Stories involving the mythical wizard Merlin have been popular since the Renaissance, especially with the renewed interest in the legend of King Arthur in modern times. As noted by Arthurian scholar Alan Lupack, "numerous novels, poems and plays center around Merlin. In American literature and popular culture, Merlin is perhaps the most frequently portrayed Arthurian character."[1]
According to Stephen Thomas Knight, Merlin embodies a conflict between knowledge and power: a symbol of wisdom in the first Welsh stories, he became an advisor to kings in the Middle Ages, and eventually a mentor and teacher to Arthur and others in the works around the world since the 19th century.[2] While some modern authors write about Merlin positively through an explicitly Christian worldview,[3] New Age movements see Merlin as a druid who accesses all the mysteries of the world,[4] and Francophone artistic productions since the end of the 20th century have tended to avoid the Christian aspects of the character in favor of the pagan aspects and the tradition sylvestre (attributing positive values to one's links to the forest and wild animals), thus "dechristianizing" Merlin to present him as a champion for the idea of return to nature.[5] Diverging from his traditional role in medieval romances, Merlin is also sometimes portrayed as a villain.[1] As Peter H. Goodrich wrote in Merlin: A Casebook:
Merlin's primary characteristics continue to be recalled, refined, and expanded today, continually encompassing new ideas and technologies as well as old ones. The ability of this complex figure to endure for more than fourteen centuries results not only from his manifold roles and their imaginative appeal, but also from significant, often irresolvable tensions or polarities [...] between beast and human (Wild Man), natural and supernatural (Wonder Child), physical and metaphysical (Poet), secular and sacred (Prophet), active and passive (Counselor), magic and science (Wizard), and male and female (Lover). Interwoven with these primary tensions are additional polarities that apply to all of Merlin's roles, such as those between madness and sanity, pagan and Christian, demonic and heavenly, mortality and immortality, and impotency and potency.[6]
Since the Romantic period, Merlin has been typically depicted as a wise old man with a long white beard, creating a modern wizard archetype reflected in many fantasy characters,[7] such as J. R. R. Tolkien's Gandalf[8] or J. K. Rowling's Dumbledore,[9] that also use some of his other traits. Things named in honour of the legendary figure have included asteroid 2598 Merlin, the British company Merlin Entertainments, the Merlin handheld console, the literary magazine Merlin, the metal band Merlin, and more than a dozen different British warships each called HMS Merlin. He was one of eight British magical figures that were commemorated on a series of UK postage stamps issued by the Royal Mail in 2011,[10] and one of the three Arthurian figures (along with Arthur and Morgan) commemorated on the gold and silver British pound coins issued by the Royal Mint in 2023.[11] Merlinia, the Ordovician trilobite, is also named after Merlin. The name is given in memory of the legends of Wales, in which broken tail parts of trilobites were identified as butterflies turned to stone by Merlin.[12][13]
