"Hyperion" is an uncompleted epic poem by 19th-century English Romantic poet John Keats. It is based on the Titanomachia, and tells of the despair of the Titans after their fall to the Olympians. Keats wrote the poem from late 1818 until the spring of 1819, when he gave it up as having "too many Miltonic inversions." He was also nursing his brother Tom, who died in January of 1819 of tuberculosis.
The themes and ideas were picked up again in Keats's The Fall of Hyperion: A Dream, when he attempted to recast the epic by framing it with a personal quest to find truth and understanding.
