Morgan le Fay first steps into Arthur’s mythos in Geoffrey of Monmouth’s Vita Merlini, written in 1150. Here, she is the eldest of the nine sisters who rule the ethereal isle of Avalon and is a powerful healer. This Morgan could shape shift into animals, manifest as a crone or a maiden and fly. She’s also clever – a skilled mathematician and astronomer. Arthur’s men trust Morgan and take their mortally injured king to her to be healed. Geoffrey’s portrayal of her is sympathetic and he creates a strong, rounded female character.
In Chrétien de Troyes’ French romantic interpretation of the myth, she is presented as Arthur’s sister and described as ‘Morgan the Wise’. She is no longer the ruler of the island, but is in a relationship with its ruler, Lord Guigomar. And so her power starts to be subsumed, manipulated by medieval writers, reluctant to believe a woman could be knowledgeable, powerful or clever.
She remains a relatively benign character until Arthur’s tale is dramatically rewritten in the French Vulgate Cycle (c. 1210–30), thought to be composed by fundamentalist Cistercian monks. Cistercians were crusaders, dedicated to eradicating heretics. They despised women – some even argued against the existence of a female soul – and used the Arthurian tales as propaganda for the Christian religion. Morgan embodied everything that terrified them about the old forms of worship – a knowledgeable, gifted woman, unashamed of her flesh and desires, existing in a society that acknowledged a female presence. They twisted the benevolent character of Morgan Le Fay into a more sinister seductress and obsessive witch.
Using her looks and sexuality, she persuades Merlin to teach her the dark arts. She exposes Guinevere’s affair with Lancelot and later tries to seduce the knight. In the order’s later works, Morgan’s character becomes more overtly evil: she uses her powers to steal the magical sword Excalibur and its scabbard to use against Arthur and plots his downfall, only to be thwarted by the new witch Ninianne, the Lady of the Lake. However, at the end of Vulgate Cycle, Morgan is one of the ladies who escort Arthur on his final trip to Avalon.
By 1485, when the definitive Arthur book, Le Morte d’Arthur by Thomas Malory, appears, the Cistercian template is set. Malory’s Morgan is even more reductive. There is no affair that initiates her conflict with Guinevere; instead she’s just a fundamentally wicked person, malevolent, Arthur’s nemesis, a mistress of the dark arts, manifesting the medieval world’s fear of the knowledge and power of women.
In Germany, the Malleus Maleficarum (Hammer of Witches) was about to be published near-simultaneously and these books helped to whip up anti-magic fervour and presaged a spike in UK witch trials. One last vestige of Morgan’s earlier incarnation remains – she is permitted to transport Arthur’s body to Avalon.
Morgan has remained a powerful figure in literature – she appears in Italian Renaissance poems, French literature and English writer Edmund Spenser’s epic poem The Faerie Queen. She has smouldered on the big screen, memorably portrayed by Helen Mirren in Excalibur (1981).
Her character is strong enough to bear endless reworking. The image of a sexually confident woman, clever, and gifted with magical healing abilities has been reimagined from benevolent to evil, yet still retains its power. Medieval authors turned Morgan into an evil, vengeful caricature – the only way they could deal with her independence, her power, her sexuality.
