In the face of such various rivalries it is not strange that comedy, instead of adhering to the narrow path which Steele and others had marked out for her, should have permitted herself some vagaries of her own. Gay's example pointed the way to a fatally facile form of the comic art; and burlesque began to contribute its influence to the decline of comedy. In an age when party-government was severely straining the capabilities of its system, dramatic satire had not far to look for a source of effective seasonings. The audacity of H. Fielding, whose regular comedies (original or adapted) have secured no enduring remembrance, but whose love of parody was afterwards to suggest to him the theme of the first of the novels which have made his name immortal, accordingly ventured in two extravaganzas[246] (so we should call them in these days) upon a larger admixture of political with literary and other satire. A third attempt[247] (which never reached the stage) furnished the offended minister, Sir Robert Walpole, with the desired occasion for placing a curb upon the licence of the theatre, such as had already been advocated by a representative of its old civic adversaries. The famous act of 1737 asserted no new principle, but converted into legal power the customary authority hither exercised by the lord chamberlain (to whom it had descended from the master of the revels). The regular censorship which this act established has not appreciably affected the literary progress of the English drama, and the objections which have been raised against it seem to have addressed themselves to practice rather than to principle. The liberty of the stage is a question differing in its conditions from that of the liberty of speech in general, or even from that of the liberty of the press; and occasional lapses of official judgment weigh lightly in the balance against the obvious advantages of a system which in a free country needs only the vigilance of public opinion to prevent its abuse. The policy of the restraint which the act of 1737 put upon the number of playhouses is a different, but has long become an obsolete, question.[248]
