Which English Romantic poet composed the fragment 'Hyperion'?

John Keats composed the fragment Hyperion. Keats began this ambitious epic poem in late 1818, during a period of intense personal and literary pressure. It retells the mythic overthrow of the Titans by the younger Olympian gods, focusing on the fallen Titans' grief and uncertainty as a new cosmic order takes shape.

The poem is written in elevated blank verse strongly influenced by John Milton, especially Paradise Lost. Keats eventually abandoned it, reportedly feeling that its “Miltonic inversions” made the style too derivative. The surviving poem breaks off in the middle of its third book, with nearly 900 lines completed.

Hyperion appeared posthumously in the 1820 volume Lamia, Isabella, The Eve of St. Agnes, and Other Poems. Keats later revisited the subject in The Fall of Hyperion: A Dream, an unfinished poem that shifts the myth into a more personal quest involving poetic vocation and truth. William Blake, Lord Byron, and Percy Bysshe Shelley were also major English Romantic poets, but none composed this particular fragment.
