Percy Bysshe Shelley 
Adonais 

"Adonais" represents the height of artistic achievement for nineteenth-century Romantic poetry. Percy Bysshe Shelley’s book-length elegy in the pastoral style mourns the loss of fellow poet John Keats in 495 remarkably accomplished lines. Shelley himself regarded "Adonais" as the best of his work, and the poem is a must-read for fans of the Romantic movement, or for anyone who has struggled with loss.
