Constantinople, situated between Europe and Asia, between the Archipelago and the Black Sea, joins together the two seas and the two continents. In the times of its splendour, it held at its pleasure the gates of commerce open or shut; its port, which received the vessels of all the nations of the world, deserved to be termed by the Greeks, _the golden horn_, or _the horn of abundance_. Like ancient Rome, Constantinople extended over seven ascents, and, like the city of Romulus, it sometimes bore the name of the city of the seven hills; in the times of the crusades, its walls and its towers were compared to those of Babylon; its deep ditches were converted at will into a large and rapid lake, and the city could, at the least signal, be surrounded by waters, and separated from the continent.
The monarch who founded it reigned over all the known nations of the world, and in the execution of his designs he had the advantage of making the arts and sciences of Greece concur with the genius and power of the Romans. Not content with employing the beautiful marbles of the isles of the Archipelago, he caused materials to be transported from the extremities of Europe and Asia; all the cities of the Roman empire, Athens, and Rome itself, were spoiled of their ornaments to embellish the new city of the Cæsars. Several of the successors of Constantine had repaired the edifices that were crumbling into ruins, and had erected fresh monuments in Constantinople, which in its temples, upon its public places, and around the walls, everywhere recalled the memory of twenty glorious reigns. The city was divided into fourteen quarters; it had thirty-two gates; it contained within its bosom circuses of immense extent, five hundred churches, among which St. Sophia claimed attention as one of the wonders of the world; and five palaces, which themselves looked like cities in the midst of the great city. More fortunate than its rival Rome, the city of Constantine had never beheld the barbarians within its walls; it preserved with its language the depository of the masterpieces of antiquity, and the accumulated riches of the East and the West.
It would be difficult to paint the enthusiasm, the fear, the surprise that took possession of the minds of the Crusaders at the aspect of Constantinople.[90] The leaders landed, and passed one night in the abbey of St. Stephen. This night was employed in anxious deliberation upon what they had to do; at one time they resolved to land upon the isles; then they determined to make a descent upon the continent. In the very same instant they drew back in terror and gave themselves up to a wild joy; they could not come to any fixed determination, but changed their plans and their projects a thousand times. At daybreak Dandolo, Boniface, Baldwin, and the count de Blois ordered all the standards of the army to be unfurled; the escutcheons and coats of arms of the counts and knights were ranged along the vessels,[91] to display the military pomp of the West and recall to the warriors the valour of their ancestors. The signal was given to the fleet, which entered into the canal, and, driven on by a favourable wind, passed close to the walls of Constantinople. An immense population,[92] who only the day before were ignorant of the arrival of the Latins, crowded the ramparts and covered the shore. The warriors of the West, clad in complete armour,[93] stood erect upon the decks of their vessels;[94] some stones and arrows were launched from the towers and fell upon the ships: “there was no heart,” says Villehardouin, “so bold as not to be moved; for never was so great an affair undertaken.” Every warrior turned his eye towards his sword, thinking the time was come in which to make use of it. The Crusaders fancied that in the crowd of spectators they beheld the defenders of Constantinople; but the capital of the empire was only defended by the memory of its past glory, and by the respect of the nations ignorant of its weakness. Of true soldiers the imperial army only mustered two thousand Pisans, who despised the Greeks, and the troop of Varangians, mercenary soldiers from the northern parts of Europe, with whose origin and country the Greeks themselves were scarcely acquainted.[95]
