Our object in producing this book is to supply information about Chinese art that is at once authoritative and introductory. To many it may seem curious that no previous volume of the kind exists ; but to those who know the extreme difficulty of a detailed study of even one part of Chinese art, with its enormous periods and its close relationship to Eastern ideas, it may rather seem curious that anyone should attempt such a summary. We should not have given way to the desire to make such a book had we not known how valuable it would be if properly produced, and had we not felt that we had hit upon the right plan. -- Preface.
