progression of beats, and catches itself up on the same point of rhyme for line after line. The key pattern on the lip of a Greek vase may be beautiful, but it is less beautiful, less satisfying, and less conclusive a test of artistic ability than the composition of satyrs and of mænads struggling about the centre. Therefore I maintain, and will continue to do so, that the mere craftsman-ability to write in regular lines and metres no more makes a man a poet than the ability to stencil wall-papers makes him a painter. Rather is it more important to observe that almost any prose work of imaginative literature, if examined closely, will be found to contain a plentiful sprinkling of excellent verses; while many poems which the world hails as master-pieces, contain whole pages of prose. The fact is, that prose and poetry are to literature as composition and colour are to painting, or as light and shadow to the day, or male and female to mankind. There are no absolutely perfect poets and no absolutely perfect prose-writers. Each partakes of some of the characteristics of the other. The difference between poetry and prose is, therefore, a difference between a general roundness and a general squareness of outline. A great French critic, recently dead, who devoted perhaps the major part of his life to the study of the æsthetics of the French tongue, declared that Flaubert and Chateaubriand wrote only poetry. If there are those who cannot see that in the only true and lasting sense of the word poetry, this remark was perfectly just, then all I have written above will be in vain. IV Along with the prevailing preoccupation with technique which so marks the early twentieth century, there has gone also a great change in the subject-matter of art. Having tried to explain the aesthetic form-basis of poetry, I shall now attempt to explain my personal way of viewing its content. It is a significant fact that every change in technical procedure in the arts is accompanied by, and grows out of, a change in subject-matter. To take only one out of innumerable examples, the new subject-matter of Wagner's music-dramas, of an immeasurably higher order than the usual libretto, created a new form of music, based on motifs, not melodies. Other examples can easily be discovered. The reason for this is not difficult to find. No sincere artist cares to handle subject-matter that has already been handled and exhausted. It is not a question of a desire to avoid plagiarism, or of self-conscious searching for novelty, but of a perfectly
