After 1738, Pope wrote little. He toyed with the idea of composing a patriotic epic in blank verse called Brutus, but only the opening lines survive. His major work in these years was revising and expanding his masterpiece The Dunciad. Book Four appeared in 1742, and a complete revision of the whole poem in the following year. In this version, Pope replaced the "hero", Lewis Theobald, with the poet laureate Colley Cibber as "king of dunces". But the real focus of the revised poem is Walpole and all his works. By now Pope's health, which had never been good, was failing. When told by his physician, on the morning of his death, that he was better, Pope replied: "Here am I, dying of a hundred good symptoms." He died in his villa surrounded by friends on 30 May 1744, about eleven o'clock at night. On the previous day, 29 May 1744, Pope had called for a priest and received the Last Rites of the Roman Catholic Church. He was buried in the nave of St Mary's Church, Twickenham.
