From the patristic age until the Gregorian calendar reform of 1582, computus -- the science of time reckoning and art of calendar construction -- was a matter of intense concern. Bede's The Reckoning of Time (De temporum ratione) was the first comprehensive treatise on this subject and the model and reference for all subsequent teaching discussion and criticism of the Christian calendar. It is a systematic exposition of the Julian solar calendar and the Paschal table of Dionysius Exiguus, with their related formulae for calculating dates. But it is more than a technical handbook. Bede sets calendar lore within a broad scientific framework and a coherent Christian concept of time, and incorporates themes as diverse as the theory of tides and the doctrine of the millennium.

This translation of the full text of The Reckoning of Time includes an extensive historical introduction and a chapter-by-chapter commentary. It will interest historians of medieval science, theology, and education, Bede scholars and Anglo-Saxonists, liturgists, and Church historians. It will also serve as an accessible introduction to computus itself. Generations of medieval computists nourished their expertise in Bede's orderly presentation; modern scholars in quest of safe passage through this complex terrain can hope for no better guide.

The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its development is one of the great untold stories of science and history.

How did Pope Gregory set right a calendar which was in error by at least ten lull days? What did time mean to a farmer on the Rhine in 800 A.D.?

For over two and a half millennia human beings have attempted to invent strategies to "discover" the truth of time, to determine whether time is infinite, whether eternity is the infinite duration of a continuous present, or whether it too rises and falls with the cycles of universal creation and destruction. Time-Fetishes recounts the history of a tradition that runs counter to the dominant tradition in Western metaphysics, which has sought to purify eternity of its temporal character. From the pre-Socratics to Ovid and Plotinus, and from Shakespeare to Hegel, Schelling, Nietzsche, Heidegger, and Derrida, Time-Fetishes traces the secret tradition of the idea of eternal recurrence and situates it as the grounding thought of Western philosophy and literature. The thinkers in this counter-history of the eternal return lingered long enough on the question of time to learn how to resist separating eternity from time, and how to reflect on the possible identity of time and eternity as a way of resisting all prior metaphysical determinations. Drawing out the implications of Nietzsche's reinvention of the doctrine of return, Lukacher ranges across a broad spectrum of ancient and modern thinkers. Shakespeare's role in this history as the "poet of time" is particularly significant, for not only does Shakespeare reactivate the pre-Christian arguments of eternal return, he regards them, and all arguments and images concerning the essence of time and Being, from an inimitably ironic perspective. As he makes transitions from literature to philosophy and psychoanalysis, Lukacher displays a theoretical imagination and historical vision that bring to the forefront a host of pre- and post-Christian texts in order to decipher in them an encounter with the thought of eternal recurrence that has been too long buried under layers of rigid metaphysical interpretation.

All religion and much philosophy has been concerned with the contrast between the ephemeral and the eternal. Human beings have always sought ways to overcome time, and to prove that death is not the end. This book consists then in an exploration of certain closely related ideas: personal identity, time, history and our commitment to the future, and the role of imagination in life.

Warnock argues in particular that the notion of personal immortality, as it appears in Christian dogma, cannot be taken literally. Nevertheless, as a metaphor, immortality may illuminate both our relation with the past, our understanding of the present and our responsibility for the future. In the course of the argument, philosophical themes of personal identity, of history, and of values, are explored, as well as the cognitive content of the imagination.

In this second English-language edition of one of his most notable works, Miguel Leon-Portilla explores the Maya Indians' remarkable concepts of time. At the book's first appearance Evon Z. Vogt, Curator of Middle American Ethnology in Harvard University, predicted that it would become "a classic in anthropology," a prediction borne out by the continuing critical attention given to it by leading scholars.

Like no other people in history, the ancient Maya were obsessed by the study of time. Their sages framed its cycles with tireless exactitude. Yet their preoccupation with time was not limited to calendrics; it was a central trait in their evolving culture.

In this absorbing work Leon-Portilla probes the question, What did time really mean for the ancient Maya in terms of their mythology, religious thought, worldview, and everyday life? In his analysis of key Maya texts and computations, he reveals one of the most elaborate attempts of the human mind to penetrate the secrets of existence.

Why does time appear to run in only one direction? We remember the past- but why not the future? We can influence the future- but could we, even theoretically, influence the past?

Generations of philosophers and theologians, physicists and mathematicians have puzzles and speculated about these and the many other questions that surround the concept of time. Recent scientific work is said to explain the directionality of time. But time still contains many mysteries- black holes and big bangs, asymmetries and relativities, arrows and loops - that will doubtless continue to occupy us for centuries to come.

In this impressive collection of original articles ten internationally known scholars explore and explains the nature of time, apace and now space-time. Founded on the latest developments in thermodynamics, quantum theory and cosmology, their ideas will fascinate anyone interested in Einstein's theory of relativity.

"A discussion of the historical development of our ideas of time as they relate to nature, human nature and society. . . . The excellence of "The Discovery of Time" is unquestionable."--Martin Lebowitz, "The Kenyon Review"

What is the origin of the universe? What was there before the universe appeared? We are currently witnessing a second Copernican revolution: neither our Earth and Sun, nor our galaxy, nor even our universe, are the end of all things. Beyond our world, in an endless multiverse, are innumerable other universes, coming and going, like ours or different. Fourteen billion years ago, one of the many bubbles constantly appearing and vanishing in the multiverse exploded to form our universe. The energy liberated in the explosion provided the basis for all the matter our universe now contains. But how could this hot, primordial plasma eventually produce the complex structure of our present world? Does not order eventually always lead to disorder, to an increase of entropy? Modern cosmology is beginning to find out how it all came about and where it all might lead. Before Time Began tells that story.

"Helga Nowotny's exploration of the forms and meaning of time in contemporary life is panoramic without in any way partaking of the blandness of a survey. From the artificial time of the scientific laboratory to the distinctively modern yearning for one's own time, she regards every topic in this wide-ranging book from a fresh angle of vision, one which reveals unsuspected affinities between the bravest, newest worlds of global technology and the most ancient worlds of myth."
--Lorraine Daston, University of Chicago

This book represents a major contribution to the understanding of time, giving particular attention to time in relation to modernity. The development of industrialism, the author points out, was based upon a linear and abstract conception of time. Today we see that form of production, and the social institutions associated with it, supplanted by flexible specialization and just-in-time production systems. New information and communication technologies have made a fundamental impact here. But what does all this mean for temporal regimes? How can we understand the transformation of time and space involved in the bewildering variety of options on offer in a postmodern world?

The author provides an incisive analysis of the temporal implications of modern communication. She considers the implications of worldwide simultaneous experience, made possible by satellite technologies, and considers the reorganization of time involved in the continuous technological innovation that marks our era. In this puzzling universe of action, how does one achieve a 'time of one's own'? The discovery of a specific time perspective centred in the individual, she shows, expresses ayearning for forms of experience that are subversive of established institutional patterns.

This brilliant study, became a classic in Germany, will be of interest to students and professionals working in the areas of social theory, sociology, politics and anthropology.

A revolution in clock technology in England during the 1660s allowed people to measure time more accurately, attend to it more minutely, and possess it more privately than previously imaginable. In "Telling Time," Stuart Sherman argues that innovations in prose emerged simultaneously with this technological breakthrough, enabling authors to recount the new kind of time by which England was learning to live and work.
Through brilliant readings of Samuel Pepys's diary, Joseph Addison and Richard Steele's daily "Spectator," the travel writings of Samuel Johnson and James Boswell, and the novels of Daniel Defoe and Frances Burney, Sherman traces the development of a new way of counting time in prose--the diurnal structure of consecutively dated installments--within the cultural context of the daily institutions which gave it form and motion. "Telling Time" is not only a major accomplishment for seventeenth- and eighteenth-century literary studies, but it also makes important contributions to current discourse in cultural studies.

MAYAN STUDIES / NEW AGE"Reading this book is a powerful and electrifying experience. Each page offers penetrating insights that unravel the deepest mysteries of human history and the evolution of global consciousness." Michael E. Salla, Ph.D., Center for Global Peace The prophetic Mayan calendar is not keyed to the movement of planetary bodies. Instead, it functions as a metaphysical map of the evolution of consciousness and records how spiritual time flows, providing a new science of time. The calendar is associated with nine creation cycles, each of which represents one of nine levels of consciousness or Underworlds on the Mayan cosmic pyramid. Using empirical research, Carl Johan Calleman shows how this pyramidal structure of the development of consciousness can explain matters as disparate as the common origin of world religions and the modern complaint that time seems to be moving faster. Readers will learn that time is, in fact, speeding up as we transition from the materialistic Planetary Underworld that governs us today to a new and higher frequency of consciousness--the Galactic Underworld--in preparation for the final Universal level of conscious enlightenment. The Mayan Calendar and the Transformation of Consciousness reveals the Mayan calendar as a spiritual device that enables a greater understanding of the nature of conscious evolution throughout human history--and how it provides the concrete steps we can take to align ourselves with this growth toward enlightenment. CARL JOHAN CALLEMAN holds a Ph.D. in physical biology and has served as an expert on cancer for the World Health Organization. He began his studies on the Mayan calendar in 1979 and now lectures throughoutthe world. He is also author of Solving the Greatest Mystery of Our Time: The Mayan Calendar. He lives in Sweden.

Calendars and the celebration of feasts and holidays form an important part of religious and national movements and are sometimes the cause of schism. The Qumran community followed a solar calendar differing from the lunar calendar observed at the Temple in Jerusalem. This volume contains their texts relating to its calendar.

What is time? Did it have a beginning? What makes it appear to flow? Why is there a directionality or 'arrow' of time, and can it ever be reversed? It time travel possible? And might the universe be older than we thought?

The puzzles and paradoxes of time have dazzled the world's finest thinkers and throughout the ages philosophers have wrestled with the tensions between time and eternity, linear time and cyclicity, being and becoming. When Einstein formulated his theory of relativity early this century, it brought about a revolution in our understanding of time, yet also presented a new set of mysteries. Einstein's time can be warped, leading to bizarre possibilities such as black holes and time travel, while making nonsense of our perception of a 'now' and a division of time into past, present and future. In relation to quantum physics, time takes on even stranger aspects.

In this, his latest book, acclaimed physicist and writer Paul Davies confronts the tough questions about time, including the weird relationship between physical time and our psychological perception of it. He gives straightforward descriptions of topics such as the theory of relativity, time dilation and Hawking's 'imaginary time'. Davies concludes that despite decades of progress in unravelling the mysteries of time, the revolution begun by Einstein remains tantalizingly incomplete.

Richard Sorabji here takes time as his central theme, exploring fundamental questions about its nature: Is it real or an aspect of consciousness? Did it begin along with the universe? Can anything escape from it? Does it come in atomic chunks? In addressing these and myriad other issues, Sorabji engages in an illuminating discussion of early thought about time, ranging from Plato and Aristotle to Islamic, Christian, and Jewish medieval thinkers. Sorabji argues that the thought of these often neglected philosophers about the subject is, in many cases, more complete than that of their more recent counterparts.

Because they list all the public holidays and pagan festivals of the age, calendars provide unique insights into the culture and everyday life of ancient Rome. "The Codex-Calendar of 354" miraculously survived the Fall of Rome. Although it was subsequently lost, the copies made in the Renaissance remain invaluable documents of Roman society and religion in the years between Constantine's conversion and the fall of the Western Empire. In this richly illustrated book, Michele Renee Salzman establishes that the traditions of Roman art and literature were still very much alive in the mid-fourth century. Going beyond this analysis of precedents and genre, Salzman also studies "The Calendar of 354" as a reflection of the world that produced and used it. Her work reveals the continuing importance of pagan festivals and cults in the Christian era and highlights the rise of a respectable aristocratic Christianity that combined pagan and Christian practices. Salzman stresses the key role of the Christian emperors and imperial institutions in supporting pagan rituals. Such policies of accomodation and assimilation resulted in a gradual and relatively peaceful transformation of Rome from a pagan to a Christian capital.

An enjoyable and compelling ride through one of life's most fascinating enigmas
"What, then, is time? If no one ask of me, I know," St. Augustine of Hippo lamented. "But if I wish to explain to him who asks, I know not."
Who wouldn't sympathize with Augustine's dilemma? Time is at once intimately familiar and yet deeply mysterious. It is thoroughly intangible: We say it flows like a river -- yet when we try to examine that flow, the river seems reduced to a mirage. No wonder philosophers, poets, and scientists have grappled with the idea of time for centuries.
The enigma of time has also captivated science journalist Dan Falk, who sets off on an intellectual journey In Search of Time. The quest takes him from the ancient observatories of stone-age Ireland and England to the atomic clocks of the U.S. Naval Observatory; from the layers of geological "deep time" in an Arizona canyon to Albert Einstein's apartment in Switzerland. Along the way he talks to scientists and scholars from California to New York, from Toronto to Oxford. He speaks with anthropologists and historians about our deep desire to track time's cycles; he talks to psychologists and neuroscientists about the mysteries of memory; he quizzes astronomers about the beginning and end of time. Not to mention our latest theories about time travel -- and the paradoxes it seems to entail. We meet great minds from Aristotle to Kant, from Newton to Einstein -- and we hear from today's most profound thinkers: Roger Penrose, Paul Davies, Julian Barbour, David Deutsch, Lee Smolin, and many more.
As usual, Dan Falk's style combines exhaustive research with a lively, accessible, and often humorous style, making In Search of Time a delightful tour through a most curious dimension.

The ancient Romans changed more than the map of the world when they conquered so much of it; they altered the way historical time itself is marked and understood. In this brilliant, erudite, and exhilarating book Denis Feeney investigates time and its contours as described by the ancient Romans, first as Rome positioned itself in relation to Greece and then as it exerted its influence as a major world power. Feeney welcomes the reader into a world where time was movable and changeable and where simply ascertaining a date required a complex and often contentious cultural narrative. In a style that is lucid, fluent, and graceful, he investigates the pertinent systems, including the Roman calendar (which is still our calendar) and its near perfect method of capturing the progress of natural time; the annual rhythm of consular government; the plotting of sacred time onto sacred space; the forging of chronological links to the past; and, above all, the experience of empire, by which the Romans meshed the city state's concept of time with those of the foreigners they encountered to establish a new worldwide web of time. Because this web of time was Greek before the Romans transformed it, the book is also a remarkable study in the cross-cultural interaction between the Greek and Roman worlds.
Feeney's skillful deployment of specialist material is engaging and accessible and ranges from details of the time schemes used by Greeks and Romans to accommodate the Romans' unprecedented rise to world dominance to an edifying discussion of the fixed axis of B.C./A.D., or B.C.E./C.E., and the supposedly objective "dates" implied. He closely examines the most important of the ancient world's time divisions, that between myth and history, and concludes by demonstrating the impact of the reformed calendar on the way the Romans conceived of time's recurrence. Feeney's achievement is nothing less than the reconstruction of the Roman conception of time, which has the additional effect of transforming the way the way the reader inhabits and experiences time.

Days, months, and years were given to us by nature, but we invented the week for ourselves. There is nothing inevitable about a seven-day cycle, or about any other kind of week; it represents an arbitrary rhythm imposed on our activities, unrelated to anything in the natural order. But where the week exists--and there have been many cultures where it doesn't--it is so deeply embedded in our experience that we hardly ever question its rightness, or think of it as an artificial convention; for most of us it is a matter of 'second nature.'
