are of a relative nature: the traveller, and especially the poet, who sailed along the Hellespont, who pursued the windings of the stream, and contemplated the rural scenery, which appeared on every side to terminate the prospect, insensibly lost the remembrance of the sea; and his fancy painted those celebrated straits, with all the attributes of a mighty river flowing with a swift current, in the midst of a woody and inland country, and at length, through a wide mouth, discharging itself into the Ægean or Archipelago. Ancient Troy, seated on a an eminence at the foot of Mount Ida, overlooked the mouth of the Hellespont, which scarcely received an accession of waters from the tribute of those immortal rivulets the Simois and Scamander. The Grecian camp had stretched twelve miles along the shore from the Sigæan to the Rhætean promontory; and the flanks of the army were guarded by the bravest chiefs who fought under the banners of Agamemnon. The first of those promontories was occupied by Achilles with his invincible myrmidons, and the dauntless Ajax pitched his tents on the other. After Ajax had fallen a sacrifice to his disappointed pride, and to the ingratitude of the Greeks, his sepulchre was erected on the ground where he had defended the navy against the rage of Jove and of Hector; and the citizens of the rising town of Rhæteum celebrated his memory with divine honors. Before Constantine gave a just preference to the situation of Byzantium, he had conceived the design of erecting the seat of empire on this celebrated spot, from whence the Romans derived their fabulous origin. The extensive plain which lies below ancient Troy, towards the Rhætean promontory and the tomb of Ajax, was first chosen for his new capital; and though the undertaking was soon relinquished the stately remains of unfinished walls and towers attracted the notice of all who sailed through the straits of the Hellespont.

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 defence. 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 enclosure 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, and 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.
