Cambridge has become a world famous university, with a reputation second to none for its scientific work, its discoveries and currently its hi-tec inventions. If you travel back beyond the mid 19th century, Cambridge was in no way reputed for its science, despite the fact that it spawned Isaac Newton, Charles Darwin and others; they were purely famous in their own right. For centuries Theology, the Queen of the Sciences, held sway. It was the major subject studied and all Fellows were obliged to enter holy orders until very recent times. Little surprise, therefore, that Cambridge became the cradle of the English Reformation. With influences from the nearby continent (including Erasmus and Luther) this is where so many of our leading Reformers developped their ideas for which they were prepared to die as martyrs. The mutually inclusive, as against exclusive relationship between Religion and Science is a major story in Cambridge, and it is that story which this guide book aims to tell.
