Dulness in the context of "The Dunciad"

The Dunciad (/ˈdʌnsi.æd/) is a landmark, mock-heroic, narrative poem by Alexander Pope published in three different versions at different times from 1728 to 1743. The poem celebrates a goddess, Dulness, and the progress of her chosen agents as they bring decay, imbecility, and tastelessness to the Kingdom of Great Britain.
