Letters of Jonathan Oldstyle, Gent-Washington Irving

This novel is sometimes thought of as [Fielding's] first because he almost certainly began composing it before he wrote Shamela and Joseph Andrews. It is a satire of Walpole that draws a parallel between Walpole and Jonathan Wild, the infamous gang leader and highwayman. He implicitly compares the Whig party in Parliament with a gang of thieves being run by Walpole, whose constant desire to be a "Great Man" (a common epithet for Walpole) should culminate only in the antithesis of greatness: being hanged.
