David and others,
 
Oops!  Here's the correction to the first paragraphs of my last message
on form:
 
You might want to take a look at my 1983 dissertation, "Directio
Voluntatis:  Ezra Pound's Development of the Long Poem, 1904-1925" (UBC)
 
for some ideas on themes and structures.
 
1.  Pound had tried to write a number of  "long poems" from around age
16 (even before "Redondillas" - 1911).  Imagisme was the conscious
practice of one necessary component for his epic.
 
Happy summer, all!
