In a note at the end of my last book 'The Wild Swans at Coole' (Cuala Press.) I explained why I preferred this kind of drama, and where I had found my models, and where and how my first play after this kind was performed, and when and how I would have it performed in the future. I can but refer the reader to the note or to the long introduction to 'Certain Noble Plays of Japan' (Cuala Press.)
