    With magisterial learning and the elan of a born storyteller, Pagels turns Satan's story into an audacious exploration of Christianity's shadow side, in which the gospel of love gives way to irrational hatreds that continue to haunt Christians and non-Christians alike.

    And since medieval Europe was the cradle of modern Western society, this work is vital for understanding our world and how it came into being.

    Originally a rebel leader, Josephus changed sides after he was captured to become a Rome-appointed negotiator, and so was uniquely placed to observe these turbulent events, from the siege of Jerusalem to the final heroic resistance and mass suicides at Masada. His account provides much of what we know about the history of the Jews under Roman rule, with vivid portraits of such key figures as the Emperor Vespasian and Herod the Great. Often self-justifying and divided in its loyalties, The Jewish War nevertheless remains one of the most immediate accounts of war, its heroism and its horrors, ever written.

    Yet it was, according to Professor Harl, "without a doubt the greatest state in Christendom through much of the Middle Ages," and well worth our attention as a way to widen our perspective on everything from the decline of imperial Rome to the rise of the Renaissance.In a series of 24 tellingly detailed lectures, you'll learn how the Greek-speaking empire of Byzantium, or East Rome, occupied a crucial place in both time and space that began with Constantine the Great and endured for more than a millennium - a crucible where peoples, cultures, and ideas met and melded to create a world at once Eastern and Western, Greek and Latin, classical and Christian. And you'll be dazzled by the achievements of Byzantium's emperors, patriarchs, priests, monks, artists, architects, scholars, soldiers, and officialsPreserving and extending the literary, intellectual, and aesthetic legacy of Classical and Hellenistic GreeceCarrying forward path-breaking Roman accomplishments in law, politics, engineering, architecture, urban design, and military affairsDeepening Christian thought while spreading the faith to Russia and the rest of what would become the Orthodox worldDeveloping Christian monastic institutionsShielding a comparatively weak and politically fragmented western Europe from the full force of eastern nomadic and Islamic invasionsFusing classical, Christian, and eastern influencesHelping to shape the course of the Humanist revival and the Renaissance

    But the crusaders never made it to the Holy Land. Steered forward by the shrewd Venetian doge, they descended instead on Constantinople, wreaking terrible devastation. The crusaders spared no one: They raped and massacred thousands, plundered churches, and torched the lavish city. By 1204, one of the great civilizations of history had been shattered. Here, on the eight hundredth anniversary of the sack, is the extraordinary story of this epic catastrophe, told for the first time outside of academia by Jonathan Phillips, a leading expert on the crusades. Knights and commoners, monastic chroniclers, courtly troubadours, survivors of the carnage, and even Pope Innocent III left vivid accounts detailing the events of those two fateful years. Using their remarkable letters, chronicles, and speeches, Phillips traces the way in which any region steeped in religious fanaticism, in this case Christian Europe, might succumb to holy war.

    “Fascinating, brave & sometimes infuriating” (Time), this dark history is more than a chronicle of religion. It's the central tragedy of Western civilization, its fault lines reaching deep into our culture to create “a deeply felt work” (San Francisco Chronicle) as Carroll wrangles with centuries of strife & tragedy to reach a courageous & affecting reckoning with difficult truths.

    Since then, a number of historians have built on Jonathan Riley-Smith's original conclusions. Now in its fourth edition, this classic starting point for the study of the crusading movement has been updated to take into account the latest developments in the field.What Were the Crusades?   elucidates key ideas and institutions which have been neglected in the past   demonstrates, through the analysis of European campaigns, that the movement was not confined to expeditions launched to recover the Holy Land - or to defend the Christian presence there - and shows that it continued, in one form or another, into the eighteenth century and perhaps beyond   draws attention to the increasing interest of historians in the motivation of crusaders   now includes material on a child crusader and concludes with a short discussion of the current effects of aggressive Pan-Islamism   features a new map illustrating the different theatres of war       Original in its conception, this essential guide is a contribution of major importance to crusading scholarship. In its clear and concise treatment of the issues, it remains an unequalled introduction to the subject for students and general readers alike.

    Eamon Duffy shows that late medieval Catholicism was neither decadent nor decayed, but was a strong and vigorous tradition, and that the Reformation represented a violent rupture from a popular and theologically respectable religious system. For this edition, Duffy has written a new Preface reflecting on recent developments in our understanding of the period.From reviews of the first edition:“A magnificent scholarly achievement [and] a compelling read.”—Patricia Morrison, Financial Times“Deeply imaginative, movingly written, and splendidly illustrated. . . . Duffy’s analysis . . . carries conviction.”—Maurice Keen, New York Review of Books“This book will afford enjoyment and enlightenment to layman and specialist alike.”—Peter Heath, Times Literary Supplement“[An] astonishing and magnificent piece of work.”—Edward T. Oakes, Commonweal

    And if Constantine the emperor were not problem enough, we all know that Constantinianism has been very bad for the church. Or do we know these things? Peter Leithart weighs these claims and finds them wanting. And what's more, in focusing on these historical mirages we have failed to notice the true significance of Constantine and Rome baptized. For beneath the surface of this contested story there emerges a deeper narrative of the end of Roman sacrifice--a tectonic shift in the political theology of an empire--and with far-reaching implications. In this probing and informative book Peter Leithart examines the real Constantine, weighs the charges against Constantinianism, and sets the terms for a new conversation about this pivotal emperor and the Christendom that emerged.

    AD 539-594) is a fascinating exploration of the events that shaped sixth-century France. This volume contains all ten books from the work, the last seven of which provide an in-depth description of Gregory's own era, in which he played an important role as Bishop of Tours. With skill and eloquence, Gregory brings the age vividly to life, as he relates the exploits of missionaries, martyrs, kings and queens - including the quarrelling sons of Lothar I, and the ruthless Queen Fredegund, third wife of Chilperic. Portraying an age of staggering cruelty and rapid change, this is a powerful depiction of the turbulent progression of faith at a time of political and social chaos.

    It begins with Julius Caesar's invasion in the first century BC and goes on to tell of the kings and bishops, monks and nuns who helped to develop government and convert the people to Christianity during these crucial formative years.

    It was an article of faith that a saintly emperor, divinely appointed, had founded Constantinople and that the city was as holy as Rome or Jerusalem. The Byzantine emperors assiduously promoted the notion of a spiritual aura around the city. Thus, in 917, the emperor's regent wrote to the khan of the Bulgars warning him not to attack Constantinople. He did not threaten the khan with military force, but with the Virgin Mary who, as 'commander in chief of the city', would not take kindly to any assault. It was with legends and beliefs like this that the emperors bolstered their power and wealth, and the myth was central to the success of Constantinople and its empire for over a thousand years. Although this is hardly the first history of Byzantium to be published, Jonathan Harris differentiates himself by offering keen insight into the spiritual and mythic dimensions of Constantinople, key elements of the city's history that have neglected until now. Constantinople: Capital of Byzantine is the first history of this great empire to properly examine the intriguing interaction between the spiritual and the political, the mythical and the actual. The result is an accessible and engaging account of a colorful and vital time in human history, and a long overdue look at an awe-inspiring city in its heyday.
