The essays in this book are gathered together from the realms of art, literature, history, archaeology, philosophy and science. Together they weave a picture that gives us new insights into the mirror as a material object and as an image in art and texts. This interdisciplinary and innovative book raises important issues about the material life of an object and its intimate interrelations with socio-cultural imagery. Perceptions of the workings of our cognitive processes and of our subjectivity are shown to be dynamically interwoven with the technological and socio-cultural matrices of particular periods, whilst longer term continuities in the understanding and employment of the mirror reflect underlying continuities in the capacities and constraints of mirrors and of human subjects. This book demonstrates the active role imagery and technologies have always played in our thoughts, lives and worlds.
