On several grounds it is possible to make a more speedy and extensive application of artistic reform to our interior decoration than to our external architecture. One of these grounds is that most of our ugly buildings must stand; we cannot afford to pull them down. But every year we are decorating interiors afresh, and people of modest means may benefit by the introduction of beautiful designs into stucco ornaments, paper-hangings, draperies, and carpets. Fine taste in the decoration of interiors is a benefit that spreads from the palace to the clerk’s house with one parlor. All honor, then, to the architect who has zealously vindicated the claim of internal ornamentation to be a part of the architect’s function, and has labored to rescue that form of art which is most closely connected with the sanctities and pleasures of our hearths from the hands of uncultured tradesmen. All the nation ought at present to know that this effort is peculiarly associated with the name of Mr. Owen Jones; and those who are most disposed to dispute with the architect about his coloring must at least recognize the high artistic principle which has directed his attention to colored ornamentation as a proper branch of architecture. One monument of his effort in this way is his “Grammar of Ornament,” of which a new and cheaper edition has just been issued. The one point in which it differs from the original and more expensive edition, viz., the reduction in the size of the pages (the amount of matter and number of plates are unaltered), is really an advantage; it is now a very manageable folio, and when the reader is in a lounging mood may be held easily on the knees. It is a magnificent book; and those who know no more of it than the title should be told that they will find in it a pictorial history of ornamental design, from its rudimentary condition as seen in the productions of savage tribes, through all the other great types of art—the Egyptian, Assyrian, ancient Persian, Greek, Roman, Byzantine, Arabian, Moresque, Mohammedan-Persian, Indian, Celtic, Mediæval, Renaissance, Elizabethan, and Italian. The letter-press consists, first, of an introductory statement of fundamental principles of ornamentation—principles, says the author, which will be found to have been obeyed more or less instinctively by all nations in proportion as their art has been a genuine product of the national genius; and, secondly, of brief historical essays, some of them contributed by other eminent artists, presenting a commentary on each characteristic series of illustrations, with the useful appendage of bibliographical lists.
