To what length Antony would have gone in his career of usurpation it is difficult to say, had he not been opposed at this point by Caius Octavius, the grand-nephew of Julius Cæsar, and the one whom he had named in his will as his heir and successor. Upon the Senate declaring in favor of Octavius, civil war immediately broke out between him and Antony and Lepidus. After several indecisive battles between the forces of the rival competitors, Octavius proposed to Antony and Lepidus a reconciliation. The three met on a small island in the Rhenus, a little stream in Northern Italy, and there formed a league known as the Second Triumvirate (43 B.C.).

The plans of the triumvirs were infamous. They first divided the world among themselves: Octavius was to have the government of the West; Antony, that of the East; while to Lepidus fell the control of Africa. A general proscription, such as had marked the coming to power of Sulla (see p. 283), was then resolved upon. It was agreed that each should give up to the assassin such friends of his as had incurred the ill will of either of the other triumvirs. Under this arrangement Octavius gave up his friend Cicero,—who had incurred the hatred of Antony by opposing his schemes,— and allowed his name to be put at the head of the list of the proscribed.

The friends of the orator urged him to flee the country. "Let me die," said he, "in my fatherland, which I have so often saved!" His attendants were hurrying him, half unwilling, towards the coast, when his pursuers came up and despatched him in the litter in which he was being carried. His head was taken to Rome, and set up in front of the rostrum, "from which he had so often addressed the people with his eloquent appeals for liberty." It is told that Fulvia, the wife of Antony, ran her gold bodkin through the tongue, in revenge for the bitter philippics it had uttered against her husband. The right hand of the victim—the hand that had penned the eloquent orations—was nailed to the rostrum.

Cicero was but one victim among many hundreds. All the dreadful scenes of the days of Sulla were re-enacted. Three hundred senators and two thousand knights were murdered. The estates of the wealthy were confiscated, and conferred by the triumvirs upon their friends and favorites.

LAST STRUGGLE OF THE REPUBLIC AT PHILIPPI (42 B.C.).—The friends of the old republic, and the enemies of the triumvirs, were meanwhile rallying in the East. Brutus and Cassius were the animating spirits. The Asiatic provinces were plundered to raise money for the soldiers of the liberators. Octavius and Antony, as soon as they had disposed of their enemies in Italy, crossed the Adriatic into Greece, to disperse the forces of the republicans there. The liberators, advancing to meet them, passed over the Hellespont into Thrace.

Tradition tells how one night a spectre appeared to Brutus and seemed to say, "I am thy evil genius; we will meet again at Philippi." At Philippi, in Thrace, the hostile armies met (42 B.C.). In two successive engagements the new levies of the liberators were cut to pieces, and both Brutus and Cassius, believing the cause of the republic forever lost, committed suicide. It was, indeed, the last effort of the republic. The history of the events that lie between the action at Philippi and the establishment of the empire is simply a record of the struggles among the triumvirs for the possession of the prize of supreme power. After various redistributions of provinces, Lepidus was at length expelled from the triumvirate, and then again the Roman world, as in the times of Cæsar and Pompey, was in the hands of two masters—Antony in the East, and Octavius in the West.

ANTONY AND CLEOPATRA.—After the battle of Philippi, Antony went into Asia for the purpose of settling the affairs of the provinces and vassal states there. He summoned Cleopatra, the fair queen of Egypt, to meet him at Tarsus, in Cilicia, there to give account to him for the aid she had rendered the liberators. She obeyed the summons, relying upon the power of her charms to appease the anger of the triumvir. She ascended the Cydnus in a gilded barge, with oars of silver, and sails of purple silk. Beneath awnings wrought of the richest manufactures of the East, the beautiful queen, attired to personate Venus, reclined amidst lovely attendants dressed to represent cupids and nereids. Antony was completely fascinated, as had been the great Cæsar before him, by the dazzling beauty of the "Serpent of the Nile." Enslaved by her enchantments, and charmed by her brilliant wit, in the pleasure of her company he forgot all else—ambition and honor and country.

Once, indeed, Antony did rouse himself and break away from his enslavement to lead the Roman legions across the Euphrates against the Parthians. But the storms of approaching winter, and the incessant attacks of the Parthian cavalry, at length forced him to make a hurried and disastrous retreat. He hastened back to Egypt, and sought to forget his shame and disappointment amidst the revels of the Egyptian court.

THE BATTLE OF ACTIUM (31 B.C.).—Affairs could not long continue in their present course. Antony had put away his faithful wife Octavia for the beautiful Cleopatra. It was whispered at Rome, and not without truth, that he proposed to make Alexandria the capital of the Roman world, and announce Cæsarion, son of Julius Cæsar and Cleopatra, as heir of the empire. All Rome was stirred. It was evident that a conflict was at hand in which the question for decision would be whether the West should rule the East, or the East rule the West. All eyes were instinctively turned to Octavius as the defender of Italy, and the supporter of the sovereignty of the Eternal City. Both parties made the most gigantic preparations. Octavius met the combined fleets of Antony and Cleopatra just off the promontory of Actium, on the Grecian coast. While the issue of the battle that there took place was yet undecided, Cleopatra turned her galley in flight. The Egyptian ships, to the number of fifty, followed her example. Antony, as soon as he perceived the withdrawal of Cleopatra, forgot all else, and followed in her track with a swift galley. Overtaking the fleeing queen, the infatuated man was received aboard her vessel, and became her partner in the disgraceful flight.

The abandoned fleet and army surrendered to Octavius. The conqueror was now sole master of the civilized world. From this decisive battle (31 B.C.) are usually dated the end of the republic and the beginning of the empire. Some, however, make the establishment of the empire date from the year 27 B.C., as it was not until then that Octavius was formally invested with imperial powers.
