The Powers of Morgan le Fay

Across the many medieval and modern versions of the Arthurian legend, Morgan le Fay is consistently described as the most powerful practitioner of magic in the British Isles. Where Merlin is a prophet and an architect, Morgan is a worker of wonders, a mistress of every art of transformation, healing, and concealment. Her powers are the engine of much of the legend’s action — the means by which Avalon is reached, by which Arthur is wounded, and by which the Round Table is broken.

Healing and the Arts of Medicine

The earliest and most fundamental of Morgan’s powers is the healing art. In the Welsh tradition, she is an hela, a master of the herbs and the arts of the Otherworld. In the Hoianau (the “Hunting of the Boar Trwyth”), she is the one who heals Arthur’s wounds after the great hunt. In Malory’s Le Morte d’Arthur, she is one of the three queens who take the dying Arthur to the Vale of Avalon to be healed. The figure of the three queens — Morgan, the Queen of the North Galés, and the Queen of the Waste Lands — is the medieval Welsh tradition’s otherworld healer preserved in the English text.

Morgan’s healing is not the same as the ordinary medicine of the medieval world. It is the healing of the Otherworld, working with herbs gathered at the time of the full moon, with chants and songs in the ancient languages, and with the magical waters of the sacred springs. It is the healing of wounds that ordinary physicians cannot touch — the deep wounds of battle, the wounds of grief, the wounds of long warfare. In some versions of the legend, Morgan is the only one who can heal the grievous wound that Arthur receives at the Battle of Camlann. The implication is that without Morgan there is no recovery, only death.

This aspect of Morgan’s powers has been emphasized in the modern reinterpretations. In Marion Zimmer Bradley’s The Mists of Avalon, Morgan (Morgaine) is a priestess of the goddess religion, a healer and a keeper of the sacred mysteries. The novel presents her as the inheritor of an ancient tradition of women’s healing, a tradition that the medieval Christian church tried to suppress.

Shapeshifting

The second great power of Morgan is shapeshifting — the ability to take on the form of any creature she chooses.

In the Vulgate Cycle, the great French prose narrative of the early thirteenth century, Morgan is one of the most prolific shape-shifters. She takes the form of a stone by a stream, in order to eavesdrop on a lover’s conversation. She takes the form of an owl, in order to spy on her enemies. She takes the form of a damsel of the court, in order to seduce a knight. She takes the form of a young man, in order to deceive a king.

The shapeshifting of Morgan is closely related to the older Celtic tradition of the fée, the fairy woman, who can take any form she pleases. The Irish and Welsh traditions knew many such women — the Morrígan, the goddess of war, who took the form of a crow; the Welsh Ceridwen, who took the form of a greyhound; the bean sí of Irish folklore, who appeared as a beautiful woman. Morgan belongs to this wider family of Celtic supernatural women.

The medieval church was deeply suspicious of shapeshifting. It was associated in the popular imagination with the demonic, with the succubus, with the wild woman of the night. Yet the church also recognized that the gift of transformation was a divine power, granted only to those who had the second sight. Morgan, in the medieval imagination, occupies a place between the two poles — a powerful figure whose shapeshifting can be used for good or for ill.

The Otherworld and the Paths to Avalon

The third great power of Morgan is the knowledge of the Otherworld — the mystical realm that exists alongside the ordinary world, accessible only to those who know its paths.

Morgan, as the queen of Avalon, knows the paths to the Otherworld. She can travel there at will. She can summon the mist that conceals the sacred island. She can call the magic boat that crosses the sea to the apple isle. In some versions of the legend, she keeps the bridge that connects the world of the living to the world of the dead.

The knowledge of the Otherworld is closely related to the older Welsh tradition of the Annwn, the realm of the dead and the source of magical power. In the Mabinogion, the heroes of the Welsh tradition visit Annwn in search of magical treasures — the cauldron of Branwen, the head of the giant Bendigeidfran, the white sow of the Otherworld. Morgan, as a queen of Annwn, knows the paths and the gates of this world, and can open them for those she chooses.

The Magical Arts

The fourth great power of Morgan is the mastery of the magical arts in general. She is a maker of potions, enchantments, and illusions. She can create salves that heal, balms that deceive, and charms that bind.

In the Vulgate Lancelot, Morgan is responsible for the famous “Lover’s Cup” — a potion that, in the related Tristan tradition, is used to bind Tristan and Isolde in their doomed love. She brews the love potions that set knights and ladies on the path to ruin. She creates the phantoms and illusions that the Vulgate authors used to test the loyalty of Lancelot and other knights.

In some versions, she is a maker of magical armor and weaponry. In the Prose Tristan, she forges the sword of Tristan. In the English and Italian traditions, she creates the magic pavilion of the Round Table’s sister festival. The making of magical objects is a special mark of the fairy woman, and Morgan is a notable example of this tradition.

Prophecy

The fifth great power of Morgan is the gift of prophecy. Where Merlin is the prophet of British destiny in the grand historical sense, Morgan is a prophetess of the particular, who can read the patterns of the present and predict the shape of the future.

In the Vulgate Cycle, she is consulted by Arthur and by her sisters about the future. She foresees the doom of the kingdom. She predicts the fall of the Round Table. She warns of the consequences of Lancelot and Guinevere’s love. The doom she predicts is partly of her own making, in the sense that she is one of the architects of the destruction of the kingdom, but the gift of prophecy is independent of her will. The future is something she can see, even if she cannot avoid her own role in bringing it about.

The Command of the Elements

The sixth great power of Morgan is the command of the elements. She can raise storms, calm the winds, and call lightning. She can darken the sun and bring rain out of a clear sky. She can shake the foundations of castles and cause the sea to rise.

In the Stanzaic Morte Arthur and the English Alliterative Morte Arthure, Morgan is a figure of elemental power. She commands the storm that nearly kills Lancelot. She summons the fog that conceals the battle of Camlann. She rides the storm, a kind of wild witch, a sister of the Norse Loki of the tricksters and the Egyptian Set of the storms. The medieval imagination, steeped in the popular tradition of the witch and the storm-rider, found a great figure in Morgan.

The Theft of Excalibur’s Scabbard

The seventh great power of Morgan, and the most consequential in the legend, is the theft of the scabbard of Excalibur.

In Malory’s telling, Morgan had been a student of Merlin, and had learned enough of the magical arts to be a danger to the king. She knew that the scabbard of Excalibur was the true source of Arthur’s power — that the wearer of the scabbard would never lose blood from a wound. She stole the scabbard from Arthur’s chamber, and in some versions she gave it to her lover, in others she threw it into a deep lake, in others she kept it for herself.

The result, in Malory’s version, is that Arthur, deprived of the protection of the scabbard, bleeds to death at the Battle of Camlann. The theft of the scabbard is the immediate cause of the king’s death, and one of the great symbolic acts of betrayal in the legend. It is also a sign of Morgan’s powers: she is the only one who could have stolen the scabbard, the only one who could have outwitted Arthur and the only one who could have outwitted Merlin.

The Modern Reinterpretations

The modern reinterpretations of Morgan’s powers have tended to emphasize her role as a healer and a priestess, and to de-emphasize her role as a seductress and a destroyer. Marion Zimmer Bradley’s Mists of Avalon (1983) is the founding text of this modern reinterpretation. In Bradley’s novel, Morgan is the great priestess of Avalon, the keeper of the sacred mysteries, the defender of the goddess religion against the Christian patriarchy. Her powers are presented as the inheritance of an ancient matriarchal tradition, a tradition that has been preserved by women through the long centuries of patriarchy.

Mary Stewart’s Crystal Cave trilogy (1970-1973) is another major modern reinterpretation, told from the first-person perspective of Merlin. In Stewart’s version, Morgan is a powerful figure, a sister and an enemy, a woman of great magical power. The BBC television series Merlin (2008-2012) presents Morgan as a tragic villain, the lover of Merlin and the avenger of her father’s death.

The modern fantasy tradition has, in general, restored Morgan to her older role as a healer and a guardian of the Otherworld. The figure of the dark enchantress, the seductress, the witch, has been balanced by the figure of the wise woman, the priestess, the healer. The duality is the essential character of Morgan — and the source of her enduring power in the imagination.

The Symbolism of Morgan’s Powers

The powers of Morgan are the powers of the Celtic Otherworld. She can heal, transform, predict, and command. She is the mistress of the threshold between the worlds. Her powers are not those of the male magician, the worker of celestial magic that comes from above. They are the powers of the female witch, the worker of the chthonic magic that rises from below — from the earth, from the springs, from the standing stones, from the Otherworld.

In Morgan, the medieval and modern world found a figure of almost inexhaustible symbolic resonance. She is the witch and the healer, the mother and the destroyer, the queen of the Otherworld and the architect of the kingdom’s fall. The powers of Morgan are the powers of the wild. The medieval storytellers, who claimed to fear them, kept writing her back into the legend anyway, century after century — which is itself a kind of testimony.
