昨年12月に刊行された1604年版（A-text）に続く『フォースタス博士』のB-text版。序文では古版本の印刷・出版に関する詳細なデータを提供し、1616年版の本文に施された「加筆と改訂」について詳述する。これまで不明であった印刷所の特定に世界ではじめて成功。鍵となる役を演じた俳優を実名で同定する。The Tragical History of the Life and Death of Doctor Faustus (1616) has been a cause of controversy ever since its publication, not least because of problems about its relationship to the text published in 1604. Whilst the bulk of the play is ascribed to Christopher Marlowe, payment was made to William Bird and Samuel Rowley for additional comic episodes, printed for the first time in the fourth Quarto, which expanded the text by about one third. There are numerous other differences between the two texts. The editor's introduction provides a full bibliographical analysis of the text, including important new information about its printer. Possible reasons for the revisions of, and additions to, the text are considered, including changes in acting personnel, censorship, and audience expectations.
