“who chained themselves to subways for the endless ride from Battery
to holy Bronx on benzedrine until the noise of wheels and children
brought them down shuddering mouth-wracked and battered bleak of brain and drained of brilliance in the drear light of Zoo,”
—Allen Ginsberg (b. 1926)
“The wide wonder of Broadway is disconsolate in the daytime; but gaudily glorious at night, with a milling crowd filling sidewalk and roadway, silent, going up, going down, between upstanding banks of brilliant lights, each building braided and embossed with glowing, many-coloured bulbs of man-rayed luminance. A glowing valley of the shadow of life. The strolling crowd went slowly by through the kinematically divine thoroughfare of New York.”
—Sean O’Casey (1884–1964)
