With regard to the actual knowledge of Latin literature possessed in the Middle Ages, it may be said in brief that Virgil was continually studied, and that a certain familiarity with Ovid, Lucan, Horace, Juvenal, and Statius was never lost. Among the prose-writers, portions of Cicero were used in education; but the compilations of Boethius, Priscian, Donatus, and Cassiodorus were more widely used. In the twelfth century the study of Roman law was revived, and the scholastic habit of thought found scope for subtlety in the discussion of cases and composition of glosses. The general knowledge and intellectual sympathy required for comprehension of the genuine classics were, however, wanting; and thus it happened that their place was taken by epitomes and abstracts, and by the formal digests of the Western Empire in its decadence. This lifeless literature was better suited to the meagre intellectual conditions of the Middle Ages than the masterpieces of the Augustan and Silver periods.

Of Greek there was absolutely no tradition left.[17] When the names of Greek poets or philosophers are cited by mediæval authors, it is at second hand from Latin sources; and the Aristotelian logic of the schoolmen came through Latin translations made by Jews from Arabian MSS. Occasionally it might happen that a Western scholar acquired Greek at Constantinople or in the south of Italy, where it was spoken; but this did not imply Hellenic culture, nor did such knowledge form a part and parcel of his erudition. Greek was hardly less lost to Europe then than Sanskrit in the first half of the eighteenth century.

The meagreness of mediæval learning was, however, a less serious obstacle to culture than the habit of mind, partly engendered by Christianity and partly idiosyncratic to the new races, which prevented students from appreciating the true spirit of the classics. While mysticism and allegory ruled supreme, the clearly-defined humanity of the Greeks and Romans could not fail to be misapprehended. The little that was known of them reached students through a hazy and distorting medium. Poems like Virgil's fourth Eclogue were prized for what the author had not meant when he was writing them; while his real interests were utterly neglected. Against this mental misconception, this original obliquity of vision, this radical lie in the intellect, the restorers of learning had to fight at least as energetically as against brute ignorance and dulness. It was not enough to multiply books and to discover codices; they had to teach men how to read them, to explain their inspiration, to defend them against prejudice, to protect them from false methods of interpretation. To purge the mind of fancy and fable, to prove that poetry apart from its supposed prophetic meaning was delightful for its own sake, and that the history of the antique nations, in spite of Paganism, could be used for profit and instruction, was the first step to be taken by these pioneers of modern culture. They had, in short, to create a new mental sensibility by establishing the truth that pure literature directly contributes to the dignity and happiness of human beings. The achievement of this revolution in thought was the great performance of the Italians in the fourteenth and fifteenth centuries.

During the dark ages Italy had in no sense enjoyed superiority of culture over the rest of Europe. On the contrary, the first abortive attempt at a revival of learning was due to Charlemagne at Aix, the second to the Emperor Frederick in Apulia and Sicily; and while the Romance nations had lost the classical tradition, it was still to some extent preserved by the Moslem dynasties. The more we study the history of mediæval learning, the more we recognise the debt of civilised humanity to the Arabs for their conservation and transmission of Greek thought in altered form to Europe. Yet, though the Italians came comparatively late into the field, their action was decisive. Neither Charlemagne nor Frederick, neither the philosophy of the Arabian sages nor the precocious literature of Provence, succeeded in effecting for the education of the modern intellect that which Dante and Petrarch performed—the one by the production of a monumental work of art in poetry, the other by the communication of a new enthusiasm for antiquity to students.

Dante does not belong in any strict sense to the history of the Revival of Learning. The 'Divine Comedy' closes the Middle Ages and preserves their spirit. It stands before the vestibule of modern literature like a solitary mountain at the entrance of a country rich in all varieties of landscape. In order to become acquainted with its grandeur, we must leave the fields and forests that we know, ascend the heights, and use ourselves to an austerer climate. In spite of this isolation, Dante's influence was powerful upon succeeding generations. The modern mind first found in him its scope, and recognised its freedom; first dared and did what placed it on a level with antiquity in art. Many ideas, moreover, destined to play an important part in the coming age, received from him their germinal expression. It may thus be truly said that Dante initiated the movement of the modern intellect in its entirety, though he did not lead the Revival considered as a separate moment in this evolution. That service was reserved for Petrarch.

There are spots upon the central watershed of Europe where, in the stillness of a summer afternoon, the traveller may listen to the murmurs of two streams—the one hurrying down to form the Rhine, the other to contribute to the Danube or the Po. Born within hearing of each other's voices, and nourished by the self-same clouds that rest upon the crags around them, they are henceforth destined to an ever-widening separation. While the one sweeps onward to the Northern seas, the other will reach the shores of Italy or Greece and mingle with the Mediterranean. To these two streamlets we might compare Dante and Petrarch, both of whom sprang from Florence, both of whom were nurtured in the learning of the schools and in the lore of chivalrous love. Yet how different was their mission! Petrarch marks the rising of that great river of intellectual energy which flowed southward to recover the culture of the ancient world. The current of Dante's genius took the contrary direction. Borne upon its mighty flood, we visit the lands and cities of the Middle Ages, floating toward infinities divined and made the heritage of human nature by the mediæval spirit.

In speaking of Petrarch here, it is necessary to concentrate attention upon his claims to be considered as the apostle of scholarship, the inaugurator of the humanistic impulse of the fifteenth century. We have nothing to do with his Italian poetry. The Rime dedicated to Madonna Laura have eclipsed the fame of the Latin epic, philosophical discourses, epistles, orations, invectives, and dissertations, which made Petrarch the Voltaire of his own age, and on which he thought his immortality would rest. Yet it is with these latter products of his genius, not with the Canzoniere, that we are now concerned; nor can it be too emphatically asserted that his originality was even more eminently displayed in the revelation of humanism to the modern world than in the verses that impressed their character upon Italian literature. To have foreseen a whole new phase of European culture, to have interpreted its spirit, and determined by his own activity the course it should pursue, is in truth a higher title to fame than the composition of even the most perfect sonnets. The artist, however, has this advantage over the pioneer of intellectual progress, that his delicate creations are indestructible, and that his work cannot be merged in that of a continuator. Therefore Petrarch lives and will live in the memory of millions as the poet of Laura, while only students know how much the world owes to his humanistic ardour.

As I cannot dispense with the word Humanism in this portion of my work, it may be well to fix the sense I shall attach to it.[18] The essence of humanism consisted in a new and vital perception of the dignity of man as a rational being apart from theological determinations, and in the further perception that classic literature alone displayed human nature in the plenitude of intellectual and moral freedom. It was partly a reaction against ecclesiastical despotism, partly an attempt to find the point of unity for all that had been thought and done by man, within the mind restored to consciousness of its own sovereign faculty. Hence the single-hearted devotion to the literature of Greece and Rome that marks the whole Renaissance era. Hence the watchword of that age, the Litteræ Humaniores. Hence the passion for antiquity, possessing thoughtful men, and substituting a new authority for the traditions of the Church. Hence the so-called Paganism of centuries bent upon absorbing and assimilating a spirit no less life-giving from their point of view than Christianity itself. Hence the persistent effort of philosophers to find the meeting-point of two divergent inspirations. Hence, too, the ultimate antagonism between the humanists, or professors of the new wisdom, and those uncompromising Christians who, like S. Paul, preferred to remain fools for Christ's sake.

Humanism in this, the widest, sense of the word was possessed by Petrarch intuitively. It belonged to his nature as much as music to Mozart; so that he seemed sent into the world to raise, by the pure exercise of innate faculties, a standard for succeeding workers. Physically and æsthetically, by the fineness of his ear for verbal harmonies, and by the exquisiteness of his sensibilities, he was fitted to divine what it took centuries to verify. While still a boy, long before he could grasp the meaning of classical Latin, he used to read the prose of Cicero aloud, delighting in the sonorous cadence and balanced periods of the master's style.[19] Nor were the moral qualities of industry and perseverance, needed to supplement these natural gifts, defective. In his maturity he spared no pains to collect the manuscripts of Cicero, sometimes transcribing them with his own hand, sometimes employing copyists, sending and journeying to distant parts of Europe where he heard a fragment of his favourite author might be found.[20] His greatest literary disappointment was the loss of a treatise by Cicero on Glory, a theme exceedingly significant for the Renaissance, which he lent to his tutor Convennevole, and which the old man pawned.[21] Though he could not read Greek, he welcomed with profoundest reverence the codices of Homer and Plato sent to him from Constantinople, and exhorted Boccaccio to dedicate his genius to the translation of the sovran poet into Latin.[22] In this susceptibility to the melodies of rhetorical prose, in this special cult of Cicero, in the passion for collecting manuscripts, and in the intuition that the future of scholarship depended upon the resuscitation of Greek studies, Petrarch initiated the four most important momenta of the classical Renaissance. He, again, was the first to understand the value of public libraries;[23] the first to accumulate coins and inscriptions, as the sources of accurate historical information; the first to preach the duty of preserving ancient monuments. It would seem as though, by the instinct of genius, he foresaw the future for at least three centuries, and comprehended the highest uses whereof scholarship is capable.

So far the outside only of Petrarch's instinct for humanism has been touched. How fully he possessed its large and liberal spirit is shown by the untiring war he carried on against formalism, tradition, pedantry, and superstition. Whatever might impede the free play of the intellect aroused his bitterest hatred. Against the narrow views of scholastic theologians, against the futile preoccupations of the Middle-Age materialists, against the lawyers and physicians and astrologers in vogue, he declared inexorable hostility.[24] These men, by their puerilities and falsities, obstructed the natural action of the mind; therefore Petrarch attacked them. At the same time he recognised the liberators of the reason by a kind of tact. Though he could not interpret the sixteen dialogues of Plato he possessed in Greek, he perceived intuitively that Plato, as opposed to Aristotle, would become the saint of liberal philosophy, surveyed by him as in a Pisgah-view. His enthusiasm for Cicero and Virgil was twofold; in both respects he proved how capable he was of moulding the taste and directing the mental force of his successors. As an artist, he discerned in their style the harmonies of sound and the proprieties of diction, whereby Latin might once again become the language of fine thoughts and delicate emotions. As a champion of intellectual independence, he saw that, studying their large discourse of all things which the reason and imagination can appropriate, the thinkers of the modern age might shake off scholastic fetters, and enter into the inheritance of spiritual freedom. Poetry and rhetoric he regarded not merely as the fine arts of literature, but as two chief instruments whereby the man of genius arrives at self-expression, perpetuates the qualities of his own soul, and impresses his character upon the age. Since this realisation of the individual in a high and puissant work of art appeared to him the noblest aim of man on earth, it followed that the inspired speech of the poet and the eloquence of the orator became for Petrarch the summit of ambition, the two-peaked Parnassus he struggled through his lifetime to ascend.[25] The ideal was literary; but literature implied for Petrarch more than words and phrases. It was not enough to make melodious verse, or to move an audience with well-sounding periods. The hexameters of the epic and the paragraphs of the oration had to contain solid thought, to be the genuine outcome of the poet's or the rhetorician's soul. The writer was bound to be a preacher, to discover truth, and make the truths he found agreeable to the world.[26] His life, moreover, ought to be in perfect harmony with all he sought to teach.[27] Upon the purity of his enthusiasm, the sincerity of his inspiration, depended the future well-being of the world for which he laboured.[28] Thus for this one man at least the art of letters was a priesthood; and the earnestness of his vocation made him fit to be the master of succeeding ages. It is not easy for us to appreciate the boldness and sincerity of these conceptions. Many of them, since the days of Petrarch, have been overstrained and made ridiculous by false pretensions. Besides, the whole point of view has been appropriated; and men invariably undervalue what they feel they cannot lose. It is only by comparing Petrarch's own philosophy of literature with the dulness of the schoolmen in their decadence, and with the stylistic shallowness of subsequent scholars, that we come to comprehend how luminous and novel was the thesis he supported.
