Oh, you would not want to read that thesis. No one ever read it but me, my advisor, and the committee. It’s just a compendium of arcane gemstone references. I don’t have a copy and I never want to see one. :)
Owning the complete Cantos has always been expensive. You could probably read the ebook version on a laptop, but never on a phone.
A periplum is a kind of map, but one based on only what mariners could see of a coast as they passed by. I think the term is Phoenician in origin. No one seems to know where Pound learned it and I’m not sure anyone else has ever used it.
Hang in there. Pound, like Joyce, is a lifetime project.
