This book is about a side of Isaac Newton’s character that has not been examined – Isaac Newton as architect as demonstrated by his reconstruction of Solomon’s Temple. Although it is well known that Isaac Newton worked on the Temple, and this is mentioned in most of his biographies and in articles on the religious aspects of this work, however, there is no research on Newton’s architectural work. This book not only recreates Newton’s reconstruction of the Temple but it also considers how his work on the Temple interlinks with his other interests of science, chronology, prophecy and theology. In addition the book contains the first translation of Introduction to the Lexicon of the Prophets, Part two: About the appearance of the Jewish Temple commonly known by its call name Babson 0434. This work will appeal not only to scholars of science and architectural history but also to scholars of the seventeenth and eighteenth centuries’ history of ideas.
