Merlin () is a mythical figure prominently featured in the legend of King Arthur and best known as a prophet and a magician, along with several other main roles. The familiar depiction of Merlin, based on an amalgamation of historical and legendary figures, was introduced by the 12th-century Catholic cleric Geoffrey of Monmouth and then built on by the French poet Robert de Boron and prose successors in the 13th century. Geoffrey's account presented Merlin as a prophet and royal advisor to Arthur's father, Uther Pendragon.
