in this book, the author's purpose is to set out as simply and vividly as possible the exact grammatical workings of this architectural language. He is less concerned with its development in Greece and Rome than with its expansion and use in the centuries since the Renaissance. He explains the vigorous discipline of "the orders" and the scope of "rustication", the dramatic deviations of the Baroque and, in the last chapter, the relationship between the classical tradition and the "modern" architecture of today. The book is intended for anybody who cares for architecture but more specifically for students beginning a course in the history of architecture, to whom a guide to the classical rules will be an essential companion.
