"A sweeping account as tangled and chaotic--and fascinating--as the dreams themselves . . . It reinfuses the dreamscape with beauty, mystery and significance . . . The Oracle of Night takes a breakneck journey through history, from cave paintings and the ancient Greeks to Celtic myths, Egyptian pharaohs, Gilgamesh and Julius Caesar. The text, translated from the Portuguese by Daniel Hahn, moves fluidly from systemic historiography to guesswork and lighthearted extrapolation . . . The result is a curiously hybridized book, at times playful, at times intensely scientific . . . Poetic and visceral."
--The Wall Street Journal

"The Oracle of Night makes a resounding case for the mystery, beauty and cognitive importance of dreams . . . This book is the culmination of decades of thought and collaborative work. It's also the expression of remarkable, if sometimes all-over-the-map, scholarship, drawing on history, literature, biology, anthropology, neuroscience, sociology and psychology, among other disciplines . . . [Ribeiro's] lyrical account is aided by Daniel Hahn's beautiful translation from the Portuguese . . . You can't help being awed and enchanted by the wonder with which Ribeiro approaches his subject, by the depth of his knowledge and passion."
--The New York Times

"[Ribeiro] explores hypotheses about the evolutionary value of sleep to humans, presenting a fascinating analysis of the debate about the relationship between sleep and cognitive ability . . . concluding, among other things, that nap rooms would be a valuable addition to school environments."
--Publishers Weekly

"A comprehensive consideration of the sleeping mind . . . [Ribeiro] offers a capacious examination of the phenomenon of dreaming. The author draws on biology, chemistry, neurophysiology, anthropology, mythology, history, literature, biography, and art--along with myriad examples of dream narratives--to create a rich history of the human mind . . . A stimulating and informative overview."
--Kirkus Reviews

"A groundbreaking history of the human mind told through our experience of dreams--from the earliest accounts to current scientific findings--and the essential role of dreams in the formation of who we are and the world we have made."
