Taliesin was a poet of the late 6th century who sang the praises of Urien, king of Rheged in what is now northern England and southern Scotland. A small group of poems in the 14th-century Book of Taliesin are thought to be genuinely his.
Later legend turned him into a magical figure, the boy Gwion Bach who was reborn from the witch Ceridwen. For medieval poets he was the model of the inspired bard.
Bardd o ddiwedd y chweched ganrif oedd Taliesin, a ganodd glod Urien, brenin Rheged yn yr Hen Ogledd. Credir bod rhai o’r cerddi yn Llyfr Taliesin o’r bedwaredd ganrif ar ddeg yn waith dilys iddo.
Trodd chwedloniaeth ddiweddarach ef yn ffigwr hudol, y bachgen Gwion Bach a aileni o groth y wrach Ceridwen. I feirdd yr Oesoedd Canol, ef oedd delfryd y bardd awenus.
