Book excerpt: "In this book Liane Lefaivre and Alexander Tzonis bring together 140 documents spanning a period from the year 1000 to the end of the eighteenth century. They argue that Modern Architectural thinking was created during this period, a wholly new forma mentis for conceiving buildings, landscapes, and cities. The material includes, in addition to the more predictable texts, key extracts from architectural treatises, handbooks, and textbooks, material from letters, articles from the press of the times, scientific memoirs, maxims, poems, plays, and novels. Their authors are equally varied architects, patrons, politicians, artists, poets, scientists, priests, philosophers, and journalists. Some describe and systematize, some argue and criticize, and a large number are eager to present new findings and new ways to construe and construct the world.".
