# Constantinople: A Sketch of its History from its Foundation to its Conquest by the Turks in 1453/Introduction

INTRODUCTION.
"F we survey Byzantium in the extent which it acquired with the august name of Constantinople, the figure of the imperial city may be represented under that of an unequal triangle. The obtuse point, which advances towards the east and the shores of Asia, meets and repels the waves of the Thracian Bosporus. The northern side of the city is bounded by the harbour, and the southern is washed by the Propontis, or Sea of Marmora. The basis of the triangle is opposed to the west, and terminates the continent of Europe. But the admirable form and division of the circumjacent land and water cannot, without a more ample explanation, be clearly or sufficiently understood.
"The winding channel through which the waters of the Euxine flow with a rapid and incessant course towards the Mediterranean, received the appellation of Bosporus, a name not less celebrated in the history, than in the fables, of antiquity. A crowd of temples and of votive altars profusely scattered along its steep and woody banks attested the unskilfulness, the terrors, and the devotion of the Grecian navigators, who, after the ex​ample of the Argonauts, explored the dangers of the inhospitable Euxine. On these banks tradition long preserved the memory of the palace of Phineus, infested by the obscene harpies; and of the sylvan reign of Amycus, who defied the son of Leda to the combat of the cestus. The straits of the Bosporus are terminated by the Cyanean rocks, which, according to the description of the poets, had once floated on the face of the waters, and were destined by the gods to protect the entrance of the Euxine against the eye of profane curiosity. From the Cyanean rocks to the point and harbour of Byzantium the winding length of the Bosporus extends about sixteen miles, and its most ordinary breadth may be computed at about one mile and a half. The new castles of Europe and Asia are constructed, on either continent, upon the foundations of two celebrated temples, of Serapis and of Jupiter Urius. The old castles, a work of the Greek emperors, command the narrowest part of the channel, in a place where the opposite banks advance within five hundred paces of each other. These fortresses were destroyed and strengthened by Mahomet the Second, when he meditated the siege of Constantinople; but the Turkish conqueror was most probably ignorant that near two thousand years before his reign Darius had chosen the same situation to connect the two continents by a bridge of boats. At a small distance from the old castles we discover the little town of Chrysopolis, or Scutari, which may almost be considered as the Asiatic suburb of Constantinople. The Bosporus, as it begins to open ​into the Propontis, passes between Byzantium and Chalcedon. The latter of those cities was built by the Greeks, a few years before the former; and the blindness of its founders, who overlooked the superior advantages of the opposite coast, has been stigmatized by a proverbial expression of contempt.
"The harbour of Constantinople, which may be considered as an arm of the Bosporus, obtained, in a very remote period, the denomination of the Golden Horn. The curve which it describes might be compared to the horn of a stag, or as it should seem, with more propriety, to that of an ox. The epithet of golden was expressive of the riches which every wind wafted from the most distant countries into the secure and capacious port of Constantinople. The river Lycus, formed by the conflux of two little streams, pours into the harbour a perpetual supply of fresh water, which serves to cleanse the bottom, and to invite the periodical shoals of fish to seek their retreat in that convenient recess. As the vicissitudes of tides are scarcely felt in those seas, the constant depth of the harbour allows goods to be landed on the quays without the assistance of boats; and it has been observed that in many places the largest vessels may rest their prows against the houses, while their sterns are floating in the water. From the mouth of the Lycus to that of the harbour, this arm of the Bosporus is more than seven miles in length. The entrance is about five hundred yards broad, and a strong chain could be occasionally drawn across it, to guard the port and city from the attack of a hostile navy.
​"Between the Bosporus and the Hellespont the shores of Europe and Asia, receding on either side, enclose the Sea of Marmora, which was known to the ancients by the denomination of Propontis. The navigation from the issue of the Bosporus to the entrance of the Hellespont is about one hundred and twenty miles. Those who steer their westward course through the middle of the Propontis may at once descry the high lands of Thrace and Bithynia, and never lose sight of the lofty summit of Mount Olympus, covered with eternal snows. They leave on the left a deep gulf, at the bottom of which Nicomedia was seated, the imperial residence of Diocletian; and they pass the small islands of Cyzicus and Proconnesus before they cast anchor at Gallipoli, where the sea, which separates Asia from Europe, is contracted into a narrow channel.
"The geographers who, with the most skilful accuracy, have surveyed the form and extent of the Hellespont, assign about sixty miles for the winding course, and about three miles for the ordinary breadth of those celebrated straits. But the narrowest part of the channel is found to the northward of the old Turkish castles between the cities of Sestus and Abydus. It was here that the adventurous Leander braved the passage of the flood for the possession of his mistress. It was here likewise, in a place where the distance between the opposite banks cannot exceed five hundred paces, that Xerxes imposed a stupendous bridge of boats, for the purpose of transporting into Europe a hundred and seventy myriads of barbarians. A sea contracted within ​such narrow limits may seem but ill to deserve the singular epithet of broad, which Homer, as well as Orpheus, has frequently bestowed on the Hellespont. But our ideas of greatness 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 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 the 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 banner 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 honours. 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 harbour secure and capacious, and the approach on the side of the continent was of small extent and easy defence. The Bosporus 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 Bosporus 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 labour. 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."
