by the Irish High Court judge and antiquarian William O'Brien in the 1880s. It was put up for auction by Sotheby's in 2017. The Fourth Folio appeared in 1685, published by R. Bentley, E. Brewster, R. Chiswell, and H. Herringman. It contains the same 43 plays as the Third Folio. Brewster, Chiswell, and Herringman were members of the six-man syndicate that published the third Ben Jonson folio in 1692; Herringman was one of three stationers who issued the second Beaumont and Fletcher folio in 1679. The Fourth Folio in turn served as the base for the series of eighteenth-century editions of Shakespeare's plays. Nicholas Rowe used the Fourth Folio text as the foundation of his 1709 edition, and subsequent editors — Pope, Theobald, etc. — both adapted and reacted to Rowe's text in their own editions. (See: Shakespeare's editors.) The Two Noble Kinsmen did not appear in any Folio edition. It was not printed until 1634, although there is evidence of its being performed much earlier. The title page said "written by the memorable worthies of their time: Mr. John Fletcher and Mr. William Shakspeare [sic], Gent." It was not included in most editions of Shakespeare (e.g., the Cambridge/Globe editions of Wright and Clark, ca. 1863) until the latter half of the 19th century (it appears, e.g., in Dyce's collected Works of Shakespeare in 1876) but it was not generally accepted into the Shakespeare canon until well into the 20th century, when, for example, it was included in the Riverside edition of 1974.
