Place names and monuments close to Bedd Taliesin, the bronze age cairn in the Cletwr Valley, could throw a little light on why it bears the name of a popular Welsh folk hero. It’s impossible to tell whether this was originally the grave of the historic Taliesin, chief bard to Urien Rheged, although there’s no reason why (no matter how unlikely) he couldn’t have been buried there at a later date. Such ancient cairns were used time and again throughout long periods of time. But whether or not the historic Taliesin is buried in this ancient monument is of less importance than its association with the legendary figure that the famous Cynfardd became: the accidental child of Ceridwen, the reborn Gwion Bach and bard to the hapless Elffin.
The cairn itself is situated in a place called Pen y Sarn Ddu, or ‘End of the Black Road’, a name still retained by the old farm next to the cairn. It would be easy to assume that this name refers to the old ‘Roman’ road, or Sarn Helen, that runs past the farm following the coastal highland from Machynlleth to Aberystwyth. But that ancient highway doesn’t end at Bedd Taliesin, so why call it the ‘End of the Black Road’?
It’s more likely that the farm’s name refers to the old track that runs at right angles to the Roman road, following the Cletwr Valley east towards Moel-y-Llyn. So if this is the ‘End of the Black Road’, where is its beginning? The present track runs along the south side of the valley through Cae’r Arglwyddes Farm and due east up the slope of Moel-y-Llyn through the pass into the Einion Valley. If the Black Road originally followed a similar path, we can see it takes a straight line from Bedd Taliesin, through Cae’r Arglwyddes Farm to the pass into the Einion Valley. If we extend that straight line down the other side of Moel-y-Llyn we come to a small farmstead called Bronwion, or ‘Gwion’s Hill’. Is this where the Black Road begins?
