This
category is for articles relating to Merlin, a mythological figure prominently featured in the legend of
King Arthur and best known as an
enchanter or wizard. His usual depiction, based on an amalgamation of historical and legendary figures, was introduced by the 12th-century British author
Geoffrey of Monmouth. Geoffrey primarily combined existing stories of
Myrddin Wyllt, a
North Brythonic prophet and madman with no connection to Arthur, with tales of the
Romano-British war leader
Ambrosius Aurelianus to form the composite figure he called Merlinus Ambrosius (
Welsh: Myrddin Emrys,
Breton: Merzhin Ambroaz).
