The green children of Woolpit reportedly appeared in the village of Woolpit in Suffolk, England, some time in the 12th century, perhaps during the reign of King Stephen. The children, brother and sister, were of generally normal appearance except for the green colour of their skin. They spoke in an unknown language, and the only food they would eat was green beans. Eventually they learned to eat other food and lost their green pallor, but the boy was sickly and died soon after the children were baptised. The girl adjusted to her new life, but she was considered to be "rather loose and wanton in her conduct". After she learned to speak English the girl explained that she and her brother had come from St Martin's Land, an underground world whose inhabitants are green.
The only near-contemporary accounts are contained in Ralph of Coggeshall's Chronicum Anglicanum and William of Newburgh's Historia rerum Anglicarum, written in about 1189 and 1220 respectively. Between then and their rediscovery in the mid-19th century, the green children seem to surface only in Bishop Francis Godwin's fantastical The Man in the Moone, in which William of Newburgh's account is reported.
Two approaches have dominated explanations of the story of the green children: that it is a typical folk tale describing an imaginary encounter with the inhabitants of another world, perhaps one beneath our feet or even extraterrestrial, or it is a garbled account of a historical event. The story was praised as an ideal fantasy by the English anarchist poet and critic Herbert Read in his English Prose Style, published in 1931. It provided the inspiration for his only novel, The Green Child, written in 1934.
The village of Woolpit is in the county of Suffolk, East Anglia, about 7 miles (11 km) east of the town of Bury St Edmunds. During the Middle Ages it belonged to the Abbey of Bury St Edmunds, and was part of one of the most densely populated areas in rural England. Two writers, Ralph of Coggeshall (died c. 1226) and William of Newburgh (c. 1136–1198), reported on the sudden and unexplained arrival in the village of two green children during one summer in the 12th century. Ralph was the abbot of a Cistercian monastery at Coggeshall, about 26 miles (42 km) south of Woolpit. William was a canon at the Augustinian Newburgh Priory, far to the north in Yorkshire. William states that the account given in his Historia rerum Anglicarum (c. 1189) is based on "reports from a number of trustworthy sources"; Ralph's account in his Chronicum Anglicanum, written some time during the 1220s, incorporates information from Sir Richard de Calne of Wykes, who reportedly gave the green children refuge in his manor, 6 miles (9.7 km) to the north of Woolpit. The accounts given by the two authors differ in some details.
One day at harvest time, according to William of Newburgh during the reign of King Stephen (1135–1154), the villagers of Woolpit discovered two children, a brother and sister, beside one of the wolf pits that gave the village its name. Their skin was green, they spoke an unknown language, and their clothing was unfamiliar. Ralph reports that the children were taken to the home of Richard de Calne. Ralph and William agree that the pair refused all food for several days until they came across some green beans, which they consumed eagerly. The children gradually adapted to normal food and in time lost their green colour. The boy, who appeared to be the younger of the two, became sickly and died shortly after he and his sister were baptised.
After learning to speak English the children – Ralph says just the surviving girl – explained that they came from a land where the sun never shone, and the light was like twilight. William says the children called their home St Martin's Land; Ralph adds that everything there was green. According to William the children were unable to account for their arrival in Woolpit; they had been herding their father's cattle when they heard a loud noise (according to William, the bells of Bury St Edmunds) and suddenly found themselves by the wolf pit where they were found. Ralph says that they had become lost when they followed the cattle into a cave, and after being guided by the sound of bells eventually emerged into our land.
According to Ralph the girl was employed as a servant in Richard de Calne's household for many years, where she was considered to be "very wanton and impudent". She eventually married a man from King's Lynn, about 40 miles (64 km) from Woolpit, where Ralph said she was still living shortly before he wrote. Based on his research into Richard de Calne's family history the astronomer and writer Duncan Lunan has concluded that the girl was given the name "Agnes", and that she married a royal official named Richard Barre.
Two approaches have dominated explanations of the mystery of the green children. The first is that it is a typical folk tale, describing an imaginary encounter with the inhabitants of a "fairy Otherworld". The second is that it is a garbled account of a real event, although it is impossible to be certain whether the story as recorded is an authentic report given by the children or an "adult invention". His study of accounts of children and servants fleeing from their masters led Charles Oman to conclude that "there is clearly some mystery behind it all [the story of the green children], some story of drugging and kidnapping".
Scholars such as Charles Oman note that one element of the children's account, the entry into a different reality by way of a cave, seems to have been quite popular. Gerald of Wales tells a similar story of a boy who, after escaping his master, "encountered two pigmies who led him through an underground passage into a beautiful land with fields and rivers, but not lit by the full light of the sun". But as a folk tale the story is rather rare; E. W. Baughman lists it as the only example of his F103.1 category of English and North American folk tales: "Inhabitants of lower world visit mortals, and continue to live with them". Martin Walsh considers the references to St Martin to be significant, and sees the story of the green children as evidence that the feast of Martinmas has its origins in an English aboriginal past, of which the children's story forms "the lowest stratum". E. S. Alderson suggests a Celtic connection in a 1900 edition of Notes and Queries: "Green' spirits are 'sinless' in Celtic literature and tradition ... It may be more than a coincidence that the green girl marries a 'man of Lynn.' Here the original would be lein, evil, i.e. the pure fairy marries a sinful child of earth."
Jeffrey Jerome Cohen proposes that the green children are a memory of England's past, and the violent conquest of the indigenous Britons by the Anglo-Saxons followed by the Norman invasion. William of Newburgh reluctantly includes the story of the green children in his account of a largely unified England, which Cohen juxtaposes with Geoffrey of Monmouth's The History of the Kings of Britain, a book that according to William is full of "gushing and untrammeled lying". Geoffrey's history offers accounts of previous kings and kingdoms of various racial identities, whereas William's England is one in which all peoples are either assimilated (in case of the Normans) or pushed to the boundaries (the Welsh, the Scots, and the Picts). According to Cohen the green children represent a dual intrusion into William's unified vision of England. On one hand they are a reminder of the racial and cultural differences between Normans and Anglo-Saxons, especially because of the children's claim to have come from St Martin's Land, named after Martin of Tours; the only other time William mentions that saint is in reference to St Martin's Abbey in Hastings, which commemorates the Norman victory in 1066. But the children also embody the earlier inhabitants of the British Isles, the "Welsh (and Irish and Scots) who [had been] forcibly anglicized ... The Green Children resurface another story that William had been unable to tell, one in which English paninsular dominion becomes a troubled assumption rather than a foregone conclusion." The boy in particular, who dies rather than become assimilated, represents "an adjacent world that cannot be annexed ... an otherness that will perish to endure".
In a modern development of the tale the green children are associated with the Babes in the Wood, who were left by their wicked uncle to die; in this version the children's green colouration is explained by them having been poisoned with arsenic. Fleeing from the wood in which they were abandoned, possibly nearby Thetford Forest, the children fell into the pits at Woolpit where they were discovered. Local author and folk singer Bob Roberts states in his 1978 book A Slice of Suffolk that "I was told there are still people in Woolpit who are 'descended from the green children', but nobody would tell me who they were!"
Other commentators have suggested that the children may have been aliens, or inhabitants of a world beneath the Earth. In a 1996 article published in the magazine Analog, astronomer Duncan Lunan hypothesised that the children were accidentally transported to Woolpit from their home planet as the result of a "matter transmitter" malfunction. Lunan suggests that the planet from which the children were expelled may be trapped in synchronous orbit around its sun, presenting the conditions for life only in a narrow twilight zone between a fiercely hot surface and a frozen dark side. He explains the children's green colouration as a side effect of consuming the genetically modified alien plants eaten by the planet's inhabitants.
Lunan was not the first to state that the green children may have been extraterrestrials. Robert Burton suggested in his 1621 The Anatomy of Melancholy that the green children may have "fell from Heaven", an idea that seems to have been picked up by Francis Godwin, historian and Bishop of Hereford, in his speculative fiction The Man in the Moone, published posthumously in 1638.
Many Flemish immigrants arrived in eastern England during the 12th century, and they were persecuted after Henry II became king in 1154; a large number of them were killed near Bury St Edmunds in 1173. Paul Harris has suggested that the green children's Flemish parents perished during a period of civil strife and that the children may have come from the village of Fornham St Martin, slightly to the north of Bury St Edmunds, where a settlement of Flemish fullers existed at that time. They may have fled and ultimately wandered to Woolpit. Disoriented, bewildered, and dressed in unfamiliar Flemish clothes, the children would have presented a very strange spectacle to the Woolpit villagers. The children's colour could be explained by green sickness, the result of a dietary deficiency. Brian Haughton considers Harris's explanation to be plausible, and the one most widely accepted, although not without its difficulties. For instance, he suggests it is unlikely that an educated local man like Richard de Calne would not have recognised the language spoken by the children as being Flemish.
Historian Derek Brewer's explanation is even more prosaic:
The likely core of the matter is that these very small children, herding or following flocks, strayed from their forest village, spoke little, and (in modern terms) did not know their own home address. They were probably suffering from chlorosis, a deficiency disease which gives the skin a greenish tint, hence the term "green sickness". With a better diet it disappears.
The English anarchist poet and critic Herbert Read describes the story of the green children in his English Prose Style, published in 1931, as "the norm to which all types of fantasy should conform". It was the inspiration for his only novel, The Green Child, written in 1934. A 1994 adaptation of the story written by Kevin Crossley-Holland tells it from the point of view of the green girl.
Author John Macklin includes an account in his 1965 book, Strange Destinies, of two green children who arrived in the Spanish village of Banjos in 1887. Many details of the story very closely resemble the accounts given of the Woolpit children, such as the name of Ricardo de Calno, the mayor of Banjos who befriends the two children, strikingly similar to Richard de Calne. It therefore seems that Macklin's story is an invention inspired by the green children of Woolpit, particularly as there is no record of any Spanish village called Banjos.
In 2002 English poet Glyn Maxwell wrote a verse play based on the story of the green children, Wolfpit (the earlier name for Woolpit), which was performed once in New York City. In Maxwell's version the girl becomes an indentured servant to the lord of the manor, until a stranger named Juxon buys her freedom and takes her to an unknown destination. The green children are also the subject of a 1990 community opera performed by children and adults, composed by Nicola LeFanu with a libretto written by Kevin Crossley-Holland.
