demise lamenting Oh weep for Adonais though our tears Thaw not the frost which binds so dear a head This mournful cry reflects the tragic similarity in the premature deaths of both Adonais and Keats Unjust Treatment and Criticism Adonais and Keats both faced ridicule and misunderstanding during their lives Adonais's story involves themes of jealousy and tragedy Keats too experienced harsh criticism and mockery for his poetry during his lifetime Immortality through Art and Spirit Adonais's spirit lives on through mythology Keats's poetry and spirit endure despite his physical death This ensures his immortality Adonais's beauty and myth endure through time Similarly Keats's poetry and spirit are immortalized through Shelley's elegy Shelley articulates this idea saying Yet reigns o'er earth the third among the sons of light This symbolizes Keats's enduring presence and influence despite his physical absence Through these parallels Shelley honours Keats's life and art He aligns him with the mythological figure Adonais This is how Shelley emphasizes both figures's tragic beauty and immortal nature
