The early modern English masque is a hybrid form of entertainment that included music, dance, poetry, and visual spectacle, and for which there is no modern equivalent. This dissertation looks at four incarnations of the Elizabethan and Jacobean masque: the court masque, the masque embedded in the progress entertainment, the masque embedded in the commercial play, and the masque embedded in the commercial play performed at court. This study treats masques as a form of elite theatre (that is, theatre for, by, and about elite figures like monarchs and aristocrats) and follows them from the court to the countryside, through the commercial playhouse, and back again to the court in pursuit of a more nuanced picture of the hybridity and flexibility of early modern English performance culture.
