Within a square, or rather quadrangular, inclosure, attached to another of the same size, is a subterranean storehouse, or reservoir, which has been first excavated in the soil, then formed with rough stones, and lastly coated with an excellent cement, which is still in a very perfect state. The descent to this souterain is by a square well of trifling depth, which was so much overgrown and encumbered, as not to be immediately perceived. Having with us the means of procuring a light, we succeeded, without much trouble, in descending into the chambers which are excavated on each side of it, and in procuring the plan which appears in the plates. We were in hopes to have found some inscription on the walls, which we have already described as being very perfect, but nothing appeared but a few rude and unimportant Arab scrawls. In the neighbourhood of the military position, which we have noticed above, are the remains of the town already mentioned, called Medīna, where there are a number of wells and tanks in very good preservation; but the buildings above ground are in so mutilated and ruinous a state, as to render any satisfactory plan of them impossible, without a great deal of previous excavation. So little is mentioned by any writer (with whose works we ourselves are acquainted) of the buildings contained in the Syrtis, that it will for the most part be difficult to assign any other name to the remains of forts and towns at present existing there, than those by which the Arabs of the country now distinguish them. Charax is pointed out by Strabo as occurring after the tower of Euphrantas; but before the position of this town can be ascertained, it will be necessary to decide upon that of the tower itself, which, in a country presenting a continued chain of forts from one extremity to the other, is by no means very easily established. The Philæni[13] villa is also offered to our notice; but its position must depend upon that of the Philænean altars, which we are told by Pliny were merely of sand, and which we know were not remaining in the time of Strabo[14].
