A historical development of painting such as that referred to is of as great importance to scientific observation and exposition as it is to accurate study. The content of art as I have presented it, namely, the elaboration of its material, the distinct and fundamental changes in the mode of its conception, we find all this and more receives thus for the first time its concrete coherence in a sequence and under a classification which corresponds with the facts. It is therefore incumbent on us to glance at this process, if only by way of emphasis to what most immediately arrests attention.

In general the advance consists in this, that it originates in religious subjects conceived still in a typical way, with simple architectonic arrangement and unelaborated colour. After this, in an increasing degree of fusion with religious situations, we get actuality, vital beauty of form, individuality, depth of penetration, charm and witchery of colouring, until Art finally turns its attention to the world itself, makes itself master of Nature, the daily occurrence of ordinary life, or what is of significance in national history whether present or past, or portraiture and anything else down to the merest trifle and the least significant fact, and with an enthusiasm equal to that it devoted to the religious ideal, and pre-eminently in this sphere secures not merely the most consummate result of technical accomplishment, but also a treatment and execution which is most full of life and personality. This progress is followed in clearest outline if we take in succession the schools of Byzantine, Italian, Flemish, Dutch, and German painting, after noting the most prominent features of which briefly we shall finally indicate the transition to the art of music[330].

(a) In our review of Byzantine painting we may remark to start with that the practice of painting among the Greeks was to a definable degree always carried on; and examples of antique work contributed to the greater excellence of its results relatively to posture, draping, and other respects. On the other hand the touch of Nature and life wholly vanished from this art; in facial types it adhered strictly to tradition; in its figures and modes of expression it was conventional and rigid; in its general composition more or less architectonic. We find no trace of natural environment and a landscape background. The modelling, by means of light and shadow, brilliance and obscurity, and their fusion, no less than perspective and the art of lifelike grouping, either were not elaborated at all, or to a very slight extent. By reason of this strict adherence to a single acknowledged type independent artistic production had little room for its exercise. The art of painting and mosaic frequently degenerated into a mere craft, and became thereby lifeless and devoid of spirit, albeit such craftsmen, equally with the workers on antique vases, possessed excellent examples of previous work, which they could imitate so far as pose and the folding of drapery was concerned. A similar type of painting spread its sombre influence over the ravaged West and more particularly in Italy. Here, however, although in the first instance with beginnings of little strength, we are even at an early date conscious of an effort to break away from inflexible forms and modes of expression, and to face, at first, however, in a rough and ready way, a development of loftier aim. Of Byzantine pictures we may, on the contrary, affirm, as Herr von Rumohr[331] has maintained of Greek Madonnas and images of Christ that "it is obvious even in the most favoured examples, their origin was that of the mosaic, and artistic elaboration was rejected from the first." In other words[332] the Italians endeavoured even before the period of their independent art development in painting, and in contrast to the Byzantines to approximate to a more spiritual conception of Christian subjects. The writer above-named draws attention also as noteworthy support of his contention to the manner in which the later Greeks and Italians respectively represented Christ on crucifixes. According to this writer "the Greeks, to whom the sight of terrible bodily suffering was of common occurrence, conceived the Saviour suspended on the Cross with the entire weight of his body, the lower part of the body swollen and the slackened knees bent to the left, the bowed head contending with the pains of an awful death. Their subject was consequently in its essentials bodily suffering. The Italians, on the contrary, in their more ancient monuments, while we must not overlook the fact that the representation of the Virgin Mary with her Child no less than the Crucified is only of rare occurrence, were accustomed to depict the figure of the Saviour on the cross adopting, so it appears to us, the idea of the victory of the spiritual, not as in the former case the death of the body. And this unquestionably nobler conception asserts itself at an early date in the more favoured parts of Western Europe[333]." With this sketch I must here rest content.

(b) We have, however, secondly, another characteristic of art to consider in the earlier development of Italian painting. Apart from the religious content of the Old and New Testament and the biographies of martyrs and saints, it borrows its subjects in the main from Greek mythology, very seldom, that is, from the events of national history, or, if we except portraits, from the reality of contemporary life, and equally rarely, and only at a late stage and exceptionally, from natural landscape. Now that which it before all contributes to its conception and artistic elaboration of the subject-matter of religion is the vital reality of spiritual and corporeal existence, relatively to which at this stage all its forms are embodied and endowed with animation. For this vitality the essential principle on the spiritual side is that natural delightfulness, and on the corporeal side is that beauty which is consonant with physical form, a beauty which independently, as beautiful form, already displays innocence, buoyancy, maidenhood, natural grace of temperament, nobility, imagination, and a loving soul. If there is further added to a naturel of this type the exaltation and adornment of the soul in virtue of the ideal intimacy of religion and the spiritual characteristics of a profounder piety established as a vitalizing principle of soul-life in this essentially more admitted and inviolable province of spiritual redemption[334],—in such a case we have presented to us thereby an original harmony of form and its expression, which, wherever it is perfected, vividly reminds us in this sphere of romantic art and Christian art of the pure Ideal of art. No doubt also within a new accord of this type the inward life of the heart will be predominant; but this inward experience is a more happy, a purer heaven of the soul, the way of return to which form what is sensuous and finite, and the return to God, albeit the passage may be through a travail in the profounder anguish of repentance and death, is, however, less saturated with trouble and its insistency. And the reason of this is that the pain is concentrated in the sphere of soul, of idea, of faith, without making a descent into the region of passionate desire, intractable savagery, obstinate self-seeking and sin, and only arriving at the hardly won victory through smiting down such enemies of the blessed state. It is rather a transition of ideal permanence[335], a pain of the inward life, which feels itself as such suffering rather simply in virtue of its enthusiasm, a suffering of more abstract type, more spiritually abundant, which has as little need to brush away bodily anguish as we have to seek signs in the characterization of its bodily presence and physiognomy of obstinacy, uncouthness, crookedness, or the traits of superficial and mean natures, in which an obstinate conflict is first necessary, before such are meet to express real religious feeling[336] and piety. This more benign[337] intimacy of soul, this more original consonancy of exterior forms to ideal experience of this kind is what creates the charming clarity and the untroubled delight, which the genuinely beautiful works of Italian painting excite and supply. Just as we say of instrumental music that there is tone and melody in it, so, too, we find that the pure song of soul floats here in melodious fusion over the entire configuration and all its forms. And as in the music of the Italians and in the tones of their song, when the pure strains ring forth without a forced utterance, in every separate note and inflection of sound and melody, it is simply the delight of the voice itself which rings out; so, too, such an intimate personal enjoyment of the loving soul is the fundamental tone of their painting[338]. It is the same intimacy, clarity, and freedom which meet us again in the great Italian poets. To start with this artistic resonance of rhymes in their terzets, canzonets, sonnets, and stanzas, this accord, which is not merely satisfied to allay its thirst for reverberation in the one repetition, but repeats the echo three times and more, this is itself a euphony which streams forth on its own account and for the sake of its own enjoyment. And a like freedom is stamped upon the spiritual content. In Petrarch's sonnets, sestets, and canzonets it is not so much the actual possession of their subject, after which the heart yearns; it is not the consideration and emotion which are involved in the actual content of the poem as such, and which is therein necessarily expressed; rather it is the expression itself which constitutes the source of enjoyment. It is the self-delight of Love, which seeks its bliss in its own mourning, its laments, its descriptions, memories, and experience; a yearning, which is satisfied in itself as such, and with the image, the spirit of those it loves, is already in full possession of the soul, with which it longs to unite itself. Dante, too, when conducted by his master Virgil through hell and hell-fire, gazes at what is the culmination of horror, of awfulness; he is fearful, he often bursts into tears, but he strides on comforted and tranquil, without affright and anxiety, without the sullenness and embitterment which implies "these things should not be thus." Nay, even his damned in hell receive the blessedness of eternity. Io eterno duro is inscribed over the gates of hell. They are what they are, without repentance and longing; they do not speak of their sufferings; they are as immaterial to us as they are to them, for they endure for ever. Rather they are absorbed simply in their personal experience and actions, secure of themselves as rooted in the same interests, without lamentation and without yearning[339].

When we have grasped this trait of happy independence and freedom of the soul in love we shall understand the character of the greatest Italian painters. It is in this freedom that they are masters of the detail of expression, and situation. On the wings of this tranquillity of soul they can maintain their sovereignty over form, beauty, and colour. In their most defined presentation of reality and character, while remaining wholly on the earth and often only producing portraits, or appearing to produce such, what we have are pictures of another sun, another spring. They are roses which are equally heavenly blossoms. And, consequently, we find that in their beauty we do not have merely beauty of form, we do not have only the sensuous unity of soul impressed on sensuous corporeal shapes; we are confronted with this very trait of reconciled Love in every mode, feature, and individuality of character. It is the butterfly, the Psyche[340], which in the sunlight of its heaven, even hovers round stunted flowers[341]. It is only by virtue of this rich, free, and rounded beauty that they are able to unfold the ideals of the antique art's more recent perfection.

Italian art has, however, not immediately and from the first attained to such a point of perfection; it had in truth a long road to traverse before it arrived there. And yet, despite this, the purity and innocence of its piety, the largeness of the entire conception, the unassuming beauty of form, this intimate revelation of soul[342], are frequently and above all in the case of the old Italian masters most conspicuous where the technical elaboration is still wholly incomplete. In the previous century it was fashionable to depreciate these earlier masters, and place them on one side as clumsy, dull, and barren[343]. It is only in more recent times that they have been once more rescued from oblivion by savants and artists; but the wonder and imitation thus awakened has run off into the excess of a preference which tends to deny the advances of a further development in mode of conception and presentment, and can only lead astray in the opposite direction.

In drawing the reader's more close attention to the more important phases in the development of Italian art up to this period of its fullest perfection, I will only briefly emphasize the following points which immediately concern the characterization of the essential aspects of painting and its modes of expression.

(α) After the earliest stage of rawness and barbarism the Italians moved forward with a fresh impetus from that in the main craftsmanship type of art which was planted by the Byzantines. The compass of subjects depicted was, however, not extensive, and the distinctive features of the type were austerity, solemnity, and religious loftiness. But even at this stage—I am quoting the conclusions of Herr von Rumohr—who is generally recognized as an authority upon these earlier periods[344], Duccio, the Sienese, and Cimabue, the Florentine, endeavoured to assimilate the few remains of antique drawing, which was grounded on laws of perspective and anatomical precision, and so far as possible, to rejuvenate the same in their own genius. They "instinctively recognized the value of such drawings, but strove to soften the extreme insistence[345] of their ossification, comparing such insufficiently comprehended traits with the life such as we find it in fact or suggestion when face to face with their own productions[345]." Such are merely the first and mediating efforts of art to rise from the inflexibility of a type to lifelike and individual expression.

(β) The further step of advance consists in the complete severation from those previous Greek examples, in the full acceptance, relatively both to the entire conception and execution of what is distinctively human and individual, and along with this in the profounder suitability of human characters and forms which was gradually evolved to express the religious content thus to be expressed.

(αα) It is here before all we must draw attention to the great influence which Giotto and his pupils exercised. Giotto, along with the changes he effected in respect to modes of conception and composition, brought about a reform in the art of preparing colours. The later Greeks probably, such at least is the result of chemical analysis, made use of wax either as a medium of colour, or as a kind of varnish[346], and from this we get the yellow-green and obscure general tone, which is not sufficiently explained by the action of lamplight[347]. Giotto wholly dispensed with this glutinous medium of the Greek painters, and used instead, when preparing his colours[348], the clarified milk of young shoots, unripe figs, and other less oliginous limes[349], which Italian painters of the early Middle Ages had used, very likely even before they strenuously imitated the Byzantines[350]. A medium of this kind had no darkening effect on the colours, but left their luminosity and clarity unimpaired. Still more important was the reform effected by Giotto in Italian painting with respect to selection of subjects and their manner of presentment. Ghiberti himself praises Giotto for having abandoned the rude style of the Greeks, and without leaning in this direction to an excess having introduced the truth and grace of Nature. Boccaccio, too, says of him that Nature is unable to create anything that Giotto could not imitate to the point of deception[351]. In Byzantine pictures we can hardly detect a trace of natural appearance. It was Giotto, then, who concentrated his attention on what is present and actual, and compared the forms and effects which he undertook to exhibit with Life as it existed around him. And we may associate with this tendency the fact that during the times of Giotto not only do we find that the state of society was more free and intent on enjoyment, but that the veneration of several later saints took its rise then, saints whose lives more or less fell in that period[352]. It was such Giotto utilized particularly in emphasizing the truthful presentment of the subjects of his art; there was, in fact, thus the further demand suggested by the content itself that he should bring into prominence the natural features of the bodily presence and exhibit more defined characterization, action, passion, situation, pose, and movement. What we find, however, to a relative degree disappears from this attempt is that imposing religious seriousness which is the fundamental characteristic of the phase of art which it followed[353]. The things of the world receive a stage and a wider opportunity for expression; and this is illustrated by the way Giotto, under the influence of his age, found room for burlesque along with so much that was pathetic. In this connection Herr von Rumohr states rightly, "Under conditions of this description I am at a loss to understand how certain critics, who have exclusively insisted on this feature of Giotto's work, can so overestimate Giotto's tendency and performance by claiming it as the most sublime effort of modern art[354]." It is a great service of the above-named critic to have once more placed in a true light the point of view from which Giotto can be justly appreciated; he throughout makes us careful to see, that in this tendency of Giotto to humanize and towards realism he never really, as a rule, advances beyond a comparatively subordinate stage in the process.
