Merlyn is a character in
T. H. White’s novels
The Sword in the Stone and
The Once and Future King. In White’s version of the life of King Arthur, Merlyn was born in the future and lives his life backward toward the beginning of time. In the 1930s (White’s own time), Merlyn says he was a schoolteacher, thus telegraphing White’s own sense of identification with the character. By the time he becomes the future King Arthur’s teacher, Merlyn is an old man full of wisdom and prophecy—mostly because of his backwards life, which means that his past is everybody else’s future.
