... His name Taliessin has been interpreted as "Splendid Forehead," and he has been the subject of endless mysticism.  So thick are the legends about him that he (the real Taliessin) is hidden quite out of sight.  His very existence as a real personality has been questioned.  But that is hardly justified by known facts.  There did live a Taliessin, and for some unknown reason the pagan bards began to idealise him almost out of the world of realities.  The name occurs in a tract, the date of which has been fixed at 690.  In a "cistfaen" at Llanfihangel Geneu'r Glyn, in Cardiganshire, there is evidence to show that the genuine Taliessin was buried there, and not far off is a village named after him...
