The protagonist, Des Esseintes, is a disillusioned aristocrat who retreats from society to live in isolation, surrounding himself with artificial beauty and sensory experiences.

Pablo Picasso's career is traditionally divided into several well-defined phases, including the Blue Period (characterized by melancholic themes), the Rose Period (featuring warmer tones), and various stages of Cubism, such as Analytic and Synthetic.

Paul Fussell, a prominent literary critic, argued that irony was a central theme in English poetry written during World War I.

Imagism, a movement in early 20th-century Anglo-American poetry, favored precision of imagery and clear, sharp language. Led by figures like Ezra Pound, the movement sought to strip away unnecessary ornamentation and abstract sentimentality, focusing instead on the direct treatment of the 'thing' whether subjective or objective. The goal was to present an image that was clear, concise, and evocative, rather than relying on traditional metrical structures or flowery rhetoric.

Wallace Stevens’s 'Sunday Morning' explores the tension between the immediate, sensory experience of nature and the abstract, inherited structures of Christian belief. By contrasting the beauty of the physical world with the traditional Christian narrative of salvation and the afterlife, Stevens questions the necessity of religious dogma in a modern world. The poem advocates for finding meaning within the temporal, earthly life rather than relying on spiritual promises of transcendence.
