Sometimes the writing of history seems to float free of its grounding in archaeological and documentary data, offering (albeit necessary) abstractions when we require detailed and concrete records. This is not, however, the case in the volume under review. In Negotiating Cultures, the reader enjoys a coherent perspective on textual data in all their complexity and meticulously rendered: the discovery of a lost document in the Archives of the Crown of Aragon (Barcelona); edition and translation of texts; dating; identification of names of places and personalities; and all kinds of complementary tasks that lead to a historical contextualization and analytical study.
