Zenobia would have ill deserved her reputation, had she indolently permitted the Emperor of the West to approach within a hundred miles of her capital. The fate of the East was decided in two great battles, so similar in almost every circumstance that we can scarcely distinguish them from each other, except by observing that the first was fought near Antioch and the second near Emesa. In both the Queen of Palmyra animated the armies by her presence, and devolved the execution of her orders on Zabdas, who had already signalized his military talents by the conquest of Egypt. The numerous forces of Zenobia consisted for the most part of light archers, and of heavy cavalry clothed in complete steel. The Moorish and Illyrian horse of Aurelian were unable to sustain the ponderous charge of their antagonists. They fled in real or affected disorder, engaged the Palmyrenians in a laborious pursuit, harassed them by a desultory combat, and at length discomfited this impenetrable but unwieldy body of cavalry. The light infantry, in the mean time, when they had exhausted their quivers, remaining without protection against a closer onset, exposed their naked sides to the swords of the legions. Aurelian had chosen these veteran troops, who were usually stationed on the Upper Danube, and whose valor had been severely tried in the Alemannic war. After the defeat of Emesa, Zenobia found it impossible to collect a third army. As far as the frontier of Egypt, the nations subject to her empire had joined the standard of the conqueror, who detached Probus, the bravest of his generals, to possess himself of the Egyptian provinces. Palmyra was the last resource of the widow of Odenathus. She retired within the walls of her capital, made every preparation for a vigorous resistance, and declared, with the intrepidity of a heroine, that the last moment of her reign and of her life should be the same.
Amid the barren deserts of Arabia, a few cultivated spots rise like islands out of the sandy ocean. Even the name of Tadmor, or Palmyra, by its signification in the Syriac as well as in the Latin language, denoted the multitude of palm-trees which afforded shade and verdure to that temperate region. The air was pure, and the soil, watered by some invaluable springs, was capable of producing fruits as well as corn. A place possessed of such singular advantages, and situated at a convenient distance between the Gulf of Persia and the Mediterranean,[C] was soon frequented by the caravans which conveyed to the nations of Europe a considerable part of the rich commodities of India. Palmyra insensibly increased into an opulent and independent city, and connecting the Roman and the Parthian monarchies by the mutual benefits of commerce, was suffered to observe a humble neutrality, till at length after the victories of Trajan the little republic sunk into the bosom of Rome, and flourished more than one hundred and fifty years in the subordinate though honorable rank of a colony. It was during that peaceful period, if we may judge from a few remaining inscriptions, that the wealthy Palmyrenians constructed those temples, palaces, and porticos of Grecian architecture whose ruins, scattered over an extent of several miles, have deserved the curiosity of our travelers. The elevation of Odenathus and Zenobia appeared to reflect new splendor on their country, and Palmyra for a while stood forth the rival of Rome: but the competition was fatal, and ages of prosperity were sacrificed to a moment of glory.
In his march over the sandy desert between Emesa and Palmyra, the Emperor Aurelian was perpetually harassed by the Arabs; nor could he always defend his army, and especially his baggage, from those flying troops of active and daring robbers who watched the moment of surprise and eluded the slow pursuit of the legions. The siege of Palmyra was an object far more difficult and important, and the Emperor, who with incessant vigor pressed the attacks in person, was himself wounded with a dart. "The Roman people," says Aurelian, in an original letter, "speak with contempt of the war which I am waging against a woman. They are ignorant both of the character and of the power of Zenobia. It is impossible to enumerate her warlike preparations of stones, of arrows, and of every species of missile weapons. Every part of the walls is provided with two or three balistæ, and artificial fires are thrown from her military engines. The fear of punishment has armed her with a desperate courage. Yet still I trust in the protecting deities of Rome, who have hitherto been favorable to all my undertakings." Doubtful, however, of the protection of the gods and of the event of the siege, Aurelian judged it more prudent to offer terms of an advantageous capitulation: to the Queen, a splendid retreat; to the citizens, their ancient privileges. His proposals were obstinately rejected, and the refusal was accompanied with insult.
The firmness of Zenobia was supported by the hope that in a very short time famine would compel the Roman army to repass the desert, and by the reasonable expectation that the kings of the East, and particularly the Persian monarch, would arm in the defense of their most natural ally. But fortune and the perseverance of Aurelian overcame every obstacle. The death of Sapor, which happened about this time, distracted the counsels of Persia, and the inconsiderable succors that attempted to relieve Palmyra were easily intercepted either by the arms or the liberality of the Emperor. From every part of Syria a regular succession of convoys safely arrived in the camp, which was increased by the return of Probus with his victorious troops from the conquest of Egypt. It was then that Zenobia resolved to fly. She mounted the fleetest of her dromedaries, and had already reached the banks of the Euphrates, about sixty miles from Palmyra, when she was overtaken by the pursuit of Aurelian's light horse, seized, and brought back a captive to the feet of the Emperor. Her capital soon afterwards surrendered, and was treated with unexpected lenity. The arms, horses, and camels, with an immense treasure of gold, silver, silk, and precious stones, were all delivered to the conqueror, who, leaving only a garrison of six hundred archers, returned to Emesa and employed some time in the distribution of rewards and punishments at the end of so memorable a war, which restored to the obedience of Rome those provinces that had renounced their allegiance since the captivity of Valerian.
When the Syrian Queen was brought into the presence of Aurelian he sternly asked her, How she had presumed to rise in arms against the emperors of Rome! The answer of Zenobia was a prudent mixture of respect and firmness: "Because I disdained to consider as Roman emperors an Aureolus or a Gallienus. You alone I acknowledge as my conqueror and my sovereign." But as female fortitude is commonly artificial, so it is seldom steady or consistent. The courage of Zenobia deserted her in the hour of trial; she trembled at the angry clamors of the soldiers, who called aloud for her immediate execution, forgot the generous despair of Cleopatra which she had proposed as her model, and ignominiously purchased life by the sacrifice of her fame and her friends. It was to their counsels, which governed the weakness of her sex, that she imputed the guilt of her obstinate resistance; it was on their heads that she directed the vengeance of the cruel Aurelian. The fame of Longinus, who was included among the numerous and perhaps innocent victims of her fear, will survive that of the Queen who betrayed or the tyrant who condemned him. Genius and learning were incapable of moving a fierce unlettered soldier, but they had served to elevate and harmonize the soul of Longinus. Without uttering a complaint he calmly followed the executioner, pitying his unhappy mistress, and bestowing comfort on his afflicted friends....
But, however in the treatment of his unfortunate rivals Aurelian might indulge his pride, he behaved towards them with a generous clemency which was seldom exercised by the ancient conquerors. Princes who without success had defended their throne or freedom, were frequently strangled in prison as soon as the triumphal pomp ascended the Capitol. These usurpers, whom their defeat had convicted of the crime of treason, were permitted to spend their lives in affluence and honorable repose. The Emperor presented Zenobia with an elegant villa at Tibur, or Tivoli, about twenty miles from the capital; the Syrian queen insensibly sunk into a Roman matron, her daughters married into noble families, and her race was not yet extinct in the fifth century.
FOUNDATION OF CONSTANTINOPLE
We are at present qualified to view the advantageous position of Constantinople, which appears to have been formed by nature for the centre and capital of a great monarchy. Situated in the forty-first degree of latitude, the imperial city commanded from her seven hills the opposite shores of Europe and Asia; the climate was healthy and temperate, the soil fertile, the harbor secure and capacious; and the approach on the side of the continent was of small extent and easy defense. The Bosphorus and the Hellespont may be considered as the two gates of Constantinople; and the prince who possessed those important passages could always shut them against a naval enemy and open them to the fleets of commerce. The preservation of the eastern provinces may in some degree be ascribed to the policy of Constantine, as the barbarians of the Euxine, who in the preceding age had poured their armaments into the heart of the Mediterranean, soon desisted from the exercise of piracy, and despaired of forcing this insurmountable barrier. When the gates of the Hellespont and Bosphorus were shut, the capital still enjoyed within their spacious inclosure every production which could supply the wants or gratify the luxury of its numerous inhabitants. The sea-coasts of Thrace and Bithynia, which languish under the weight of Turkish oppression, still exhibit a rich prospect of vineyards, of gardens, and of plentiful harvests; and the Propontis has ever been renowned for an inexhaustible store of the most exquisite fish, that are taken in their stated seasons without skill and almost without labor. But when the passages of the straits were thrown open for trade, they alternately admitted the natural and artificial riches of the North and South, of the Euxine and of the Mediterranean. Whatever rude commodities were collected in the forests of Germany and Scythia, as far as the sources of the Tanais and the Borysthenes; whatsoever was manufactured by the skill of Europe or Asia; the corn of Egypt, and the gems and spices of the farthest India, were brought by the varying winds into the port of Constantinople, which for many ages attracted the commerce of the ancient world.
The prospect of beauty, of safety, and of wealth, united in a single spot, was sufficient to justify the choice of Constantine. But as some decent mixture of prodigy and fable has in every age been supposed to reflect a becoming majesty on the origin of great cities, the Emperor was desirous of ascribing his resolution, not so much to the uncertain counsels of human policy as to the infallible and eternal decrees of Divine wisdom. In one of his laws he has been careful to instruct posterity that in obedience to the commands of God he laid the everlasting foundations of Constantinople: and though he has not condescended to relate in what manner the celestial inspiration was communicated to his mind, the defect of his modest silence has been liberally supplied by the ingenuity of succeeding writers, who describe the nocturnal vision which appeared to the fancy of Constantine as he slept within the walls of Byzantium. The tutelar genius of the city, a venerable matron sinking under the weight of years and infirmities, was suddenly transformed into a blooming maid, whom his own hands adorned with all the symbols of imperial greatness. The monarch awoke, interpreted the auspicious omen, and obeyed without hesitation the will of Heaven. The day which gave birth to a city or colony was celebrated by the Romans with such ceremonies as had been ordained by a generous superstition; and though Constantine might omit some rites which savored too strongly of their pagan origin, yet he was anxious to leave a deep impression of hope and respect on the minds of the spectators. On foot, with a lance in his hand, the Emperor himself led the solemn procession, and directed the line which was traced as the boundary of the destined capital; till the growing circumference was observed with astonishment by the assistants, who at length ventured to observe that he had already exceeded the most ample measure of a great city. "I shall still advance," replied Constantine, "till He, the invisible guide who marches before me, thinks proper to stop." Without presuming to investigate the nature or motives of this extraordinary conductor, we shall content ourselves with the more humble task of describing the extent and limits of Constantinople.
