a source for every detail of the narrative: the narrator whose text we have may have freely indulged in original creativity. A parallel case with traditional stories in Ireland is found in the examples given in J.E. Caerwyn-Williams, Y Storïwr Gwyddeleg a'i Chwedlau (University of Wales Press), where Caerwyn-Williams freely admits that the form of the story given by the storyteller depends on the audience to which it is delivered. It is not necessary therefore always to find literary sources for such tales in their Middle Welsh form: in any case, most written sources will have perished, and there is no way that we can tell if the surviving sources are in any way representative of the whole of what might have been extant.
