introduction to the Fantasy genre in literature, media and culture, this incisive volume explores why Fantasy matters in the context of its unique affordances, its disparate pasts and its extraordinary current flourishing. It pays especial attention to Fantasy's engagements with histories and traditions, its manifestations across media and its dynamic communities. Matthew Sangster covers works ancient and modern; well-known and obscure; and ranging in scale from brief poems and stories to sprawling transmedia franchises. Chapters explore the roles Fantasy plays in negotiating the beliefs we live by; the iterative processes through which fantasies build, develop and question; the root traditions that inform and underpin modern Fantasy; how Fantasy interrogates the preconceptions of realism and Enlightenment totalisations; the practices, politics and aesthetics of world-building; and the importance of Fantasy communities for maintaining the field as a diverse and ever-changing commons.
