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.

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.

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.

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.

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.

This book clarifies the interrelationship between optics, vision and perspective before the Classical Age, examining binocularity in particular. The author shows how binocular vision was one of the key juncture points between the three concepts and readers will see how important it is to understand the approach that scholars once took. In the Middle Ages and the Renaissance, the concept of Perspectiva – the Latin word for optics – encompassed many areas of enquiry that had been viewed since antiquity as interconnected, but which afterwards were separated: optics was incorporated into the field of physics (i.e., physical and geometrical optics), vision came to be regarded as the sum of various psycho-physiological mechanisms involved in the way the eye operates (i.e., physiological optics and psychology of vision) and the word ‘perspective’ was reserved for the mathematical representation of the external world (i.e., linear perspective). The author shows how this division, which emerged as a result of the spread of the sciences in classical Europe, turns out to be an anachronism if we confront certain facts from the immediately preceding periods. It is essential to take into account the way medieval scholars posed the problem – which included all facets of the Latin word perspectiva – when exploring the events of this period. This book will appeal to a broad readership, from philosophers and historians of science, to those working in geometry, optics, ophthalmology and architecture.
