July 8 - Percy Bysshe Shelley, returning from setting up The Liberal in Livorno to Lerici, is drowned when his boat sinks in a storm. His badly decomposed body, washed ashore ten days later on the beach near Viareggio, is identified by the copy of Keats' Lamia and Isabella in the jacket pocket and cremated there in the presence of his friends Lord Byron and the adventurer Edward John Trelawny who claims to have seized Shelley's heart from the flames; he gives it to Mary Shelley, who keeps it for the rest of her life. Shelley's ashes are interred at the Protestant Cemetery, Rome, where Keats was buried the year before.
* The Vision of Judgment, published anonymously as by "Quevedo Redivivus" in the first number of The Liberal, written in response to Southey's A Vision of Judgement1821; publisher John Hunt omits Byron's preface justifying the attack on Southey, indicating to Byron that the omission results from Byron's regular publisher John Murray withholding it when he forwarded the poem to Hunt.
