This book was begun six years ago, in 1842. It has since been often laid aside, and again resumed. In this long interval, many useful and delightful works have been written on the same subject, but still the particular ground I had chosen remained unoccupied; and, amid many difficulties, and the consciousness of many deficiencies, I was encouraged to proceed, partly by the pleasure I took in a task so congenial—partly by the conviction that such a work has long been wanted by those who are not contented with a mere manual of reference, or a mere catalogue of names. This book is intended not only to be consulted, but to be read—if it be found worth reading. It has been written for those who are, like myself, unlearned; yet less, certainly, with the idea of instructing, than from a wish to share with others those pleasurable associations, those ever new and ever various aspects of character and sentiment, as exhibited in Art, which have been a source of such vivid enjoyment to myself. This is the utmost limit of my ambition; and, knowing that I cannot escape criticism, I am at least anxious that there should be no mistake as to purpose and intention. I hope it will be clearly understood that I have taken throughout the æsthetic and not the religious view of those productions of Art which, in as far as they are informed with a true and earnest feeling, and steeped in that beauty which emanates from genius inspired by faith, may cease to be Religion, but cannot cease to be Poetry; and as poetry only I have considered them. The difficulty of selection and compression has been the greatest of all my difficulties; there is not a chapter in this book which might not have been more easily extended to a volume than compressed into a few pages. Every reader, however, who is interested in the subject, may supply the omissions, follow out the suggestions, and enjoy the pleasure of discovering new exceptions, new analogies, for himself. With regard to the arrangement, I am afraid it will be found liable to objections; but it is the best that, after long consideration and many changes, I could fix upon. It is not formal, nor technical, like that of a catalogue or a calendar, but intended to lead the fancy naturally from subject to subject as one opened upon another, with just sufficient order to keep the mind unperplexed and the attention unfatigued amid a great diversity of objects, scenes, stories, and characters.
