Theories of Vision from Al-kindi to Kepler


Book Description

Kepler's successful solution to the problem of vision early in the seventeenth century was a theoretical triumph as significant as many of the more celebrated developments of the scientific revolution. Yet the full import of Kepler's arguments can be grasped only when they are viewed against the background of ancient, medieval, and Renaissance visual theory. David C. Lindberg provides this background, and in doing so he fills the gap in historical scholarship and constructs a model for tracing the development of scientific ideas. David C. Lindberg is professor and chairman of the department of the history of science at the University of Wisconsin, Madison.




The Beginnings of Western Science


Book Description

When it was first published in 1992, The Beginnings of Western Science was lauded as the first successful attempt ever to present a unified account of both ancient and medieval science in a single volume. Chronicling the development of scientific ideas, practices, and institutions from pre-Socratic Greek philosophy to late-Medieval scholasticism, David C. Lindberg surveyed all the most important themes in the history of science, including developments in cosmology, astronomy, mechanics, optics, alchemy, natural history, and medicine. In addition, he offered an illuminating account of the transmission of Greek science to medieval Islam and subsequently to medieval Europe. The Beginnings of Western Science was, and remains, a landmark in the history of science, shaping the way students and scholars understand these critically formative periods of scientific development. It reemerges here in a second edition that includes revisions on nearly every page, as well as several sections that have been completely rewritten. For example, the section on Islamic science has been thoroughly retooled to reveal the magnitude and sophistication of medieval Muslim scientific achievement. And the book now reflects a sharper awareness of the importance of Mesopotamian science for the development of Greek astronomy. In all, the second edition of The Beginnings of Western Science captures the current state of our understanding of more than two millennia of science and promises to continue to inspire both students and general readers.




Alhacen's Theory of Visual Perception


Book Description

Sometime between 1028 and 1038, Ibn al-Haytham completed his monumental optical synthesis, Kitab al-Manazir ("Book of Optics"). By no later than 1200, and perhaps somewhat earlier, this treatise appeared in Latin under the title De aspectibus. In that form it was attributed to a certain "Alhacen." These differences in title and authorial designation are indicative of the profound differences between the two versions, Arabic and Latin, of the treatise. In many ways, in fact, they can be regarded not simply as different versions of the same work, but as different works in their own right. Accordingly, the Arab author, Ibn al-Haytham, and his Latin incarnation, Alhacen, represent two distinct, sometimes even conflicting, interpretive voices. And the same holds for their respective texts. To complicate matters, "Alhacen" does not represent a single interpretive voice. There were at least two translators at work on the Latin text, one of them adhering faithfully to the Arabic original, the other content with distilling, even paraphrasing, the Arabic original. Consequently, the Latin text presents not one, but at least two faces to the reader. This two-volume critical edition represents fourteen years of work on Dr. Smith's part. Awarded the 2001 J. F. Lewis Award.




From Sight to Light


Book Description

From its inception in Greek antiquity, the science of optics was aimed primarily at explaining sight and accounting for why things look as they do. By the end of the seventeenth century, however, the analytic focus of optics had shifted to light: its fundamental properties and such physical behaviors as reflection, refraction, and diffraction. This dramatic shift—which A. Mark Smith characterizes as the “Keplerian turn”—lies at the heart of this fascinating and pioneering study. Breaking from previous scholarship that sees Johannes Kepler as the culmination of a long-evolving optical tradition that traced back to Greek antiquity via the Muslim Middle Ages, Smith presents Kepler instead as marking a rupture with this tradition, arguing that his theory of retinal imaging, which was published in 1604, was instrumental in prompting the turn from sight to light. Kepler’s new theory of sight, Smith reveals, thus takes on true historical significance: by treating the eye as a mere light-focusing device rather than an image-producing instrument—as traditionally understood—Kepler’s account of retinal imaging helped spur the shift in analytic focus that eventually led to modern optics. A sweeping survey, From Sight to Light is poised to become the standard reference for historians of optics as well as those interested more broadly in the history of science, the history of art, and cultural and intellectual history.




A Natural History of Vision


Book Description

This illustrated survey covers what Nicholas Wade calls the "observational era of vision," beginning with the Greek philosophers and ending with Wheatstone's description of the stereoscope in the late 1830s.




Seeing and Being Seen in the Later Medieval World


Book Description

During the later Middle Ages people became increasingly obsessed with vision, visual analogies and the possibility of visual error. In this book Dallas Denery addresses the question of what medieval men and women thought it meant to see themselves and others in relation to the world and to God. Exploring the writings of Roger Bacon, Duns Scotus, Peter Aureol and Nicholas of Autrecourt in light of an assortment of popular religious guides for preachers, confessors and penitents, including Peter of Limoges' Treatise on the Moral Eye, he illustrates how the question preoccupied medieval men and women on both an intellectual and practical level. This book offers a unique interdisciplinary examination of the interplay between religious life, perspectivist optics and theology. Denery presents significant new insights into the medieval psyche and conception of the self, ensuring that this book will appeal to historians of medieval science and those of medieval religious life and theology.




Visual Perception


Book Description

Vision is our most dominant sense, from which we derive most of our information about the world. From the light that enters the eye and the processing in the brain that follows we can sense where things are, how they move and what they are. The first edition of Visual Perception took a refreshingly different approach to perception, starting from the function that vision serves for an active observer in a three-dimensional environment. This fully revised and expanded new edition continues this approach in contrast to the traditional textbook treatment of vision as a catalogue of phenomena. Following a general introduction to the main theoretical approaches, the authors discuss the historical basis of our current knowledge. Placing the study of vision in its historical context, they look at how our ideas have been shaped by art, optics, biology and philosophy as well as psychology. Visual optics and the neurophysiology of vision are also described. The core of the book covers the perception of location, motion and object recognition. There is a new chapter on representation and vision, including a section on the perception of computer generated images. This readable, accessible and truly relevant introduction to the world of perception aims to elicit both independent thought and further study. It will be welcomed by students of visual perception and those with a general interest in the mysteries of vision.




Sight, Touch, and Imagination in Byzantium


Book Description

Considering the interrelations between sight, touch, and imagination, this book surveys classical, late antique, and medieval theories of vision to elaborate on how various spheres of the Byzantine world categorized and comprehended sensation and perception. Revisiting scholarly assumptions about the tactility of sight in the Byzantine world, it demonstrates how the haptic language associated with vision referred to the cognitive actions of the viewer as they grasped sensory data in the mind in order to comprehend and produce working imaginations of objects for thought and memory. At stake is how the affordances and limitations of the senses came to delineate and cultivate the manner in which art and rhetoric was understood as mediating the realities they wished to convey. This would similarly come to contour how Byzantine religious culture could also go about accessing the sacred, the image serving as a site of desire for the mediated representation of the Divine.




Mirrors of the Divine


Book Description

"There has long been a curious fascination with eyes and mirrors as evident throughout art, film, and literature. From fantastical characters who shoot lasers from their eyes to those whose memories are altered visually, the way in which a story portrays the function of the eyes demonstrates the way the storyteller imagines the character's relationship to the world. Is the character powerful or powerless? Does she impact her world or is she impacted by that world? The storyteller's portrayal of vision answers those questions and reveals deeper assumptions about the individual and her ability to move within and to know her world. While eyes are associated with interacting with this world, mirrors are distinctly associated with interacting with some other world. Mirrors function as portals to other worlds, windows that glimpse an alternate reality, or harmful traps that hide sinister intentions. How an author portrays eyes reveals how she understands the world, while how she portrays mirrors reveals how she imagines the unknown"--
