Geoffrey of Monmouth composed this epic poem in Latin hexameter some time after his History of the Kings of Britain. He brought together traditions and legends of Myrddin, the mad man of the woods in Welsh legends and poems contained in the Black Book of Carmarthen and the Book of Taliesin, and the prophet Ambrosius from Nennius’s Historia Brittonum. For reasons unknown, he combined these two characters into one. He gave a fleshed out treatment of the man’s prophecies in his earlier book, as well as a short sketch of his discovery by Vortigern’s men.
In this poem, Geoffrey gives the full adult life story of Merlin, a king who goes mad in the brutalities of battle and flees to the Caledonian forest where he lives in seclusion for many years, becoming one with the wild woods, sharpening his skills of prophecy and natural philosophy. His sister and his wife mourn his absence and eventually have him brought back to court, where he is disgusted by society and driven further into his madness, but is forcefully prevented from returning to the woods. After his prophecy about the threefold death of a young man is fulfilled, he is eventually able to return to the woods, where he discusses the wonders of the natural world with another legendary bard and prophet, Taliesin. There are references not only to the books of Welsh poetry and myth, but to Roman and Greek poetry and myth, to Ovid, to Hesiod, to Homer.
Merlin gives his wife permission to remarry, acknowledging his inability to be with her in his madness. All he desires is a life of contemplation and learning in the woods, and Taliesin seems to be his only peer, the one from whom Merlin can learn the most. The agreement he has arranged with his sister leads to having a house built for him in the woods, along with a whole crew of servants to keep him fed and healthy while he gives his attentions to his more lofty ambitions away from society. Here Geoffrey repeats Merlin’s prophecies, though much shortened and slightly altered, but still nationalistic in character, with Arthur as the Boar of Cornwall, and Wales and Britain and its kings referred to as lions, dragons, and other creatures of metaphor. Many events that would come to be over the following centuries are painted in poetic ornament and mystique, including the death of the king, Merlin’s brother in law, as prophecies and portents without clear meaning to anyone except those who know what to look for.
Mark Walker’s translation attempts to be faithful to the feel and meaning of the original, even keeping the rhythm. As a poem it is simple in form and reads easily, designed to serve the narrative. It doesn’t distract from the lively and mythological content. It is such a subdued form that if you aren’t reading it aloud it can be easy to forget it’s a poem.
The exchanges between Merlin and Taliesin toward the end are my favorite parts. The whole thing is a charming spectacle of myth-making, but these sections borrow from the Book of Taliesin and combine Geoffrey’s skill at inventing additional fiction and fantasy from his source material. It is a metaphysical journey of scientific knowledge and natural philosophy of the twelfth century, dressed up in allusions to strange beasts and the fantastical.
Most of the later portions of the poem are pure invention by Geoffrey, with Merlin’s madness being healed by the healing streams of the woods, the appearance of another madman from Merlin’s past, and his sister joining him, Taliesin, and his friend in the woods as the new prophet. In this closing, Merlin establishes a sort of university of the woods, where he and his companions are free to study nature unbothered by others, much like the universities that were appearing in Britain at the time. It is thought that this aspect of Merlin’s story mirror’s Geoffrey’s, who was, at this point in his life, involved in the Oxford community during its growth into an academic institution.
Merlin here is no magician or wizard, but a Renaissance man of wisdom, unique insights, and knowledge of the mysteries that exist outside of human civilization. The madness he is thrown into after witnessing great losses in battle seems to carve away the parts of the psyche that would prevent a person from tapping fully into their powers as a prophet, although in his history Geoffrey has established that Merlin already possessed this ability. Perhaps the madness enhanced it, or his rough existence in the woods honed it in ways previously not possible, as he lost his connection to the fabric of society and grew more dependent on nature. Merlin undergoes a complete arc, and every stage of it makes for an engrossing character portrait and story.
