"The harbour of Constantinople, which may be considered as an arm of the Bosphorus, 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 the 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 Bosphorus 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 the city from the attack of an hostile navy.

"Between the Bosphorus and the Hellespont, the shores of Europe and Asia receding on either side include the Sea of Marmora, which was known to the ancients by the denomination of the Propontis. The navigation from the issue of the Bosphorus 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 highlands 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 again contracted to 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 Sestos and Abydos. 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 an 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 Scamander. The Grecian camp had stretched twelve miles along the shore from the Sigæan to the Rhætian promontory, and the flanks of the army were guarded by the bravest chiefs who fought under the banners of Agamemnon. The first of these 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 Hector, and the citizens of the rising town of Rhætium 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 Rhætian promontory 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 Bosphorus and the Hellespont may be considered as the two gates of Constantinople, and the prince who possesses 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 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 the Mediterranean. Whatever rude commodities were collected in the forests of Germany and Scythia, and as far as the sources of the Tanais and Borysthenes; whatsoever was manufactured by the skill of Europe or Asia, the corn of Egypt, the gems and spices of the furthest 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 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 eternal and infallible 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 a 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 savoured 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.'"

Gibbon proceeds to describe the extent, limits, and edifices of Constantinople. Unfortunately the limits of our space prevent us from giving more than a portion of his brilliant picture.

"In the actual state of the city the palace and gardens of the Seraglio occupy the eastern promontory, the first of the seven hills, and cover about one hundred and fifty acres of our own measure. The seat of Turkish jealousy and despotism is erected on the foundations of a Grecian republic: but it may be supposed that the Byzantines were tempted by the conveniency of the harbour to extend their habitations on that side beyond the modern limits of the Seraglio. The new walls of Constantine stretched from the port to the Propontis across the enlarged breadth of the triangle, at the distance of fifteen stadia from the ancient fortifications: and with the city of Byzantium they inclosed five of the seven hills, which to the eyes of those who approach Constantinople appear to rise above each other in beautiful order. About a century after the death of the founder the new buildings, extending on one side up the harbour, and on the other the Propontis, already covered the narrow ridge of the sixth and the broad summit of the seventh hill. The necessity of protecting those suburbs from the incessant inroads of the barbarians engaged the younger Theodosius to surround his capital with an adequate and permanent inclosure of walls. From the eastern promontory to the Golden Gate, the extreme length of Constantinople was above three Roman miles; the circumference measured between ten and eleven; and the surface might be computed as equal to about two thousand English acres. It is impossible to justify the vain and credulous exaggerations of modern travellers, who have sometimes stretched the limits of Constantinople over the adjacent villages of the European and even Asiatic coasts. But the suburbs of Pera and Galata, though situate beyond the harbour, may deserve to be considered as a part of the city, and this addition may perhaps authorise the measure of a Byzantine historian, who assigns sixteen Greek (about sixteen Roman) miles for the circumference of his native city. Such an extent may seem not unworthy of an imperial residence. Yet Constantinople must yield to Babylon and Thebes, to ancient Rome, to London, and even to Paris....

"Some estimate may be formed of the expense bestowed with imperial liberality on Constantinople, by the allowance of about two millions five hundred thousand pounds for the construction of the walls, the porticoes, and the aqueducts. The forests that overshadowed the shores of the Euxine, and the celebrated quarries of white marble in the little island of Proconnesus, supplied an inexhaustible stock of materials ready to be conveyed by the convenience of a short water carriage to the harbour of Byzantium. A multitude of labourers and artificers urged the conclusion of the work with incessant toil, but the impatience of Constantine soon discovered that in the decline of the arts the skill as well as the number of his architects bore a very unequal proportion to the greatness of his design.... The buildings of the new city were executed by such artificers as the age of Constantine could afford, but they were decorated by the hands of the most celebrated masters of the age of Pericles and Alexander.... By Constantine's command the cities of Greece and Asia were despoiled of their most valuable ornaments. The trophies of memorable wars, the objects of religious veneration, the most finished statues of the gods and heroes, of the sages and poets of ancient times, contributed to the splendid triumph of Constantinople.

"... The Circus, or Hippodrome, was a stately building of about four hundred paces in length and one hundred in breadth. The space between the two metæ, or goals, was filled with statues and obelisks, and we may still remark a very singular fragment of antiquity—the bodies of three serpents twisted into one pillar of brass. Their triple heads had once supported the golden tripod which, after the defeat of Xerxes, was consecrated in the temple of Delphi by the victorious Greeks. The beauty of the Hippodrome has been long since defaced by the rude hands of the Turkish conquerors; but, under the similar appellation of Atmeidan, it still serves as a place of exercise for their horses. From the throne whence the emperor viewed the Circensian games a winding staircase descended to the palace, a magnificent edifice, which scarcely yielded to the residence of Rome itself, and which, together with the dependent courts, gardens, and porticoes, covered a considerable extent of ground upon the banks of the Propontis between the Hippodrome and the church of St. Sophia. We might likewise celebrate the baths, which still retained the name of Zeuxippus, after they had been enriched by the magnificence of Constantine with lofty columns, various marbles, and above three score statues of bronze. But we should deviate from the design of this history if we attempted minutely to describe the different buildings or quarters of the city.... A particular description, composed about a century after its foundation, enumerates a capitol or school of learning, a circus, two theatres, eight public and one hundred and fifty-three private baths, fifty-two porticoes, five granaries, eight aqueducts or reservoirs of water, four spacious halls for the meeting of the senate or courts of justice, fourteen churches, fourteen palaces, and four thousand three hundred and eighty-eight houses, which for their size or beauty deserved to be distinguished from the multitude of plebeian habitations."

Gibbon's conception of history was that of a spacious panorama, in which a series of tableaux pass in succession before the reader's eye. He adverts but little, far too little, to that side of events which does not strike the visual sense. He rarely generalises or sums up a widely-scattered mass of facts into pregnant synthetic views. But possibly he owes some of the permanence of his fame to this very defect. As soon as ever a writer begins to support a thesis, to prove a point, he runs imminent danger of one-sidedness and partiality in his presentation of events. Gibbon's faithful transcript of the past has neither the merit nor the drawback of generalisation, and he has come in consequence to be regarded as a common mine of authentic facts to which all speculators can resort.
