APPENDIX 3 , A Comparison BETWEEN THIS EDITION AND THE TWO PENGUIN EDITIONS OF 1943 AND 1945 first edition of this book, published by Penguin Books in 1942, was by at least one-third shorter than this third edition. For readers familiar with the first or the enlarged second Penguin edition it may be useful to have a list of the chief additions. The most serious omission in the original text was Spain. I had decided, after much hesitation, to leave it out, partly for lack of space, and partly because I have never travelled in Spain. Then, however, Geoffrey Webb in his very generous review in The Architectural Review brought forward such incontrovertible reasons for giving Spain her due, even in the smallest of histories of architecture, that I changed my mind and said what little I could on the Visigothic-"Carolingian5* style, the Late Gothic of the I5th century, the Plateresque and the 18th-century Baroque. All these expres- sions" of the Spanish character in architecture may, from the European point of view, not be as central as events in France and Italy, but they are not more marginal than, say, the Elizabethan style in England or the Rococo in Germany. As for other additions, pages 24 to 26 have a little more on the schools of French Romanesque than there had been. From pages 56 to 66 nearly all is new, a somewhat more comprehensive analysis of Decorated and Perpendicular in England, the Late Gothic of the Friars and of Spain and the "Sondergotik" of Germany. Pages 103 to about 105 contain a far too brief account of Mannerism in Italian architecture; pages 142 to 145, anote on the development of staircases in the i6th and 17th centuries. On pages 155 to 157 some new matter, though not enough, will be found on the Elizabethan and Jacobean styles. Pages 188 to 190 are given to some hints on the landscape garden, one of the greatest English contributions to Western architecture, and one treated quite inadequately in the first edition. Finally, on pages 188 to 198 comment on the Classical and the early Gothic Revival is amplified, and some lines of appreciation inserted oxrthe genius of John Soane and Friedrich Gilly* So much for tie differences between the editions of 1943 and 1945. Now for this present edition still more minor gaps were filled in. There are a few lines new on pages i and 2 on Roman architecture, and a few on pages 4 and 5 on the origin of the Christian basilica and on Constantinian basilicas. On pages 7 and 8 a little more is said on Anglo-Saxon and . Merovingian churches, and on pages 10 and 11 a little more on Carolingian architecture, especially Centula. The treatment of the Romanesque style has scarcely been altered. Minor additions will be found regarding early tunnel-vaults (page 20), two-tower facades (page 24), the characteristics 227
