This is a unique and unclassifiable book, part novel, part travel book, part notebook full of quotations and speculations. Chatwin focuses on the notion that language and human thought began in songs that sang the landscape and living things into existence. Aboriginal culture continues this tradition in songlines which are explored as living entities, maps, boundaries, calendars, catalogues, survival systems, myths. Chatwin says the ultimate question he is asking is, why are humans so restless? He argues that this is the ultimate human quality. We are nomadic in our core. He quotes a European tramp: "It's like the tides were pulling you along the highway. I'm like the Arctic tern, guv'nor...what flies from the North Pole to the South Pole and back again." This book doesn't provide answers. Indeed it plunges into even wider speculations about war, prehistory, mythology and culture. But it goes far beyond the predictable "Aboriginal wisdom for the westerner" that I expected. A fascinating, difficult, but intriguing book.
