In striking contrast to Celsus as regards width of knowledge and literary skill, though no less famous in the history of his own art, is his contemporary, the celebrated architect Vitruvius Pollio. The ten books De Architectura, dedicated to Augustus about the year 14 B.C., are the single important work on classical architecture which has come down from the ancient world, and, as such, have been the object of continuous professional study from the Renaissance down to the present day. But their reputation is not due to any literary merit. Vitruvius, however able as an architect, was a man of little general knowledge, and far from handy with his pen. His style varies between immoderate diffuseness and obscure brevity; sometimes he is barely intelligible, and he never writes with grace. Where in his introductory chapters or elsewhere he ventures beyond his strict province, his writing is that of a half-educated man who has lost simplicity without acquiring skill.
Among the innumerable rhetoricians of this age one only requires formal notice, Lucius Annaeus Seneca of Cordova, the father of the famous philosopher, and the grandfather of the poet Lucan. His long life reached from before the outbreak of war between Caesar and Pompeius till after the death of Tiberius. His only extant work, a collection of themes treated in the schools of rhetoric, was written in his old age, after the fall of Sejanus, and bears witness to the amazing power of memory which he tells us himself was, when in its prime, absolutely unique. How much of his life was spent at Rome is uncertain. As a young man he had heard all the greatest orators of the time except Cicero; and up to the end of his life he could repeat word for word and without effort whole passages, if not whole speeches, to which he had listened many years before. His ten books of Controversiae are only extant in a mutilated form, which comprises thirty-five out of seventy-four themes; to these is prefixed a single book of Suasoriae, which is also imperfect. The work is a mine of information for the history of rhetoric under Augustus and Tiberius, and incidentally includes many interesting quotations, anecdotes, and criticisms. But we feel in reading it that we have passed definitely away from the Golden Age. Yet once more "they have forgotten to speak the Latin tongue at Rome." The Latinity of the later Empire is as distinct from that of the Augustan age as this last is from the Latinity of the Republic. Seneca, it is true, was not an Italian by birth; but it is just this influx of the provinces into literature, which went on under the early Empire with continually accelerating force, that determined what type the new Latinity should take. Gaul, Spain, and Africa are henceforth side by side with Italy, and Italy herself sinks towards the level of a province. Within thirty years of the death of the elder Seneca "the fatal secret of empire, that Emperors could be made elsewhere than at Rome," was discovered by the Spanish and German legions; of hardly less moment was the other discovery, that Latin could be written in another than the Roman manner. In literature no less than in politics the discovery meant the final breaking up of the old world, and the slow birth of a new one through alternate torpors and agonies. It might already have been said of Rome, in the words of a poet of four hundred years later, that she had made a city of what had been a world. But in this absorption of the world into a single citizenship, the city itself was ceasing to be a world of its own; and with the self-centred urbs passed away the urbanus sermo, that austere and noble language which was the finest flower of her civilisation.

THE EMPIRE.
I
THE ROME OF NERO: SENECA, LUCAN, PETRONIUS
The later years of the Julio-Claudian dynasty, while they brought about the complete transformation of the government into an absolute monarchy, also laid the foundations for that reign of the philosophers which had been dreamed of by Plato, and which has never been so nearly realised as it was in Rome during the second century after Christ. The Stoical philosophy, passing beyond the limits of the schools to become at once a religious creed and a practical code of morals for everyday use, penetrated deeply into the life of Rome. At first associated with the aristocratic opposition to the imperial government, it passed through a period of persecution which only strengthened and consolidated its growth. The final struggle took place under Domitian, whose edict of the year 94, expelling all philosophers from Rome, was followed two years afterwards by his assassination and the establishment, for upwards of eighty years, of a government deeply imbued with the principles of Stoicism.
Of the men who set this revolution in motion by their writings, the earliest and the most distinguished was Lucius Annaeus Seneca, the son of the rhetorician. Though only of the second rank as a classic, he is a figure of very great importance in the history of human thought from the work he did in the exposition of the new creed. As a practical exponent of morals, he stands, with Plutarch, at the head of all Greek and Roman writers.
The life of Seneca was one of singularly dramatic contrasts and vicissitudes. He was born in the year 4 B.C., at Cordova, where, at a somewhat advanced age, his father had married Helvia, a lady of high birth, and brought up in the strictest family traditions. Through the influence of his mother's family (her sister had married Vitrasius Pollio, who for sixteen years was viceroy of Egypt), the way was easy to him for advancement in the public service. But delicate health, which continued throughout his life, kept him as a young man from taking more than a nominal share in administrative work. He passed into the senate through the quaestorship, and became a well-known figure at court during the reign of Caligula. On the accession of Claudius, he was banished to Corsica at the instance of the Empress Messalina, on the charge of being the favoured lover of Julia Livilla, Caligula's youngest sister. Whether the scandal which connected his name with hers, or with that of her sister Agrippina, had any other foundation than the prurient gossip which raged round all the members of the imperial family, may well be doubted; but when Agrippina married Claudius, after the downfall and execution of Messalina seven years later, she recalled him from exile, obtained his nomination to the quaestorship, and appointed him tutor to her son Domitius Nero, then a boy of ten. The influence gained by Seneca, an accomplished courtier and a clever man of the world, as well as a brilliant scholar, over his young pupil was for a long time almost unbounded; and when Nero became Emperor at the age of seventeen, Seneca, in conjunction with his close friend, Afranius Burrus, commander of the imperial guards, became practically the administrator of the Empire. His philosophy was not one which rejected wealth or power; a fortune of three million pounds may have been amassed without absolute dishonesty, or even forced upon him, as he pleads himself, by the lavish generosity of his pupil; but there can be no doubt that in indulging the weaknesses and passions of Nero, Seneca went far beyond the limits, not only of honour, but of ordinary prudence. The mild and enlightened administration of the earlier years of the new reign, the famous quinquennium Neronis, which was looked back to afterwards as a sort of brief golden age, may indeed be ascribed largely to Seneca's influence; but this influence was based on an excessive indulgence of Nero's caprices, which soon worked out its own punishment. His consent to the murder of Agrippina was the death-blow to his influence for good, or to any self-respect that he may till then have retained; the death of Burrus left him without support; and, by retiring into private life and formally offering to make over his whole fortune to the Emperor, he did not long delay his fate. In the year 65, on the pretext of complicity in the conspiracy of Piso, he was commanded to commit suicide, and obeyed with that strange mixture of helplessness and heroism with which the orders of the master of the world were then accepted as a sort of inevitable law of nature.
The philosophical writings of Seneca were extremely voluminous; and though a large number of them are lost, he is still one of the bulkiest of ancient authors. They fall into three main groups: formal treatises on ethics; moral letters (epistolae morales), dealing in a less continuous way with the same general range of subjects; and writings on natural philosophy, from the point of view of the Stoical system. The whole of these are, however, animated by the same spirit; to the Stoical philosophy, physics were merely a branch of ethics, and a study to be pursued for the sake of moral edification, not of reaching truth by accurate observation or research. The discussions of natural phenomena are mere texts for religious meditations; and though the eight books of Naturales Quaestiones were used as a text-book of physical science in the Middle Ages, they are totally without any scientific value. So, too, the twenty books of moral letters, nominally addressed to Lucilius, the procurator of Sicily, merely represent a slight variation of method from the more formal treatises, On Anger, On Clemency, On Consolation, On Peace of Mind, On the Shortness of Life, On Giving and Receiving Favours, which are the main substance of Seneca's writings.
