“Decade after decade, artists came to paint the light of Provincetown, and comparisons were made to the lagoons of Venice and the marshes of Holland, but then the summer ended and most of the painters left, and the long dingy undergarment of the gray New England winter, gray as the spirit of my mood, came down to visit.”

“Irrational streams of blood are staining earth;
Empedocles has thrown all things about;

We that look on but laugh in tragic joy.”
