CHAP. val in a camp near Hadrianople, which he had fortified with an anxious care that betrayed his apprehension of the event. Constantine directed his march from Thessalonica towards that part of Thrace, till he found himself stopped by the broad and rapid stream of the Hebrus, and discovered the numerous army of Licinius, which filled the steep ascent of the hill, from the river to the city of Hadrianople. Many days were spent in doubtful and distant skirmishes; but at length the ob stacles of the passages and of the attack were removed by the intrepid conduct of Constantine. In this place we might relate a wonderful exploit of Constantine, which, though it can scarcely be paralleled either in poetry or romance, is celebrated, not by a venal orator devoted to his fortune, but by an historian, the partial enemy of his fame. We are assured that the valiant emperor threw himself into the river Hebrus, accompanied only by twelve horsemen, and that by the effort or terror of his invincible arm, he broke, slaughtered, and put to flight a host of an hundred and fifty thousand men. The credulity of Zosimus prevailed so strongly over his passion, that among the events of the memorable battle of Hadrianople, he seems to have selected and embellished, not the most important, but the most marvellous. The valour and danger of Constantine are attested by a slight wound which he received in the thigh, but it may be discovered even from an imperfect narration, and perhaps a corrupted text, that the victory was obtained no less by the conduct of the general than by the courage of the hero; that a body of five thousand archers marched round to occupy a thick wood in the rear of the enemy, whose attention was diverted by the construction of a bridge, and that Licinius, perplexed by so many artful evolutions, was reluctantly drawn from his advantageous post to combat on equal ground in the plain. The contest was no longer equal. His confused multitude of new levies was easily vanquished by the experienced veterans of the West. Thirty-four thousand men are reported to have been slain. The fortified camp of Licinius was taken by assault the evening of the battle; the greater part of the

tium, and

Crispus.

The siege of Byzantium, which was immediately un-Siege of dertaken by Constantine, was attended with great la- Byzan bour and uncertainty. In the late civil wars, the for- naval victifications of that place, so justly considered as the tory of key of Europe and Asia, had been repaired and strengthened; and as long as Licinius remained master of the sea, the garrison was much less exposed to the danger of famine than the army of the besiegers. The naval commanders of Constantine were summoned to his camp, and received his positive orders to force the passage of the Hellespont, as the fleet of Licinius, instead of seeking and destroying their feeble enemy, continued inactive in those narrow straits where its superiority of numbers was of little use or advantage. Crispus, the emperor's eldest son, was intrusted with the execution of this daring enterprise, which he performed with so much courage and success, that he deserved the esteem, and most probably excited the jealousy, of his father. The engagement lasted two days, and in the evening of the first, the contending fleets, after a considerable and mutual loss, retired into their respective harbours of Europe and Asia. The second day about noon a strong south wind 108 sprang up, which carried the vessels of Crispus against the enemy, and as the casual advantage was improved by his skilful intrepidity, he soon obtained a complete victory. An hundred and thirty vessels were destroyed, five thousand men were slain, and Amandus, the admiral of the Asiatic fleet, escaped

107 Zosimus, l. ii. p. 95, 96. This great battle is described in the Valesian Fragment (p. 714.) in a clear though concise manner. "Licinius vero circum Hadrianopolin maximo exercitu latera ardui montis impleverat; illuc toto agmine Constantinus inflexit. Cum bellum terrâ marique traheretur, quamvis per arduum suis nitentibus, attamen disciplinâ militari et felicitate, Constantinus Licinii confusum et sine ordine agentem vicit exercitum; leviter femore sauciatus."

108 Zosimus, l. ii. p. 97, 98. The current always sets out of the Hellespont; and when it is assisted by a north wind, no vessel can attempt the passage. A south wind renders the force of the current almost imperceptible. See Tournefort's Voyage au Levant, Let. xi.

CHAP. with the utmost difficulty to the shores of Chalcedon. As soon as the Hellespont was open, a plentiful convoy of provisions flowed into the camp of Constantine, who had already advanced the operations of the siege. He constructed artificial mounds of earth of an equal height with the ramparts of Byzantium. The lofty towers which were erected on that foundation, galled the besieged with large stones and darts from the military engines, and the battering rams had shaken the walls in several places. If Licinius persisted much longer in the defence, he exposed himself to be involved in the ruin, of the place. Before he was surrounded he prudently removed his person and treasures to Chalcedon in Asia; aud as he was always desirous of associating companions to the hopes and dangers of his fortune, he now bestowed the title of Cæsar on Martinianus, who exercised one of the most important offices of the empire109.

Battle of

polis.

Such were still the resources, and such the abilities, Chryso- of Licinius, that, after so many successive defeats, he collected in Bithynia a new army of fifty or sixty thousand men, while the activity of Constantine was employed in the siege of Byzantium. The vigilant emperor did not however neglect the last struggles of his antagonist. A considerable part of his victorious army was transported over the Bosphorus in small vessels, and the decisive engagement was fought soon after their landing on the heights of Chrysopolis, or, as it is now called, of Scutari. The troops of Licinius, though they were lately raised, ill armed, and worse disciplined, made head against their conquerors with fruitless but desperate valour, till a total defeat and the slaughter of five and twenty thousand men irretrievably determined the fate of their leader11. He retired to Nicomedia, rather with the view of gaining

110 Eusebius (in Vitâ Constantin. 1. ii. c. 16, 17.) ascribes this decisive victory to the pious prayers of the emperor. The Valesian Fragment (p. 714.) mentions a body of Gothic auxiliaries, under their chief Aliquaca, who adhered to the party of Licinius.

some time for negotiation, than with the hope of any CHAP. effectual defence. Constantia, his wife and the sister of Constantine, interceded with her brother in favour of her husband, and obtained from his policy rather than from his compassion, a solemn promise, confirmed by an oath, that after the sacrifice of Martinianus, and the resignation of the purple, Licinius himself should be permitted to pass the remainder of his life in peace and affluence. The behaviour of Constantia, and her relation to the contending parties, naturally recalls the remembrance of that virtuous matron who was the sister of Augustus, and the wife of Antony.-But the temper of mankind was altered, and it was no longer esteemed infamous for a Roman to survive his konour and independence. Licinius solicited and accepted the pardon of his offences, laid himself and his purple at the feet of his lord and master, was raised from the ground with insulting pity, was admitted the same day to the Imperial banquet, and soon afterwards was sent away to Thessalonica, which had been chosen for the place of his confinement". His confinement was soon terminated by death, and it is doubtful whether a tumult of the soldiers, or a decree of the senate, was suggested as a motive for his execution. According to the rules of tyranny, he was accused of forming a conspiracy, and of holding a treasonable correspondence with the barbarians; but as he was never convicted, either by his own conduct or by any legal evidence, we may perhaps be allowed, from his weakness, to presume his innocence". The memory of Licinius was branded with infamy, his statues were thrown down, and, by a hasty edict, of such mischievous tendency that it was almost immediately corrected, all his laws, and all the judicial proceed

The successive steps of the elevation of Constantine, from his first assuming the purple at York, to the resignation of Licinius at Nicomedia, have been related with some minuteness and precision, not only as the events are in themselves both interesting and important, but still more, as they contributed to the decline of the empire by the expense of blood and treasure, and by the perpetual increase, as well of the taxes, as of the military establishment. The foundation of Constantinople, and the establishment of the Christian religion, were the immediate and memorable consequences of this revolution.

113 See the Theodosian Code, 1. xv. tit. 15. tom. v. p. 404, 405. These edicts of Constantine betray a degree of passion and precipitancy very ans becoming of the character of a lawgiver.
