The opening pages of this book contain, so one may hope, an adequate answer to the objections of those who may have been led by its title to expect a more detailed treatment of poetic origins and a closer study of such questions as the early forms of rhythm, the beginnings of national literatures, and the actual history of lyric, epic, and drama. Not these problems have been undertaken, interesting and important as they are, but rather the rise of poetry as a social institution; whether or not a definite account of this process has been obtained must be left for the reader to judge.
