After the discussion with the Greeks at Florence it was clear to all men that there was a deeper issue than the revival of classical learning, that there was a Christian as well as a pagan antiquity, and that the knowledge of the early Church depended on Greek writings, and was as essential a part of the Renaissance as the study of Homer or of Pindar. The inference was drawn by Nicholas V, the first Renaissance pontiff. He recognised the fact that a divine in full possession of Hellenic literature would be a more competent defender of tradition, a better writer, a stronger disputant, than the long line of scholastic teachers. He saw that it would be the means of renovating theology and disclosing the authentic and necessary evidences of historical religion. The most enlightened ecclesiastics of that age understood but vaguely that there was not only benefit and enrichment in a policy that favoured the new learning, but the only possible escape from a serious danger.
Religious knowledge in those days suffered not only from ignorance and the defect of testimony, but from an excess of fiction and falsification. Whenever a school was lacking in proofs for its opinions, it straightway forged them, and was sure not to be found out. A vast mass of literature arose, which no man, with medieval implements, could detect, and effectually baffled and deceived the student of tradition. At every point he was confronted by imaginary canons and constitutions of the apostles, acts of Councils, decretals of early Popes, writings of the Fathers from St. Clement to St. Cyril, all of them composed for the purpose of deceiving.
The example of Lorenzo Valla made it certain that all this was about to be exposed. The process that began with him lasted for two centuries, to the patriarchs of authentic erudition, Ussher and Pearson, Blondel and Launoy, the Bollandists of Antwerp and the Benedictines of Saint-Maur. It became apparent that the divines of many ages had been remarkable for their incapacity to find out falsehood, and for their dexterity in propagating it, and it made no little difference whether this tremendous exposure should be made by enemies, and should constitute one series of disasters for religion. This was prevented by the resolve of Pope Nicholas, that the Holy See should sanction and encourage the movement with its influence, its immense patronage, and all its opportunities. Therefore Valla, who had narrowly escaped alive from the Inquisition, became a functionary at the Vatican, and received 500 ducats from the Pope to translate Thucydides. Scholars were attracted by the papal collection of 5000 manuscripts, which were the foundation of the Vatican library, the first in the world after the fall of Constantinople.
The alliance between renovated Hellenism and the Papacy was ratified a few years later, when the most intelligent of the Italian Humanists, Aeneas Sylvius Piccolomini of Siena, was raised to the throne under the name of Pius II, and became the most modern of medieval Popes. He was one of those Churchmen in whom the classical spirit of the time predominated over the ecclesiastical. Twice there was a breach, and a momentary reaction; but on the whole the contract was observed, and the ancient pagans made their way under the shadow of St. Peter's better than the early Christians. Humanists of the type of Valla were domesticated by the prizes held out to them, from the pen of the secretary to the tiara of the pontiff. The apprehended explosion never came; the good and evil that was in the new scholars penetrated the court and modified its tone. Bibbiena's comedies were applauded at the Belvedere; The Prince was published by the Pope's printer, with the Pope's permission; a cardinal shrank from reading St. Paul, for fear of spoiling his style; and the scandals in the family of Borgia did not prevent bishops from calling him a god. Calixtus III said that he feared nothing from any hostile Powers, for he had 3000 men of letters to rely on. His successor, Aeneas Sylvius, considered that the decline of the empire was due to the fact that scholarship had gone over to the Papacy. The main fact in the Italian Renaissance is that an open conflict was averted at the cost of admitting into the hierarchy something of the profane spirit of the new men, who were innovators but not reformers. Ficino declares that there was no place where liberty prevailed as it did at Rome. Poggio, the mocking adversary of the clergy, was for half a century in the service of the Popes. Filelfo was handsomely rewarded by Nicholas for satires which would now be considered scarcely fit for publication. Aeneas Sylvius laughed at the Donation of Constantine, and wrote an account of his own Conclave in the tone of a fin de siecle journalist. He is indeed the founder of freedom of speech in History. When his History of his own time was published, a great number of passages injurious to his countrymen and to his ecclesiastical brethren had to be suppressed. They have been printed lately, and contain, in fifty pages, the concentrated essence of the wickedness of Italy. Platina wrote an angry and vindictive History of the Popes, and presented it to Sixtus IV, who made him librarian of the Vatican. Erasmus, who had a sort of clerical bias, warmly extols the light and liberty which he found at Rome in 1515, at the very eve of the Reformation.
There were branches of classical philology in which the Renaissance was backward. The general purpose was to set up Plato in the place of Aristotle, discredited as as accomplice of the obscurest schoolmen. Under the Medici, a Platonic academy flourished at Florence, with Ficino and Politian at its head. But there was a tendency to merge Plato in Neoplatonism, and to bridge over what separated him from Christianity. Neither the knowledge of Plato, nor the knowledge of the Gospel, profited by the endeavour. The only branch of literature in which the Renaissance gave birth to real classics, equal to the ancients, was politics. The medieval theory of politics restrained the State in the interest of the moral law of the Church, and of the individual. Laws are made for the public good, and, for the public good, they may be suspended. The public good is not to be considered, if it is purchased at the expense of an individual. Authorities are legitimate if they govern well. Whether they do govern well those whom they govern must decide. The unwritten laws reigns supreme over the municipal law. Modern sentiments such as these could not be sustained in the presence of indifference to religion, uncertainty as to another world, impatience of the past, and familiarity with Hellenistic thought. As the Church declined the ancient State appeared, a State which knew no Church, and was the greatest force on earth, bound by no code, a law to itself. As there is no such thing as right, politics are an affair of might, a mere struggle for power. Such was the doctrine which Venice practised, in the interest of a glorious and beneficent government, and which two illustrious writers, Machiavelli and Guicciardini, made the law of modern societies.
The one thing common to the whole Italian Renaissance was the worship of beauty. It was the aesthetic against the ascetic. In this exclusive study, that is, in art, the Italians speedily attained the highest perfection that has been reached by man. And it was reached almost simultaneously in many parts of Italy, Rome, Florence, Milan, and Venice. First, it was the triumph of classical over medieval models, and the suppression of Gothic. Then it was the outbreak of modern painting, beyond all models, medieval or ancient, in a generation of men remarkable for originality. Rome, which had adopted the new learning under the impulse of Nicholas V, went over also to the new art and became its metropolis. It was the ripest and most brilliant work of the time, and it was employed to give expression to religious ideas, and to decorate and exalt the dignity of the Papacy, with its headquarters at the Vatican. The man who conceived how much might be done by renascent art to give splendour to the Church at the moment when its terrestrial limits were immeasurably extended, and its political power newly established, was Julius II. In 1505 Emmanuel of Portugal, inspired by the prodigies of that epoch of discovery, and by the language of recent canonists, addressed him in these terms "Receive, at last, the entire globe, thou who art our god."
Julius, who, by the energy of his will and his passion for posthumous fame, was the true son of the Renaissance, asked Michael Angelo to construct a monument worthy of a pontiff who should surpass all his predecessors in glory. When the design proved too gigantic for any existing Church, he commanded Bramante to pull down the Basilica of Constantine, which for a thousand years had witnessed the dramatic scenes of ecclesiastical history, the coronation of Charlemagne, the enthronement of the dead Formosus, the arrest of Paschal, and to erect in its place a new and glorified St. Peter's, far exceeding all the churches of the universe in its dimensions, in beauty, in power over the imagination of men. The ruthless destruction indicates the tone of the new era. Old St. Peter's was not only a monument of history, but a sepulchre of saints.
Julius was not inspired by the Middle Ages. Under him the Papacy was preparing for a new career, less spiritual than what once had been, more politic and secular and splendid, under new stars. He had Bramante, Michael Angelo, Rafael, San Gallo, Peruzzi, a concentration of artistic genius such as had never been, not produced by Rome itself, but attracted from every quarter by the master of Rome. What had been, one hundred years before, a neglected provincial town, became the centre of European civilisation by the action of the Popes, and principally of one ambitious Pope. The Vatican paintings were largely political, commemorating the sovereign more than the priest, until St. Peter's was designed to exhibit the sublime grandeur and unity of the universal Church, and the authority of its head upon earth. It was the crowning triumph of the Renaissance. When he was dying, Julius said that the masses are impressed not by what they know, but by what they see. He transmitted to his successors the conception of a Church to be the radiant centre of religion and of art for mankind; and we shall see that this was, after all, a disastrous legacy.
The Renaissance, which was at its height in Italy after the middle of the fifteenth century, was checked by the wars of Charles V, the siege of Rome, and the Spanish domination. Toward 1540 Paolo Giovio says that scholarship had migrated from the Italians to the Germans; and the most learned Italian of the next generation, Baronius, knew no Greek. Before its decline in Italy it had found new homes beyond the Alps, especially in Germany. The Germans adopted the new learning much later, near a century later than the Italians, when an occasional student, such as Agricola and Reuchlin, visited Bologna or Rome. It spread slowly. Of the seventeen universities, some, such as at Vienna, Heidelberg, Erfurt, admitted the new studies; others, like Cologne, resisted. There was not the patriotic sentiment, the national enthusiasm. It was the importation of a foreign element, the setting up of an old enemy, the restoration of a world the Germans, under Alaric and Theodoric, had overthrown. They began with the invention of printing, which exactly coincided with the fall of Constantinople, as the earliest specimens of print are indulgences for the Turkish war. This gave assurance that the work of the Renaissance would last, that what was written would be accessible to all, that such an occultation of knowledge and ideas as had depressed the Middle Ages would never recur, that not an idea would be lost. They got their classics generally from Italy; but after Aldus had published his series of ancient writers, still treasured by those whom Greek contractions do not repel, the New Testament and the Fathers, edited by Erasmus, were printed at Bale by Froben and Amerbach.
The pagan spirit, the impatience of Christianity, appears only in one or two Germans, such as Mutianus Rufus, who kept his convictions to himself. There were no great theologians, but there was the greatest religious writer that ever lived, the author of the Imitation, and he was not a solitary thinker, but a member of a congregation which kept religion alive, especially in North Germany. The opposition which arose was stronger and more defined than anything in Italy, but it was against Catholicism, not against Christianity.
