John Latta at the Hotel on Abstract Expressionists, Zukofsky's object-at-rest. I just finished reading N. Cusanus's Compendium, so offer his simple four-foldity :

point / line / plane / solid object
letter / syllable / word / sentence

(& more obscurely : Capability / Equality / Unity / Similarity - which I suppose could be figured as:

Power = point/letter
Equality = line/syllable
Unity = surface/word
Representation = object/sentence

Cusanus writes : any shape - a line, a circle, a sphere - is an image formed of equality.
