The power of eleven

One of my recent poetry acquisition treasures is Measure for Measure:  An Anthology of Poetic Meters, edited by Annie Finch and Alexandra Oliver (Everyman's Lbrary, 2015).  From a DC poet and friend, Paul Hopper, a few weeks ago I received comments about one of the sections of this collection  -- a section containing stanzas in hendecasyllabics, that is, in 11-syllable lines  Hopper has sent a sample quatrain of hendecasyllabics that points to "Into Melody" by Lewis Turco.  A bit of mathematical terminology is found in the opening lines of Peter Kline's "Hendecasyllabics for Robert Frost" -- and I offer these samples below.

Hopper's quatrain:

Someone should build a large dodecahedron,
with a poem in hendecasyllabics
on each pentagonal face except the base.
I'd start with this poem by Lewis Turco. 

Geometry and autism

We do not easily describe what goes on inside our own heads and have still greater difficulty seeing into the minds of others.  Pennsylvania poet Barbara Crooker uses images from geometry to help us to see into autism.
