This analysis of Shakespeare's sonnets in relation to his plays asserts that the language of the sonnets is primarily performative rather than descriptive. It discusses the 1609 quarto of sonnets and the Petrarchan discourses in a selection of plays. David Schalkwyk addresses embodiment and silencing, interiority and theatricality, inequalities of power, status, gender and desire in the published poems, on the stage and in the context of the early modern period.
