For Renaissance playwrights, collaboration appears to have been the norm; Bently notes that nearly two-thirds of plays mentioned in Henslowe's papers reflect the participation of more than one writer. There is also an issue of continuous revision: it was common practice in Renaissance English theatre for professional writers attached to a company to compose new characters, scenes, prologues and epilogues for plays in which they did not originally have a hand. Scott McMillin has exported revision as a deconstruction of authorial individuality in the Sir Thomas More manuscript.
