Earth is My Mother, Sky is My Father: Space, Time, and Astronomy in Navajo Sandpainting is beautifully illustrated by the author, Trudy Griffin-Pierce. This well-documented book explores the spiritual world of the Navajo, their ceremonial practices, and their conceptions of time and stellar motion. Griffin-Pierce shows how the images of sacred sandpaintings not only communicate the temporal and spatial dimensions of the Navajo universe but also present, in visual form, Navajo ideas about relationships among nature, self, and society. Foreword by N. Scott Momaday. Includes 8 photographs, 50 drawings and a map.
