Ancient and medieval labyrinths embody paradox, according to Penelope Reed Doob. Their structure allows a double perspective—the baffling, fragmented prospect confronting the maze-treader within, and the comprehensive vision available to those without. Mazes simultaneously assert order and chaos, artistry and confusion, articulated clarity and bewildering complexity, perfected pattern and hesitant process. In this handsomely illustrated book, Doob reconstructs from a variety of literary and visual sources the idea of the labyrinth from the classical period through the Middle Ages. Doob first examines several complementary traditions of the maze topos, showing how ancient historical and geographical writings generate metaphors in which the labyrinth signifies admirable complexity, while poetic texts tend to suggest that the labyrinth is a sign of moral duplicity. She then describes two common models of the labyrinth and explores their formal implications: the unicursal model, with no false turnings, found almost universally in the visual arts; and the multicursal model, with blind alleys and dead ends, characteristic of literary texts. This paradigmatic clash between the labyrinths of art and of literature becomes a key to the metaphorical potential of the maze, as Doob's examination of a vast array of materials from the classical period through the Middle Ages suggests. She concludes with linked readings of four "labyrinths of words": Virgil's Aeneid, Boethius' Consolation of Philosophy, Dante's Divine Comedy, and Chaucer's House of Fame, each of which plays with and transforms received ideas of the labyrinth as well as reflecting and responding to aspects of the texts that influenced it. Doob not only provides fresh theoretical and historical perspectives on the labyrinth tradition, but also portrays a complex medieval aesthetic that helps us to approach structurally elaborate early works. Readers in such fields as Classical literature, Medieval Studies, Renaissance Studies, comparative literature, literary theory, art history, and intellectual history will welcome this wide-ranging and illuminating book.

The mechanism by which photoreceptor cells in the eyes of higher animals absorb light, giving rise to receptor potentials that initiate the visual process, is a subject of active research in biophysics today. The pace of this research and its multidisciplinary nature have made it difficult for the nonexpert to keep abreast of new discoveries. This book aims to provide a more coherent, compact summary of our knowledge about the field that has been available, serving as an up-to-date introduction to the role of photoreceptors in vision. The book is a self-contained, concise handbook for the reader who has at least a college level knowledge if cell biology, biochemistry, physical chemistry, neurobiology and physics. The authors describe the physical parameters of light and proceed to describe the mechanisms by which photoreceptors extract information about each parameter. The discussion of mechanisms is organized by discipline, following the general sequence of cellular morphology, visual pigment chemistery, and receptor physiology. Photoreceptors: their role in vision is an integrated sourcebook which will serve the novice as a 'stepping stone' to the vast and exciting scientific literature of the field.

This textbook is intended for use in a course for undergraduate students in biology, neuroscience or psychology who have had an introductory course on the structure and function of the nervous system. Its primary purpose is to provide a working vocabulary and knowledge of the biology of vision and to acquaint students with the major themes in biological vision research. Part I treats the eye as an image-forming organ and provides an overview of the projections from the retina to key visual structures of the brain. Part II examines the functions of the retina and its central projections in greater detail, building on the introductory material of Part I. Part III treats certain special topics in vision that require this detailed knowledge of the structure and properties of the retina and visual projections.

One of the most persistent controversies of modern science has dealt with human visual perception. It erupted in Germany during the 1860s as a dispute between physiologists Hermann von Helmholtz, Ewald Hering, and their schools. Well into the twentieth century these groups warred over the origins of our capacity to perceive space, over the retinal mechanisms that mediate color sensations, and over the role of mind, experience, and inference in vision. Here R. Steven Turner explores the impassioned exchanges of those rival schools, both to illuminate the clash of theory and to explore the larger role of controversy in the development of science. Controversy, he suggests, is constitutive of scientific change, and he uses the Helmholtz-Hering dispute to illustrate how polemics and tacit negotiation shape evolving theoretical stances. Turner focuses on the arguments and issues of the dispute, issues that ranged from the interpretation of color blindness and optical illusions to the therapeutic practices of clinical ophthalmology. As well, he focuses on the personalities, institutions, disciplinary structures, and methodological commitments that shaped the dispute, including the schools' rhetorical strategies. He explores the incommensurability of the protagonists' viewpoints and examines the reception of the theories and the changing fortunes of the schools. Finally, Turner traces the controversy into the twentieth century, where the issues continue to inform the study of vision today. Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
