It is a "musical" allusion to the apocryphal story of Susanna, a beautiful young wife, bathing, spied upon and desired by the elders. The Peter Quince of the title is the character of one of the "mechanicals" in Shakespeare's "A Midsummer Night's Dream". Stevens' poem titles are not necessarily a reliable indicator of the meaning of his poems, but Milton Bates suggests that it serves as ironic stage direction, the image of "Shakespear's rude mechanical pressing the delicate keyboard with his thick fingers" expressing the poet's self-deprecation and betraying Stevens's discomfort with the role of "serious poet" in those early years.
