Medieval Europe inherited from antiquity a rich and varied tradition of thought about the aetates hominum. Scholars divided human life into three, four, six, or seven ages, and so related it to larger orders of nature and history in which similar patterns were to be found. Thus, the seven ages correspond to and are governed by the seven planets. These ideas flowed through the Middle Ages in many channels: sermons and Bible commentaries, moral and political treatises, encyclopaedias and lexicons, medical and astrological handbooks, didactic and courtly poems, tapestries, wall-paintings, and stained-glass windows.Professor Burrow's account of this material, using mainly but not exclusively English medieval sources, includes a consideration of some of the ways in which such ideas of natural order entered into the medieval writer's assessment of human behaviour.The book ends by showing how medieval writers commonly recognize and endorse the natural processes by which ordinary folk pass from the joys and folly of youth to the sorrows and wisdom of old age.`I cannot believe that it will ever be superseded... it is the very strong but perfectly clear distillate of a great amount of labour and thought.' London Review of Books`short, pointed, witty, tightly packed, richly illustrated, inspired and illuminating.' Essays in Criticism`If we regret anything as we read this excellent book, we regret that it is not longer.' Christina von Nolcken, Review of English Studies`There is much to praise in the book; Burrow is learned and imaginative, writes lucidly, and... has illuminating things to say... J. A. Burrow is one of the best living critics of medieval English literature, and this book is a rich and informative literary history of an important topic.' Studies in the Age of Chaucer
