Both "Ode to a Nightingale" and "Ode to the West Wind" are poems written by John Keats that explore themes of nature, beauty, and mortality. While "Ode to a Nightingale" focuses on the contrast between the immortal nightingale and the mortal speaker, "Ode to the West Wind" explores the speaker's desire to harness the power of the wind for renewal and inspiration. Both odes showcase Keats's lyrical style and use of rich imagery to convey complex emotions.
