The Shelleys took up residence in the village of Marlow, Buckinghamshire where a friend of Percy's, Thomas Love Peacock, lived. Shelley took part in the literary circle that surrounded Leigh Hunt, and during this period, he met John Keats. Shelley's major production during this time was Laon and Cythna, a long, narrative poem in which he attacked religion and featured a pair of incestuous lovers. It was hastily withdrawn after only a few copies were published. It was later edited and reissued as The Revolt of Islam in 1818. Shelley also wrote two revolutionary political tracts under the nom de plume of "The Hermit of Marlowe."
Travels in the Italian peninsula
Early in 1818, the Shelleys and Claire left England in order to take Claire's daughter, Allegra, to her father Byron, who had taken up residence in Venice. Contact with the older and more established poet encouraged Shelley to write once again. During the latter part of the year, he wrote Julian and Maddalo, a lightly disguised rendering of his boat trips and conversations with Byron in Venice, finishing with a visit to a madhouse. This poem marked the appearance of Shelley's "urbane style". He then began the long verse drama Prometheus Unbound, a re-writing of the lost play by the ancient Greek poet Aeschylus, which features talking mountains and a petulant spirit who overthrows Jupiter. Tragedy struck in 1818 and 1819, when his son Will died of fever in Rome, and his infant daughter Clara Everina died during yet another household move.
A daughter, Elena Adelaide Shelley, was born December 27, 1818 in Naples, Italy and registered there as the daughter of Shelley and a woman named Marina Padurin. However, the identity of the mother is an unsolved mystery. Some scholars speculate that her true mother was actually Claire Clairmont or Elise Foggi, a nursemaid for the Shelley family. Other scholars postulate that she was a foundling Shelley adopted in hopes of distracting Mary after the deaths of William and Clara.[4] Shelley referred to Elena in letters as his "Neapolitan ward". However, Elena was placed with foster parents a few days after her birth and the Shelley family moved on to yet another Italian city, leaving her behind. Elena died 17 months later, on June 10, 1820.
The Shelleys moved around various Italian cities during these years. Shelley completed Prometheus Unbound in Rome, and he spent the summer of 1819 writing a tragedy, The Cenci, in Livorno. In this year, prompted among other causes by the Peterloo massacre, he wrote his best-known political poems: The Masque of Anarchy and Men of England. These were most likely his most-remembered works during the 19th century. Around this time period, he wrote the essay The Philosophical View of Reform, which was his most thorough exposition of his political views to that date.
In 1820, hearing of John Keats' illness from a friend, Shelley wrote him a letter inviting him to join him at his residence at Pisa. Keats replied with hopes of seeing him, but instead, arrangements were made for Keats to travel to Rome with the artist Joseph Severn. ()
