Shakespeare and authorial networks in early modern drama examines how intertextual exchanges shaped Shakespeare’s plays. Drawing on social network theory, it traces his sustained creative dialogue with Michael Drayton, John Marston and George Chapman, showing how shared discourses at cultural institutions and within patronage families informed recurring topics across their works. The study argues that Shakespeare’s engagement with institutional and social environments did not require direct membership or patronage; instead, looser ties influenced his authorship. By revealing how thematic and stylistic developments emerged through long-term conversations among playwrights, the book offers new insight into Shakespeare’s writing process and collaborative practices. It provides alternative models of authorship, influence and literary exchange that nuance conventional accounts of early modern patronage and highlight the significance of networks in shaping dramatic production.
