/* ''Mason & Dixon'' */
Pynchon's fifth novel, ''[[Mason & Dixon]]'', was published in 1997. Pynchon began writing it as early as January 1975.<ref>Gussow</ref> The meticulously-researched novel is a sprawling saga recounting the lives and careers of the English astronomer, [[Charles Mason]], and his partner, the surveyor [[Jeremiah Dixon]], and the birth of the [[American Revolution|American Republic]]. While it received some negative reviews, the great majority of commentators acknowledged it as a welcome return to form, and some, including Bloom, have called it Pynchon's greatest work to date.
After the publication of ''Mason & Dixon'', a user by the online name of "[[Martin Scribler]] " posted a handful of messages on the Pynchon-L mailing list denouncing many members of that group as "dunces all" for discussing their own neuroses over actual literary discussion. Due to the high quality of Martin Scriblers' posts, their message, and the historical significance of his Pynchonesque name(alluding to an 18th-century satire of pretentious erudition), many have speculated that Pynchon himself wrote these posts.
