According to these texts Taliesin was the foster-son of Elffin ap Gwyddno, who gave him the name Taliesin, meaning "radiant brow", and who later became a king in Ceredigion, Wales. The legend states that he was then raised at his court in Aberdyfi and that at the age of 13, he visited King Maelgwn Gwynedd, Elffin's uncle, and correctly prophesied the manner and imminence of Maelgwn's death. A number of medieval poems attributed to Taliesin allude to the legend but these postdate the historical poet's "floruit" considerably.
