"The predicate of bright origin"
— A phrase of Wallace Stevens from "An Ordinary Evening in New Haven" (1950)
Perhaps the predicate Stevens means is "bright."
If so, an apt illustration can be found on the cover of
the 1943 first edition of Hesse's Glasperlenspiel—
See also Stevens's use of the phrase "heaven-haven" in "Notes" (1942),
the original plan of New Haven, and related scholia in this journal.
… Todo lo sé por el lucero puro
que brilla en la diadema de la Muerte.
– Rubén Darío
An academic work from 2003 discusses Stevens's "Notes" as
"a perfect geometric whole."
Note that "perfect" means "complete, finished, done."
