Drawing is not just an art form: it is a way of both thinking of and being in the world. How drawing is used by scientists, anthropologists, medical researchers and how artists have become involved in those disciplines is a rich and complex subject. This book, with its attentiveness to the lives and particular approaches of artists and other people who draw to understand, is invaluable. Not only does it show how drawing can be used as an investigative tool, it also broadens and deepens our understanding of drawing as an art form. -- Tony Godfrey, Independent Scholar, Philippines This is a fascinating and timely study into the diverse and dynamic practices of drawing. Few practitioner-academics are as well placed as Casey and Davies to roam so broadly and imaginatively into the rich territory of drawing. What is so rewarding about this particular volume is the diversity of perspectives from the linear objectivity required by the archaeologist to the graphic innovation pioneered by contemporary artists. A much-needed addition to the rather under-nourished field of enquiry into drawing and its practices. -- Professor Paul Gough, Vice-Chancellor of Arts University Bournemouth, UK
