What does rock art say about gender and how can our understanding of gender shape the way that we view rock art? A significant contribution to the relatively unexplored field of gender in rock art, this volume contains a wealth of information for archaeologists, anthropologists, and art historians interested in past gender systems. Hays-Gilpin argues that art is at once a product of its physical and social environment and at the same time a tool of influence in shaping behavior and ideas within a society.

Subsequently issues of representation and the people who made these forms of art are also discussed.
