Book excerpt: "Of all Lepage's magic boxes, this is the masterpiece" (Independent on Sunday) Early one August morning in 1945, several kilos of uranium dropped over Japan changed the course of human history. Fifty years later, Hiroshima's vitality is striking: the city where survival itself seemed unimaginable today incarnates the notion of renaissance. Robert Lepage and Ex Machina's The Seven Streams of the River Ota makes Hiroshima a literal and metaphoric site for theatrical journey through the last half-century. In The Seven Streams, Hiroshima is a mirror in which seeming opposites - East and West, tragedy and comedy, male and female, life and death - are revealed as reflections of the same reality.
