The Dunciad is a landmark literary satire by Alexander Pope published in three different versions at different times. The first version—the "three book" Dunciad—was published in 1728 anonymously. The second version, the Dunciad Variorum was published anonymously in 1729. The New Dunciad, in a new fourth book conceived as a sequel to the previous three, appeared in 1742, and The Dunciad in Four Books a revised version of the original three books and a slightly revised version of the fourth book with revised commentary was published in 1743 with a new character, Bays, replacing Tibbald as the 'hero'. The poem celebrates the goddess Dulness and the progress of her chosen agents as they bring decay, imbecility, and tastelessness to the Kingdom of Great Britain.
