Lewis Theobald abandoned the law for a career as a translator, poet, and editor; he was brave enough (or foolhardy enough) to find fault with both John Dennis and Alexander Pope. In Shakespeare Restored (1726), Theobald pointed out editorial errors and oversights in Pope's edition of Shakespeare, for which he was awarded the chief place in the the original Dunciad. His work on Shakespeare was regarded highly enough that the Prince Frederick recommended Theobald to succeed Eusden as Poet Laureate.
