Gwyn ap Nudd: The Fairy King Under Glastonbury Tor and the Hunt of Souls

Glastonbury Tor rises out of the Somerset flats like an argument for the invisible: a single conical hill, terraced with enigmatic ridges, crowned by a roofless tower, visible for twenty miles across country that was once sea-marsh and island. Christian legend planted its holiest things at the foot of it. But the Tor itself, the hill as hill, belonged in the older reckoning to another proprietor entirely, and the medieval Welsh texts name him without embarrassment: Gwyn ap Nudd—Gwyn, son of Nudd, White One son of Mist—king of Annwn, the Welsh otherworld, and king of the Tylwyth Teg, the Fair Folk. His court is inside the Tor; his hounds are the white, red-eared Cŵn Annwn, whose cry in the night sky foretells death; his office, fixed by one of the strangest sentences in medieval literature, is to restrain the devils of the abyss lest they destroy the world; and his hunt rides to gather souls. Arthur's Avalon, the saints' abbey, the pilgrims' holy wells all cluster at the hill's foot—and the hill's inside remained, in the imagination of a thousand years, the palace of the fairy king: the one address in Britain where the Christian heaven and the pagan deep stand on the same few acres, negotiating.

The Saint on the Hilltop

The negotiation is recorded. The medieval life of Saint Collen tells how that austere hermit, living in a cell at the Tor's foot, twice overheard men speak of Gwyn ap Nudd as king of Annwn and of the fairies, and rebuked them: such beings were devils. The men warned him he would be summoned. He was. A messenger came to the cell, once, twice, thrice, bidding him meet the king on the hilltop at noon; and Collen at last climbed the Tor—carrying, under his robe, a flask of holy water. On the summit he found what had never been there before and was never there after: a castle, the fairest he had seen, ranked with hosts, musicians, comely youths and maidens, and the king enthroned amid a feast, who welcomed the saint courteously and offered him meat and wine. Collen refused with the great line the tradition kept: "I will not eat of the leaves of the trees." The king pressed him further, showing the splendor of his court's liveries, red on one side and blue on the other; and the saint answered that the red was the burning and the blue the freezing—the colors of hell's two torments—and dashed the holy water over the assembly: whereupon castle, feast, hosts, and music vanished in an instant, leaving the old man alone on the windy summit among the tussocks.

The Church told this tale as a victory, and the reader should notice what kind of victory it records. Collen refutes nothing; he dispels. The court withdraws before the holy water as a tide withdraws—and the Tor remains the Tor, with the fairy king's tenancy unrevoked in the very telling, for it is the saint's biographer himself who has preserved, in loving detail, the splendor of the court, the courtesy of the king, and the fact that the summons was thrice-sent and honored. The legend's deep content is a treaty misfiled as an exorcism: the old sovereignty of the hill met the new sovereignty of the cell at noon on the summit, exchanged formal defiances—and both remained in residence. The abbey rose at the foot; the tower of Saint Michael, hell's great treader-down, was set precisely on the summit—and the tower's church fell in an earthquake and stands roofless to this day, a hollow gateway on a hollow hill, through which the equinox sun and the tourists pass equally. Whoever holds the freehold, the architecture is still arguing.

The Huntsman and the Restrained Abyss

Who is Gwyn? The oldest Welsh materials give him three offices, and together they make one of the most remarkable figures in the islands' mythology. He is the psychopomp huntsman: in the old poem of the Black Book of Carmarthen he speaks as the gatherer of the battle-dead—I have been where the warriors of Britain were slain; I come from the field, their escort to the grave—and his white, red-eared hounds, heard yelping high and faint on winter nights, were known the length of Wales as the death-pack whose cry meant a soul's departure: the Welsh chapter of that great spectral commonwealth of night-hunts whose broader musters we have followed in the lore of the Wild Hunt. He is the eternal combatant: by the tale preserved in Culhwch and Olwen, Gwyn and his rival Gwythyr fight for the maiden Creiddylad every first of May until Doomsday—the year's own two kings, dark half and bright half, locked in a duel that is also a calendar; whoever holds her at the end of days shall keep her. And he is—the strangest office, stated flatly in the same medieval text—the warden of the abyss: God, it says, has set in Gwyn the nature of the devils of Annwn, lest this world be destroyed: he restrains them; he is the containment of the underworld personified, the dark king whose kingship is precisely what keeps the dark governed. Not a devil, then, but the governor of devils by divine appointment—paganism's deep sovereign given, by the Christian scribe himself, a portfolio in the new administration.

The Esoteric Reading: The Hollow Hill at the Heart of the Holy

Assemble the whole figure and the Tor's strange double tenancy becomes a doctrine—perhaps the central doctrine of the western mysteries, written in Somerset landscape. The deep is royal, not demonic. Gwyn is what the pre-Christian world knew and the wiser strands of the Christian world kept on the books: that the underworld of the soul—the dead, the dark, the wild hunt of the instincts—is not a mob but a kingdom, with a king whose nature partakes of what he governs and whose governance is the world's safety. Depose him—declare the deep mere devilry, as Collen tried—and you do not abolish the abyss; you merely unseat its warden. The medieval sentence is exact where whole theologies are clumsy: the dark powers are set under a dark king lest the world be destroyed. The health of the world, and of any soul, depends not on the abolition of Annwn but on the legitimacy of its government.

Hence the May-fight: the dark king is not to be destroyed but balanced—met every year, at the hinge of the seasons, by his bright twin, neither ever finally victorious until the end of all calendars; the soul's year turns on the honest annual battle, not on a hoped-for extermination. Hence the hounds: the deep sends its escort for whatever in us dies, and the cry of the Cŵn Annwn overhead—dreadful, high, and faint—is not an attack but a funeral in progress; the old Welsh listened and said prayers, which is the correct response to the sound of the psychopomp pack in any century. And hence, above all, the geography: the fairy king's palace and the saints' sanctuary share one hill, where the hawthorn of Arimathea flowers by the red spring at the Tor's foot and the whole later mythology of Avalon and the passing of Arthur gathered at the same address. The esoteric tradition has always read that convergence as a map rather than a coincidence: the holiest ground of the daylight faith stands directly upon the court of the deep king—the sanctuary is built at the mouth of the hollow hill, and draws its unusual grace precisely from what it stands over. Glastonbury is the western statement of the universal law: where the veil is thin, both kingdoms hold court.

Wales kept his memory in its own registers long after the romances forgot him. The folk of the northern valleys said Gwyn held court on certain hills each New Year's Eve; the fairy islands of the lakes were his provinces; and the very phrase the old texts use for his people—the Fair Family—carries the double courtesy the Welsh always paid the powers under the hills: flattery and precaution in one breath. Even his father Nudd, the Mist, descends from Nodens of the silver hand, a god with a real temple whose ruins still stand above the Severn—so that Gwyn's pedigree runs unbroken from Romano-British altar to medieval poem to the tourist path up the Tor: three religions deep, and never once evicted.

The Tor is National Trust grass now; the terraces—prehistoric field-systems, or a processional maze, the archaeologists debate—wind up to the roofless tower, and on May morning and midsummer the hill carries pilgrims of every persuasion, most of whom could not name Gwyn ap Nudd and all of whom climb, visibly, as if expected. The white hounds have not been reliably reported for some generations; the winter skies over the levels still produce, in the right wind, a high yelping that the rational identify as wild geese, which is what the rational identified it as in 1400 also. And the old arrangement holds. The saint's water dispelled the visible court; the invisible one kept its lease; and the tower stands open at the summit like a door neither side chose to close—through which, at the year's hinges, the light comes level across the drowned country, and something under the hill, royally patient, keeps the abyss in order and waits for the first of May.
