The Green Children of Woolpit: A Medieval Mystery and Its Explanations

In a quiet English village called Woolpit, in the county of Suffolk, something happened one day in the twelfth century that the villagers could not explain. At the edge of the fields, where old trenches had been dug to trap wolves, farmers found two children — a boy and a girl — trembling in bewilderment. What was strange was not only their clothes or their unknown tongue, but the color of their skin: it was entirely green.

The tale may sound at first like pure invention, but it is no folk legend of unknown origin. Two respected medieval writers recorded it, decades after the event, and treated it as something that had genuinely occurred. And that is where the real mystery begins.

Two serious sources for a strange tale

We know the story of the Green Children from two English chroniclers of the late twelfth century. The first is Ralph of Coggeshall, a Cistercian abbot who wrote in his English Chronicle and said he had heard the account from the knight Richard de Calne, who took the children into his own household. The second is William of Newburgh, a historian known for his caution and skepticism, who admitted he had long hesitated to believe the story, but that the weight of witnesses moved him to write it down.

The existence of two relatively independent sources — one of them a critical historian — makes it hard to dismiss the story as sheer fantasy. That does not mean every detail is accurate, but it does mean that some event — two strange children appearing in Woolpit — had a basis that people passed on in earnest.

What happened to the children?

The account says the villagers brought the children to the house of Sir Richard de Calne. The pair refused every food offered to them and wept with hunger, until bundles of green beans, still on their stalks, were fetched — and they devoured them eagerly. They lived on beans alone for a time, before gradually learning to eat bread and other food. As time passed, the green color faded from their skin, and they came to look like any ordinary children.

But the boy was frail and sickly; he fell ill and died after a short while. The girl, however, survived and grew up. She was baptized a Christian, learned English, and is said to have later married and settled in the region. And once she could speak, she is reported to have tried to describe where the two of them had come from.

The 'Land of Saint Martin'

When the girl was asked about her homeland, she said the two of them came from a land its people called the 'Land of Saint Martin,' where everything was green and the people were green like them, and where the sun did not shine brightly but a dim, twilight glow prevailed. She told how she and her brother had been tending their father's flock when they heard a great sound like bells, and suddenly found themselves at the Woolpit trenches, dazzled by the light and unable to return.

These uncanny details are what have sometimes led the story to be filed under fairy lore, or even, in modern writing, 'visitors from another world.' But before leaping to the supernatural, it is wise to ask: is there a real explanation that accounts for all these elements — the green skin, the unknown language, the strange diet, and the tale of a green land?

The likeliest explanation: migrants and malnutrition

The explanation that convinces most modern scholars blends history and medicine. In the twelfth century, England was home to communities of immigrants, among them Flemish settlers (from Flanders) brought over for work, who then suffered violent persecution under King Henry II and were crushed in a battle near Suffolk in 1173. It is plausible that the children were Flemish orphans, lost after their parents were killed, who wandered through the forests until they reached Woolpit. This would explain their 'unknown' tongue — Flemish — which the English villagers could not understand.

As for the green color, there is a well-known medical explanation. Severe malnutrition and iron deficiency cause a form of anemia once called 'the green sickness' (chlorosis), which can give the skin a pale greenish tint. Two starving, lost children living on wild plants would naturally develop it. This is confirmed by the fact that their greenness vanished once their diet improved — exactly what you would expect from a nutritional condition, not a supernatural nature. Their fixation on beans fits too: beans were a common crop that runaway children could recognize and live on.

And the dimly lit 'Land of Saint Martin' may be a garbled memory of a real village (there were towns named for Saint Martin), or a description of being lost in a tunnel or dense forest before emerging into daylight. Gather the threads and the 'fairy tale' becomes a familiar human tragedy: two refugee children, traumatized and ill, trying to tell people about their lost world as best they could.

Why does the story still fascinate?

Even with this convincing explanation, the tale of the Green Children remains gripping, because it lives in that grey zone between history and imagination. We have no certain proof that settles every detail, and some elements may have been added or embroidered through retelling. But its core — two real, strange children — seems solid. That is what makes it a perfect model of how a legend works: it takes an obscure factual kernel and clothes it in the marvelous, filling the gaps people cannot explain.

The Green Children of Woolpit remind us that history is not always clear and documented, but full of gaps that imagination fills. And perhaps the deeper lesson is that behind every old 'miracle' lies a human story — of hunger, of refuge, and of two lost children trying to find a new home in a world that did not understand them.
