The Three-book Dunciad A and The Dunciad Variorum
Pope first published The Dunciad in 1728 in three books, with Lewis Theobald as its "hero." The poem was not signed, and he used only initials in the text to refer to the various Dunces in the kingdom of Dulness. However, "Keys" immediately came out to identify the figures mentioned in the text, and an Irish pirate edition was printed that filled in the names (sometimes inaccurately). Additionally, the men attacked by Pope also wrote angry denunciations of the poem, attacking Pope's poetry and person. Pope endured attacks from, among others, George Duckett, Thomas Burnet, and Richard Blackmore. All of these, however, were less vicious than the attack launched by Edmund Curll, a notoriously unscrupulous publisher, who produced his own pirate copy of the Dunciad with astounding swiftness, and also published 'The Popiad' and a number of pamphlets attacking Pope.
In 1729, Pope published an acknowledged edition of the poem, and the Dunciad Variorum appeared in 1732. The Variorum was substantially the same text as the 1729 edition, but it now had a lengthy prolegomenon. The prefatory material has Pope speaking in his own defense, although under a variety of other names; for example, "A Letter to the Publisher Occasioned by the Present Edition of the Dunciad" is signed by William Cleland (d. 1741), one of Pope's friends and father of John Cleland, but it was probably written by Pope himself.
In these prefatory materials, Pope points out that the Keys were often wrong about the allusions, and he explains his reluctance at spelling out the names. He says that he wishes to avoid elevating the targets of the satire by mentioning their names (which, of course, did happen, as a number of persons are only remembered for their appearances in the poem), but he similarly did not want innocents to be mistaken for the targets. Pope also apologizes for using parody of the Classics (for his poem imitates both Homer and Virgil) by pointing out that the ancients also used parody to belittle unworthy poets. Pope's preface is followed by advertisements from the bookseller, a section called "Testimonies of Authors Concerning Our Poet and his Works" by "Martinus Scriblerus," and a further section named "Martinus Scriblerus, of the Poem."
Martinus Scriblerus was a corporate identity employed by Pope and the other members of the Scriblerians. Therefore, these two portions of the preface could have been written by any of its members, but they, like the other prefatory materials, were most likely written by Pope himself. The various Dunces had written responses to Pope after the first publication of The Dunciad, and they had not only written against Pope, but had explained why Pope had attacked other writers. In the "Testimonies" section, Martinus Scriblerus culls all the comments the Dunces made about each other in their replies and sets them side by side, so that each is condemned by another. He also culls their contradictory characterizations of Pope, so that they seem to all damn and praise the same qualities over and over again.
The "Testimonies" also includes commendations from Pope's friends. The words of Edward Young, James Thomson and Jonathan Swift are brought together to praise Pope specifically for being temperate and timely in his charges. The conclusion asks the reader "to chuse whether thou wilt incline to the Testimonies of Authors avowed" (like Pope's friends) "or of Authors concealed" (like many of the Dunces)--in short, "of those who knew him, or of those who knew him not."
