 To Albert Rivero , ten of the plays " mark significant moments in [ Fielding 's ] theatrical life " : Love in Several Masques , The Temple Beau , The Author 's Farce , Tom Thumb , The Tragedy of Tragedies , Rape upon Rape , The Grub Street Opera , The Modern Husband , Pasquin , and The Historical Register . Similarly , Potter organised the plays by a general theme of developing libertine characters and believed that " Fielding 's most successful group of plays followed Love in Several Masques both chronologically and thematically . Comedies and burlesques such as The Author 's Farce , The Tragedy of Tragedies , The Old Debauchees , and Pasquin made Fielding the most popular playwright of the 1730s , and all of these plays contain characters , situations , and dialogues that invoke libertine philosophy in some way , thought they vary in the explicitness of the depiction . " In his biography of Fielding , Pagliaro declares that " Between 1727 and 1737 , by which time he was only 30 years old , Fielding became England 's most successful living playwright . "
