Taliesin

Taliesin also sang in praise of Cynan Garwyn king of Powys Wales. It is elaborated upon in modern English poetry such as Tennyson's Idylls of the King and Charles Williams's Taliessin Through Logres. Once freed Taliesin provoked Elphin to wager that he also had a faster horse than the king.

6th century; (/ˌtæliˈɛsɨn/; Welsh pronunciation: [talˈjɛsɪn]) was an early Brythonic poet of Sub-Roman Britain whose work has possibly survived in a Middle Welsh manuscript the Book of Taliesin. The bulk of this work praises King Urien of Rheged and his son Owain mab Urien although several of the poems indicate that he also served as the court bard to King Brochfael Ysgithrog of Powys and his successor Cynan Garwyn either before or during his time at Urien's court. Taliesin was highly regarded in the mid-twelfth century as the supposed author of a great number of romantic legends.
