1. The exact form of the chlamys is unknown to us, but it was such, that its greatest breadth was to be found, if not exactly in, at least near, the middle of its length. The Habitable Earth being of the form of a Chlamys, its greatest breadth would be found about the middle of its greatest length.

2. The greatest length of the Habitable World being 70,000 stadia, its greatest breadth ought to be found at the distance of 35,000 stadia from its eastern or western extremity, but this greatest breadth is only 30,000 stadia, and it does not extend, on the north, beyond the parallel of the mouth of the Hyrcanian Sea. B. ii.

3. The meridian which passes at the distance of 35,000 stadia from the eastern or western extremities of the Habitable Earth, is that which, drawn from the mouth of the Hyrcanian Sea to the Northern Ocean, and prolonged in another direction through the mouth of the Persian Gulf to the sea called Erythræan, would pass through the city Artemita. Consequently it is on the meridian of Artemita that we must look for the greatest breadth of the Habitable Earth.

4. On this same meridian, we must reckon from the parallel of the last habitable country in the south to the mouth of the Persian Gulf, about 8000 stadia; then from the mouth of the Persian Gulf to Artemita, 8000 stadia; and from Artemita to the bottom of the Hyrcanian Sea, 8000 stadia: total 24,000 stadia.

5. It being established that the breadth of the Habitable Earth is 30,000 stadia, and not to extend it northwards beyond the parallel of the mouth of the Hyrcanian Sea, where it communicates with the Northern Ocean, the distance to this point from the bottom of this same sea must be calculated at 6000 stadia.

[1029] There are five islands off the Hiera Acta, which is now Cape Khelidonia. The Greeks still call them Cheledoniæ, of which the Italians make Celidoni; and the Turks have adopted the Italian name, and call them Shelidan. Smith, art. Chelidoniæ Insulæ.
