The study of repertory has greatly illuminated practices among playwrights and playing companies in the later sixteenth century. The repertory approach has yet to be applied to early and mid-Tudor drama, although this method holds out the promise of recovering the collaborative practices connected with John Rastell's stage-the first public stage in London. This article urges scholars active in repertory studies to take a fresh look at Henrician drama and theatrical practices, and employs Heywood and Rastell's play Gentylnes and Nobylyte as a case study in the forces that shaped repertory in this earlier period. In the past twenty-five years the emergence and growth of repertory studies-greatly enabled by the discoveries of the Records of Early English Drama project-has enriched our understanding of the interrelations among playing, playwriting, and performance practices on Elizabethan and Stuart stages. 1 As a method of inquiry, the study of repertory employs 'literary-critical, bibliographical, and theatrical' approaches 2 that focus not only on plays as texts, but also on plays as material artifacts that raise and respond to questions regarding a host of theatrical mysteries. Repertory methods have yet to be applied to early and mid-Tudor drama even though this perspective holds out the possibility of illuminating vexed issues concerning patronage, performance space, performance practice, spectatorship, and authorshipparticularly collaborative authorship. For works from this period, authorship is frequently difficult to determine, but it is useful to analyze plays with contested attribution for the clues they may hold to the practices of playwrights and producers and the collaborative networks within which they operated. 3 This essay examines the playwriting and producing activities of John Rastell and his network in light of such repertorial considerations. Although London theatrical practices changed radically with the development of the later sixteenth-century professional playing companies and commercial theatres, the roots of later stage practices are traceable to the activities of earlier playwrights, players, and patrons. Indeed, the development and
