Corruption, the most infallible symptom of constitutional liberty. - Edward Gibbon

The pilgrimage of Italy, which I now accomplished, had long been the object of my curious devotion. The passage of Mount Cenis, the regular streets of Turin, the Gothic cathedral of Milan, the scenery of the Boromean Islands, the marble palaces of Genoa, the beauties of Florence, the wonders of Rome, the curiosities of Naples, the galleries of Bologna, the singular aspect of Venice, the amphitheatre of Verona, and the Palladian architecture of Vicenza, are still present to my imagination. I read the Tuscan writers on the banks of the Arno; but my conversation was with the dead rather than the living, and the whole college of Cardinals was of less value in my eyes than the transfiguration of Raphael, the Apollo of the Vatican, or the massy greatness of the Coliseum. It was at Rome, on the fifteenth of October, 1764, as I sat musing amidst the ruins of the Capitol, while the barefooted fryars were singing Vespers in the temple of Jupiter, that the idea of writing the decline and fall of the City first started to my mind. After Rome has kindled and satisfied the enthusiasm of the Classic pilgrim, his curiosity for all meaner objects insensibly subsides.

The theologian may indulge the pleasing task of describing Religion as she descended from Heaven, arrayed in her native purity. A more melancholy duty is imposed on the historian. He must discover the inevitable mixture of error and corruption, which she contracted in a long residence upon earth, among a weak and degenerate race of beings.

The names of Seneca, of the elder and the younger Pliny, of Tacitus, of Plutarch, of Galen, of the slave Epictetus, and of the emperor Marcus Antoninus, adorn the age in which they flourished, and exalt the dignity of human nature. They filled with glory their respective stations, either in active or contemplative life; their excellent understandings were improved by study; philosophy had purified their minds from the prejudices of the popular superstition; and their days were spent in the pursuit of truth and the practice of virtue. Yet all these sages (it is no less an object of surprise than of concern) overlooked or rejected the perfection of the Christian system. Their language or their silence equally discover their contempt for the growing sect which in their time had diffused itself over the Roman empire. Those among them who condescend to mention the Christians consider them only as obstinate and perverse enthusiasts, who exacted an implicit submission to their mysterious doctrines, without being able to produce a single argument that could engage the attention of men of sense and learning.
