Sylvia Plath's poem "Ariel" expresses the poet's desire to be liberated. It can be read literally as describing riding a horse named Ariel, or metaphorically as experiencing unity with the horse. On a biographical level, Ariel was Plath's favorite horse that she rode weekly, and the poem depicts willingly accepting the ride into nothingness, reflecting Plath's own desire for self-destruction. The poem uses vivid imagery and references to portray the horse's power and strength, as well as the speaker's growing sense of empowerment, as she sheds constraints on her life. Formal elements like rhyme and structure build pace and signal shifts in the increasingly intense themes.
