Book excerpt: It is always interesting to read studies of insular or isolated groups or environments, and to speculate on why they do not tend to mirror changes in neighbouring areas. This book studies the archaeological evidence during the period 3000-800 BC, the settlements, cemeteries, artefacts and environment of each individual island. In a concluding chapter the islands are studied as a group looking at general sequences of historical and cultural development and the role of foreign, outside influences in accounting or contributing to these changes. A clear and well illustrated archaeological study.
