 Fielding 's expanded version of Tom Thumb , The Tragedy of Tragedies , first ran on 24 March 1731 . Its printed edition was " edited " and " commented " on by Fielding 's pseudonym H. Scriblerus Secundus who pretends not to be the original author , and it contains a frontispiece by Hogarth , which serves as the earliest proof of a relationship between Fielding and Hogarth . There are few major changes to the plot 's outline except that Grizzle became Tom 's rival for <unk> 's heart , and Tom is not killed by Grizzle . Instead , Tom is able to defeat Grizzle , which changes the outcome of the play . Furthermore , there is an emphasis on faulty language and Fielding emphasises the problems within poorly written tragedies .
