What I do know is, it is a bloody tough poem in any number of ways. The meter and the rhyme might sometimes be described as "erratic," making it very hard to read out loud sensibly. Plus, as I discovered recording, it is full of multitudes of deadly, complex plosives! Still, the internal rhythms are compelling and a real delight to read.
Looks like this will come out in three or four parts. Check in tomorrow for the next section.
