With a very literary style and an unusual depth in current archaeology, Olivier makes a journey between metaphor and reality that questions archaeology as a discipline, in a positive way, highlighting that fundamental aspect as a science of "constantly recomposed memories." There, in the complex sphere of temporality, he shows us how archaeology is a discipline of the present that recovers memories from those remains that we recover like "rags from the past." It is a complex and stimulating book. In the prologue's words: "An unforgettable book that every professional archaeologist should read even if it is only to (re) think the fundamentals of what we do."
