layamon

Layamon or Laghamon – spelled Laȝamon or Laȝamonn in his time, occasionally written Lawman – was an English poet of the late 12th/early 13th century and author of the Brut, a notable work that was the first to present the legends of Arthur and the Knights of the Round Table in English poetry (the first Arthurian poems were by Frenchman Chrétien de Troyes).
