Hag

Lore & Background

In folklore, a 'Night Hag' or 'the Old Hag' was a nightmare spirit in English and anglophone North American folklore, essentially identical to the Old English mæra and closely related to the Scandinavian mara. According to folklore, the Old Hag sat on a sleeper's chest and sent nightmares; when the subject awoke, they would be unable to breathe or move for a short time. This state is now called sleep paralysis, but in old belief the subject was considered 'hagridden'.

Many stories about hags were used to frighten children into being good. In Northern England, Peg Powler was a river hag who lived in the River Tees, with skin the colour of green pond scum, who would pull children in with her long arms, drown them, and sometimes eat them. Other regional names include Grindylow, Jenny Greenteeth, and Nelly Longarms. In Slavic folklore, Baba Yaga was a hag who lived in the woods in a house on chicken's legs, riding through the forest on a mortar and sweeping away her tracks with a broom; in some folktales three Baba Yagas help the hero.

In Irish and Scottish mythology, the cailleach is a hag goddess concerned with creation, harvest, weather, and sovereignty, ruling the winter months while Brígid rules the summer. In Scotland, The Cailleachan (The Storm Hags) are personifications of destructive elemental powers, active in raising spring windstorms. Hags as sovereignty figures appear in Irish mythology, where the hag represents barren land; when a hero approaches without fear and accepts her, she reveals herself as a young and beautiful goddess.

Reader's Guide

The hag is a multifaceted figure in folklore and mythology, serving as a warning, a supernatural antagonist, and a symbol of transformation. As a nightmare spirit, the Old Hag gave rise to the concept of being 'hagridden', now understood as sleep paralysis, illustrating how folklore can prefigure modern medical understanding. In children's tales, hags like Peg Powler and Jenny Greenteeth functioned as cautionary figures to keep children away from dangerous places such as rivers. The hag also appears as a powerful deity: the cailleach in Celtic myth controls seasons and weather, while the sovereignty hag tests heroes and transforms from hideous to beautiful, representing the land's fertility. The term's etymology from Proto-Germanic *hagatusjon- (of unknown origin) and its connection to the word 'hedge' hint at ancient roots. Using 'hag' to translate non-English terms is contentious due to associations with misogyny. Overall, the hag embodies both malevolence and ambiguous power, appearing across cultures as a witch, goddess, or fairy, and remains a lasting archetype in literature and folklore.

• The word 'hag' is a shortening of the Old English 'hægtesse', meaning 'witch'; Dutch 'heks' and German 'Hexe' are similar shortenings.
• In English folklore, the 'Old Hag' was believed to sit on a sleeper's chest and cause nightmares; this state is now called sleep paralysis.
• In Slavic folklore, Baba Yaga lived in a house on chicken's legs and rode through the forest on a mortar, sweeping away her tracks with a broom.
• In Irish mythology, a sovereignty hag represents barren land and transforms into a young goddess when a hero accepts her hideous form.

Etymology & Linguistic Lineage

The word hag traces back to Middle English as a contraction of hægtesse, an Old English term meaning witch. This shortening pattern mirrors what occurred across the broader Germanic family: Dutch heks derives from Middle Dutch haghetisse, while German Hexe comes from Old High German hagzusa. All of these ultimately descend from the Proto-Germanic root *hagatusjon-, whose precise origin remains uncertain. Scholars have speculated that the first element may connect to the word hedge, though this link is never confirmed. In fairy-tale and folk-tale contexts, the hag overlaps heavily with the crone, and the two labels are frequently treated as interchangeable. However, applying hag as a translation for terms found in non-English or archaic sources has become a point of genuine debate. Critics argue that the word carries baggage of misogyny, making its use in scholarly or creative translation a contested choice rather than a neutral one.

The Night Hag & the Mystery of Sleep

In English and anglophone North American folklore, the Night Hag or Old Hag embodied a terrifying supernatural presence that haunted sleepers. This figure is essentially the same entity as the Old English mæra, a being rooted in ancient Germanic superstition, and is closely related to the Scandinavian mara. According to the old stories, the hag would perch on a victim's chest, flooding their mind with nightmares. Upon waking, the sleeper found themselves locked in place, unable to draw breath or shift a muscle for a brief, agonizing interval. Modern medicine now identifies this experience as sleep paralysis, yet the cultural memory persists: people still speak of being hagridden as though a spectral visitor had truly pressed down upon them. The phenomenon continues to be discussed in popular culture as a kind of paranormal event, and it even features in the 2011 Swedish film Marianne, where the protagonist endures such terrifying nocturnal episodes.

Hags Across the World's Myths

The hag figure appears in remarkably diverse forms across global folklore. In Slavic tradition, Baba Yaga dwells in a forest house that walks on chicken legs, and she travels by riding a mortar while sweeping her tracks with a broom. Though typically a single entity, some tales feature three Baba Yagas who aid a hero with counsel or gifts. In Irish and Scottish mythology, the cailleach serves as a hag goddess governing creation, harvest, weather, and sovereignty. Paired with Brígid, she rules the winter months while Brígid commands summer. In Scotland, the Cailleachan, known as the Storm Hags, embody destructive elemental forces, particularly active during the spring windstorms of the period called A Chailleach. Irish sovereignty tales often cast the hag as a barren land that a hero must approach without fear and love on her own terms; when he succeeds, she reveals herself as a young, beautiful goddess. In ancient Greek religion, the Three Fates, especially Atropos, are frequently depicted as hags.

The Hag in Literature & Cautionary Tales

In children's folklore, the hag often functions as a warning figure. Northern English parents, for instance, told their children that Peg Powler, a river hag with skin the color of green pond scum, lurked in the River Tees. She would seize any child who ventured too close to the water with her long arms, drown them, and sometimes devour them. Similar water-hag figures appear under regional names like Grindylow, Jenny Greenteeth, and Nelly Longarms. In mediaeval and Renaissance literature, the hag evolved into a stock character representing the antithesis of the beautiful lady celebrated in Petrarchan poetry, a tradition particularly developed in Italian burlesque. Charles Kingsley, writing Greek fairy tales for his children, labeled Scylla as Scylla the sea hag. Beyond purely malevolent roles, hags can also be shapeshifting deities like the Morrígan or Badb, who occupy a morally ambiguous space, neither wholly good nor wholly evil, adding a layer of complexity that resists simple categorization.
