This book is an introduction for those who are just approaching the ancient world of early christianity, and a guide full of insight for those who already have had a look of it. It is as important to philosophers as to historians, and to all those who are interested in the <<origins>> of Christianity and all the trouble it had before becoming one of the most expanded religions and cultures on our world. Moreover it makes an important step in linking the history of religion and of thought to the history of the human body. Mr. Brown wrote an excellent history book where any person seriuosly interested in the ancient world can find important information. Information, though, is not the only important thing in History, and in this book we can find much more: useful anecdotes are beautifully depicted in the very right place in order to make the thinking and the more practical need of our ancestors more undersandable to our western technological eyes. Also let me add, that this book is the result of some thirty years of reserch and extensive, but deep reeding of the writings and deed of the Fathers of Christianity. This book is, for us, an exceptional chance to read not only the translations of a very experienced translator of ancient literature but also his comments and crossed inquiries.
