less for an elaborate finish, united with energetic freshness, which seem to show that time has been much concerned in its production, and has had no power over its fate.

104. We do not say that the total force of the material is exhibited in this picture, or even that it in any degree possesses the lusciousness and fullness which are among the chief charms of oil-painting; but that upon the whole it would be selected as uniting imperishable firmness with exquisite delicacy; as approaching more unaffectedly and more closely than any other work to the simple truths of natural color and space; and as exhibiting, even in its quaint and minute treatment, conquest over many of the difficulties which the boldest practice of art involves.

This picture, bearing the inscription "Johannes Van Eyck (fuit?) hic, 1434," is probably the portrait, certainly the work, of one of those brothers to whose ingenuity the first invention of the art of oil-painting has been long ascribed. The volume before us is occupied chiefly in determining the real extent of the improvements they introduced, in examining the processes they employed, and in tracing the modifications of those processes adopted by later Flemings, especially Rubens, Rembrandt, and Vandyck. Incidental notices of the Italian system occur, so far as, in its earlier stages, it corresponded with that of the north; but the consideration of its separate character is reserved for a following volume, and though we shall expect with interest this concluding portion of the treatise, we believe that, in the present condition of the English school, the choice of the methods of Van Eyck, Bellini, or Rubens, is as much as we could modestly ask or prudently desire.

105. It would have been strange indeed if a technical perfection like that of the picture above described (equally characteristic of all the works of those brothers), had been at once reached by the first inventors of the art So far was this from being the case, and so distinct is the evidence of the practice of oil-painting in antecedent periods, that of late years the discoveries of the Van Eycks have not unfrequently

been treated as entirely fabulous; and Raspe, in particular, rests their claims to gratitude on the contingent introduction of amber-varnish and poppy-oil:-" Such perhaps," he says,

might have been the misrepresented discovery of the Van Eycks." That tradition, however, for which the great painters of Italy, and their sufficiently vain historian, had so much respect as never to put forward any claim in opposition to it, is not to be clouded by incautious suspicion. Mr. Eastlake has approached it with more reverence, stripped it of its exaggeration, and shown the foundations for it in the fact that the Van Eycks, though they did not create the art, yet were the first to enable it for its function; that having found it in servile office and with dormant power-laid like the dead Adonis on his lettuce-bed-they gave it vitality and dominion. And fortunate it is for those who look for another such reanimation, that the method of the Van Eycks was not altogether their own discovery. Had it been so, that method might still have remained a subject of conjecture; but after being put in possession of the principles commonly acknowledged before their time, it is comparatively easy to trace the direction of their inquiry and the nature of their improvements.

106. With respect to remote periods of antiquity, we believe that the use of a hydrofuge oil-varnish for the protection of works in tempera, the only fact insisted upon by Mr. Eastlake, is also the only one which the labor of innumerable ingenious writers has established: nor up to the beginning of the twelfth century is there proof of any practice of painting except in tempera, encaustic (wax applied by the aid of heat), and fresco. Subsequent to that period, notices of works executed in solid color mixed with oil are frequent, but all that can be proved respecting earlier times is a gradually increasing acquaintance with the different kinds of oil and the modes of their adaptation to artistical uses.

Several drying oils are mentioned by the writers of the first three centuries of the Christian era-walnut by Pliny and Galen, walnut, poppy, and castor-oil (afterwards used

by the painters of the twelfth century as a varnish) by Dioscorides yet these notices occur only with reference to medicinal or culinary purposes. But at length a drying oil is mentioned in connection with works of art by Aetius, a medical writer of the fifth century. His words are:

"Walnut oil is prepared like that of almonds, either by pounding or pressing the nuts, or by throwing them, after they have been bruised, into boiling water. The (medicinal) uses are the same: but it has a use besides these, being employed by gilders or encaustic painters; for it dries, and preserves gildings and encaustic paintings for a long time.”

"It is therefore clear," says Mr. Eastlake, " that an oil varnish, composed either of in-pissated nut oil, or of nut oil combined with a dissolved resin, was employed on gilt surfaces and pictures, with a view to preserve them, at least as early as the fifth century. It may be added that a writer who could then state, as if from his own experience, that such varnishes had the effect of preserving works for a long time,' can hardly be understood to speak of a new invention.” -P. 22.

Linseed-oil is also mentioned by Aetius, though still for medicinal uses only; but a varnish, composed of linseed oil mixed with a variety of resins, is described in a manuscript at Lucca, belonging probably to the eighth century:

"The age of Charlemagne was an era in the arts; and the addition of linseed-oil to the materials of the varnisher and decorator may on the above evidence be assigned to it. From this time, and during many ages, the linseed-oil varnish, though composed of simpler materials (such as sandarac and mastic resin boiled in the oil), alone appears in the recipes hitherto brought to light."- Ib., p. 24.

107. The modes of bleaching and thickening oil in the sun, as well as the siccative power of metallic oxides, were

known to the classical writers, and evidence exists of the careful study of Galen, Dioscorides, and others by the painters of the twelfth and thirteenth centuries: the loss (recorded by Vasari) of Antonio Veneziano to the arts, "per che studio in Dioscoride le cose dell' erbe," is a remarkable instance of its less fortunate results. Still, the immixture of solid color with the oil, which had been commonly used as a varnish for tempera paintings and gilt surfaces, was hitherto unsuggested; and no distinct notice seems to occur of the first occasion of this important step, though in the twelfth century, as above stated, the process is described as frequent both in Italy and England. Mr. Eastlake's instances have been selected, for the most part, from four treatises, two of which, though in an imperfect form, have long been known to the public; the third, translated by Mrs. Merrifield, is in course of publication; the fourth, "Tractatus de Coloribus illuminatorum," is of less importance.

Respecting the dates of the first two, those of Eraclius and Theophilus, some difference of opinion exists between Mr. Eastlake and their respective editors. The former MS. was published by Raspe,* who inclines to the opinion of its having been written soon after the time of St. Isidore of Seville, probably therefore in the eighth century, but insists only on its being prior to the thirteenth. That of Theophilus, published first by M. Charles de l'Escalopier, and lately from a more perfect MS. by Mr. Hendrie, is ascribed by its English editor (who places Eraclius in the tenth) to the early half of the eleventh century. Mr. Hendrie maintains his opinion with much analytical ingenuity, and we are disposed to think that Mr. Eastlake attaches too much importance to the absence of reference to oil-painting in the Mappæ Clavicula (a MS. of the twelfth century), in placing Theophilus a century and a half later on that ground alone. The question is one of some importance in an antiquarian point of view, but the general reader will perhaps be satisfied with the conclusion that in MSS. which cannot possibly be later than the * "A Critical Essay on Oil-Painting," London, 1781.

close of the twelfth century, references to oil-painting are clear and frequent.

108. Nothing is known of the personality of either Eraclius or Theophilus, but what may be collected from their works; amounting, in the first case, to the facts of the author's "language being barbarous, his credulity exceptionable, and his knowledge superficial," together with his written description as "vir sapientissimus;" while all that is positively known of Theophilus is that he was a monk, and that The ophilus was not his real name. The character, however, of which the assumed name is truly expressive, deserves from us no unrespectful attention; we shall best possess our readers of it by laying before them one or two passages from the preface. We shall make some use of Mr. Hendric's translation; it is evidently the work of a tasteful man, and in most cases renders the feeling of the original faithfully; but the Latin, monkish though it be, deserved a more accurate following, and many of Mr. Hendrie's deviations bear traces of unsound scholarship. An awkward instance occurs in the first paragraph:

"Theophilus, humilis presbyter, servus servorum Dei, indignus nomine et professione monachi, omnibus mentis desidiam animique vagationem utili manuum occupatione, et delectabili novitatum meditatione declinare et calcare volen tibus, retributionem cœlestis præmii!”

** I, Theophilus, an humble priest, servant of the servants of God, unworthy of the name and profession of a monk, to all wishing to overcome and avoid sloth of the mind or wandering of the soul, by useful manual occupation and the delightful contemplation of novelties, send a recompense of heavenly price."-Theophilus, p. 1.

Præmium is not "price," nor is the verb understood before retributionem “send.” Mr. Hendrie seems even less fanaliar with Scriptural than with monkish language, or in this and several other cases he would have recognized the adoption
