[W, prophecy of Britain].
A 10th-century Welsh poem of 200 lines calling upon all Celtic peoples, as well as the Scandinavians of Dublin, to drive the Saxons from the Isle of Britain. Described by Nora Chadwick (1969) as ‘the greatest of all Welsh patriotic poems’, it also contains the first reference to Myrddin (Merlin).
