Still further allusions are found in early Welsh poetry. The poem "Ymddiddan Myrddin a Thaliesin", which assumes the form of a dialogue between Myrddin Wyllt (the prototype of Merlin) and the poet Taliesin, deals out praise to the brave "sons of Eliffer", saying that they did not avoid spears in the heat of battle. The apparent context is the battle of Arfderydd, where Myrddin fought as one of Gwenddoleu's warriors, went mad from terror and in this way, acquired the gift of prophecy (see also "Vita Merlini" below). For some unknown reason, however, the poem extends the number of sons to seven. A warrior called Peredur is also listed in one of the younger sections of "Y Gododdin" ("awdl" A.31), which shows him as one of the heroes to have died fighting in battle as a member of the warband of Mynyddog Mwynfawr, chieftain of the Gododdin in "the Old North". It has been argued that Peredur's appearance here may have been due to a tendency in the growth of the poem to draw personages known from such sources as the "Annales Cambriae" into the orbit of its subject matter, assuming he is the same Peredur.
