The early essay in English was a fluid and malleable form. It was thus ‘fugitive’: it could be deeply topical, fleeting, and perishable, taking up the ephemeral and the occasional, and could easily travel across media from reader to reader given its portability. This chapter studies how writers exploited the affordances of the essay, first in seventeenth-century newsbooks and pamphlets, and then in early eighteenth-century periodicals. It retraces the origins of the English newsbook in a highly regulated media ecology, and examines the essayistic writings of Marchamont Nedham as a case study in stylistic innovation and rhetorical self-fashioning. During the era of licensing (1662–95) and the first decades of the eighteenth century, essayists continued to adapt the form, finding in the emergent print media of this period a ready site for politics and polemic.
