Analyze the elements of modernist poetry that enhance the setting of this poem by ezra pound: in a station of the metro the apparition of these faces in the crowd; petals on a wet, black bough.

First of all, the setting is enhanced by a stark contrast between two images that are put into the equation. The first image represents a bleak, gloomy picture of anonymous faces deep beneath the ground, in the Metro station, waiting for their train to come. The second image suddenly brings us somewhere else - into nature, with hints to the bleakness of the first scene ("wet", "black"). The setting of this short, modernist haiku poem is a big city with all modernist fascination by its crowded scenes, dynamics, and alienation. It's like the speaker froze the image, the people's actions and movements at this crowded place on a busy day. But it's not the speaker's influence; it's their very act of passively waiting for the train. By introducing the glimpse into nature, Pound made a counterpoint that provides an entirely new and fresh perspective on the city scene. Another modernist element is the use of language - everyday language, unadorned, free of all formal restraints, direct ("these") and simple. It also enhances the setting of the poem because it fits into the city context.
