An arm clothed in white samite rises from the still water of a lake, holding a sword. This image — the Lady of the Lake offering Excalibur to King Arthur — is one of the most famous in the Arthurian legend. At the end of the story, the same arm rises again to catch the sword when it is thrown back. Between these two moments, the Lady of the Lake appears again and again: raising the infant Lancelot beneath her waters, protecting Arthur against his enemies, enchanting Merlin and imprisoning him forever, and finally carrying the dying king to Avalon.
The Lady of the Lake is not one person but many. She goes by several names — Viviane, Nimue, Niniane, Nymenche — and in some versions there are several Ladies of the Lake. She is a fairy enchantress, a figure from the Otherworld whose powers are older than Arthur’s kingdom.
Raising Lancelot
The Lady of the Lake first appears in literature as the foster-mother of Lancelot. In the German Lanzelet of Ulrich von Zatzikhoven (c. 1200), based on a lost French source, a water-fairy carries off the infant Lancelot and raises him in her kingdom of maidens, an island where it is always spring.
The French Vulgate Lancelot (c. 1220) tells the story in detail. Lancelot’s father, King Ban of Benwick, was driven from his castle by an enemy and died of grief watching it burn. His queen, Elaine, set the baby down by a lake to comfort her husband, and when she turned back, a lady was holding the child — and then she vanished with him into the lake.
The lake was an illusion, concealing the lady’s realm. There, the Lady of the Lake raised Lancelot without telling him his name or parentage. That is why he is called Lancelot du Lac, “Lancelot of the Lake.” When he was eighteen, she brought him to Arthur’s court to be knighted, and gave him a magic ring that could reveal enchantments. See Lancelot.
In the Vulgate, this Lady of the Lake is called Niniane or Viviane. She learned her magic from Merlin.
The Gift of Excalibur
In Malory’s Le Morte d’Arthur, the sword Arthur pulled from the stone breaks in a fight with King Pellinore. Merlin leads Arthur to a lake. In the middle of the lake, Arthur sees an arm clothed in white samite holding a fine sword. A damsel walks across the water toward them. She is the Lady of the Lake. Merlin tells Arthur to ask her for the sword.
The Lady says the sword is hers, and that she will give it to him if he will give her a gift when she asks for it. Arthur agrees. He rows out in a barge and takes the sword and its scabbard from the hand, which sinks back beneath the water.
Merlin asks Arthur which he prefers, the sword or the scabbard. Arthur says the sword. Merlin tells him he is foolish: the scabbard is worth ten of the sword, for while he wears it he will never lose blood, however badly he is wounded. See Excalibur.
The Lady’s Gift
Later, the Lady of the Lake comes to Arthur’s court to claim her promised gift. She asks for the head of Sir Balin, a knight who, she says, killed her brother; Balin, in turn, accuses her of killing his mother. Before Arthur can answer, Balin cuts off her head. Arthur is horrified. This Lady of the Lake is killed early in Malory’s story, and Nimue takes her place.
Nimue and Merlin
Nimue (also Nyneve or Vivien) is the Lady of the Lake who brings about Merlin’s downfall. The old wizard falls hopelessly in love with her. She agrees to his company only if he teaches her his magic. When she has learned enough, she uses his own spells to imprison him forever — in a cave, a stone, a tower of air, or a tree.
This story is told in Merlin and Nimue: The Enchantment of the Wizard.
Nimue as Arthur’s Protector
Despite her treatment of Merlin, Nimue becomes one of Arthur’s most loyal protectors in Malory’s work. She saves him several times from the plots of his half-sister Morgan le Fay:
- When Morgan sends Arthur a magnificent cloak, Nimue warns him to make the messenger put it on first. The damsel does so, and is burned to ashes by its poison.
- When Morgan steals Excalibur and gives it to her lover Accolon to fight Arthur, Nimue arrives during the fight and uses her magic to make Excalibur fall from Accolon’s hand. Arthur recovers it and defeats Accolon.
- She rescues Sir Pelleas, a knight dying of unrequited love, and marries him herself.
She also clears Guinevere of the charge of poisoning Sir Patrise with an apple, by revealing the true murderer.
The Return of Excalibur
At the end of the legend, after the Battle of Camlann, the dying Arthur orders Sir Bedivere to throw Excalibur into the lake. Twice Bedivere hides it, unable to bear throwing away such a treasure. The third time, he throws it, and an arm rises out of the water, catches it by the hilt, brandishes it three times, and draws it under the water (see The Death of Arthur).
The Barge to Avalon
Then a barge arrives to take Arthur to Avalon. On it are three queens — Morgan le Fay, the Queen of Northgales, and the Queen of the Waste Lands — and with them is Nimue, the chief Lady of the Lake.
So the Lady of the Lake is present at both the beginning and the end of Arthur’s reign: she gives him the sword that makes him king, and receives it back when he dies.
Origins
The Lady of the Lake belongs to a long Celtic tradition of water-fairies and Otherworld women:
- In Welsh tradition, lakes were entrances to the Otherworld. The story of the Lady of Llyn y Fan Fach, a fairy woman who emerged from a lake in Carmarthenshire to marry a farmer and whose sons became famous physicians, is a well-known example.
- In Irish myth, supernatural women often dwelt in lakes, rivers, or beneath the sea, and the Otherworld could be reached through water.
- Offerings of swords and other weapons were thrown into lakes, rivers, and bogs in Bronze Age and Iron Age Britain and Europe, apparently as gifts to the gods or spirits. Hundreds have been found by archaeologists, such as at Llyn Cerrig Bach in Anglesey. The image of Excalibur being returned to the lake may preserve a memory of this ancient practice.
The name Viviane may derive from a Celtic name related to Coviana or to the Irish sea-goddess Niamh or the river-goddess Boann. Nimue may come from Mnemosyne, the Greek goddess of memory, or from the name of a Welsh river-goddess.
The Lady Today
The Lady of the Lake has been reimagined many times. In Tennyson’s Idylls of the King, Vivien is a scheming seductress. In Marion Zimmer Bradley’s The Mists of Avalon, Viviane is the high priestess of the goddess on Avalon. In Monty Python and the Holy Grail (1975), a peasant memorably objects: “Strange women lying in ponds distributing swords is no basis for a system of government!” — a joke that depends on the image being instantly recognizable.
