Chapter Five explores the early modern phenomenon of girls “putting on” the minds of others. It argues that, when they engaged in these acts of cognitive play, girls were able to try on alternative perspectives and experiences — not necessarily male ones, but those that belonged to sexually active females: the lover, the harlot, the pregnant woman. It focuses on the girls from John Lyly’s Gallathea, Shakespeare’s The Winter’s Tale, and Margaret Cavendish’s The Convent of Pleasure, all of whom costume their bodies and put on the minds of sexually experienced females. Their performances allow them to project themselves into these roles without actually becoming “women” in a heteronormative sense that would require their bodies to transform through penetrative intercourse, pregnancy, or birth. The girls who dress up in these plays do so under different levels of duress, but they all share an ability to use their brainwork to manipulate the Protestant girl-to-woman script they were expected to follow — to resist, revise and, in some cases, reject it.
