This textbook provides a global, chronological mapping of significant areas of theatre, sketched from its deepest history in the evolution of our brain's 'inner theatre' to ancient, medieval, modern, and postmodern developments. It considers prehistoric cave art and built temples, African trance dances, ancient Egyptian and Middle-Eastern ritual dramas, Greek and Roman theatres, Asian dance-dramas and puppetry, medieval European performances, global indigenous rituals, early modern to postmodern Euro-American developments, worldwide postcolonial theatres, and the hyper-theatricality of today's mass and social media. Timelines and numbered paragraphs form an overall outline with distilled details of what students can learn, encouraging further explorations online and in the library. Questions suggest how students might reflect on present parallels, making their own maps of global theatre histories, regarding geo-political theatrics in the media, our performances in everyday life, and the theatres inside our brains.
