This volume celebrates the work of Dr. Phil. h.c. Gerhard Milstreu in his 40th year as director of Tanum Museum of Rock Carving and Rock Art Research Centre, Undersloes, Sweden. Here, a feast of scholarly contributions from across Europe, at all levels of study have been collected. Each and every one of the chapters addresses aspects connected to the work Gerhard has done over the last 40 years. Through their words and images, these pay respect to and acknowledge Gerhard's achievements in the fields of rock art documentation, research, international collaboration and outreach. Gerhard has striven from the outset to: promote the importance of the image within archaeology, increase public interest and involvement with prehistoric art, and to encourage the next generation to continue the work. Thus, many authors think very deeply about the images, how we interpret them and how we record them, particularly in light of recent advances in technology. Others explore how Gerhard has fostered dissemination and public involvement. The range of countries and subjects represented; France, Italy, Holland, Norway, Sweden, Denmark and the UK; reflects the success of Gerhard's focus on international collaboration and dialogue. Given Gerhard's emphasis on giving the past a future, it is appropriate that leading up and coming scholars, from all levels of higher education, are also present and have the opportunity to present their latest research.
