The conquest of Hellas and gradual absorption of a part of her culture occupied the second century before the Christian era and the earlier years of the first. By this time, however, Rome herself had become a prey to the rivalries of political factions, beginning with the conspiracy of Sulla and ending with the civil war that followed upon the assassination of Julius Cæsar. The latter’s great-nephew, Octavianus, in conjunction with Marc Antony, conquered Brutus and Cassius at Philippi in Macedonia and Octavianus assumed authority over the West, while Antony established himself as ruler in the East. But his infatuation for Cleopatra raised the suspicion in Rome that he intended to marry her and make himself despot of an Oriental empire with Alexandria as its capital. War was declared against him as a national enemy and he was defeated at Actium, <small>B.C.</small> 31. The authority of Octavianus was now supreme. Republicanism, as a practical form of government, was dead. Conditions demanded one-man rule and Octavianus, in <small>B.C.</small> 27, resigned his office as Triumvir and received from the Senate the title of Augustus, which hitherto had been reserved for the gods. During this period of struggle the Hellenic influence had been rapidly growing. The sons of the ruling class had Greek tutors; many studied in the schools of Athens and Rhodes, and Roman writers began to emulate the Greek authors. Cæsar published his Commentaries on the Gallic War and on the Civil War; Sallust wrote on the Conspiracy of Catiline and the Jugurthine War and Cornelius Nepos compiled biographies of eminent men. Cicero published under the name of “Philippics” the speeches which he made against Antony in the Senate, as well as “Letters” to various friends on the topics of the times, while Lucretius composed in verse a treatise on the “Nature of the World” and Varro was the author of an encyclopædic work relating to the history, geography, agriculture, law, literature, philology, philosophy, and religion of the Romans. To Varro also had been assigned by Julius Cæsar the collection of a public Library of Greek and Roman writers. The enthusiasm for literature was encouraged by Augustus and his minister, Mycæenas, who saw in it a means of allaying the bitterness of party strife. To this, the “Augustan” or “Golden Age,” as the writers called it in flattery of their patron, belong Horace, Livy, and Virgil. In an effort also to lead the people back to the honourable simplicity of their forefathers, Augustus revived the ancient religious ceremonies and restored the temples. He became chief pontiff and, being regarded as the son of the deified Julius--in reality, his great-nephew--was treated almost as a divinity in Rome and deified by the provincials who built temples in his honour.
