That Shakespeare thematized time thoroughly, almost obsessively, in his plays is well established: time is, among other things, a 'devourer' (Love's Labour's Lost), one who can untie knots (Twelfth Night), or, perhaps most famously, simply ‘out of joint’ (Hamlet). Yet most critical commentary on time and Shakespeare tends to incorporate little focus on time as an essential - if elusive - element of stage praxis. This book aims to fill that gap; Wagner's focus is specifically performative, asking after time as a stage phenomenon rather than a literary theme or poetic metaphor.
