with more males than females across all social classes.
Researchers who analyzed the depicted seizure types identified what appear to be infantile spasms, tonic seizures (where the body stiffens), atonic seizures (sudden loss of muscle tone), and various postictal states, the period of confusion or exhaustion after a seizure. The art essentially provides a visual medical record, showing how artists observed and interpreted seizure symptoms across centuries.
In medieval painting specifically, the imagery followed a consistent pattern. Miraculous healing was symbolized by an evil spirit, often depicted as a small demon, black bird, dragon, or dark cloud, being forcibly expelled from the afflicted person by the saint’s blessing. One notable image shows a mother holding her ailing son behind St. Valentine as demons are expelled from the child’s mouth, a scene scholars interpret as a depiction of epileptic spasms being “exorcised.”
From Sacred Disease to Brain Disorder
The patronage of St. Valentine reflects a period when epilepsy sat squarely in the realm of religion rather than medicine. The ancient Greeks had called it “the sacred disease,” and that framing persisted for centuries. During the Middle Ages and Renaissance, European discussions of epilepsy took on intense religious fervor, reinforcing the idea that spiritual intercession was the only path to healing.
As neurology developed in the 18th and 19th centuries and epilepsy was increasingly understood as a condition of abnormal electrical activity in the brain, the practice of invoking saints naturally faded. But the cultural memory persisted in art, in church traditions, and in the historical record. St. Valentine’s dual patronage, of lovers and of people with epilepsy, remains one of the more surprising footnotes in the history of both medicine and religion.
