From the Preface.
THE First Part of this work, treated of the Five Roman Orders, and presented a simple method of drawing them, in accordance with the proportions determined by Vignola. Chapters were added on the Intercolumniation and Superposition of Columns, and on Parapets, Balustrades, String-Courses, Pediments, and Attics.
In the Preface, I said that the employment of these Elements in the composition of Doors and Windows, Wall Surfaces, Staircases, Towers and Spires, Arches and Arcades, Vaults and Domes, might someday be made the subject of a separate treatise which would be the natural sequel of the first. The present publication fulfils this promise, except that Towers and Spires are not among the topics taken up. It contains also, under the heading of Wall Treatment, a discussion of Coupled Pilasters, and of the treatment of Pilasters and of Cornices on external and internal angles, which might perhaps just as well have been put into the other volume.
Of the Nineteen Plates placed at the end of the book, three are taken from Sir William Chambers' Civil Architecture, though the figuring of the orders is simplified, in accordance with the system set forth in Part I. One Plate is taken from Gruner's Fresco Painting in Italy, one from the Comte de Clarac's Louvre and Tuileries, and one from Letarouilly's Edifices de Rome Modeme. Of the hundred and three illustrations inserted in the Text, half a dozen, and an equal number of the figures in some of the Plates, have been copied or traced from various works of reference. The remainder of the Plates and Figures have been drawn out from sketches made under my direction. For the sympathetic care and skill with which this work has been done I am much indebted to the young men who have divided the work among them, and am under special obligations to Mr. G. L. Smith, Mr. H. V. Skene, Mr. F. M. Riley, and Mr. Joseph Wilson, for serviceable criticisms and suggestions.
