A Companion to Rock Art Edited by Jo McDonald and Peter Veth Wiley Blackwell, 2012 ISBN 978-1-4443-3424-1. Pp. xxxiv+680. 133.30 [pounds sterling]. This international volume on rock art provides a complete, comprehensive and up-to-date overview of most of the main research theories and methods used, and the research questions addressed, in current archaeological debates on rock art, be they global or regional. It was conceived by the editors as a tool teaching the next generation of rock art researchers in a 13-week semester cycle. But this volume is more than a collection of educational materials. It gathers research papers addressing some key topics in rock-art studies, and thus becomes essential reading for anyone interested and/or conducting rock-art research today. The 37 contributions by 57 international scholars from five continents are structured into 11 meaningful sections, with two to four papers per section. While the chapters in each section are intended to address a specific issue, well defined by the section headings (I. Explanatory frameworks; II. Inscribed landscapes; III. Rock art at the regional level; IV. Engendered approaches; V. Form, style and aesthetics; VI. Contextual rock art; VII. The mediating role of rock art; VIII. Rock art, identity and indigeneity; IX. Rock art management and interpretation, X. Dating rock art, XI. Rock art in the digital age), some key questions are explored recursively across the volume. This shows their significance for achieving a more complete understanding of rock art, as a tool for exploring past and present human behaviour and cultural practices. Questions of time (relative or chronometric), place, past and present as well as individual and group identities, function and/or meaning are explored through the systematic deconstruction and analysis of the motifs, themes and panels, their patterns of variation, the context and/or the landscapes, from a variety of international perspectives and backgrounds. Case studies from Australia and the Pacific, Northern and Southern America, Siberia, Europe, Africa and India, and a wide range of periods, from the European Upper Palaeolithic to current Australian rock art, fully illustrate these questions. All these studies remind us once more that rock art is not only about the decoration of passive surfaces with beautiful images, as emphasised by Blinkhorn et al. in chapter 11. Rock art is an alternative source of information about human behaviour and practices, and can be used to explore continuities and discontinuities, human interaction, past territoriality, group mobility, symbolic behaviour and so forth. The large number of chapters prevents us from briefly summarising each of them, but some key issues for current debates are worth mentioning. Of special interest for interpretative approaches is Lewis-Williams' reflective contribution (chapter 2) on the misinterpretation and misuse of his concept of to universally interpret rock art. As he states, shamanism is only one of the many potential interpretations of rock art, and thus it cannot be systematically used to interpret past arts. While past interpretative trends used to emphasise a unique function for Pleistocene art (for a brief summary of past interpretative schools, see Moro and Gonzalez, chapter 15), current studies recognise the multiple functions of past and present imagery and the variety of social contexts (religious, social and political) in which art operates. Take as an example the multiple functions of Western Desert People's rock art, summarised by McDonald and Veth (chapter 6: 96), which includes marking place and individual's affiliation, storytelling or instructive purposes, initiation ceremonies, visual representation of an ancestral being or event, and so forth. It is fully accepted throughout the volume that only through a thoughtful analysis and understanding of the context of rock art (the walls, the surrounding archaeological site, the geographical context, the acoustic or other sensorial properties, etc. …
