More detailed traditions of Taliesin's biography arose from about the 11th century, and in "Historia Taliesin" ("The Tale of Taliesin", surviving from the 16th century). In the mid-16th-century, Elis Gruffydd recorded a legendary account of Taliesin that resembles the story of the boyhood of the Irish hero Fionn mac Cumhail and the salmon of wisdom in some respects. The tale was also recorded in a slightly different version by John Jones of Gellilyfdy (c. 1607). This story agrees in many respects with fragmentary accounts in the "Book of Taliesin".
