Yet tragedy was by no means neglected in literature or on the stage. Several hundred tragedies were published during the century and many of them went through several editions. Three or four were brought out every year in the theatres, and many of these maintained themselves for a time as stock plays. Most men of letters essayed tragedy,--Addison, Johnson, Young, Thomson, Gay, the laureates Cibber, Rowe, Whitehead, Pye, and a host of minor celebrities. Besides the tragedies acted, there were almost as many not acted but printed. Closet dramas, common in the Elizabethan period, grew more numerous after the Restoration. Whether the writer scorned or was scorned by the manager, an appeal to the reading public was always easy and apparently sometimes profitable. Tragedies were bought and read; a popular play might start with an edition of five thousand and run through a number of editions. Even after the novel had supplanted the drama among readers, there was no diminution of printed plays. The non-acted plays, however, offer nothing of importance for the history of the drama. The majority are unactable; others follow the usual formulas; a few Greek plays, alterations of Shakespeare, and sacred dramas have some interest as curiosities. The increase in the number of these plays does indicate a growing separation between the drama and the theatre. Plays were no longer written by a set of dramatists who made a profession; they were written by any one who had literary pretensions. Only a few new plays were required; the supply greatly exceeded the demand. The theatrical monopoly maintained by the two patented theatres offered no great encouragement to dramatists, and the number who wrote without any acquaintance or knowledge of the stage increased. Literary fame rather than success in the theatre was perhaps the greater incentive in the case of tragedy. Whatever the incentive, individual ambition resulted in no individuality of expression. The popular ballad of tradition is scarcely less expressive of personality than the average eighteenth century tragedy. Even the plays of temporary importance have no flavor of their own.[37]
