Myrddin Wyllt (Welsh: [ˈmərðɪn ˈwɨɬt]—"Myrddin the Wild") is a figure in medieval Welsh legend. A prophet and a madman, he was introduced into Arthurian legend by Geoffrey of Monmouth as Merlin the wizard, associated with the town of Carmarthen in South Wales. In Middle Welsh poetry he is accounted a chief bard, the speaker of several poems in The Black Book of Carmarthen and The Red Book of Hergest. He is called Wyllt—"the Wild"—by Elis Gruffydd, and elsewhere Myrddin Emrys ("Ambrosius"), Merlinus Caledonensis ("of Caledonia") or Merlin Sylvestris ("of the woods").
