Bosphorus into the higher part of the harbor. The distance is about ten [471] miles; the ground is uneven, and was overspread with thickets; and, as the road must be opened behind the suburb of Galata, their free passage or total destruction must depend on the option of the Genoese. But these selfish merchants were ambitious of the favor of being the last devoured; and the deficiency of art was supplied by the strength of obedient myriads. A level way was covered with a broad platform of strong and solid planks; and to render them more slippery and smooth, they were anointed with the fat of sheep and oxen. Fourscore light galleys and brigantines, of fifty and thirty oars, were disembarked on the Bosphorus shore; arranged successively on rollers; and drawn forwards by the power of men and pulleys. Two guides or pilots were stationed at the helm, and the prow, of each vessel: the sails were unfurled to the winds; and the labor was cheered by song and acclamation. In the course of a single night, this Turkish fleet painfully climbed the hill, steered over the plain, and was launched from the declivity into the shallow waters of the harbor, far above the molestation of the deeper vessels of the Greeks. The real importance of this operation was magnified by the consternation and confidence which it inspired: but the notorious, unquestionable fact was displayed before the eyes, and is recorded by the pens, of the two nations. [48] A similar stratagem had been repeatedly practised by the ancients; [49] the Ottoman galleys (I must again repeat) should be considered as large boats; and, if we compare the magnitude and the distance, the obstacles and the means, the boasted miracle [50] has perhaps been equalled by the industry of our own times. [51] As soon as Mahomet had occupied the upper harbor with a fleet and army, he constructed, in the narrowest part, a bridge,
