Question: What year did the author of Julian and Maddalo die?

full_context: Document 1: Prometheus Unbound (Shelley): Prometheus Unbound is a four-act lyrical drama by Percy Bysshe Shelley, first published in 1820. It is concerned with the torments of the Greek mythological figure Prometheus, who defies the gods and gives fire to humanity, for which he is subjected to eternal punishment and suffering at the hands of Zeus. It is inspired by the classical "Prometheia", a trilogy of plays attributed to Aeschylus. Shelley's play concerns Prometheus' release from captivity, but unlike Aeschylus' version, there is no reconciliation between Prometheus and Jupiter (Zeus). Instead, Jupiter is abandoned by his supportive elements and falls from power, which allows Prometheus to be released.
Document 2: Percy Bysshe Shelley: Percy Bysshe Shelley ( ; 4 August 17928 July 1822) was one of the major English Romantic poets, who is regarded by some as among the finest lyric and philosophical poets in the English language, and one of the most influential. A radical in his poetry as well as in his political and social views, Shelley did not see fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death. Shelley was a key member of a close circle of visionary poets and writers that included Lord Byron, John Keats, Leigh Hunt, Thomas Love Peacock and his own second wife, Mary Shelley, the author of "Frankenstein".
Document 3: Julian and Maddalo: Julian and Maddalo: A Conversation (1818–19) is a poem in 617 lines of enjambed heroic couplets by Percy Bysshe Shelley published posthumously in 1824.
Document 4: Castle Goring: Castle Goring was designed by John Rebecca for Sir Bysshe Shelley, 1st Baronet. It was intended that his grandson, the renowned poet Percy Bysshe Shelley, would live at Castle Goring; however, he drowned in Italy aged just 29, so he never took possession of the house.
Document 5: A Philosophical View of Reform: A Philosophical View of Reform is a major prose work by Percy Bysshe Shelley written in 1819-20 and first published in 1920 by Oxford University Press. The political essay is Shelley's longest prose work.
Document 6: Adonais: Shelley regarded Adonais as the ``least imperfect ''of his works. In a 5 June 1821 letter to John and Maria Gisborne, Shelley wrote about the work:`` It is a highly wrought piece of art, perhaps better in point of composition than anything I have written.''
Document 7: Mary Shelley: Mary Shelley was born Mary Wollstonecraft Godwin in Somers Town, London, in 1797. She was the second child of the feminist philosopher, educator, and writer Mary Wollstonecraft, and the first child of the philosopher, novelist, and journalist William Godwin. Wollstonecraft died of puerperal fever shortly after Mary was born. Godwin was left to bring up Mary, along with her older half-sister, Fanny Imlay, Wollstonecraft's child by the American speculator Gilbert Imlay. A year after Wollstonecraft's death, Godwin published his "Memoirs of the Author of A Vindication of the Rights of Woman" (1798), which he intended as a sincere and compassionate tribute. However, because the "Memoirs" revealed Wollstonecraft's affairs and her illegitimate child, they were seen as shocking. Mary Godwin read these memoirs and her mother's books, and was brought up to cherish her mother's memory.
Document 8: Claire Clairmont: Clara Mary Jane Clairmont (27 April 1798 – 19 March 1879), or Claire Clairmont as she was commonly known, was the stepsister of writer Mary Shelley and the mother of Lord Byron's daughter Allegra. She is thought to be the subject of a poem by Percy Bysshe Shelley.
Document 9: Ode to the West Wind: "Ode to the West Wind" is an ode, written by Percy Bysshe Shelley in 1819 near Florence, Italy. It was originally published in 1820 by Charles in London as part of the collection "Prometheus Unbound, A Lyrical Drama in Four Acts, With Other Poems". Perhaps more than anything else, Shelley wanted his message of reform and revolution spread, and the wind becomes the trope for spreading the word of change through the poet-prophet figure. Some also believe that the poem was written in response to the loss of his son, William (born to Mary Shelley) in 1819. The ensuing pain influenced Shelley. The poem allegorises the role of the poet as the voice of change and revolution. At the time of composing this poem, Shelley without doubt had the Peterloo Massacre of August 1819 in mind. His other poems written at the same time—"The Masque of Anarchy", "Prometheus Unbound", and "England in 1819"—take up these same themes of political change, revolution, and role of the poet.

Document 15: Age of Enlightenment: The influence of science also began appearing more commonly in poetry and literature during the Enlightenment. Some poetry became infused with scientific metaphor and imagery, while other poems were written directly about scientific topics. Sir Richard Blackmore committed the Newtonian system to verse in Creation, a Philosophical Poem in Seven Books (1712). After Newton's death in 1727, poems were composed in his honour for decades. James Thomson (1700–1748) penned his "Poem to the Memory of Newton," which mourned the loss of Newton, but also praised his science and legacy.
