Speaking of Renaissance poetics... I am back deep into ancient/medieval number symbolism & gematria again. Might help me get out of my creative slump. I am reminded, reading things like Medieval Numerology (ed. Surles; Garland Press, 1993), of some things I was up to in Forth of July & earlier work. Influence of books by the likes of Alastair Fowler, John Michell.
Mathematics can actually advance composition. The symbolic symmetries of numbers. This is a huge dimension of pre-modern poetics, which we have simply buried out of sight. One of the most exciting discoveries of writing poetry, for me. It's in Melville (see Viola Sachs' book, Game of Creation). It's in my work! I'm not sure where else. (I'm sure it's in Crane.)
Forth of July is possibly the beginning of a kind of medieval push-back or resurgence of some kind. Maybe someday it will be understood as such. A labyrinthine-baroque cathedral, a counter-modern-American architectural wonder... meant to be seen as distinct from what anyone else is doing these days...
essentially an Acmeist project (Mandelstam : poet as builder). In fact I originally got into Alastair Fowler et al. by way of a study of ring-structures in Mandelstam's odes.
