To better understand the following poem, it may be helpful to read (or re-read) my blogs that immediately precede this one.
From the poet Wallace Stevens:
Theory
I am what is around me.
Women understand this.
One is not duchess
A hundred yards from a carriage.
These, then are portraits:
A black vestibule;
A high bed sheltered by curtains.
These are merely instances.
