In appearance the protected enclosure, with its flanking ravines, has been described by some writers as a peninsular plateau, while to others it has suggested the shape of a table and seemed to justify the name of Trebizond (Trapezous). Neither likeness appears to me to be quite happily chosen. Both contain in themselves the conception of a disparity of levels, the plateau of a stage raised above the surrounding country, the table above the surface of the floor. Such are not the characteristics of the site. The metaphor of a table seems the more inappropriate, inasmuch as the least one might expect of such an object is that it should have a flat and horizontal top. This site possesses neither of these qualities. On the one hand, the upper portion, which supports the citadel, rises above the lower like a dais or step; while, on the other, the plane of the ground is an inclined plane, and follows the general configuration of the country, shelving from the hills towards the sea. Yet these images and the impressions from which they derive are no doubt founded upon real conditions. The isolation of the figure, together with its elevation--not indeed above the levels which adjoin it on either side, but above the level of the sea--these are the two factors which have supplied the real substance of such impressions. The first of these features would appeal to the eye with more distinctness, were it not for the thick growth of trees and underwood which rises from the floors and up the slopes of the ravines, and almost conceals the escarpment of their sides. The depth of the gulfs may be gauged by the following measurement made at the head of the western ravine. Standing at the bottom of the abyss, the rock which supports the citadel and palace overtops you by about 150 feet at the highest point. The width across them, from cliff to cliff, varies considerably, according as each gulf opens or closes in; the length of each of the two bridges which span the ravines is about 100 paces. Both ravines tend to flatten as they descend towards the shore, or in other words, to increase in width and diminish in depth. As for the elevation of the enclosure, it is of course most considerable at the narrow isthmus and the citadel. This highest portion, containing the keep and palace, is about 200 feet above the sea.
