Tribal Verse Forms

Chris Murray supplies some quotes and thoughts on Mary Austin and her essay "American Rhythm". I've never heard of Austin but what I see here is fascinating. From Austin:

To understand how verse forms become fixed in tribal life we must go far enough back in the period of the Dawn Mind to be able to reject the Freudian premise of the primacy of the sex urge and the hunger urge as factors of self-realization, and boldly assert that the absorbing business of the Dawn Man was the realization of himself in relation to the Allness.

Chris finds her choices of appellation intriguing, concepts such as Dawn Mind and Allness. I agree. And the concept of tribal verse forms is also captivating. I may have to hunt this essay down.
