“ What is the explanation of this revival, and this sudden great vogue of alliterative poetry? It cannot have been a new invention, or a reconstruction; it would not in that case have copied, as it sometimes does, the rhythm of the old English verse in a way which is unlike the ordinary rhythms of the fourteenth century. The only reasonable explanation is that somewhere in England there was a tradition of alliterative verse, keeping in the main to the old rules of rhythm as it kept something of the old vocabulary, and escaping the disease which affected the old verse elsewhere. ”
