Read the excerpt from "rhapsody on a windy night." twelve o'clock. along the reaches of the street held in a lunar synthesis, whispering lunar incantations dissolve the floors of memory and all its clear relations, its divisions and precisions, every street-lamp that i pass beats like a fatalistic drum, and through the spaces of the dark midnight shakes the memory as a madman shakes a dead geranium. what does this excerpt from the poem describe?
