another is the fact that Byron spent many years in self-imposed exile in Italy and Greece, which made it necessary for him to write to keep in touch with his friends in England; and finally, the sensational success of Childe Harold's Pilgrimage when Byron was only 23 turned him into a national and then international celebrity, making his letters valuable relics to be collected rather than thrown away. Correspondents Byron's correspondents can be divided up into successive groups. As a boy he wrote to his mother, his half-sister Augusta, and the family lawyer John Hanson. At Southwell there were John Pigot and his sister Elizabeth. Byron's friends at college included Scrope Davies, John Cam Hobhouse and Francis Hodgson. With the publication of Childe Harold he became known to a new circle, the poets Robert Charles Dallas, Thomas Moore and Samuel Rogers, along with his banker Douglas Kinnaird and his publisher John Murray. Then there were the women who fell in love with him: Lady Caroline Lamb, Lady Frances Webster, Lady Oxford, and his future wife Annabella Milbancke; also his confidante Lady Melbourne. A new group of friends in Switzerland included the poet Percy Bysshe Shelley, Shelley's wife Mary and sister-in-law Claire Clairmont. Members of the Shelley circle with whom Byron corresponded included Thomas Medwin, Edward Williams and his common-law wife Jane, Edward John Trelawny, and the poet Leigh Hunt. In Venice there were Byron's lover Teresa Guiccioli, her brother Gamba and husband Count Guiccioli, the British consul Richard Belgrave Hoppner, and Alexander Scott. Finally, Byron's Greek adventure brought him into contact with a new circle: the rebel leader Prince Mavrokordatos, the banker Samuel Barff, and members of the London Philhellenic Committee, including Colonel Leicester Stanhope. Editions In 1830, 6 years after his death, about 560 of Byron's letters were published by his friend Thomas Moore under the title Letters and Journals of Lord Byron: With Notices of his Life. The next edition of the letters and journals appeared in six volumes in 1898-1901, edited by R. E. Prothero as part of a 13-volume Works. Prothero included nearly 1200 letters, conscientiously edited, though like Moore he excised all passages likely to offend 19th-century sensibilities. A collection of about 350 unpublished letters was bequeathed by John Hobhouse's daughter Lady Dorchester to John Murray, who published them as Lord Byron’s Correspondence in 1922, in two volumes, though yet again in a bowdlerized form.
